Flight Recorder Benefits

For JRockit Mission Control version 4.0 and later, the JRockit Flight Recorder replaces the JRockit Runtime Analyzer (JRA) as the easiest way to review system and application performance over time. The Flight Recorder improves upon the JRA by offering a low-to-zero overhead process that has the following benefits:

• Always on: No longer do you need to restart a broken application and create a recording. Since the Flight Recorder will be running at the time the system crashes or other problem occurs, it will provide you with information from before the time you were alerted to the problem. Runtime analysis data will always be available in the buffer; you will already have a record of the problem and be able to diagnose it based upon the actual event. This feature is also helpful for diagnosing intermittent problems since you don't have to start a recording and hope that whatever was causing the problem happens again.

• Better data: The Flight Recorder combines data generated by the JRA and the JRockit Latency Analysis Tool and presents it in one place.

• Allows for third-party event providers: A set of APIs allow the Flight Recorder to monitor third-party applications, including WebLogic Server and other Oracle products. This means that you will receive JVM-level detail combined with logic from the Java application running on Oracle JRockit.

• Reduces total cost of ownership. Because you will spend less time diagnosing and troubleshooting problems, the JFR helps reduces operating costs, reduce business interrupts, provides faster resolution time when problems occurs, and Improves system efficiency.
