APAR status
Closed as program error.
Error description
Consider a scenario where requester/receiver/cluster receiver channel that has asked for a batch of messages, but a local target queue is full, lets assume we don't have DLQ's defined at either end. As we can't DLQ at the requester end, we reject the batch and the sender/server then states it also can't DLQ and sends us the ESH with rfpERR_CAN_NOT_STORE. In this scenario rrcI_MSGS_PUT_TO_REMOTE_DLQ(AMQ9544) is reported when the partner has sent an ESH of rfpERR_CAN_NOT_STORE instead of reporting rrcE_MSG_NOT_RECEIVED(AMQ9527). Reporting rrcI_MSGS_PUT_TO_REMOTE_DLQ when the partner has sent an ESH of rfpERR_CAN_NOT_STORE is incorrect as it means that the partner MCA has encountered one of rrcE_MQOPEN_FAILED rrcE_MQPUT_FAILED rrcE_NO_DLQ None of these could indicate a successful remote DLQ operation.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: All MQ users Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A programming error resulted in incorrectly reporting AMQ9544 error message in the scenario where AMQ9527 should be reported.
Problem conclusion
The MQ code has been modified to make an ESH containing rfpERR_CAN_NOT_STORE always issue rrcE_MSG_NOT_RECEIVED (AMQ9527) instead of reporting rrcI_MSGS_PUT_TO_REMOTE_DLQ(AMQ9544) for receivers, requesters and cluster receivers. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v8.0 8.0.0.12 v9.0 LTS 9.0.0.7 v9.1 CD 9.1.2 v9.1 LTS 9.1.0.3 The latest available maintenance can be obtained from 'WebSphere MQ Recommended Fixes' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006037 If the maintenance level is not yet available information on its planned availability can be found in 'WebSphere MQ Planned Maintenance Release Dates' http://www-1.ibm.com/support/docview.wss?rs=171&uid=swg27006309 ---------------------------------------------------------------
