Error description
You are getting an abend0C4 program check protection exception in DFHM321$ at offset x'2140'. The failing instruction is a: 947F1033 NI TCTTETF3,255-TCTTESMF to turn off send map flag. The 0C4 occurs if a transaction running under the Link3270 Bridge issues an EXEC CICS RECEIVE INTO request followed by EXEC CICS RECEIVE MAP FROM . The code in DFHM321$ attempts to use a TCAFCAAA containing zero to address a TCTTE. This then leads to a program check when attempting to turn off the TCTTESMF flag in the BMS extension.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users * **************************************************************** * PROBLEM DESCRIPTION: abend0C4 DFHM321$ at offset x'2140'. * **************************************************************** A CICS region is running with the BMS 3270 Intrusion Detection Service (IDS) active. A transaction running under the Link3270 Bridge issues an EXEC CICS RECEIVE INTO request followed by an EXEC CICS RECEIVE MAP FROM request. DFHM321$ incorrectly attempts BMS IDS checking which is not applicable when running under the Link3270 Bridge. This leads to an 0C4 because it assumes there is a TCTTE BMS Extension and this does not exist in the Bridge environment.
Problem conclusion
DFHM321$ is changed to bypass BMS IDS checking for an EXEC CICS RECEIVE MAP FROM request issued by a transaction running under the Link3270 Bridge.
