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

Statistics aggregation interval

The PMI aggregator aggregates and sorts the PMI statistics in intervals. This interval is called the statistics aggregation interval.

Use wpfAdmin.bat|wpfadmin setStatisticsInterval INTERVAL--id PMI_SUBSCRIPTION_ID to set the partition count for one PMI subscription. You can also use Java™ code, jacl script, or jython script to get the MBean instance, and change the statistics aggregation interval through the MBean.

  1. Run wpfadmin setStatisticsInterval 10000 --id 1 to change the statistics interval to 10 seconds.

  2. Run wpfadmin setPartitionCount 9 --id 1 to change the partition count to 9.

  3. Keep a record of the current time, then retrieve the statistics by running wpfadmin getResponseTime --id 1 until you see 9 partitions in the output. Calculate how many seconds have passed. Notice that it is much quicker to show 9 partitions than to show 8 partitions.
