410: DFHMEBM_LOAD_FAILED

During Initialize_User processing, the external CICS® interface attempted to load the main message module in preparation for issuing external CICS interface messages, and the load of this module failed.

Explanation

System Action

The Initialize_User call is rejected. The return code from the MVS™ load macro (R15) is returned in the subreason field-1. The external CICS interface handles the error, and returns the abend (R0) that would have occurred in the subreason field-2.

User Response

Using the MVS return code, determine why the load failed. The most likely reason is that the message module, DFHMEBMX, is not in any library included in the STEPLIB of the batch job. Ensure the CICSTS54.CICS.SDFHEXCI library is included in the STEPLIB concatenation, and restart the client application program.
