CMVC Defect:  PQ76488

Byte size of APAR:  96,888

PROBLEM SUMMARY:
In a deployed environment where there are one or more WebSphere application 
servers and WorkLoadManager is enabled, if a network adapter becomes 
disconnected or has a hardware failure, opCenter detects that all application 
servers on that node are unavailable.  However, even when the network adapter 
is reconnected/replaced, OpCenter fails to detect and change the state of 
those application servers to available.  The end result is PMI metric data 
is not collected and submitted to WorkLoad Manager.   This will cause 
inaccurate work load balancing among the application servers in the 
deployed environment. 

PROBLEM CONCLUSION: 
In order to ensure that OpCenter correctly updates the states of application 
servers on a node that has experienced a disconnected network adapter, 
interim fix PQ74688 should be applied.

Directions to apply fix:  

1) Create temporary "Fix" directory to store the jar file:
             UNIX: /tmp/WebSphere/Fix
          Windows: c:\temp\WebSphere\Fix

2) Copy jar file to the directory

3) Shutdown WebSphere

4) Follow the Fix installation instructions that are packaged with the Update Installer on how to install the Fix.

5) Restart WebSphere

Directions to remove fix:  

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.
