Updating z/OS dump options

The sample JCL procedure for an HCL Workload Automation for Z address space includes a DD statement and a dump data set is allocated by the EQQPCS02 JCL created by EQQJOBS. SYSMDUMP is the dump format preferred by the service organization.

Ensure that the dump options for SYSMDUMP include RGN, LSQA, TRT, CSA, and GRSQ on systems where an HCL Workload Automation for Z address space will run. To display the current SYSMDUMP options, issue the z/OS command DISPLAY DUMP,OPTIONS. You can use the CHNGDUMP command to alter the SYSMDUMP options. Note that this command changes the parameters only until the next IPL is performed.

To dump an HCL Workload Automation for Z address space by using the z/OS DUMP command, the SDUMP options must specify RGN, LSQA, TRT, CSA, and GRSQ. Consider defining these options as your system default.

When dumping the controller address space, if JTOPTS CRITJOBS(YES) was specified or taken as the default, you must also dump the data spaces; this is important if you need to collect information when a critical path problem occurs. Add DSPNAME=('ZZZZ',*) to the DUMP command, where ZZZZ is the controller subsystem name.
