By clicking on administration Adapter we can see name of service and type(services/interfaces/libraries) and strength (hard/weak) columns of the service.

Administration Adapter – This service is part the of distributed services level of the JMX

(Java Management Extension) infrastructure. It provides a remote connection to theMBean server, as well as interfaces for working with the MBeans registered by the Basic

Administration Service.

Basic Administration – It provides instrumentation of the kernel and the server components (services,libraries, and interfaces). It also registers MBeans that can be used for management of a single clusternode or of the whole cluster.

Class Loader Viewer – This service graphically displays the relations between different loaders on aselected cluster element.

It enables you to manage the configuration manager and the configuration objects in the

database. It uses the interfaces that the configuration manager provides, enabling you to

access and modify configurations.

It is used to deploy small applications when SDM could not be used.

It manages the deployment of J2EE applications and the distribution of their modules to

the corresponding containers across the cluster.

It carries out the communication over http protocol and provides the functional http based

web server implementation. It is closely related to web server container service. And

represents the underlying communication module, that transfers http responses back to

the client.

It transfers information over an http protocol and provides features for proper remote

communication between the client and a particular service. If a proxy or a firewall

service stands between them.

It processes ABAP to Java requests. It dispatches the calls to a state less session Bean,

which is registered in the J2EE engine naming system.

It is used to communicate with external system like R/3, BI, CRM, SRM, APO, etc.,

Note:The specified program id should be unique to represent the connection between Web AS

and external systems.

It enables you to manage certificates and credentials on the J2EE engine.

It is installed through a text file, so, we have to download the test file from the market place.The license is a 24 digit key.We need to provide Hardware key, System ID, Release number, System type.

Or elseWe have generate suser ID, Customer number, Installation number.

It establishes the interface between the J2EE engine and Enqueue service.

It can display and manage locks, carry out tests and display statistics.

The locking adapter displays users locks and arguments, it is similar to SM12 in ABAP.

The locks can be deleted from the screen only based on approval.The options we have are Lock, Unlock, UnLock all, UnLock all counts, UnLock all with

wild cards.

It is used to configure the logs based on the requirement. Logs can be configured in two

areas.

1. Logs are stored in categories.

2. Traces are stored in locations.Log writes the events normally, not categories without any initialization.

Note:Log Severity

1. ALL

2. Debug

3. Path4. Info

5. Warning

6. Error 7. Fatal

8. None(We select Warning and Errors options only, do not select the ALL option (this willgenerate huge log file).

SQL Trace (http://hostname:50000/SQLTrace/index.html

It is used to identify the expensive SQL statements. We can use the web page display

trace or SQL trace option in log configurator service.

It is used by developers to identify the expensive SQL statements and fine tune.We can also monitor the traces in ABAP engine through ST03G.

It is to identify the logs.

It will be monitored in the work directory(D:\usr\sap\ABC\DVEBMGS00\work).

It displays based on the text, date/time, severity and Info.

It stores the information about the level of memory usage in J2EE engine.

Red – An error displays. Another threshold value has been exceed.

Green – According to the settings, the collected values are OK.

Yellow – The collected values have exceeded a pre-defined threshold value. A warningdisplays.

(This monitor service is similar to ST03(Work load analysis), ST04(Data base performance) in ABAP engine).

It provides the information about the SAP specific P4 protocol between Java remote

objects. This protocol is an alternative of the standard Java RMI (Remote Method

Invocation) protocol for Java to Java remote communication.

The port number for http – 50000

The port number for P4 – 50004

The port number for Telnet – 50008

The port number for SDM – 50018

Provides the ability to use traces for carrying out problems analyses. Through the

performance tracing runtime you can manage application traces, single activity traces

(SAT), Application response times, SQL traces and http sessions tracing.

CCMS Agent – Install the CCMS agent it is a piece of software available on the market

place to collect the information and send it to the ABAP system in XML format.

1. Application tracing (SE30) – It is used by developers to trace the activities.

2. Java Application Response Measurement (JARM) – ST03: It gives the request

summary, request overview, component overview, user overview, thread overview.JARM is an important role while measuring the response time of Java system. The

transaction GRMG (Generic Request Message Generator) used to view the SAP ABAP

system.Plug-ins – Distributed statistical records (DSR), it generates the information from the

Java engine and sends to ABAP engine for monitoring (as .xml documents).3. Trace config (ST01, ST05) – To activate the trace. It is used to switch on the

traces for single activities, SQL, JMS ((Java message service) adapter for

connecting to market place)), RMI (remote method invocation), HTTP, WEB,

EJB(Enterprise java beans), RFC.

4. Activities -

Applications and services can use this service. To encrypt and store sensitive data such

as passwords.

It is used to identify the logged on users. It is similar to SM04 on ABAP engine. There

are two types of security defined in Web AS Java.

1. Programatical approach (UME tool) – the security is controlled by Java developers

during the development. Permissions, Actions, Roles are defined in this approach(http://hostname:50000/usermanagement). These roles are referred as UME roles

and are assigned to Applications.UME STEPS:

User management store – it can be configured in UME, UDDI (universal description

and discovery integration), other database.

Java engine by default uses Security store.We can change the store by using security provider.

UME – where users are stored. When standalone engine is installed. It uses Java

database as UME. When Java plus ABAP engines are installed, it uses ABAPdatabase as UME. It can also be integrated with LDAP (it is configured in config

tool).

2. Declarative approach (VA tool)– the program’s security is not controlled by

developers. These programs are encapsulated and secured is implemented by an

.xml file. These roles are referred as J2EE security roles.

Here we can perform the locking and unlocking of the users(similar to SU01,SU10,SM04

in ABAP).

User Creation – Go to--- security provider Goto Runtime Goto User Management

Goto Change mode Goto Create user.

Role Assignment Goto Runtime Goto Policy Configuration Goto Security Role

NOTE: Here shows three types of Communication users by default.SAP*

SAP CPIC(Common Programming interface for communication)

SAP JSF (It is communicates between Java & ABAP Engine)

UME STEPS:

SU01 Create a user assign the Roles

SAP_BC_JSF_COMMUNICATION (communication user)SAP_BC_JSF_COMMUNICATION_RO (communicate user read only)

When both ABAP plus Java engines are installed together SU01 takes the role of user creation and assignment of roles.

The user should have the Authorization Role.

Path: http://hostname:50000/useradminSpecify the user and click on create. Go to assign the roles based on request an approval.

Select the user modify and display the available roles.

Select the roles and assign it to user and save.

Most of the Business packages comes with pre-defined roles. If these roles are assigneduser enabling to connect to other components.

Login session is to find the user who are logged in the system and terminated the session

based on approval (SM04 is the Tx in ABAP).

Provides telnet clients with remote administration using the telnet protocol, it offers a

distributed, scalable telnet server that supports remote shell administration performed by

telnet clients.

UME PROVIDER : It is an external security not an internal security.

Go to UME PROVIDER Services set the parameters like userid length(maximum,

minimum, password restrictions),
