Enable the Runtime Performance Advisor tool using scripting

 

You can configure the Runtime Performance Advisor using the wsadmin tool or the console. Before starting this task, the wsadmin tool must be running. See the Start the wsadmin scripting client article for more information.

 

Overview

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

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. You can 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. You can enable the following counters using the Runtime Performance Advisor:

ThreadPools (module)
Web Container (module)
Pool Size
