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)Create a <WASHOME>/Fix directory if one does not already exist

5) Run the jar file with the following command answering questions/prompts as they appear:
   java -jar <jarfile name> -backupJar <WASHOME>/Fix/<jar file name>_backup.jar

6) Restart WebSphere

7) 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 directory.
   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>/Fix).

2) Shutdown WebSphere

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

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.
