Practices for Lesson 1

The goal of the practices in this lesson is to investigate and identify the various business processes that you can define and associate with the purchase order processingapplication. Deduce a workflow diagram by segregating different task and business

processes in a sequential flow for the purchase order processing business processscenario.

In this practice, you specify the missing links in the given processes workflow diagramfor the purchase order processing business process scenario.




Practice 1-1: Specifying Tasks in Workflow for a Purchase OrderProcessing Business ScenarioIn this practice, you specify the missing links in the purchase order processing business

process workflow diagram.

The POProcessingComposite SOA composite is described in the following sequence ofsteps.

1. Details of the purchase order are received.2. Small order quantities (quantity less than 10 units) are approved automatically.3. Large order quantities (quantities greater than or equal to 10 units) pass through a

validation and approval process (where the customer’s credit card status isvalidated).

4. If the credit card status is invalid, the order is rejected and the status informationis written to a text file.

5. If the credit card status is valid, the total order amount is evaluated.

6.

If the total order amount is less than $5000, the order is auto-approved and theorder details are written to the text file.7. If the order amount is greater than or equal to $5000, the order passes through a

manual approval process.8. If the status of the manual approval is “approved,” the order details are written to

a text file with the status approved.9. If the status of the manual approval is “rejected,” the status detail (rejected) is

written to the text file.

Based on the application description, fill in the missing business process links (annotatedwith question marks) in the following business process flow diagram.

The goal of the practices in this lesson is to create the r out ePO Mediator servicecomponent. The client that interacts with the SOA composite makes a new purchaseorder request to the POProcessingComposite by using the r ecei vePO Web serviceinterface. The r out ePO Mediator routes the order request to a text file ( or der _n. t xt )

by using the Wr i t eAppr oval Resul t s File adapter.

Often, you have an application or some GUI-based front end to invoke and test a service;however, usually, when you start developing your services, you do not have any clientapplication to test them. The Oracle Enterprise Manager 11 g Fusion Middleware Controlconsole allows you to run your service with any input, so you can test it at any time.

In this practice set, you perform the following tasks:1. Create a Mediator service component to route the purchase order to a text file.2. Add routing rules and map the order request to the text file.3. Deploy and test the SOA composite in Oracle SOA Suite 11 g .

i) On the Oracle Enterprise Manager 11 g Fusion Middleware Control page, yousee two vertical panes. In the left pane, you see the domain and under it a listof folders. Expand the SOA > soa-infra (soa_server1) folder. You seePOProcessingComposite.



iv) In the Test Web Service page, scroll down to the Input Arguments section andselect XML View from the drop-down list. Delete the existing XML code inthe text area in the XML view.

v) Open the text file ( po- l ar ge- i Pod. t xt ) atD: \ l abs\ Appl i cat i on_Fi l es\ t est by using any text editor (such asnotepad), and copy the XML code.

vi) On the Test Web Service page, paste the XML code in the text area of theXML view.

vii) Click the Test Web Service button.c) Verify the result of testing the POProcessingComposite SOA composite.

i) On the Test Web Service page, under the Response tab, verify that the TestStatus is Passed.






ii) Click the POProcessingComposite link in the left pane of the browser dialog box. You see that an instance has been added under the Recent Instancessection.


iv) In the Flow Trace page, under the Trace section, verify that the State columnshows completed for the service, component, and reference.

v) You can also verify the result by opening the new text file ( or der _n. t xt )that has been created by the File adapter service at theD: \ l abs\ Appl i cat i on_Fi l es\ t est Resul t s directory with a texteditor.

3) Retest the SOA Composite using the same input data, but this time, change the creditcard number to 4321- 4321- 4321- 4321 , which represents an invalid credit card.

4) Observe the order status in the new text file that has been created by the File adapterservice at the D: \ l abs\ Appl i cat i on_Fi l es\ t est Resul t s directory. TheinvalidCreditCard status is the result of the <swi t ch> statement in theappr oveLar geOr der BPEL process.





5) Close the Web browser window.






The goal of the practices in this lesson is to add and configure a Human Task componentin the POProcessingComposite SOA composite. The Manual POAppr oval Human Taskis accessed by the approveLar geOr der BPEL process for manually approving large

orders that have a valid credit card status.

When the Human Task is added to the <case> branch of the Eval uat eCCSt at us Switch activity, a t askSwi t ch activity is also added at the same time as the HumanTask. The t askSwi t ch is configured with an <otherwise> branch and a <case> branchfor each outcome configured in the Human Task. In this practice, you add activities foreach branch in the t askSwi t ch .

In addition, by using JDeveloper you generate a simple task form to display purchaseorder information in the Worklist application for the assignee approving the order.

In this practice set, you perform the following tasks:1. Create a Human Task in the POProcessingComposite to manually approve large

orders.2. Access and configure the Human Task in the appr oveLar geOr der BPEL

process.3. Deploy and test the SOA composite in Oracle SOA Suite 11 g .




The following diagram illustrates the tasks to perform in this practice set.

Note: The outputVariable has all the information collected so far.

f) Click OK to close the Create Human Task dialog box.

3) Add an Assign activity in the <case Task outcome is APPROVE> part of thet askSwi t ch Switch activity (if the request is approved). Ensure that you expand theSwitch activity (by clicking the + icon) before adding the Assign activity.

