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: It is unsupported to start a queue manager using transactional log files created or modified by a newer product version. In this scenario, or when the log files have been corrupted, additional validity checks were identified that allow for the generation of more appropriate error messages.
Problem conclusion
MQ code has been modified such that it generates a more meaningful error message if the queue manager is being incorrectly started using an older product version, and also when the log records are corrupted. --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.0 LTS 9.0.0.11 v9.1 LTS 9.1.0.7 v9.x CD 9.2.2 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 ---------------------------------------------------------------
