Using the DUMP command on z/OS
Follow the steps in this task to use the DUMP command on z/OS®.

- Control address space
- DataFlowEngine address space
- OMVS kernel address space
The following procedure demonstrates how to dump the DataFlowEngine address space. This procedure is the same for any of the address spaces.
- Find the address space ID of the address space that you
want to dump using the display command on the z/OS syslog:
This command displays the address spaces of all the processes that are running from your started task user ID, for example:D OMVS,U=your started task user ID
The infrastructure main program bipimain is the first process in every address space. For a control address space, bipimain starts the bipservice process, which starts the bipbroker process, which might also start the biphttplistener process, depending on the configuration. For a DataFlowEngine address space, bipimain starts the DataFlowEngine process. For each execution group, an additional DataFlowEngine address space is started. In this example, only one execution group is deployed.D OMVS,U=MQ01BRK BPXO040I 16.14.30 DISPLAY OMVS 237 OMVS 000D ACTIVE OMVS=(14) USER JOBNAME ASID PID PPID STATE START CT_SECS MQ01BRK MQ01BRK 009D 67306064 84083282 HRI--- 15.41.55 48.37 LATCHWAITPID= 0 CMD=bipservice MQ01BRK AUTO MQ01BRK MQ01BRK 009D 84083282 1 1WI--- 15.41.55 48.37 LATCHWAITPID= 0 CMD=/argoinst/S000_L30307_P/usr/lpp/mqsi/bin MQ01BRK MQ01BRK 009D 16974444 67306064 HRI--- 15.42.01 48.37 LATCHWAITPID= 0 CMD=bipbroker MQ01BRK MQ01BRK MQ01BRK 009F 16974445 1 1W---- 15.42.05 2914.22 LATCHWAITPID= 0 CMD=/argoinst/S000_L30307_P/usr/lpp/mqsi/bin MQ01BRK MQ01BRK 009F 33751662 16974445 HR---- 15.42.05 2914.22 LATCHWAITPID= 0 CMD=DataFlowEngine MQ01BRK ca614eec-f300-000
- Use the z/OS DUMP
command to dump the DataFlowEngine address space, which is shown in
the above example as 9F.
- Enter the following command:
The console returns:DUMP TITLE=(DFE)
*`15 IEE094D SPECIFY OPERAND(S) FOR DUMP COMMAND
- Enter:
The console returns:R 15,ASID=9F,CONT
*16 IEE094D SPECIFY OPERAND(S) FOR DUMP COMMAND
- Enter:
The console returns:R 16,SDATA=(CSA,RGN,PSA,SQA,LSQA,LPA,TRT,GRSQ,SUM),END
The dump is stored in either a pre-allocated dump data set called SYS1.DUMPxx, or an automatically allocated dump data set named according to an installation-specified pattern.IEE600I REPLY TO 16 IS;SDATA=(CSA,RGN,PSA,SQA,LSQA,LPA,TRT,GRSQ,SUM),END IEA794I SVC DUMP HAS CAPTURED: 356 DUMPID=014 REQUESTED BY JOB (*MASTER*) DUMP TITLE=DFE IEF196I IGD101I SMS ALLOCATED TO DDNAME (SYS00018) IEF196I DSN (SYS3.DUMP.ARG5.#MASTER#.T142958.S00014 ) IEF196I STORCLAS (SMS) MGMTCLAS (DUMP) DATACLAS ( ) IEF196I VOL SER NOS= ARGSMR
- Enter the following command:
- In some scenarios, all address spaces for a given broker,
that is, all those listed in the example above, plus the OMVS address
space and dataspaces, are needed by IBM to
resolve the problem. Use the z/OS DUMP
command to dump all MQ01BRK address spaces.

You can also find information on
the individual thread by issuing the DISPLAY z/OS console command, as in the example:
