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

Scalability considerations

For customers who plan to have high workload environments, it is important to plan how the cluster will operate in normal conditions and under failure conditions. This section serves as a reminder to administrators and programmers to avoid common scenarios that degrade cluster performance. Each application solution is different, but these guidelines should provide some general advice to ensure the application can achieve and sustain a high performance implementation.

The highly available (HA) manager monitors many cluster wide resources. In general, this takes a certain amount of performance. If the cluster members are paging or otherwise engaged such that the HA manager functionality cannot operate effectively, HA managed events will begin to occur to account for perceived cluster member anomalies. IBM recommends that the application servers not be under a large load in normal cases to better handle spikes at times when challenges arise. In addition, reducing virtual memory paging as much as possible will result in a more reliable cluster operational environment.
