Problem summary
**************************************************************** * USERS AFFECTED: All users of WebSphere MQ for z/OS Version 7 * * Release 1 Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: The channel initiator issues message * * CSQX470E repeatedly for a shared * * channel after a CF structure failure. * **************************************************************** * RECOMMENDATION: * **************************************************************** When the channel was first started by a trigger message, riiTriggerMessage is invoked, and calls rriQueryChannelDisp to determine the channel disposition. The latter fails to open the shared transmit queue due to MQRC 2373 (MQRC_CF_STRUC_FAILED), however riiTriggerMessage does not check the return code and continues processing, adding a non-shared local status entry. This entry is used for retry processing, and when the CF structure is recovered, allowing the transmit queue to be opened again, channel start fails due to the channel having the wrong disposition, and message CSQX470E is issued.
Problem conclusion
The code was changed to correctly determine the channel disposition even if the CF structure has failed, allowing the channel to start correctly once the CF structure is recovered. 100Y CSQXRCDF CSQXRCSI
