DUMP: Requesting a dump of the DFSMShsm address space

Explanation

DUMP is an optional parameter requesting a dump of the DFSMShsm address space before DFSMShsm stops processing. The SYSUDUMP, SYSMDUMP, or SYSABEND DD statement you specify in the DFSMShsm startup procedure determines where DFSMShsm sends the dump. If, however, you specify SETSYS SYS1DUMP, the DFSMShsm dumps resulting from an abnormal end or error condition are written in a system dump data set. Use caution when specifying the DUMP parameter on the STOP command when there is processing going on in a secondary address space. There is a large expenditure of system resources when processing in a secondary address space, and the DUMP parameter causes all secondary address spaces to end processing immediately.

Defaults

None.

Usage notes:
  1. When the STOP command is issued with the DUMP parameter in a sysplex environment, this host is eligible to have its functions taken over by another host.
