This chapter describes the onperf utility, a windowing environment that you can use to monitor the database server performance. The onperf utility monitors the database server running on the UNIX operating system.

The onperf utility allows you to monitor most of the same database server metrics that the onstat utility reports. The onperf utility provides these main advantages over onstat:

• Displays metric values graphically in real time
• Allows you to choose which metrics to monitor
• Allows you to scroll back to previous metric values to analyze a trend
• Allows you to save performance data to a file for review at a later time
