Abstract

System Java (TM) applications, like Websphere (TM), are becoming more complex with large start up times. Thus it is becoming increasingly important that analysis and/or debugging does not require system shut down. Current technology does not allow attachment of profiler to the Java Virtual Machine (JVM) after the JVM has started. Thus, there is a growing need for such an attachment. General Solution: Enhance the JVM to support a profiler interface which attaches after the JVM is running. We describe three different approaches to this problem.
