Symptoms
When doing JNDI lookups from a remote client using the provider url(opmn:ormi://logicalhostname:18510:oc4j/app) fails with error "Error obtaining server list form OPMN on host..."
If, the provider url
opmn:ormi://hostname:18510:oc4j/appis used, everything is fine.
Since the machine is part of a cluster it is important to be able to use the logical host name in
the JNDI lookup provider url. Logical hostname is actually a Veritas Cluster Server service
group. This group's hostname is used by the RMI/JNDI clients. The logical hostname has its own ip
address that differs from the ip of the actual host running the AS instances.
Using a logical hostname is desirable since the cluster server might fail over to another machine
and the clients should not have to know about the hostnames of the hosts that are part of the
cluster.
