PM47660 resolves the following problem:

ERROR DESCRIPTION:                                              
Visualization data service is consuming a large amount of heap  
and contributing to a high cpu condition, either directly or    
indirectly through increased garbage collection.                
.                                                               
This ifix will turn off stat collection when no one is logged   
into the admin console AND visdataservice logging is disabled.

PROBLEM SUMMARY

USERS AFFECTED:
 All users of WebSphere Virtual Enterprise.

PROBLEM DESCRIPTION:
The deployment manager (dmgr) is
using high levels of CPU.

RECOMMENDATION:
None

Internal caches used for reporting on the admin console were
not shutting down when users logged off the admin console.
This resulted in unnecessary CPU usage.

PROBLEM CONCLUSION:                                             
The code was updated to ensure caches are turned off when not   
needed.                                                         
                                                                
This fix will be included in the next available fix pack for    
WebSphere Virtual Enterprise.
