Error description

When a deployment manager is migrated from V6.0 or V6.1 to
V7.0, and it still manages V6.0 or V6.1 nodes, a transformation
(sib-resources.xsl) fails to strip the V7.0 WebSphere MQ
resource adapter from the resources.xml when the V7.0 deployment
manager synchronizes with the V6 node.  Because the V7.0
WebSphere MQ resource adapter does not exist in V6.0 or V6.1, a
ClassNotFoundException is thrown during the startup of the
application server:

java.lang.ClassNotFoundException:
com.ibm.mq.connector.ResourceAdapterImpl

The problem does not occur in V7.0; it is introduced in
V7.0.0.1.

Here is the stack trace of the exception:

Local fix

Migrating the V6 nodes in the cell to V7.0 will resolve the
problem.

****************************************************************
This issue only affects users with fix pack 7.0.0.1 applied to
the deployment manager of the cell.

The issue is due to some V7.0 configuration information being
incorrectly synchronized to the older version nodes.
The configuration information relates to the WebSphere MQ
resource adapter, available only in WebSphere Application
Server Version 7.0.

An example of the error seen in the JVM logs is as follows:
[11/15/08 21:49:21:360 EST] 0000000a RAWrapperImpl E
J2CA0043E: An Exception occurred while trying to instantiate a
ResourceAdapter java bean instance for the installed
ResourceAdapter defined by key
cells/artaccCell01/resources.xml#J2CResource
Adapter_1226802925350.  The exception is:
java.security.PrivilegedActionException:
java.lang.ClassNotFoundException:
com.ibm.mq.connector.ResourceAdapterImpl

Problem conclusion

The fix for this APAR prevents the invalid configuration
information from being synchronized to Version 6.1 and earlier
nodes.

The fix is currently targeted for fix pack 7.0.0.3.