Note: Notice that there are two new activities in the BPEL process: a Human Taskand a Switch activity ( t askSwi t ch ). The Human Task handles getting the approval(or rejection) from users using a Worklist application. The Switch activity is used toevaluate the results from the Human Task, such as the task being approved, rejected,withdrawn, or expired.





a) Drag the ass i gnAppr oval Assign activity below the CopyPayl oadFr omTask Assign activity in the <case Task outcome is APPROVE> branch of thet askSwi t ch Switch activity.

Note: The approved case was already created earlier while constructing theappr oveLar geOr der BPEL process. Therefore, you can reuse that.

4) Specify the message in the <case Task outcome is REJECT> part of the t askSwi t ch Switch activity (if the request is rejected).

a) Double-click the CopyPayl oadFr omTask Assign activity in the <case Taskoutcome is REJECT> branch.

c) Click OK.

d) Click OK to return to the BPEL process.

6) Create the task form for task details that includes the task payload and actions youdefined in the task.

Note: The task form is an ADF form that is created in a separate project. You cancreate a JSF project to manage the task form and point it to the task file that youcreate in your composite. When you want a default task form, it is a simple one-clickoperation.

a) In the BPEL process, right-click the Manual POAppr oval _1 Human Taskactivity and select the Auto-Generate Task Form option from the shortcut menu.





b) Enter Appr oveTaskDet ai l in the project name field for the task form and clickOK. JDeveloper generates the necessary artifacts for the ApproveTaskDetail

project (it may look like nothing is happening at first, but be patient). You see thetask details form ( t askDet ai l s1. j spx ) open.





c) Save all and close the task form and task flow dialog box.

7) Save and close the BPEL process.




Practice 9-3: Deploying and Testing the SOA Composi teIn this practice, you deploy the POProcessingComposite SOA composite application tothe application server. You also test the SOA composite by using the Oracle EnterpriseManager 11 g Fusion Middleware Control console.In the BPEL practice set, you create a large order, which the Mediator routes through theappr oveLar geOr der BPEL process. In this practice, you use the default Oracle BPMWorklist application to approve the order.

1) Deploy the ApproveTaskDetail project to Oracle SOA Suite 11 g .

a) Click the Applications Menu icon (next to Application_09) and select the Deploy> ApproveTaskDetail > to > MyApplicationServerConnection option from thelisted options.

Note: Never deploy the application by right-clicking the ApproveTaskDetail project and selecting the Deploy option from the shortcut menu. It is not a SOAComposite application.

b) In the Select Deployment Targets dialog box, select “soa_server1” and click OK.







a) In the Application Navigator menu of JDeveloper, right-clickPOProcessingComposite (the SOA project) and select the Deploy >POProcessingComposite > to > MyApplicationServerConnection option.

b) In the SOA Deployment Configuration dialog box, select the “Overwrite anyexisting composites with the same revision ID” option and click OK.Note: If you are redeploying your application with the same revision number, youmust select the option to overwrite the previous version or enter a new version(revision ID). Otherwise the deployment will fail.

ix) Click the POProcessingComposite link in the left pane of the browser dialog box. You see that an instance has been added under the Recent Instancessection.

x) Click the Instance ID to see the flow trace of the composite.

xi) In the Flow Trace page, under the Trace section, notice that the State columnshows the Running status, the Mediator, BPEL, and the Human Workflowcomponent.

c) Approve the order by using the Oracle BPM Worklist application. OracleWorklist application is an application that can be used to view and manage humantasks.

i)

Open a Web browser and log in to the Oracle BPM Worklist application byspecifying the following URL:

ht t p: / / l ocal host : 8001/ i nt egr at i on/ wor kl i st app .

ii) Enter the user name as webl ogi c and the password as wel come1 . ClickLogin.





iii) In the Oracle BPM Worklist page, click the most recent task to highlight it.The task details page opens it in the lower frame of the work list application.

Note: The first time the task is opened, there will be a delay of a minute whilethe pieces of the form are compiled and loaded.

iv) When the form opens, you can see the task details and the different options.From the Actions menu, select Approve. This submits the task and notifies theBPEL to continue processing.

Note: You should use the Actions menu to select the task to approve or reject.If instead, you use the Approve or Reject buttons in the lower part of thedialog box, the screen will not change even though the task is submitted. Clickthe refresh icon at the top left to clear the task from the screen.





4) Revisit the Oracle Enterprise Manager 11 g Fusion Middleware Control console andrefresh the Flow Trace page. You see that the State column shows a Completed statusfor all the service components.

Hint: Check the date and time of the text file to view the most recent file created bythe file adapter.



Practice 9-3: Deploying and Testing the SOA Composi te(continued)


6) Execute the same test case again, and reject the order in the Oracle BPM Worklistapplication. Verify the result.









The goal of the practices in this lesson is to add and configure a Business Rulecomponent in the POProcessingComposite SOA composite. The Manual Appr oval Business Rule is accessed by the appr oveLar geOr der BPEL process to make the

decision of whether the human task is required for manual approval. If the total ordervalue is more than or equal to $5000, a customer service representative must manuallyapprove the order.

In this practice set, you perform the following tasks:1. Create a Business Rule component in the POProcessingComposite to specify the

condition of manually approving only those orders that have the order value ofmore than or equal to $5000.

2. Access and configure the Business Rule component in the appr oveLargeOr der BPEL process.

Introduction to Linux


http://slidepdf.com/reader/full/soa-suite-11g-essential-concepts-volume-2 170/230Oracle SOA Suite 11 g : Essential Concepts B - 2


What Is Linux?

• Linux is a UNIX-based operating system, created by Linus

Torvalds at the University of Helsinki in Finland.• It was developed under the GNU General Public License,

allowing source code to be freely available.• Each distribution was developed for a particular purpose.• TUX, the penguin, is the official mascot of Linux.

What Is Linux?Linux is an operating system that was initially created as a hobby by Linus Torvalds, a student atthe University of Helsinki in Finland. Torvalds had an interest in Minix, a small UNIX system,and decided to develop a system that exceeded the Minix standards. He began his work in 1991when he released version 0.02, and worked steadily until 1994 when version 1.0 of the Linuxkernel was released.

Linux is developed under the GNU General Public License and its source code is freelyavailable to everyone. As a result, a number of companies, organizations, and individuals havedeveloped their own “versions” of the Linux operating system, known as distributions.

Each distribution, with associated programs and utilities, was developed for a particular purpose— for example, on computers that receive heavy traffic (such as Web page servers),where security is a priority, or on top of an existing operating system (such as Windows) so that

people can try out Linux under familiar conditions.

Although Linux is technically only the kernel, it is commonly considered to be all of theassociated programs and utilities of a distribution.

Linux has an online manual containing descriptions for all commands (see the man utility).




What Is Oracle’s Strategy for Linux?

The following distributions are certified and supported by

Oracle:• Red Hat Enterprise Linux AS and ES• UnitedLinux, which includes the following products from

Conectiva, SCO, SuSE, and TurboLinux: – Conectiva Linux Enterprise Edition powered by UnitedLinux – SCO Linux Server 4.0 powered by UnitedLinux – SuSE Linux Enterprise Server 8 (SLES 8) powered by

UnitedLinux – TurboLinux Enterprise Server 8 powered by UnitedLinux

What Is Oracle’s Strategy for Linux?Oracle is fully committed to supporting the Linux operating system. In fact, Oracle was the firstcommercial database available on Linux. By supporting Linux with Oracle’s industry-leading

products, Oracle Corporation enables customers to deploy enterprise-class solutions on the leastexpensive hardware and operating system infrastructure. With technical contributions to enhanceLinux, with direct support of the key Linux operating systems, and with strategic partnerships,Oracle is offering an Unbreakable Linux platform for customers to safely deploy Linux in amission-critical environment. Oracle’s delivery of a complete solution, including direct technicalsupport of the operating system, is critical to the customer’s success.

Red Hat Enterprise Linux AS, version 2.1

Red Hat has been working with Oracle Corporation to provide a more reliable and scalable platform for enterprise Linux users, which resulted in Linux AS, version 2.1. It includes many ofthe same packages as Red Hat 7.2, but also includes enhancements for enterprise features.

UnitedLinux

UnitedLinux is the result of a consortium of Linux vendors. It is based on the SuSE kernel andsupports asynchronous input/output.




File System and Basic Directory Structure

In Linux, there are directories, subdirectories, and files—but

everything is just a file.

File System and Basic Directory StructureEvery Linux user has a login username and password. Each user is provided with a separateworkspace. In Linux, there are directories, subdirectories, and files; but everything is just a file.Some key directories are:

• /bin : The /bin directory contains programs, also known as binary files.• /boot : The /boot directory contains the Linux kernel.• /dev : The /dev directory contains the devices that your system uses or can use.

Everything is considered a file in Linux, so your hard disk is kept track of as a file that sitsthere. Your hard drive will be known as /dev/hda .

• /etc : The /etc directory contains most of the configuration files for Linux.• /lib : The /lib directory contains library files. Linux stores library files here for

systemwide shared access to libraries.• /root : The /root directory is a restricted area for all users except those with root

privileges. The root privilege allows users to perform all system functions. See the sucommand for instructions on obtaining root privileges.

• /sbin : The /sbin directory contains programs (binary files) used by root .• /tmp : The /tmp directory is used to store temporary files.



File System and Basic Directory Structure (continued)• /usr : The /usr directory contains files and programs that are used by all users on the

system.• /var : The /var directory is for certain files that may change their sizes (that is, variable

size)—for example, databases or incoming email from an email server.




Shell Commands

• Environment-based commands

• Information-based commands• File system commands• Common vi editing commands• Common FTP communication commands• Archive utilities

Shell CommandsAll operating systems use a shell to get commands from the keyboard to the computer. The most

popular shell used for Linux is the bash shell; bash means “Bourne Again Shell.” It is a freeversion of the Bourne shell.

For quick reference, the commands are divided as follows:• Environment-based commands• Information-based commands• File system commands• Common vi editing commands• Common FTP communication commands• Archive utilities




Environment-Based Commands

Information-Based CommandsThe usage for information-based commands is as follows:

• > : Redirect output- Usage: ls > filename (lists all files in a directory and writes them to a file called

filename . If filename already exists, the contents are overwritten, otherwise a new fileis created.)

