Producing a dump using the standalone dump (SADMP)

The z/OS® operator can take a standalone dump of the entire system if z/OS fails. The operator receives a message when the SADMP completes.

This includes:

  • Suspending operation of the system.
  • Setting the address of the device containing your high-speed SADMP program, which you have generated to dump real and virtual areas.

    To dump virtual areas, code PROMPT on the AMDSADMP macro.

  • Performing a STORE STATUS.
  • Initiating the IPL of the standalone dump program. This program prompts you for:
    AMD001A TAPE=____
    AMD011A TITLE=______...______
    
  • Answering the prompts for dumping virtual storage areas:
    AMDO59D ENTER DUMP OPTIONS, 'LIST', OR 'END'.
    > dump CSA,ASID('IMSjobname','DL/Iname','DBRCname','IRLMname')
    AMDO59D ENTER DUMP OPTIONS, 'LIST', OR 'END'.
    > end
    AMD010I PROCESSING ASID=  ASCB= JOBNAME=*MASTER*
  • Waiting until the standalone dump program completes. The following messages signal completion:
    AMD005I  REAL DUMP DONE
    AMD025I  VIRTUAL DUMPING COMPLETE FOR CSA
    AMD010I  PROCESSING ASID=0001
    ⋮
    AMD023I  VIRTUAL DUMP COMPLETE - 00
Recommendation: Do not press the EXTERNAL INTERRUPT key before the dump completes because this could prevent the IMS Offline Dump Formatter from producing a formatted dump later.
