Enable the Runtime Performance Advisor tool using scripting


Configure the Runtime Performance Advisor using wsadmin or the admin console.

Before starting this task, wsadmin must be running. See the Start wsadmin article for more information.

The Runtime Performance Advisor tool provides advice to help tune systems for optimal performance. See the Use the Runtime Performance Advisor article for more information on how to enable this tool using the admin console. The recommendations display as text in SystemOut.log.

The Runtime Performance Advisor (RPA) requires that the Performance Monitoring Service (PMI) is enabled. It does not require that individual counters be enabled. When a counter that is needed by the RPA is not enabled, the RPAr will enable it automatically. There is no MBean/object available for wsadmin to create a RPA configuration. Use wsadmin to change the settings and make them effective at runtime. These changes will not be persisted. The changes remain until you stop the server. Since the RPA is disabled once you stop the server, you may want to disable the PMI Service or the counters that were enabled while it was active. We can enable the following counters using the Runtime Performance Advisor:

ThreadPools (module)
Web Container (module)
Pool Size Active Threads
Object Request Broker (module)
Pool Size Active Threads
JDBC Connection Pools (module)
Pool Size Percent used
Prepared Statement Discards
Servlet Session Manager (module)
External Read Size
External Write Size
External Read Time
External Write Time
No Room For New Session
System Data (module)
CPU Utilization Free Memory

The following provides an explanation for some of the settings that we can use:
