Deprecated feature: The partitioning facility (WPF) feature is deprecated. You can configure partitioning with WebSphere eXtreme Scale.
Partitioning facility PMI statistics parameters
As mentioned previously, a partitioning facility statistic has several parameters. You may have used them in the subscribeWPFPMI parameter.
- Application name and session EJB
Partitions are grouped by the application name and the session Enterprise JavaBeans (EJB) name. When subscribing the partitioning facility PMI statistics, users have to specify the application name and the session EJB name.
- Statistics type
There are two types of partition statistics users are interested in: transaction count or response time. Transaction count tracks the number of transactions in a certain period. Response time tracks the total response time of all transactions over a certain period. The partitioning facility (WPF) has its own WPF PMI module, called wpfModule, which can be enabled to track these two statistics. There is only one TimeStatistics in this module, since transaction count can also be tracked by TimeStatistics objects.
- Statistics range
There are two types of statistics ranges: cumulative statistics or active statistics. Cumulative statistics track statistics from transaction one in a partition. Active statistics track statistics over the recent period. For example, you can track how many transactions occurred in the latest 15 seconds.
- Partition count
You can set the number of partitions.
- Statistics aggregation interval
The PMI aggregator aggregates and sorts the PMI statistics in intervals. This interval is called the statistics aggregation interval.
- WPF PMI aggregator policy
The PMI aggregator is a highly available (HA) group member. You can configure the HA group parameters, such as which server the aggregator is running, or whether the aggregator runs in preferred servers.
