CWSIV0775W, CWSIT0088E and CWSIT0103E errors are thrown and application is not able to find running Messaging Engine even through the same Messaging Engine is running in the cluster

Technote (troubleshooting)


Application is not able to find the running WebSphere Application Server (WAS) Messaging Engine (ME), even though the requested ME is up and running.


You see the following errors in the SystemOut.log:

The Service Integration Bus (SIB) relies on the Work Load Manager (WLM) to locate messaging engines (ME). When an application makes a connection request, the WLM tries to find the ME. If the ME is running on a server that is not part of the local core group, and there is no bridge between the local core group and the one where the desired ME is running, then the WLM will not be able to find the ME, even though it is running.

This equally applies if client and server are in different cells.

Resolving the problem

Add all servers to the same core group, or configure a bridge between the core groups if the servers need to be members of a different core group.

The following articles may be useful in planning your core group configuration.
