The SDUMP options needed to support the CICS dump exit
The CICS dump exit is unable to format a CICS dump successfully unless the minimum SDUMP options are in force at the time the dump is written.
CICS issues an SDUMP macro request specifying a number of SDUMP
options, of which the following must not be overridden:
- ALLPSA
- All prefixed storage area for all processors
- COUPLE
- Cross-system coupling facility (XCF) information
- CSA
- Common service area
- GRSQ
- Global Resource Serialization control blocks
- LPA
- Link pack area modules
- NUC
- Non-page-protected areas of the DAT-on nucleus
- RGN
- Private area of the address space being dumped (this includes the LSQA and SWA)
- SQA
- System queue area
- SUMDUMP
- Summary dump
- TRT
- GTF, system trace, and main trace data
- WLM
- Workload Manager areas
If you set the dump mode for SDUMP to override mode (using the MVS™ CHNGDUMP SET OVER command), you must ensure that at least these options are set in the system’s SDUMP options list.
