CMVC Defect:  PQ74639

Byte size of APAR:  1077013

Date: 12/23/03

Abstract:  Hanging or Lost Threads or wait on writeLock()

Description/symptom of problem:  ORB worker threads stay around and not go away. Sometimes they seem to hang.





Directions to apply fix:  

1) Create temporary "Fix" directory to store the jar file:
            UNIX: /tmp/WebSphere/Fix
         Windows: c:\temp\WebSphere\Fix

2) Copy jar file to the directory

3) Shutdown WebSphere

4) Run the jar file with the following command answering questions/prompts as they appear:
   java -jar <jar file name>

5) Restart WebSphere

6) The temp directory may be removed but the jar file should be saved.  Do not remove 
   any files created and stored in the <WASHOME>/Fix/PQ##### directories.
   These files are required if a Fix is to be removed.





Directions to remove fix:  

NOTE:  FIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED.  DO NOT REMOVE A FIX UNLESS
       ALL FIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED.  YOU MAY RE-APPLY 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, Fix2 removed, and Fix3 re-applied.


1) Change directory to the Fix location (<WASHOME>/Fix/PQ#####).

2) Shutdown WebSphere

3) Run the backup jar file with the following command:
   java -jar PQ#####_Fix_backup.jar

4) Restart WebSphere





Directions to re-apply fix:  

Follow the instructions for applying a Fix.  If the backup files still exist (from the 
previous Fix application), you will be prompted to overwrite.  Answer "yes" at the overwrite 
prompts.
