PROBLEM SUMMARY

USERS AFFECTED:
 Websphere Process Server versions 6.0.2.x,
6.1.0.x, and 6.1.2.x.

PROBLEM DESCRIPTION:
A memory leak may occur in Service
Component Architecture( SCA) code
when the targetSignificance is null.

RECOMMENDATION:
None

The references to configuration session objects used in SCA
are not released after usage. For each session an anonymous
workspace is created in wstemp directory. This results in
memory and disk shortage problems.

PROBLEM CONCLUSION:                                             
Installing this interim fix resolves the above memory leak      
issue in SCA.

1) Copy the pak file to the directory maintenance in the UpdateInstaller directory

2) Shutdown WebSphere Process Server. It is important that you perform a controlled and complete shutdown of the server to ensure that all transactions have completed, before installing the fix.

3) Run the UpdateInstaller and follow the prompts.

4) Restart WebSphere Process Server.

Directions to remove fix:  
NOTE:  FIXES MUST BE REMOVED IN THE REVERSE ORDER IN WHICH THEY WERE APPLIED.  DO NOT REMOVE A FIX UNLESS  ALL FIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED.  YOU MAY REAPPLY ANY REMOVED FIX.

Example:  If your system has fix1, fix2, and fix3 applied in that order and fix2 is to be removed, fix3 must be removed first, then fix2 may be removed

1) Shutdown WebSphere Process Server. It is important that you perform a controlled and complete shutdown of the server to ensure that all transactions have completed, before installing the fix.

2) Follow the Fix instructions that are packaged with the Fix Installer on how to uninstall and reinstall the Fix.

3) Restart WebSphere Process Server.

Directions to re-apply fix:  
1) Shutdown WebSphere. It is important that you perform a controlled and complete shutdown of the server to ensure that all transactions have completed, before installing the fix.

2) Run the UpdateInstaller and follow the instructions. The Update Installer can be downloaded from the following link:
