When you request a summary dump, the SUM parameter
requests many useful, predefined areas with one parameter.
Summary dump does not contain volatile system information. The
system writes the summary dump before it returns control to the dump
requester; the summary information is saved for each address space
that is being dumped.
The Summary Dump contains:
- ASID record for the address space of the dump task
- Control blocks for the recovery termination manager (RTM):
- RTM2WA associated with all TCBs in the dumped address space
- Dump header, which is mapped by AMDDATA.
For the AMDDATA mapping,
see z/OS® MVS™ Data Areas in z/OS Internet library.
- 4 kb before and 4 kb after:
- All valid unique addresses in the PSWs in the RTM2WAs shown in
the dump
- All valid unique addresses in the registers in the RTM2WAs shown
in the dump
- Supervisor control blocks:
- Current linkage stack
- Primary address space number (PASN) access list
- Work unit access list
For information about control blocks that are listed in Table 1, see z/OS MVS Data
Areas in z/OS Internet library.
