Producing a dump using the z/OS DUMP command

The z/OS® operator can request a console dump at any time, whether or not IMS is terminating, by entering the DUMP COMM=description command.

z/OS responds with the following message:
xx IEE094D  SPECIFY OPERAND(S) FOR DUMP COMMAND
To which the z/OS operator must then reply with the following command:
xx,JOBNAME=(imsname,dbrcname,dliname,irlmname),
   SDATA=(PSA,NUC,SQA,RGN,CSA,TRT)
Unless you dump all specified areas, the IMS Offline Dump Formatter might not be able to format all desired IMS subsets of the dump.
