There is not enough MVS storage available to satisfy an MVS GETMAIN request. See the explanation of system completion codes 878 and 80A to determine the type of storage being requested. Abend 0F9 and 40D can occur when MVS does not have enough storage to create the dump for the abend 80A or 878.

Resolving the problem

Collect this MustGather data before contacting IBM Support:

Collecting general information for all problems

If you have already contacted IBM Support, you can continue on to the component-specific MustGather information. Otherwise, go to Collect troubleshooting data for CICS products - Read first.

Collecting data for abend 878 or 80A problems

Required (MustGather) data:

  • MVS system dump taken at the point when there is an out of storage condition.
  • If you do not have a MVS system dump, set the following SLIP traps to get a SLIP dump of the abend 878 or 80A:



    where cicsjob is the name of your CICS job.
  • Alternatively, if you see gradual storage growth of MVS storage in the CICS region (excluding CICS DSA storage) you can take an MVS system dump of the region when storage usage is high. Use the MVS command followed by a reply:

    DUMP COMM=(dumpname)
    yy,JOBNAME=( cicsjob),

    where dumpname is the name you would like to give the dump, yy is the reply id, and cicsjob is the name of your CICS job.
  • MVS system trace that is included in the MVS system dump unless your installation has changed the IBM-supplied system tracing options. The trace should be at least 10240K. The failing GETMAIN could affect an innocent party that is not the cause of the storage leak. The large MVS trace should help identify the real culprit.

Optional (MustGather) data:
  • CICS message log showing the abend 878 or 80A.

Troubleshooting hints and tips

Diagnostic tips:

  • Review the logs and dumps generated at the point of failure.
  • Search the CICS support site for known problems using symptoms like the message number and error codes.
  • If you find a fixing PTF, see Ordering CICS products and maintenance for the options that are available to order CICS maintenance.
  • Gather the documentation and work with the CICS support team to resolve your problem.
