Error description
A queue manager has a queue protected with Advanced Message Security(AMS) Message Channel Agent (MCA) interception. A client application that is trying to consume messages from the protected queue using a SVRCONN channel configured with SHARECNV greater than 1 receives one message and then repeated errors with Reason Code 2080(MQRC_TRUNCATED_MSG_FAILED) or no message and no error.
Local fix
Use SHARECNV=1 to workaround the problem
Problem summary
**************************************************************** USERS AFFECTED: Users using IBM MQ clients with SVRCONN channel(s) configured with SHARECNV greater than 1 and queue(s) protected with AMS MCA interception. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: A defect in IBM MQ buffer size and consumer state management when processing an AMS message on the queue manager side caused the consume state to be left in suspended state incorrectly and this resulted in the queue manager not delivering messages to the waiting consumer.
Problem conclusion
The IBM MQ code has been modified to correctly set the consumer state when processing AMS messages. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 LTS 9.1.0.10 v9.2 LTS 9.2.0.4 v9.x CD 9.2.5 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 ---------------------------------------------------------------
