Error description

  • Performance issues when using federated repositories with RACF
    registry
    
    When starting Websphere Application Server using federated
    repositories, the server takes a long time to start up, if it's
    configured to use the RACF registry.  It especially takes long
    if there are lots of users in the RACF registry.
    
    You may notice the below exception during the server startup
    which may prevent the server to start.

    ****************************************************************
    NullPointerException and performance issues are seen during
    server startup while using Federated repositories with
    RACF.When starting Websphere Application Server using
    federated repositories, the server takes a long time to start
    up, if it's configured to use the RACF registry.  It especially
    takes long if there are lots of users in the RACF registry.
    You may notice the below exception during the server startup
    which may prevent the server to start. The Exception thrown as:-
    com.ibm.websphere.wim.exception.WIMApplicationException:
    CWWIM4506E Virtual member manager failed to search the entity
    : 'java.lang.NullPointerException'.
    

Problem conclusion

  • Code changes made to correct the NullPointerException as well
    to use the correct API for user validation during login, which
    fixes performance issue in server startup.
    
    APAR PM11190 is currently targeted for inclusion in Service
