Taking dumps

z/OS UNIX System Services Planning
GA32-0884-00

To initiate the dump, enter this command:
DUMP COMM=(dname)
where dname is a descriptive name for this dump. You can specify up to 100 characters for the title of the dump. The system responds and gives you a prompt ID. You reply by specifying the data to be included in the dump. If you specify the operand CONT, the system will prompt you for more input.

In the following examples of replies you can give, rn is the REPLY number to the prompt.

The data areas in the following reply contain system control blocks and data areas generally necessary for investigating problems:
R rn,SDATA=(CSA,SQA,RGN,TRT,GRSQ),CONT
In the next reply, x'E' is the OMVS address space. The other address space IDs specified are those believed to be part of the problem. You can specify up to 15 ASIDs.
R rn,ASID=(E,3A,32),CONT
This example specifies data spaces:
R rn,DSPNAME=('OMVS'.SYSZBPX2,'OMVS'.SYSZBPX1),END

The file system data space, SYSZBPX2, is useful if the hang condition appears to be due to a file system latch.

For more information about the DUMP command, particularly on specifying a large number of operands, see z/OS MVS System Commands.
