RIDS/CSQXRCTL#L RIDS/#UNKNOWN AB/S00C4 PRCS/00000011 REGS/06378 REGS/30306 . Symptom Description ------- ----------- RIDS/CSQXRCTL#L Load module name: CSQXRCTL RIDS/#UNKNOWN Csect name: #UNKNOWN AB/S00C4 System abend code: 00C4 PRCS/00000011 Abend reason code: 00000011 REGS/06378 Register/PSW difference for R06: 378 REGS/30306 Register/PSW difference for R03:-0306 . The change team reviewed the doc and they can see that the 0C4 occurs after applying the PTF for PM56506 when a SVRCONN is using compression and an MQGET returns MQRC 2033. . This is the same problem as fixed at V710 by PM67996.

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 0 Modification 1. * **************************************************************** * PROBLEM DESCRIPTION: Abend 0C4 in CSQXRCMP when a client * * application issues MQGET with a Version * * 3 MQGMO using a channel with * * COMPHDR(SYSTEM). Error message * * 'CSQX112E xxxx CSQXDISP Dispatcher * * process error, TCB=xxxxxxxx reason= * * 0c4000-00000011' is issued to report * * the error. * * This abend may cause the channel * * initiator to terminate. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the channel initiator responds to an MQGET request it builds an MQGET segment containing the MQGMO to return. As the channel being used is configured for header compression rriCompress is called to compress the segment prior to transmitting it across the network. rriCompress incorrectly calculates the length of RLELength (length to encode) as FFFFFFF4 (i.e. -12 or a huge positive number). The reason for the incorrect length is that the TSH being compressed is an MQGET reply with a version 3 GMO. However, rriSizeofMQGMOSwap returned the length of a version 4 GMO, which is 12 bytes longer. This large length causes an overlay of storage and an ABEND0C4 in CSQXRCMP. An ABEND0C4 in CSQXBNT1 is another possible symptom due to rriCompress attempting to trace the GMO using the incorrect MQGMO length. Following the error, further instances of the channel may fail to connect to the channel initiator with reason MQRC 2537 (MQRC_CHANNEL_NOT_AVAILABLE) until the channel initiator is restarted.

Problem conclusion
UK78367 UK80313 UK83468 rriSizeOfMQGMOSwap is corrected to return the correct length of a version 3 MQGMO to rriCompress. 010Y CMQXRSRV CSQXCCAX CSQXRCMP
