PK02090 resolves the following problem:

ERROR DESCRIPTION:
PMI doesn't register a WebModule correctly once application is stopped. The following message is seen in SystemOut.log:

1cf938ba TraceNLS u No message text associated with key DataAccessWrapper.getLong.exception.java.lang.NullPointerException in bundle com.ibm.ws.performance.tuning.properties.perftuning

java.lang.NullPointerException

PROBLEM SUMMARY:

USERS AFFECTED:
WebSphere Application Server 5.0.2 and 5.1 Runtime Performance Advisor users.

PROBLEM DESCRIPTION:
Performance Advisors are available and preform correctly. The Application Server is then started successfully. However, when an application is stopped and started immediately, an exception is thrown every 10 seconds.

RECOMMENDATION:
When an Application is restarted immediately after stopping it, the Runtime Performance Advisor(RPA) does not detect the Application restart. Subsequently RPA throws an exception every 10 secs, when getting the PMI statistics for the Application.

PROBLEM CONCLUSION:
The Runtime Performance Advisor code has been modified to detect the restart of Applications.

The fix for this APAR is currently targeted for inclusion in fixpack 5.02.12 and 5.1.1.5.
