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...
