I have a code which is making a n IIOP call to access an MQ resource "connectionFactory"  using a URL like this iiop://hostname:bootstrapport/.



Here bootstrapport number is of the JVM to which the connectionFactory is scoped to.  Now what is the bootstrap port number/host names I need to be using   if the connectionFactory is scoped to a  cluster with more than  one JVMs.

IF I need to use each  JVM and port, will the code  look like this (iiop:hotsname1:bootstrapport, iiop:hotsname2:bootstrapport, iiop:hotsname3:bootstrapport3). If this is right, will this failover incase if needed.

hi,
You must use following link:

iiop:host1:port1,:host2:port2,:host3:port3

You can use this piece of code:

// Get the initial context
Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,
"com.ibm.websphere.naming.WsnInitialContextFactory");
env.put(Context.PROVIDER_URL, "corbaloc::app1:9811,:app2:9812");
Context initialContext = new InitialContext(env);
// Look up the home interface using the JNDI name
try {
java.lang.Object ejbHome =
initialContext.lookup("cell/clusters/EJBcluster/BeenThere");

This is fault tolerant, so if one process goes down, another can be used as the
naming provider, and the cluster can be accessed via the appropriate cell-based
path in the lookup.

Hi WAS,

  Ryman explain the way to do.  If you want more information I suggest to review the next chapters in redbook

Thank you Gabriel and Ryman, I really appreciate this
