Improving region management
- Description:
- In V2R2, improved region management is supported in JCL. REGIONX
is a new JCL keyword available for the JOB and EXEC statements. It
allows the JCL coder to explicitly request exact below-the-line and
above-the-line storage amounts.
To support improved region management by the installation, a new parmlib member, SMFLIMxx, was introduced to establish rules for setting REGION and MEMLIMIT values, or for canceling the job step. This parmlib member can be used as a replacement for several functions of the IEFUSI exit.
The DISPLAY SMFLIM command displays the in-storage copy of the SMF limit rules, and the SET command updates the in-storage copy of the SMF limit rules.
- Release introduced
- z/OS V2R2 with APAR OA47062.
