Problem summary
**************************************************************** * USERS AFFECTED: * * All users of IBM MQ for z/OS Version 9 Release 0 * * Modification 0. * **************************************************************** * PROBLEM DESCRIPTION: * * MQMF_MSG_IN_GROUP unexpectedly set in MQMD.MsgFlags when * * putting a message with MQMD.MsgFlags = * * MQMF_LAST_MSG_IN_GROUP. * **************************************************************** * RECOMMENDATION: * * None * **************************************************************** When MQPUT/MQPUT1 is called to put a message, and passes a Version 2 MQMD with MQMD.MsgFlags set to MQMF_LAST_MSG_IN_GROUP, the queue manager treats this as if the MQMF_MSG_IN_GROUP were also specified. When the message is put to the queue, the MQMD associated with the message is correctly updated to show that both of these flags are set. The flags in the original MQMD should not be updated, and should continue to contain only MQMD_LAST_MSG_IN_GROUP, however an error in CSQMPUT causes the updated flags passed with the message to incorrectly be copied back in to the caller's MQMD.
Problem conclusion
CSQMPUT is changed to only copy back the output fields relating to message grouping when updating the MQMD passed on input to MQPUT/MQPUT1.
