Abstract

LIC-PERF ISOLATE TASKS ARE TOO DISRUPTIVE TO OTHER TASKS
RUNNING.

Error Description

When a dlpar memory remove occurs it is necessary to make      
repetitive calls to the hypervisor so they can verify that no  
usage of the memory is occurring.  The code starts tasks to do  
these calls, and these tasks can be disruptive to other tasks  
that are running on different threads on the same processors.  

Problem Summary

When a dlpar memory remove occurs it is necessary to make      
repetitive calls to the hypervisor so they can verify that no  
usage of the memory is occurring.  The code starts tasks to do  
these calls, and these tasks can be disruptive to other tasks  
that are running on different threads on the same processors.  

Problem Conclusion

To minimize the disruption to other tasks running in the system
we will have the dlpar memory remove tasks run in their own    
workload capping group.