• >> : Append contents- Usage: ls >> filename (The output is written to the end of filename . If filename

does not already exist, it is created.)• | : A “pipe” for redirecting the output of a command to another command

- Usage: ps –ef | grep keyword (displays all processes containing keyword )• cat : Concatenate files and print on standard output

- Usage: cat filename (displays the contents of filename to the screen)• diff : Find the differences between two files

- Usage: diff file1 file2 (displays the difference between file1 and file2)• file : Determine file type

- Usage: file filename (displays the file type—for example, text or executable)



Information-Based Commands (continued)• find : Find files

- Usage: find –name *oracle* (finds all files containing “oracle”)find –mmin –10 (finds all files created in the last 10 minutes)

• grep : Find words in files- Usage: grep –ir ‘oracle’ filename (searches for “oracle” in filename ,

ignoring case [the –i directive] and searching directories [the –r directive])• info : Provide information on a specified topic

- Usage: info ls (displays an information page with multiple topic nodes)- Del/Space (moves to the previous/next page within the current topic)- n/p (moves to the next/previous topic node)- m topicname (moves to a specific topic)

• less : Display contents of a file, allowing backward and forward scrolling- Usage: less filename (Use “f” to move forward, “b” to move backward, and “q” to

quit.)- diff file1 file2 | less (displays the difference between two files and pipe the results

through “less”)• ls : List storage (that is, display the contents of the current directory)- Usage: ls –al (lists all files in the current directory)

ls –al *html (lists all HTML files in the current directory)• man : Display a manual page

- Usage: man find (displays the manual for the find command)• more : Display contents of a file

- Usage: more filename (uses SPACE to move forward and “q” to quit.)ls –al | more (lists the directory and pipe the results through more )

• pwd : Print working directory

- Usage: pwd (shows the full path of the current directory)




File System Commands

• cd

• chmod• chown• cp

• mkdir

• mv• rm• rmdir

File System CommandsThe usage for file system commands is as follows:

• cd : Change directory- Usage: cd /dir/files (changes into the /dir/files directory)- cd directoryname (changes into the directoryname directory located under the

current directory)- cd ../directoryname (changes into the directoryname directory located above the

current directory)• chmod : Change the permissions on a file or directory

- Usage: chmod 7777 filename (grants read, write, and execute permissions to allusers accessing filename ; computes the octal number as follows: read (4), write (2),execute (1) and identifies the user’s access positionally, through the letters “ugoa”where (u) is the user who owns it, (g) is for other users in the file’s group, (o) is forother users not in the file’s group, or (a) for all users)



File System Commands (continued)• chown : Change the owner or group for a file

- Usage: chown owner:group filename (changes the owner and group of filename tothe current user)

• cp : Copy files- Usage: cp file ../newFile (copies file into the directory above the current directory

and renames it as newFile )• mkdir : Make directory

- Usage: mkdir newdir (makes a new directory newdir under the current directory)- mkdir /usr/ newdir (makes a new directory newdir under the /usr directory)

• mv : Move (rename) files- Usage: mv oldName newName (renames oldName as newName )

• rm : Remove files- Usage: rm filename (removes filename from the current directory)- rm *old (removes all files ending in “old”)

• rmdir : Remove directories

- Usage: rmdir directoryname (removes directoryname from the current directory)

Archive Utilities

The following archive utilities are available for Linux:

• tar• gzip and gunzip• bzip2 and bunzip2• zip and unzip

Archive UtilitiesThe following archive utilities are available for Linux:tartar stands for tape archive and was originally designed for tape backups, but is used to create atar file anywhere on the file system. The tar utility creates one “tar file” (also known as a“tarball”) out of several files and directories. A tar file is not compressed. It is just a heap of filesassembled together in “one container.” So, the tar file takes up the same amount of space as allthe individual files combined, plus a little extra. A tar file can be compressed by using gzip orbzip2 .

The following are some examples:• tar -cf backup.tar /home/ftp/pub : Creates a tar file named backup.tar

from the contents of the /home/ftp/pub directory• tar -tvf example.tar : Lists the contents of example.tar to the screen• tar -xvf example.tar : Extracts the contents of example.tar and displays the

files as they are extracted• tar -zxvpf my_tar_file.tar.gz : Unzips the tar file and then extracts the

contents



Archive Utilities (continued)The options are defined as follows:

• -c : Create an archive.• -f : Use the file in question (required option).• -p : Preserve dates, permissions of the original files• -t : List the contents of an archive.• -v : Verbose (that is, tar informs you what files it is extracting)• -x : Extract files from the tarball.• -z : Unzip the file first.

gzip and gunzipThe gzip utility compresses a tar file, reducing the amount of space required to store thearchived tar file. The gunzip utility (or gzip –d ) expands (decompresses) the gzip file.gunzip recognizes the special extensions .tgz and .taz as shorthands for .tar.gz and.tar.Z , respectively. The following are some examples:

• gzip my_tar_file.tar : Compresses the tar file and renames it with a .gzextension

• gzip -d my_tar_file.tar.gz : Zips the tar file• gunzip my_tar_file.tar.gz : Unzips the tar file

bzip2 and bunzip2The bzip2 utility compresses files by using the Burrows-Wheeler block sorting textcompression algorithm and Huffman coding. Compression is generally considerably better thanthat achieved by more conventional compressors. The bunzip2 utility (or bzip2 –d )decompresses a bzip2 file.

The following are some examples:• bzip2 * : Compresses each file in the current directory and renames the file with a .bz2

extension• bunzip2 my_file.bz2 : Decompresses the my_file.bz2 file• bzip2 –d my_file.bz2 : Decompresses the my_file.bz2 file

zip and unzipzip is a compression and file-packaging utility for UNIX, VMS, MS-DOS, OS/2, Windows NT,Minix, Atari and Macintosh, Amiga, and Acorn RISC OS. It is compatible with PKZIP (PhilKatz’s ZIP for MS-DOS systems). The companion program “unzip” unpacks zip archives. Thezip and unzip utilities can work with archives produced by PKZIP, and PKZIP and PKUNZIPcan work with archives produced by zip.

The zip program puts one or more compressed files into a single zip archive, along withinformation about the files (name, path, date, time of last modification, protection, and checkinformation to verify file integrity). An entire directory structure can be packed into a ziparchive with a single command. Compression ratios of 2:1 to 3:1 are common for text files.

The following are some examples:• zip my_files * : Creates a compressed file named my_files.zip , containing all

the files in the current directory• unzip my_files.zip : Expands the zip file within the current directory




Shortcuts and Tips

• Case-sensitivity

• The clear utility• Shift + Page Up/Page Down• Tab• Color coding• The touch utility

• Web sites

Shortcuts and Tips• Linux is a case-sensitive operating system. You must enter the case correctly.• In the terminal window, to clear the contents, enter clear .• To scroll up, press Shift + Page Up.• To scroll down, press Shift + Page Down.• Press Tab to complete the remainder of the text. (Linux beeps to let you know that is as far

as it can complete the text; you now need to add more characters to resolve ambiguities.)• When you enter ls –al , the result is color coded. Blue is for directories.• To create a file, enter touch filename . If the file name does not exist, it gets created. If

the file name already exists, touch alters its time stamp to the current time. Note that, inLinux, you cannot easily name files with spaces in them, therefore, you must useunderscores or a capital letter to separate words. For example, “ touch my file” does notwork. You must write either “ touch myFile” or “ touch my_file.” This applies tocreating directories as well.

SOA Adoption Planning Principles


http://slidepdf.com/reader/full/soa-suite-11g-essential-concepts-volume-2 206/230Oracle SOA Suite 11 g : Essential Concepts D - 2


Objectives

After completing this lesson you should be able to:

• Describe the SOA adoption planning activities• Identify the need for an SOA Reference Architecture• Understand the stages in the development of the SOA

Reference Architecture




SOA Adoption

• SOA adoption will require most companies to change their

business model, which requires a matching modification oftheir technology infrastructure.

• In order to overcome the barriers and challenges to SOA,a well-structured SOA organizational governance needs tobe established.

SOA AdoptionAs many enterprises seek to expand their SOA initiative, there are fundamental issues that must

be considered in SOA adoption planning. Businesses continue to struggle with the issue of bridging the business and IT gap. SOA can help bridge that gap by focusing on delivering business services that the business can understand, rather than programs and systems. The focuson services delivering business functionality assist in aligning business and IT.

The benefits of SOA do not come automatically and there are a number of areas and disciplinesthat need to be addressed. These areas include developing and executing an SOA strategy,understanding and managing the demands that a shared infrastructure brings, and understandingthe organizational commitments required for SOA to deliver the benefits that it extols. Ifenterprises do not address these demands, then they will encounter a number of challenges inexecuting their SOA program.




SOA Adoption Planning Activities

• Getting and sustaining commitment

• Driving measurable adoption through the SOA program• Leveraging the technology• Defining a phased change approach

SOA Adoption Planning ActivitiesThe various SOA adoption planning activities can be discussed as follows:

• Getting and sustaining commitment: This activity involves:- Completing the stakeholder community- Moving through the change curve- Sustaining focus through “line-of-sight” goals

• Driving measurable adoption through the SOA program: This activity involves:- Establishing a governance model- Generating pipeline and milestone delivery- Using metrics to accelerate adoption and ensure “line-of-sight” goals

• Leveraging the technology: This activity involves the following:- Ensuring SOA capabilities will continue to enable business innovation- Providing tools and processes will improve ease of use and drive adoption- Emphasizing the need for an SOA Reference Architecture for the entire enterprise




SOA Adoption Planning Activities: Completingthe Stakeholder Community

In order to reach out to all stakeholders to achieve a greater

level of compliance, you need to prioritize the following actions:• Complete stakeholder mapping and define roles and

responsibilities• Ensure that stakeholders understand that driving and

enforcing may be needed• Raise the stakes to help people through the change• Ensure that a consumer group is established to work as

part of wider SOA team

SOA Adoption Planning Activities: Completing the Stakeholder CommunityIn order to reach out to all stakeholders, the stakeholder community must include consumer

personnel equally with IT delivery personnel. Executives need to understand that their role is toenforce and drive transformation to SOA as much as its support. The consumer group that isestablished needs to work as a part of the SOA team in order to identify services and map tocapabilities. In addition, if the key leadership of an organization is only supporting the SOAinitiative, it is destined to fail. In fact, a wider and deeper evangelism and commitment isneeded.






SOA Adoption Planning Activities: Establishing"Line-of-Sight" Goals

To develop the overall strategy, prioritize the following actions:

• Establish guiding principles• Establish measurable “line-of-sight” goals in accordance

with guiding principles• Consider a rewards/enforcement system

SOA Adoption Planning Activities: Establishing "Line-of-Sight" GoalsSOA adoption planning best practices:

• Set pragmatic SOA guiding principles that simply encapsulate the high-level vision• Ensure that “line-of-sight” goals are in place and tracked; explain why this is important• Set bold, aggressive goals whose “line of sight” can be rolled up to the following

principles:- Culture-changing behaviors, quality, and so on- Base measurement and reward systems on these value-adding outcomes




SOA Adoption Planning Activities: Establish aMilestone Delivery Plan

In order to establish a Milestone Delivery Plan, prioritize the

following actions:• Perform an analysis of the projects pipeline to show how

using SOA can support these projects• Seek a Chief Technology Officer (CTO) mandate if needed

to use SOA services in these projects• Drive adoption by prioritizing a few “trailblazer” projects to

demo early success

SOA Adoption Planning Activities: Establish a Milestone Delivery PlanThe SOA adoption plan will be overwhelming to most stakeholders if there is no recognizablemilestone delivery plan in place. If a project pipeline is established early on to include these“trailblazer” prototype projects, delivery efforts are likely to be far more successful because ofthe iterative feedback available from implementation successes as well as the failures along theway.

The best practices that can be followed are:• Drive adoption by prioritizing a few “trailblazer” projects to demo early success• Capture results to feed in lessons learned, continue process improvement, and simplify the

adoption level of effort




SOA Adoption Planning Activities: Usage ofMetrics

The usage of metrics is vital to understand the progress of SOA

adoption. The actions to be prioritized are:• Decide which metrics will prove SOA benefits/value and

adoption progress• Develop benchmark capabilities and requirements for SOA

adoption to make progress measurement more real• Develop cost/benefit modeling tools to inform future

investment decisions

• Define metadata standards for metrics instrumented intoall SOA assets

SOA Adoption Planning Activities: Usage of MetricsDeveloping a simple “dashboard” to show progress as well as to capture important trends

provides a greater incentive for key stakeholders. The following are best practices that you canfollow:

• Benchmark key metrics now to allow real progress tracking later.• Because service-enabled capabilities are used more widely, it is important to demonstrate

value at the individual service level.• Non-financial benefits, such as reduced time-to-market, shorter release cycles, and the

number of services, are as key as financial benefits.




SOA Adoption Planning Activities: EnablingBusiness Innovation

Services that are mapped to business processes are key to the

success of the SOA initiative. In order to ensure that SOAcapabilities continue to enable business innovation, prioritizethe following actions:• Define and enable a service identification process that will

avoid frequent and often costly service version updates• Model business processes going forward to enhance the

prospect of service reuse and enable the business processto the service feedback and optimization loop

SOA Adoption Planning Activities: Enabling Business InnovationThe following are best practices that you need to follow to ensure that SOA capabilities continueto enable business innovation:

• Ensure business user representation in the stakeholder group.• Enhance the prospect of innovation with appropriate service reuse.• Define well understood business/engineering aligned processes to address service

identification, service prioritization, and service granularity.




SOA Adoption Planning Activities: Usage of Toolsand Processes

In order to drive SOA adoption, the proper use of tools and

processes is vital. Under this activity, prioritize these actions:• Communicate, educate, and align best practices and

frameworks to consumers by building a referenceapplication

• Standardize on content and document management• Provide processes, tools, and utilities to ease learning and

to enable repeatability

SOA Adoption Planning Activities: Usage of Tools and ProcessesThe following are the best practices that you need to follow to enable the proper use of tools and

processes:• Make common frameworks and other identified patterns standard across IT.• Publish best practices so that consumers approach tasks consistently.• Provide the development and design tools along with the appropriate training and

mentoring to enable the realization of the various methodologies.




The Need for an SOA Reference Architecture

• An SOA Reference Architecture defines the target

architecture and the principles to be used by anorganization’s architects to make architecture and designdecisions on their projects.

• An SOA Reference Architecture should include a definedset of relevant IT, industry, and enterprise standards alongwith a glossary establishing a common vocabulary withwhich to discuss a particular problem space and relevantsolutions.

• It should include multiple views, derived from viewpointsaddressing the concerns of many stakeholders (not justother architects).

The Need for an SOA Reference ArchitectureThe SOA Reference Architecture provides a high-level view to a desired outcome on a three-year planning window. This is a “living” document and incremental releases of the SOAReference Architecture will be produced at regular intervals during the execution of an SOAroadmap. The SOA Reference Architecture anchors architectural concepts, links principles andguidelines, and requirements and motivation, to establish a consistent framework for theelaboration of concrete architectures for specific SOA implementations. A critical aspect of anSOA Reference Architecture is to establish a link to business drivers, including relevantmotivation derived from a business plan, in addition to traditional requirements. Other relatedwork, including standards, patterns and so on, is often shared by other enterprise planningartifacts and may not be exclusively within the SOA Reference Architecture itself.




Developing the SOA Reference Architecture

Stages in the development of the SOA Reference Architecture:

Align IT withbusiness

Develop abaseline

CreateReference

Architecture

Createinfrastructure

roadmap

Developing the SOA Reference ArchitectureSeveral key individuals will be involved across the various planning and design stages toinclude:

• Business executives (or IT liaisons) provide business drivers for the SOA ReferenceArchitecture

• IT executives provide IT objectives, O&G model, funding model, and project listinformation

• Enterprise architects provide current reality and future vision architecture and roadmapguidance

These activities can be categorized into four general stages:• Align IT with business• Develop a baseline• Create the SOA Reference Architecture• Create the SOA infrastructure roadmap




Developing the SOA Reference Architecture:Align IT with Business

The goal at this stage is to fully capture business needs by:

• Gaining an understanding of important business driversthat affect the direction of IT

• Discussing IT objectives with reference to business drivers• Discussing SOA benefits and challenges with higher-level

business executives• Prioritizing SOA benefits based on business and IT drivers

Developing the SOA Reference Architecture: Align IT with BusinessThe primary set of activities involved in this stage include:

• Organizing a kickoff session to plan future activities• Collecting business drivers and IT objectives from all stakeholders• Discussing perceived SOA benefits and challenges• Formalizing, distributing, reviewing, and finalizing the analysis

This first set of activities is used to collect business and IT drivers that affect the SOA ReferenceArchitecture decisions related to the future vision. It also serves to collect benefits andchallenges that management perceives to be associated with SOA. The results are factored intothe SOA Reference Architecture planning sessions and listed in the SOA Reference Architecturedocument.




