You can configure the Runtime Performance Advisor using the wsadmin tool or the administrative console.
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 administrative 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.
