Abstract: DynaCache has problems switching between WebModules/ContextRoot


Description/symptom of problem:
With servlet caching enabled WAS 4.02 has problems with servlet
s and JSPs:  JSPs cannot be executed, an exception is thrown.
WAS mishandles context roots when a servlet is included across
webapps. Request attributes with complex objects are incorrect after an
include.                                                       


Directions to apply efix:

1) Create temporary "eFix" directory to store the zip/tar file:

             AIX: /tmp/WebSphere/eFix

   Solaris/Linux: /tmp/WebSphere/eFix

         Windows: c:\temp\WebSphere\eFix


2) Copy zip/tar file to the directory

3) Unzip/untar the file

4) Shutdown WebSphere

5) Run the jar file with the following command answering questions/prompts as they appear:

   java -jar <jarfile name> -TargetDir <your WAS_HOME directory, e.g. c:\WebSphere\AppServer for example>

6) Restart WebSphere

7) The temp directory may be removed but the zip/tar file should be saved.  Do not remove
   any files created and stored in the <WASHOME>/WebSphere/AppServer/eFix/<APAR#> directories.
   These files are required if an efix is to be removed.




Directions to remove an efix:

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/<APAR#>).

2) Shutdown WebSphere

3) Run the backup jar file with the following command:

   java -jar <backup_APAR#>

4) Restart WebSphere




Directions to re-apply an efix:

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.




Trouble shooting
--------------------------------------------------------------------------------------
o  If an efix complains about the container type and you are sure it should match, contact
   WebSphere L2 Support for assistance with the -SkipContainerCheck option to the efix jar.
