Preparing JES2 or JES3
Prepare the job entry subsystem on z/OS.
About this task
WebSphere® Application Server for z/OS® uses job entry subsystem (JES2/JES3) services like any other MVS™ application.
Procedure
- Identify the cataloged procedure library or libraries (proclibs) that you will use to hold cataloged procedures for WebSphere Application Server for z/OS. You might need to use separate proclibs for each system in a sysplex.
- If your system uses JES2 EXIT06 or JES3 IATUX03 to control specification of the REGION= value on JOB or EXEC statements, make sure that this control is relaxed for WebSphere Application Server for z/OS address spaces.
- If you plan to send WebSphere Application Server for z/OS trace output to the JES spool, make sure you have adequate spool space available. WebSphere Application Server for z/OS address spaces can produce a large number of trace records when tracing is activated.
