DFHZC2479 after PROG753 on a 3270 terminal when CICS sends a map

Troubleshooting


Problem

You receive a PROG753 and sense code 10030000 after your CICS application program does an EXEC CICS SEND MAP command. Sense code 1003 results in message DFHZC2479E or DFH2479I function not supported. You might also see an abend ATNI (abendATNI).

Cause

Map storage not initialized correctly from the LE routines because the LE Storage initialization options were not set correctly. If storage is not initialized, residual data will remain in the storage and be sent as part of the data stream to the terminal.

Resolving The Problem

Set the LE storage options to STORAGE=(00,NONE,00,0K) and storage will be initialized. The first 00 is for COBOL and second 00 is for PL/I or C. So if ALL your applications are written in COBOL, you should set the LE storage options to STORAGE=(00,NONE,NONE,0K) to initialize storage. Otherwise, CPU usage will be unnecessary increased due to the second 00 being set.

See Changing LE run-time options for CICS TS for more information about how to change the LE run-time options for your CICS TS regions.
