In the Active/Standby configuration, Node1 is the primary LifeKeeper server. It protects the WebSphere MQ queue managers. All storage resides on a NAS server with the IP While Node2 may be handling other applications/services, it acts only as a backup for the WebSphere MQ resources in LifeKeeper’s context. The directory /var/mqm is located from the NAS server’s IP and mounted on the active node only. The primary server can run as many queue managers as it can handle.

Configuration Notes

  • The clients connect to the WebSphere MQ servers using the LifeKeeper protected IP designated to float between the servers in the cluster.
  • The directory /var/mqm is located on the NAS server.
  • The active server mounts the directory /var/mqm from the NAS server with IP using a dedicated network interface.
  • There are heartbeats configured on each network interface.
  • Each queue manager has modified the listener object to contain a unique port number.
