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

    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
