Error description

Error Description:

Running the "createCluster" administrative command with the
option to convert an existing server to the new cluster, in
a particular environment, generates the following exception:
java.lang.NullPointerException
at
com.ibm.ws.management.configservice.ConfigServiceImpl.setAttribu
tes(ConfigServiceImpl.java:1116)

com.ibm.events.admintask.CeiClusterAdminTaskExt.executeStep(CeiC

at
com.ibm.websphere.management.cmdframework.provider.AbstractTaskC
ommand.execute(AbstractTaskCommand.java:802)
...

The particular environment where the exception appears can be
obtained through the following steps:

1. Create an application server profile containing a standalone
server
2. Install CEI application on the standalone profile.
3. Create a deployment manager profile.
4. Federate the server by running the addNode command.
5. Convert the server to a cluster with the command:
"$AdminTask createCluster { -clusterConfig { -clusterName
<cluster_name> }  -convertServer { -serverNode <server_node>
-serverName <server_name> }}"

Problem summary

****************************************************************
* USERS AFFECTED:  All users of IBM WebSphere Application      *
*                  Server Network Deployment edition V7.0 and  *
*                  V8.0 who federate a standalone server and   *
*                  then migrate it to a cluster                *
****************************************************************
* PROBLEM DESCRIPTION: NullPointerException thrown when        *
*                      converting a server to a cluster if     *
*                      Common Event Infrastructure (CEI)       *
*                      application is installed                *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
When a WebSphere Application Server node containing a
standalone server with a Common Event Infrastructure (CEI)
application installed is federated, the scope of the bus used
by CEI is updated, but its name is kept unchanged.
In the same manner, when the server is migrated to a cluster
using the administrative command "$AdminTask createCluster"
with the "convertServer" option, the bus used by CEI is
identified and its scope is updated, but its name remains
unchanged.
If the bus used by CEI is not correctly identified by the
migration process, the NullPointerException exception can
occur with a stack as follows:
java.lang.NullPointerException
at
com.ibm.ws.management.configservice.ConfigServiceImpl.setAttribu
tes(ConfigServiceImpl.java:1116)
at
com.ibm.events.admintask.CeiClusterAdminTaskExt.executeStep(CeiC
lusterAdminTaskExt.java:202)
at
com.ibm.websphere.management.cmdframework.provider.AbstractTaskC
ommand.executeReal(AbstractTaskCommand.java:839)
at
com.ibm.websphere.management.cmdframework.provider.AbstractTaskC
ommand.execute(AbstractTaskCommand.java:802)
...
Due to this exception the migration process cannot be
completed.

Problem conclusion

To prevent the exception, the algorithm for the identification
of the CEI bus was enhanced to support the case when a CEI
application was initially installed on the standalone server.

The fix for this APAR is currently targeted for inclusion in
fix packs 7.0.0.21 and 8.0.0.2. Please refer to the
