Error description
When putting messages to a WebSphere MQ Advanced Message Security 7.0.1.12 queue manager, some of the all messages received are corrupt. . WMQ trace of the message channel agent (MCA) shows the valid messages are put by the same RCVR channel thread. The messages which are invalid are received and put by a second thread. That indicates the MCA is using pipelining. The Channel stanza in the qm.ini file shows PipeLineLength=2, which confirms the use of pipelining.
Local fix
Do not use the Channel stanza parameter PipeLineLength=2 with WMQ 7.0.1.12 Advanced Message Security.
Problem summary
**************************************************************** USERS AFFECTED: Users implementing Advanced Message Security (AMS) and setting the PipeLineLength=2 parameter (pipelining) in the qm.ini Channels stanza. Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: Encrypted messages received over a channel with pipelining in use have an extra AMS header added when put to the destination queue. This means that the message cannot be properly read from the queue. Attempts to read the message with conversion result in MQRC_FORMAT_ERROR.
Problem conclusion
Ensure that messages do not have additional AMS headers added by channels using pipelining. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v7.0 7.0.1.13 v7.1 7.1.0.7 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 ---------------------------------------------------------------
