    Disabling Clustering in JBM 1.4.0(or in EAP 4.3)

     

    JBoss Messaging clustering is defined inside of the configuration file that establishes persistence(-persistence-service.xml) in the $/deploy/jboss-messaging.sar directory.    Note: when you configure messaging to use a different persistence, part of the instructions are to copy the -persistence-service.xml file for your database from the  docs/examples/jms/ directory and delete the hypersonic one.  Most of the configurations in docs/examples/jms contain entries to be clustered.  This wiki shows you how to disable clustering in the -persistence-service.xml file.  Step 1.  Open your $/deploy/jboss-messaging.sar/-persistence-service.xml file

     

    *Step 2.*  Look for the entry "

    "

     

    step 3.  change "

     

    step 4.  remove (or comment out) all of the rest of the attributes below your previous change(only delete down to the mbean close tag)

     

    to be deleted...
