Deprecated feature: The partitioning facility (WPF) feature is deprecated. You can configure partitioning with WebSphere eXtreme Scale.


Balancing the partitions


About this task

You can implement any balancing algorithm through the Java™ Management Extensions (JMX) interfaces provided. In addition, the wpfadmin command provides two basic options, a simple balancer and one that balances upon the certain performance monitoring attributes (used only when performance monitoring is enabled). For this example, you can simply balance the partitions in a round-robin format using the basic function.

Issue the command wpfadmin balance, and the output should show...

Sometimes, the partitions are not totally balanced. This is working as designed. Partition balancing cannot guarantee its result. Users can use policies to make sure partitions are distributed evenly.
