Last updated on AUGUST 16, 2017

Applies to:

Oracle WebLogic Server - Version 12.1.3.0.0 to 12.1.3.0.0 [Release 12c]
Information in this document applies to any platform.

Symptoms

On : 12.1.3.0.0 version, General component

Using IIOP to remotely connect to EJB's running in a weblogic cluster does not work.

If one of the cluster nodes stops the client does not fail over to the other node but throws an exception.

javax.naming.NamingException: Unhandled exception in lookup [Root exception is org.omg.CORBA.COMM_FAILURE: Connection refused: connect vmcid: 0x0 minor code: 0 completed: No]

(...)
Caused by: java.net.ConnectException: Connection refused: connect

When using T3 as a protocol this works without exceptions.
