Main messages from the simplification announcement
IBM is investing in mainframe simplification and modernization:► System Management: We�re making z/OS
systems easier to set up, operate, and administer
► Application Development: We�re delivering a modern, easy to use development environment.
IBM is partnering with clients and schools to build the pool of mainframe-savvy IT professionals:
► IBM Academic Initiative for System z
► z/OS Basic Skills Information Center

Example of z/OS task simplification Scenario: System Configuration
► Customer wants to enable a new network security feature
Without task automation � high degree of expertise is assumed:
► Customer reads manuals (perhaps several) to understand how to implement the new feature
► Customer verifies that all functional pre-requisites are met
► Customer edits configuration files (perhaps several)
► Customer tests the configuration change before putting it into production
With task automation:
► Customer opens the z/OS management console and selects the network security feature she wants to enable. The �Network Configuration Assistant�takes over:
● Verifies that pre-requisites are met● Prompts for the minimum amount of information needed; applies �best practice�
values for as many configuration settings as possible
● Updates configuration files during a change window selected by the user
► Customer tests the configuration change

z/OS Management Console Future Directions*
IBM is moving to a common web console solution for administering servers � including z/OS, z/VM, and Linux on System z.
This console will be an integration point for all management tasks.
Tasks such as health monitoring and software updates will have a common look and feel across server platforms.
The underlying system management infrastructure will be open so that vendors can also exploit it. (This is the role of the z/OS Common Information Model (CIM) element in z/OS 1.8).
* IBM development plans are subject to change or withdrawal without further notice.

The New Face of Application Development for z/OS
Eclipse is the most used IDE today (see Eclipse.org)
► Many commercial products based upon it
► Many Universities use it to teach programming
► �Eco-system� of users � see the various projects available
The �new face� of z/OS application development is based upon Eclipse � provides integration opportunities that never existed!
WebSphere Developer for System z (WDz) extends Rational Application Developer to provide access to one or more z/OS systems
► Communication via TCP/IP
► SAF Authentication
Goal is to make application development on z/OS as easy as it is perceived on other platforms
► Leverage what is familiar
► Leave the �fear factor� to the TV series and remove it from application development on z/OS
Provide easy artifact manipulation on z/OS � support:
► PDS, Sequential Files, HFS, JES, TSO Command prompt, USS Shell commands

z/OS Application Programmer�s Experience Today
1. Start 3270 emulator
2. Logon to the z/OS system
3. Navigate to the dataset and member using ISPF
4. Select the member for editing
5. Locate the line in the source code
6. Change the source code and save the member
7. Switch to the JCL that is used to submit and schedule the compile job
8. Submit the JCL job
9. Switch to SDSF to monitor the job and review the output
10.Repeat 5-9 until program runs correctly
Scenario: Correcting an error in a COBOL source file
