602: XCGLOBAL_GETMAIN_ERROR

During Initialize_User processing, a GETMAIN failed for a critical control block (XCGLOBAL).

System Action

Processing cannot continue without this control block, and the request is terminated. At this point the external CICS® interface trace and dump services are not available to provide diagnostic information, therefore EXCI issues an MVS abend (U0403) to force a SYSMDUMP. The return code from the MVS GETMAIN request is returned in the return area.

User Response

Locate the GETMAIN return code in the dump, and use this and the rest of the dump to determine why the GETMAIN failed. A possible reason for this is that the region size specified for the job is too small. If this is the case, increase the region size and restart the client application program.
