Abstract:  Distributed transaction may complete inconsistently.

Description/symptom of problem:  
When running a distributed transaction across two servers with
interop mode active, the superior server failed. A request
from the superior to the subordinate server was inflight at
the time.When the superior was brought back up, it was
discovered that the transaction on the superior had
rolled-back, while the transaction on the subordinate had
committed.



Directions to apply fix:  

1) Create temporary "fix" directory to store the jar file:
                  AIX: /tmp/WebSphere/fix
                  Solaris/Linux: /tmp/WebSphere/fix
                  Windows: c:\temp\WebSphere\fix

2) Copy jar file to the directory

3) 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.

4) Run the jar file with the following command answering questions/prompts as they appear:
   java -jar PQ98484_Fix.jar

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>/WebSphere/AppServer/fix/<fix> 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 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, fix2 removed, and fix3 re-applied.

1) Change directory to the fix location (<WASHOME>/WebSphere/AppServer/fix/<fix#>).

2) 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.

3) Run the backup jar file with the following command:
   java -jar PQ98484_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.
