Preparing JES2 or JES3

About this task

WebSphere Application Server for z/OS uses job entry subsystem (JES2/JES3) services like any other MVS application. Follow these steps to prepare your job entry subsystem to run WebSphere Application Server for z/OS.

Procedure

  1. 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.

  2. 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.
  3. 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.
