You can request a dump of a CICSPlex® SM address space at any time by:
You can issue the MVS DUMP command from the console to dump an Environment Services System Services (ESSS) address space, a CMAS, or a CICS®/ESA or CICS/MVS MAS. Use the ASID= keyword to identify one or more address spaces and the DSPNAME= keyword to request data space dumps.
If you request a dump of data spaces, you must also dump the DMDS sysid data space and the ESSS address space, because that component owns all CICSPlex SM data spaces. Data space names take the form:
cmpnsysid
where:
A sample dump command for a CMAS might look like this:
DUMP COMM=(CMAS DUMP)
R xx,ASID=(2A,55),CONT
R xx,DSPNAME=(55.DMDSHTC1,55.QUE1HTC1),END
You can use the SNAP action command on the CICSRGN view to request a system dump for a MAS in those CICS releases that support it..
For example, if you want a system dump for the MAS called EYUMAS1A, do the following:
