Abstract:  The application placement controller creates runtime tasks, but no servers are started.

Description/symptom of problem:  
PM18596 resolves the following problem:

ERROR DESCRIPTION:                                              
When dynamic clusters are in supervised mode, a deadlock might  
occur between runtime tasks as the application placement        
controller administers changes.                                 

LOCAL FIX:                                                      
N/A                                                             

PROBLEM SUMMARY

USERS AFFECTED:
 All users of WebSphere Virtual Enterprise
Version 6.1.0.x who are using the
application placement controller

PROBLEM DESCRIPTION:
The application placement controller
creates runtime tasks, but no servers
are started.

RECOMMENDATION:
None

This problem occurs only for dynamic clusters that are in
supervised mode. If multiple dynamic clusters are in
supervised mode, runtime tasks are created and a deadlock
occurs between the two runtime tasks. Each runtime task
depends on the other one completing before that particular
task can be administered.

PROBLEM CONCLUSION:                                             
This cumulative fix for the application placement controller    
will no longer create a deadlock situation between runtime      
task for dynamic clusters that are in supervised mode.          
                                                                
This fix will be included in the next available fix pack for    
WebSphere Virtual Enterprise.                                   


Directions to apply fix:  
Install Fix to:
NOTE: Developers -  Place and X next to the proper installation method and remove this note
__ Application Server Nodes
__ Deployment Manager Nodes
_x_ Both

NOTE:
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 Fix Installer can be downloaded from the following link:
http://www.ibm.com/support/docview.wss?rs=180&uid=swg21205991

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 PM18596.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 (PM18596.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

Directions to remove fix:  
NOTE:  The user must have Administrative rights in Windows, or be the Actual Root User in a UNIX environments.

NOTE:  FIXES MUST BE REMOVED IN THE ORDER THEY WERE APPLIED.
DO NOT REMOVE A FIX UNLESS
ALL FIXES APPLIED AFTER IT HAVE FIRST BEEN REMOVED.
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 (PM18596.pak).

6) UnInstall maintenance package.

7) Restart WebSphere

Directions to re-apply fix:  
1) Shutdown WebSphere

2) Follow the Fix instructions to apply the fix.

3) Restart WebSphere
