OMEGAMON Subsystem fails with abend SDC4

Question & Answer


Question

The OMEGAMON Subsystem or Enhanced 3270UI (TOM) task abends with CODE=DC4 REASON CODE=91040120
What is the cause of this abend and how do I resolve it.

Answer

According to the IBM messages manual, abend CODE=DC4 REASON CODE=91040120 is an indication that a request for above the bar (64 bit) storage failed. The MEMLIMIT for the job needs to be increased.
If MEMLIMIT=NOLIMIT is already coded in the JCL for the job, then verify that an IEFUSI exit is not overriding the MEMLIMIT specification and limiting the job to a smaller amount of 64 bit storage usage allowed.
