Deprecated feature: The partitioning facility (WPF) feature is deprecated. You can configure partitioning with WebSphere eXtreme Scale.
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.
Both transaction count and response time will be displayed when you retrieve the statistics. This statistics type is used for sorting purpose. When statistics type is set to TransactionCount the statistics are sorted by transaction counts, and when set to ResponseTime the statistics are sorted by response time.
Use one of the following commands to set the statistics type for one PMI subscription.
wpfAdmin.bat setStatisticsType [TransactionCount|ResponseTime] --id PMI_SUBSCRIPTION_ID
wpfadmin setStatisticsType [TransactionCount|ResponseTime] --id PMI_SUBSCRIPTION_ID
You can also use Java™ code, jacl script, or jython script to get the com.ibm.websphere.wpf.jmx.WPFJMX MBean instance, and change the statistics type through the MBean.
- Execute wpfadmin setStatisticsType TransactionCount --id 1 to change the statistics type to TransactionCount.
- Wait for 60 seconds, and retrieve the statistics by executing wpfadmin getTransactionCount --id 1. You will get the following output:
PartitionName TrnsctnCnt TtlRspnsTm MinTime MaxTime StartTime SumOfSqrs PK000010 3 1543 260 671 1094180667170 892385 PK000009 3 369 21 242 1094180667070 70241 PK000008 3 932 99 482 1094180666990 365326 PK000007 3 396 25 200 1094180666829 69866 PK000006 3 392 75 236 1094180666759 67882
The statistics changed very little from the last output. The orders of TransactionCount and TotalResponseTime column are exchanged. However, using TransactionCount instead of TotalResponseTime sorts this output.
