Using the DUMP command to request dumps
You can issue the z/OS DUMP command from the console to dump an
Environment Services System Services (ESSS) address space, a CMAS, or a MAS. Use the
JOBNAME=
or ASID=
keyword to identify one or more address spaces
and the DSPNAME=
keyword to request data space dumps. Use the
DSPNAME=
keyword with a data space name of *
, for example
DSPNAME=('EYUX560'.*)
, to select all data spaces for the ESSS address space unless directed otherwise by
IBM® support.
If you take a dump by using the DUMP command, ensure that you take a dump of the ESSS and its data spaces too. This is because the ESSS address space owns all CICSPlex® SM data spaces.
If you request a dump of data spaces, you must also dump the DMDS SYSID data space.
cmpnsysid
where: cmp
- Is either the three-character identifier of the component that uses the data space or DMDS, for the data cache main data space, which has controlling information for all data spaces. For a list of component identifiers, see Major components of CICSPlex SM and their 3-character identifiers.
n
- Is the sequential number of a component data space.
sysid
- Is the four-character system ID of the associated CMAS.

Sample DUMP command
The following example is a sample DUMP command that you can use:
DUMP COMM=(DumpTitle)
R xxx,JOBNAME=(cmas,mas1,mas2,EYUX###),DSPNAME=('EYUX###'.*),CONT
R xxx,SDATA=(ALLNUC,LPA,LSQA,PSA,RGN,SQA,TRT,CSA,GRSQ,SUM),END
where EYUX### is the version of CICSPlex SM you are using (for example, EYUX560).
You can add extra MAS names to the JOBNAME parameter as shown in this example.
