PROBLEM SUMMARY

USERS AFFECTED:
All users of WebSphere Extended Deployment
using the On Demand Router.

PROBLEM DESCRIPTION:
After an application edition rollout,
Http requests are returned with Http
response code of 503.

RECOMMENDATION:
None

When an application edition is being rolled out, existing Http
session requests need to finish up on the old edition. After
this was done, there were additional requests being sent to
the older edition, but needed to be routed to the new edition.
This resulted in a 503 Http response code, because the
application server of the older edition was not in a started
state.

PROBLEM CONCLUSION:                                             
The code was fixed to route requests properly and the fix was   
made available for the 6.1 release. The fix will be included    
in Service Pack 6.1.0.3 for WebSphere Extended Deployment.

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 6.1.0.1-WS-WXD-IFPK66889.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 (6.1.0.1-WS-WXD-IFPK66889.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.
