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


Too many partitions

As a general rule, applications should use as few partitions possible. The partitioning facility can scale to a very large number of partitions, but more partitions equates to more memory and additional management overhead. The Java™ Virtual Machines (JVMs) hosting the highly available (HA) manager coordinators must have adequate memory to manage their partitions. It is possible to tell the HA manager to use more than one coordinator to manage its partitions. If the applications in a core group use many partitions (>1,000), then the HA manager should be configured to use more coordinators. The actual number that a single coordinator can manage depends on the amount of available memory in the JVM and the number of partitions per coordinator. Partitions are uniformly distributed over the available coordinator JVMs using a hash scheme.
