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.
