APAR status
Closed as program error.
Error description
When using MQ with the RDQM High Availability feature and a symbolic link for the data directory (/var/mqm), the queue manager will not fail over to the remote appliance. MQ did not display the fact that this would occur and was not explicit in letting the user know that symbolic links are not supported.
Local fix
Do not use a symbolic link for the /var/mqm directory.
Problem summary
**************************************************************** USERS AFFECTED: Any users of the MQ RDQM HA solution with a symbolic link set up on their /var/mqm/ directory. Platforms affected: Linux on x86-64 **************************************************************** PROBLEM DESCRIPTION: At the time of issuing this APAR, RDQM HA does not support symbolic links on the MQ data directory (/var/mqm). The MQ system created the Queue Manager successfully and did not inform the user that this setup is not supported. Failover of the Queue Manager to a remote node would fail and it would be unknown to the user why this happened.
Problem conclusion
The code has been modified such that creating RDQM Queue Managers under a symbolic linked data directory will now fail with an error message (AMQ7077E). --------------------------------------------------------------- The fix is targeted for delivery in the following PTFs: Version Maintenance Level v9.1 CD 9.1.3 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 ---------------------------------------------------------------
