Abstract:  In a mixed cell environment where a node is at V6.0.1.x and the Deployment Manager is at V6.0.2, errors may occur when using Relationship Manager.

Description/symptom of problem:  
JR25444 resolves the following problem:

ERROR DESCRIPTION:                                              
In the mixed cell environment if user upgraded one node to 602, 
and one stayed as 601, then RelManager doesn't work because we  
changed the RelationshipQuery model in 6012 (and 602). So       
to resolve the issue the ifix for this APAR needs to be         
installed on top of 601 nodes.

PROBLEM SUMMARY

USERS AFFECTED:
WebSphere Process Server 6.0.1.x Users

PROBLEM DESCRIPTION:
In a mixed cell environment where a
node is at V6.0.1.x and the Deployment
Manager is at V6.0.2, errors may occur
when using Relationship Manager.

RECOMMENDATION:
None

The RelationshipQuery model changed between versions v6.0.1.2
and v6.0.2, and as a result, problems can occur in the
RelationShip Service after the Deployment Manager has been
upgraded to V6.0.2 while a node stays at v6.0.1.x.

For example, the SystemOut.log may show the following message
after a RelationShip query operation:

CWMAM0009W: There was a null response from the Relationship
Services MBean. Please execute another query, or query using
a different MBean.

Further queries may result in null pointer exceptions.

PROBLEM CONCLUSION:                                             
Install the ifix on top of 601 nodes to solve the problem.
