Abstract:  Requests are misclassified for applications installed on a generic server cluster.

Description/symptom of problem:  
PM23486 resolves the following problem:

ERROR DESCRIPTION:                                              
When multiple generic server cluster routing policies are       
configured using different virtual hosts, which contain matching
URI patterns, the routing rule that is matched first will be    
used regardless of the virtual host.                            

LOCAL FIX:                                                      
N/A                                                             

PROBLEM SUMMARY

USERS AFFECTED:
 All users of WebSphere Extended Deployment
who are using the on demand router

PROBLEM DESCRIPTION:
Requests are misclassified for
applications installed on a generic
server cluster.

RECOMMENDATION:
None

Requests that are intended for one application on a generic
server cluster are matched to the incorrect web module.

PROBLEM CONCLUSION:                                             
The code has been updated to correctly classify requests based  
on the correct web module and application.                      
                                                                
This fix will be included in the next available fix pack for    
WebSphere Virtual Enterprise.                                   


Directions to apply fix:  
Install Fix to:
__ Application Server Nodes
__ Deployment Manager Nodes
_x_ Both

NOTE:
The user must have Administrative rights in Windows, or be the Actual Root User in a UNIX environments. Also, you should be logged in with the same authority level when unpacking a fix, fix pack or refresh pack.

DOWNLOAD THE UPDATE INSTALLER TOOL IN ORDER TO INSTALL A FIX.
The Fix Installer can be downloaded from the following link:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg21205991

The Update Installer for V5.0 does not have a maintenance directory. It uses fixpacks and fixes as the location of the unpacked files.

Customers must be at V6.1.0.17 or newer of the Update Installer.?This can be checked by reviewing the level of the Update Installer in file <was_root>/updateinstaller/version.txt.

1) Copy 6.1.1.2-WS-WXD-IFPM23486.pak file directly to the maintenance directory

2) Shutdown WebSphere
Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere instance that maintenance is being applied to.

3) Launch Update Installer

4) Enter the installation location of the WebSphere product you want to update.

5) Select the "Install maintenance package" operation.

6) Enter the file name of the maintenance package to install (6.1.1.2-WS-WXD-IFPM23486.pak file which was copied in the maintenance directory).  The V5.0 and V5.1 fix packs and fixes are unpacked as .jar files and should be unpacked into fixpacks or fixes directory.

7) Install the maintenance package.

8) Restart WebSphere

Directions to remove fix:  
NOTE:  The user must have Administrative rights in Windows, or be the Actual Root User in a UNIX environments.

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) Shutdown WebSphere
Manually execute setupCmdLine.bat in Windows or . ./setupCmdLine.sh in Unix from the WebSphere instance that uninstall is being run against.

2) Start Update Installer

3) Enter the installation location of the WebSphere product you want to remove the fix.

4) Select  "Uninstall maintenance package" operation.

5) Enter the file name of the maintenance package to uninstall (6.1.1.2-WS-WXD-IFPM23486.pak).

6) UnInstall maintenance package.

7) Restart WebSphere

Directions to re-apply fix:  
1) Shutdown WebSphere

2) Follow the Fix instructions to apply the fix.

3) Restart WebSphere

Additional Information:  PM23486 and PM23436 should both be installed.
