![]() Installation of legacy Oracle Java Embedded Products. We have more than 4000+ system properties to configure the runtime and 600+ technology extensions libraries so it might be overkill unless one has a complex problem to solve and/or using the same tool across development, test and production is paramount. JRockit Mission Control Java for Business JRE Java for Business JDK The legacy Java for Business offering has been replaced with Oracle Java SE Advanced, Oracle Java SE Advanced Desktop or Oracle Java SE Suite. ![]() We need a small server tool called jstatd to listen on a couple of ports for VisualVM to communicate with and attach to running JVMs. The JRE is installed because Java processes are running. I should be point out that JXInsight is designed for software performance engineers and not just for the occasional adhoc profiling session. Install the Java JDK on the remote system.

Java Mission Control (jmc.exe) Diagnostic Command Tool (jcmd.exe) We suggest exploring the content of this folder to be aware of what tools we have at our disposal. I am the architect of JXInsight so of course I am completely biased but at the same time I am probably more qualified than most in the Java industry to make such a claim since I have devoted the last 8 years to performance analysis for some of the most demanding of Java/J2EE application in production. Some commercial profilers offer free licenses for open-source projects, like JProfiler. JXInsight's Probes technology is also the only one that could even run in production considering that we out perform netbeans profiler by 20x and yourkit 100x in SPECjvm2008 benchmarks. ![]() None of the tools other than JXInsight perform real database transaction analysis: ![]()
