    Multiple jvmRoute possible?

    Rajesh Chande Newbie

      Hello,

      I have a clustered environment with 2 JBoss instances (node1 & node2) in the cluster up and running fine with applications deployed on the same.

      I have Apache ----> JBoss (Apache forwarding requests to JBoss using Mod_jk.

      Apache - 2.0.55
      JBoss - 4.2.2GA
      mod_jk - 1.2.20

      Now I have a new application which needs to be deployed on a "standalone" JBoss instance.

      Can I use node1 from the cluster also as a standalone configuration by deploying the WAR file in the "deploy" folder instead of "farm" folder?

      For sending requests from Apache to JBoss 1, can i have the following configuration in server.xml as follows

      #################
       <!-- Define an AJP 1.3 Connector on port 8009 -->
       <Connector port="53041" address="${jboss.bind.address}" protocol="AJP/1.3"
       emptySessionPath="true" enableLookups="false" redirectPort="8443"
       maxThreads="200" connectionTimeout="600000" />
       <Engine name="jboss.web" defaultHost="localhost" jvmRoute="hubudweb-devl-01,worker1">
      #################


      This configuration works fine for me i.e. Jboss node1 works fine both as a clustered instance and a stand alone instance.

      So can I have multiple jvmRoute in use? Will this effect Session replication or Load Balancing in any ways?

      At times I get following error in Apache mod_jk logs:

      Is multiple jvmRoute th culprit for this error? What could be the reason for above error?
