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.

com.ibm.websphere.wim.exception.WIMApplicationException:
CWWIM4506E Virtual member manager failed to search the entity

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
Level (Fix Pack) 6.1.0.33 of WebSphere Application Server V6.1.
