PROBLEM SUMMARY

USERS AFFECTED:
All IBM WebSphere Application Server
version 6.0.2 and 6.1 users of the
proxy/On-Demand Router (ODR) server

PROBLEM DESCRIPTION:
On Demand Configuration (ODC) tree is
not properly updated  when
applications stop or are uninstalled
from an application server

RECOMMENDATION:
None

Proxy server/ODR may not correctly recognize that an
application is down or uninstalled, and will incorrectly route
requests to an application server which is not currently
running the requested application.

PROBLEM CONCLUSION:                                             
The On Demand Configuration component will be corrected to      
report and respond to application stop/uninstalled messages     
correctly to ensure the proxy server/ODR has the correct        
application status information so it does not misroute          
requests.  Interim fix PK52945 will be made available and the   
fix will be included in fixpacks 6.0.2.25 and 6.1.0.15.

NOTE:
If you have not previously applied PK51304, you will need to bring your entire cell down when applying this ifix, and then bring it back up only after all nodes have been patched.

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 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 PK52945.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 (PK52945.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

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 (PK52945.pak).
