Error description
You have put on UK62750. You are still receiving abendAZI9. DFHAP0001 AN ABEND (CODE ---/AZI9) HAS OCCURRED AT OFFSET X'3042' IN MODULE DFHAPCR. A CPMI mirror task initiated from WebSphere Message Broker over an IPIC connection is purged due to a broker timeout while waiting for a response from another mirror task in a connected system. The application uses channels and containers to transmit data between programs. This results in (1) an AZI9 abend at offset x'3042' in DFHAPCR and (2) a subsequent SDUMP. The trace shows the task entering the IMPORT_CHANGED function just prior to the task being purged. Upon review of the dump, DFHZIS2 has issued a DFHPC ABEND AZI9 while DFHAPCR was attempting to receive the rest of the CHANNEL data from the server region. This causes DFHAPCR recovery routine to be driven which result in message DFHAP0001 and the SDUMP. The reason why it does not happen all the time is because when the TIMEOUT from the client is received in client region, the mirror task in that region is an IRLINK wait waiting on the response from the server region. The task gets force purged by the TIMEOUT resulting in the AZI9 abend and since we are not in DFHAPCR, no message DFHAP0001 and SDUMP are produced. . Additional Symptoms: KIXREVJXD

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: DFHAP0001 AN ABEND (CODE ---/AZI9) HAS * * OCCURRED AT OFFSET X'3042' IN MODULE * * DFHAPCR. * **************************************************************** * RECOMMENDATION: * **************************************************************** CICS takes an SDUMP AP0001 if the MRO DPL client task is purged when AP domain module DFHAPCR is in the process of waiting for a channel response from the DPL server task and a transaction abend AZI9 occurs.
Problem conclusion
DFHAPCR recovery routine is changed to add a check for abend code. SDUMP is taken only if the abend code is not 'AZI9'.
