PROBLEM SUMMARY

USERS AFFECTED:
 All users of Websphere Virtual Enterprise
Version 6.1.0.x

PROBLEM DESCRIPTION:
Cell affinity is incorrectly
preserved to servers outside of the
scope of an application's routing
rules.

RECOMMENDATION:
None

When attempting to preserve affinity, the on demand router
(ODR) might route to a server that is not defined in the
routing rules for the application. As a result, the requests
might be sent to the wrong server.

PROBLEM CONCLUSION:                                             
The range of target servers are now limited to the set          
encompassed by the routing rules for the application.

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 PK98103.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 (PK98103.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.
