PROBLEM SUMMARY

USERS AFFECTED:
 All users of WebSphere Virtual Enterprise
v6.1.1.x.

PROBLEM DESCRIPTION:
The On-Demand Router (ODR) does not
properly route requests for modules
that have been mapped to multiple
cluster targets.

RECOMMENDATION:
None

When application modules have been mapped to multiple clusters
or multiple non-clustered application servers, the On-Demand
Configuration (ODC) component does not correctly represent all
module target mappings. This results in ODRs not properly
routing requests destined for these modules and can cause the
return of erroneous 503 error codes.

PROBLEM CONCLUSION:                                             
The ODC component has been altered to correctly process and     
represent all target mappings for all application modules,      
specifically modules that have been mapped to multiple targets. 
                                                                
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 6.1.1.0-WS-WXD-IFPM46463.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 (6.1.1.0-WS-WXD-IFPM46463.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 (6.1.1.0-WS-WXD-IFPM46463.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
