Error description
Dump Title: CSQ1,ABN=5C6-00F20042,U=SYSOPR ,C=W9700.800.XMC -CSQ2QCP0,M=CSQGFRCV,LOC=CSQ2IEPL.CSQ2QCP0+0000455C . RIDS/CSQ2IEPL#L Load module name: CSQ2IEPL RIDS/CSQ2QCP0 Csect name: CSQ2QCP0 AB/S05C6 System abend code: 05C6 PRCS/00F20042 Abend reason code: 00F20042 . Date Assembled: 20151116 Module Level: UI32981 Subfunction: XMC CSQ2QCP0OBTAIN . Abends similar to PI38007, however, PI38007 is applied. . This is slightly different to PI38007 in that in this case an MQBACK is returning MQRC_OUTCOME_PENDING which is not handled by CSQ2QCP0 and the 5C6-00F20042 occurs (PI38007 was for an MQCMIT).

Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 8 * * Release 0 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: When using the IMS bridge, abend * * 5C6-00F20042 or 5C6-00F20046 are * * produced if connectivity is lost to the * * CF structure hosting a shared queue * * used by the IMS bridge (either request * * or reply), when the IMS bridge * * processing attempts an MQBACK. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the IMS bridge is processing a message on a shared IMS request queue, or putting a message to a shared reply queue, it attempts an MQBACK for the unit of work. If the queue being used is hosted on a CF, and connectivity to that CF has been lost, the MQBACK will return with reason code MQRC_OUTCOME_PENDING. This should be considered a valid reason code, indicating that the MQBACK has been successfully issued. However IMS bridge processing treats reason code MQRC_OUTCOME_PENDING as an error, resulting in abends 5C6-00F20042 (CSQ2_QCP0_CLOSE_ERROR) and 5C6-00F20046 (CSQ2_QCP1_CLOSE_ERROR) from modules CSQ2QCP0 and CSQ2QCP1 respectively. Message CSQ2004E is also produced, indicating that the MQBACK has failed with MQRC=2124 (MQRC_OUTCOME_PENDING). Additional keywords: CSQ2004 MSGCSQ2004 MSGCSQ2004E CSQM065 CSQM065E MSGCSQ065 MSGCSQ065E PI38007
Problem conclusion
IMS bridge processing has been updated to correctly handle reason code MQRC_OUTCOME_PENDING returned during MQBACK processing, so that it no longer results in an error message and abend. 000Y CSQ2QCP0 CSQ2QCP1
