Error description
A queue manager is started with a particular MQ version. Then the user reverts back to a lower MQ version and then starts the queue manager. If the log record version is different between the MQ version versions, the queue manager could fail to start with unexpected errors that are not helpful to understand the problem. Similar problem might also occur because of corrupted queue manager log records.
Local fix
Problem summary
**************************************************************** USERS AFFECTED: Users starting queue manager after reverting back MQ from higher MQ version to lower MQ version or with corrupted log records Platforms affected: MultiPlatform **************************************************************** PROBLEM DESCRIPTION: MQ did not check log record version before processing the log record causing unhelpful error messages during queue manager startup failure.
Problem conclusion
MQ code has been generated to check the log record version before processing the log record, in order to generate a more meaningful error message if the queue manager is being incorrectly started using an older product version. It remains invalid to start a queue manager at a lower version (CMDLEVEL) than the level at which it was previously run. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.0 LTS 9.0.0.11 v9.1 LTS 9.1.0.6 v9.x CD 9.1.5 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 ---------------------------------------------------------------
