[jboss-user] [JBossCache] - Re: Configuring JBossCluster

[bstansberry@jboss.com]

The clustering configuration comes from the ClusterConfig element, not from anywhere in WLS.

That element defines a JGroups protocol stack.  See http://www.jgroups.org/javagroupsnew/docs/manual/html/index.html for general JGroups documentation.

Each subelement within the stack defines a particular protocol.  See pages linked from http://wiki.jboss.org/wiki/Wiki.jsp?page=JGroups for a discussion of what each protocol does and what the config options are.

In brief, if you are using UDP, all servers on the network with the same mcast_addr and mcast_port config will see each other and form a group.  If you are using TCP, you need to list your servers in the TCPPING protocol, or use the MPING protocol.
