Abstract:  PQ65964 broke 4.0 coexistence with 3.5

Description/symptom of problem:  The WAS 4.0 plugins were written so they could coexist with the WAS 3.5 plugins - allowing customers to run a single web server with both the 3.5 and 4.0 plugins
loaded.  PQ65964 for 3.5 disrupted this coexistence for customers running 4.0.5 or higher.   When this happens, all the requests for one version of the plugins will fail. Removing PQ65964 from the 3.5 install, or moving the 4.0 install back to 4.0.4 or below will make the plugins start working again.

This fix is a replacement for PQ65964 which provides the same functionality without breaking 3.5/4.0 coexistence.

Due to the nature of the fix, it must be applied to both the 
web server and application server installations that make up a
WebSphere system.  For instance, if I have web server X, whose
plugins are configured to send requests to application server
installations A, B and C, then installing this fix on X requires
that the fix also be installed on A, B and C.  Failure to apply
the fix to both the application server and web server installations
will probably result in a system that can't serve requests.














Directions to apply fix:  For each web server plugin installation, and the related application server installations:

1) Shut down the web servers and/or application servers on this machine.

  2) AIX only: As root, run "slibclean". 

  3) Make a backup copy of the shared libraries that reside
     in the WAS_ROOT/bin directory.

  4) Unpack the fix tar file, and copy the shared libraries into the
     WAS_ROOT/bin directory.

  5) Start the web server and application servers back up.















Directions to remove fix:  1) Shut down the web server and/or application servers on this machine.

  2) AIX only: As root, run "slibclean". 

  4) Copy the shared libraries that were backed up in the 
     installation step to the WAS_ROOT/bin directory.

  5) Start the web server and application servers back up.















Directions to re-apply fix:  
1) Follow the instructions for removing a fix.
2) Follow the instructions for applying a fix.
