Runtime Performance Advisor uses Performance Monitoring Infrastructure (PMI) data to provide recommendations for performance tuning.

The Runtime Performance Advisor uses PMI data to provide recommendations for performance tuning. Running in the JVM of the application server, this advisor periodically checks for inefficient settings, and issues recommendations as standard product warning messages.

The Runtime Performance Advisor recommendations are displayed in two locations:

• The WAS SystemOut.log log file.

• The Runtime Messages panel in the administrative console...
