ERROR DESCRIPTION:                                              
This is a cumulative fix for various problems in the dynamic    
workload management component of WebSphere Extended Deployment  
6.0.2.  Problems in this component can cause the On Demand      
Router to route incorrectly to back-end application servers,    
such as failure to route or failure to preserve session         
affinity.

Includes fixes for On Demand Router problems including failure  
to route and failure to keep session affinity.  This            
supercedes APAR PK44903.  This fix is being released for        
WebSphere Extended Deployment V6.0.2 over Network Deployment    
V6.0.2 as well as WebSphere Extended Deployment V6.0.2 over     
Network Deployment V6.1.  The fix for this APAR is currently

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 V6.0.2.2 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 6.0.2.0-WS-XD-IFPK47052.pak or 6.0.2.0-WS-WXD-IFPK47052.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 (PKxxxxx.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.

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 (6.0.2.0-WS-XD-IFPK47052.pak or 6.0.2.0-WS-WXD-IFPK47052.pak).
