IT27169: RDQM Queue Manager does not fail over if a symbolic link is usedfor the data directory (/var/mqm).

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).