Developing the SOA Reference Architecture:Develop a Baseline

The goal at this stage is to complete an assessment of your

SOA readiness by cataloging and documenting the current:• IT environment, key systems, technologies, and products• SOA initiatives, service developments, and supporting

infrastructure• IT organization, governance, and funding models• Level of support (or resistance) for current SOA initiatives

Developing the SOA Reference Architecture: Develop a BaselineThe primary activities at this stage include:

• Collecting information on enterprise architecture and technology• Collecting information on current and future projects• Producing an SOA assessment and readiness document

The results will establish a baseline for gap analysis. In order to provide a starting point for theSOA infrastructure roadmap, all key stakeholders need to obtain an understanding of the currentstate of IT. An assortment of activities may be used to properly document information on thecurrent enterprise architecture, infrastructure, technologies, and products, as well as ITorganizational structures, governance, and project funding models. This stage involves all keystakeholders, with extra emphasis on the technical staff and enterprise architects, as mostinformation gathered pertains to areas of technology. A document that provides the assessment,readiness, and “current-state” of the organization is produced, which is later used as a starting

point for the infrastructure roadmap.




Developing the SOA Reference Architecture:Create SOA Reference Architecture

The goal of this stage is to:

• Leverage collective thought leadership to define yourorganization’s future SOA vision

• Document the vision as your SOA Reference Architecture

Developing the SOA Reference Architecture: Create SOA Reference ArchitectureThe primary activities at this stage include:

• Training or mentoring employees with less SOA experience• Developing planning sessions to specify future vision architecture, principles, guidelines,

infrastructure, technologies, products, and so on• Formalizing, distributing, reviewing, and finalizing the complete vision document which

becomes the enterprise’s SOA Reference Architecture

The goal is to establish an SOA Reference Architecture for the organization, aligned with business strategy and drivers to guide future projects toward a common SOA vision. The SOAReference Architecture is a higher level of abstraction than ordinary project architectures, as it ismeant to provide guidance to all projects as opposed to being a specification for any one project.The SOA Reference Architecture represents a desired future vision, approximately two to threeyears into the future.




Developing the SOA Reference Architecture:Create SOA Infrastructure Roadmap

The goal at this stage is to:

• Provide an incremental plan for achieving the future vision• Synergize efforts with current and future projects

Developing the SOA Reference Architecture: Create SOA Infrastructure RoadmapThe primary activities at this stage include:

• Performing the gap analysis relative to your current baseline• Reviewing projects for infrastructure build-out and infrastructure services construction• Mapping gaps, projects, and deliverables to roadmap phases• Producing the SOA infrastructure roadmap and distributing it to all relevant stakeholders

It is important to provide a roadmap to plan the build-out of SOA infrastructure, for example,infrastructure assets, such as service bus, registry, and security products, and commoninfrastructure services, such as security, logging, and error handling services. Certain legacyapplication access services may also be included, as appropriate. The roadmap includes one tothree current or future projects identified for deployment on the SOA infrastructure in theroadmap planning horizon.

The roadmap helps to drive agility through the specification of standards-based development andcommon reusable interfaces and helps to maximize the flexibility and reusability of existingapplications and infrastructure.

The roadmap helps both to realize reliability, scalability, availability, and security across theenterprise and to enable the on-going management of the SOA Reference Architecture andoverall SOA initiative.




SOA Governance Model

It is important for an organization to have an SOA Governance

model in place, in order to :• Maximize the reuse of services• Minimize the duplication of business functionality in

services• Maximize the business value of services• Maximize the efficiency of creating new services or

modifying existing services

• Define the available services and their functionality• Clearly state what services are available and what

functions they perform

Example of an SOA Governance ModelThe slide describes an example of an SOA Governance Model consisting of the followingstructures:

• SOA Steering Committee: It comprises the executive stakeholders in IT delivery and provides the overall guidance for SOA adoption, including the prioritization of investmentin services and the funding of the delivery of those services and the shared infrastructureon which they operate.

• SOA Architecture Group: This group is responsible for setting the overall technicaldirection for SOA adoption and for measuring compliance against that direction as servicesare delivered.

• SOA Architecture and Advisory Team: This group provides the function of spottingopportunities for building or harvesting services, for advertising the availability of servicesto enterprise constituent, and for monitoring compliance in the use of services.

• Service Functional Analyst: This group seeks to provide the link between business needsand IT development project proposals, specifically business service capabilities anddefinitions.

• Service Development Team: This group is chartered with developing services that areinfrastructural in nature and that benefit the entire customer organization, spanning all ofits business units.




Summary

In this lesson, you should have learned how to:

• Describe the SOA adoption planning activities• Identify the need for an SOA Reference Architecture• Understand the stages in the development of the SOA

Reference Architecture• Define the need of SOA Governance Model

enterprise. EAI may involve developing a total new view of an enterprise's

business and its applications, seeing how existing applications fit into the new

model, and then devising ways to efficiently reuse what already exists while

adding new applications and data.

