Abstract: Errors occur when PM01122 is installed in environments containing Virtual Enterprise Version 6.1.1 and eXtreme Scale Version 6.1.0.5.

PM09462 resolves the following problem:

ERROR DESCRIPTION:                                              
Modify the maintenance.xml file for PM01122 so the fix can be installed in environments in which WebSphere Virtual Enterprise Version 6.1.1 
and WebSphere eXtreme Scale Version 6.1.0.5 are installed. 

LOCAL FIX:                                                      
n/a                                                             

PROBLEM SUMMARY
In certain cases, many subjects are created on the bulletin board per servlet in a webAppModule.

USERS AFFECTED:
All users of WebSphere Virtual Enterprise Version 6.1.1.

PROBLEM DESCRIPTION:
The creation of subjects on the bulletin board per servlet and per webAppModule could cause a lot of posts and overwhelm the
bulletin board, which would cause the Java virtual machine (JVM) to receive an out of memory error. This problem is not
common and can happen only in very limited cases.

RECOMMENDATION:
None

PROBLEM CONCLUSION:                                             
A custom property was created to prevent the path where subject per servlet and per webAppModule are created. 
Set the disableWebAppModuleSubStats custom property to true at the cell level.                                                     
                                                                
This fix is identical to APAR PM01122, except it can be installed in environments in which WebSphere Virtual Enterprise Version 6.1.1
and WebSphere eXtreme Scale Version 6.1.0.5 are running.

1) Copy PM09462.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 (PM09462.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.
