This document describes a very specific scenario where configuration for instances in a FMW Console was mixed up between two weblogic domains deployed in the same server.


Symptoms

When starting a webtier instance from FMW console it was returning error and failed to start.
The Webtier could be started from command line using opmnctl startall without any problem.

In the FMW Console the error reported was:

"Error flushing write connection to OPMN. The remote OPMN server is probably not running or the OPMN mbean is not properly configured. See the adminserver log for more details."


and in the log file of the AdminServer where FMW console ran the following error was logged:

<Error> <oracle.as.management.mbeans.opmn> <BEA-000000> <OPMN mbeanstart failed with the following exception
