Editing the Configuration File for Clustering

  1. Edit the nnsyreg.dat file that was created when you deployed to the server.

  2. Change the transport libraries from the server to client to allow remote access. For example, for WebSphere MQ, replace all instances of "dv41mqs" with "dv41mqc".

  3. Make this same change in the nnsyreg.dat file for every server in the ring.

 

Warning: An Error may be encountered when multiple sessions have CLASSPATH dependencies. For Example, session 1 will start the Java Virtual Machine (JVM) with its CLASSPATH; session 2 shares the JVM. Hovever, if the CLASSPATH requirements of session 2 are not met, it will fail. Two or more JMS sessions that run simultaneously must be defined in nnsyreg.dat to contain CLASSPATH information for all others, because the first one started determines the JVM environment for all sessions. To avoid failure, you must enter the same combined CLASSPATH for all sessions.