EDL: Event Definition Language.

EDSOA: Event Driven Service Oriented Architecture. An architecture that combines

SOA’s request-response and Event-Driven Architecture’s (EDA) event publish-

subscribe paradigms.

EJB: Enterprise Java Bean. Defines a Java API for server-side enterprise components

that execute within a J2EE-compliant applicant server. The specification alsodetails remote communication protocols, persistence, transactions, concurrency

control, naming services, and deployment descriptors.

ETL: Extract Transform Load. The processes that enable companies to move data from

multiple sources, reformat and cleanse it, and load it into another database, a data

mart, or a data warehouse for analysis, or onto another database, a data mart, or a

data warehouse for analysis, or onto another operational system to support a

business process.

IAAS: Information as a Service

IIOP: Internet Inter-ORB Protocol. An open-standard protocol published by OMG to be

used for communication in CORBA-based systems.

JAM: Java Applications Manager. Enables launching Java Applications.

JAXB: Java Architecture for XML binding. Provides a convenient way to process XMLcontent using Java objects by binding its XML schema to Java Representation.

JCA: Java Connector Architecture. A J2EE-based technology standard for connecting

application servers and enterprise information systems (EIS).




JMS: Java Messaging Services. A Java API for interacting with messaging-based

systems. The API supports both the point-to-point (and queuing) and

publish/subscribe interaction models. It is the primary standard to provide a

reliable foundation for loosely coupled, asynchronous messaging within a

distributed environment.

LOB: Line of Business

Mashup: Web page or application that combines data or functionality from two or more

external sources to create a new service

MDS: Metadata Service Repository. It is a critical component of SOA, providing a

shared location to manage metadata and govern the asset life cycle.

MOM: Message-Oriented Middleware. The term for application communication

software that connects systems in a network by carrying and distributing

messages between them. The messages may contain data and/or software

instructions. MOM infrastructure is typically built around a queuing system that

stores messages pending delivery and keeps track of whether and when each

message has been delivered.

MTOM: Message Transmission Optimization Mechanism. It is a method of efficiently

sending binary data to and from Web services.

OASIS: Organization for the Advancement of Structured Information Standards. An

international consortium that drives the development, convergence, and adoption

of e-business standards. The consortium produces Web services standards and

standardization efforts in the public sector and for application-specific markets.

Portlet: Pluggable user interface software components that are managed and displayed in

Web portals.

REST: Representational State Transfer. A collection of network architecture principles

that outline how resources are defined and addressed.




RFID: Radio Frequency Identification

RMI: Remote Method Invocation. A RPC protocol published for accessing Java object

methods remotely within a distributed application system.

ROI: Return On Investment. A performance measure used to evaluate the efficiency of

an investment or to compare the efficiency of a number of different investments.

RPC: Remote Procedure Call. A protocol used in the client-server model that allows one

application (the client) to request a service from another application (the server)

located on another computer in a network without having to understand network

details.

SCA: Service Component Architecture

Schematron: A rules-based XML Schema language that uses XPath expressions to

describe validation rules.

SDO: Service Data Objects. A data programming architecture and API for the Java

platform that unifies data programming across data source types (relational

databases, entity EJB components, XML sources, Web services, JCA, JSP),

provides robust support for common application patterns, and enables

applications, tools, and frameworks to move easily, query, view, bind, update, and

introspect data.

SLA: Service-Level Agreement. A contract between a service provider and a service

requester that stipulates a specified level of service. An SLA could contain

agreements on support options, enforcement or penalty provisions for services not

provided, a guaranteed level of system performance, availability, and other

quality-of-service (QoS) standards.

SMTP: Simple Mail Transfer Protocol

SOAP: Simple Object Access Protocol. An XML-based messaging protocol maintained

by W3C that is used to encode the information in Web service request and




response messages before sending them over a network. SOAP messages are

independent of any operating system or protocol and can be transported using a

variety of protocols, including HTTP and JMS.

Stateless: Having no information about what occurred previously. Most applicationsmaintain state, which means they remember what users were doing the last time

that they ran the application, and they remember all of the configuration settings.

In contrast, the Web is intrinsically stateless because each request for a new Web

page is processed without any knowledge of the previous pages requested.

UDDI: Universal Description, Discovery, and Integration. An OASIS standard for a

platform-independent, XML-based registry to publish and discover network-based

software components and services.

WLST: WebLogic Scripting Tool

WSDL: Web Services Description Language. A standard language for defining a Web

service description, which uses XML and XSD to describe the port type and its

operations, the message formats, and the protocol bindings.

WSFL: Web Service Flow Language. It is an XML language for the description of Web

services compositions.

WSIF: Web Services Invocation Framework. It is a simple Java API for invoking Web

Services.

WSIL: Web Services Inspection Language. It is an XML document format to facilitate

the discovery and aggregation of Web service descriptions in a simple and

extensible fashion.

XSD: XML Schema Definition. A W3C recommendation to formally describe the

schema and elements in an XML document. An XSD defines a structure for the

custom elements and their corresponding attributes, their relationship to each

other, and what types of information/data may be contained in them. This can be



used to verify that the content of an XML instance document adheres to a

particular schema.

XSLT: Extensible Stylesheet Language Transformations (XSLT) is the language used in

XSL style sheets to transform XML documents into other XML documents
