Abstract:  Inter-op problem found when passing embedded valueTypes between WAS releases

Description/symptom of problem:  

User may experience org.omg.CORBA.MARSHAL exceptions. Note, that these exceptions are sometimes
masked by other exceptions in WAS or user application code. And errors are sometimes hard to 
identify.

This is why we strongly recommended thta e-fixes are applied as soon as possible to avoid future
inter-op issues. Also, user may experience this problem even after efixes have been applied, if
user has saved off his IORs. If this is the case, user needs to re-export those IORs for the efixes
to take their full effect. 


Known affected combinations
WAS35x ==> WAS356+ or WAS403+ or higher releases
WAS40x ==> WAS356+ or WAS403+ or higher releases





Directions to apply fix:  

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

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 <jarfile 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>/WebSphere/AppServer/efix/<efix> directories.
   These files are required if an efix is to be removed.





Directions to remove fix:  

NOTE:  EFIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED.  DO NOT REMOVE AN EFIX UNLESS
       ALL EFIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED.  YOU MAY REAPPLY ANY REMOVED EFIX.

Example:  If your system has efix1, efix2, and efix3 applied in that order and efix2 is to be
          removed, efix3 must be removed first, efix2 removed, and efix3 re-applied.


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

2) Shutdown WebSphere

3) Run the backup jar file with the following command:
   java -jar <backup_efix#>

4) Restart WebSphere





Directions to re-apply fix:  

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