How to get the standard java tools like jconsole, jps and jstat working for OC4J on windows.
These sometimes do not work out of the box, either they will not find the PID (process ID) of the java process to monitor, or they will throw the error:
Exception in thread "main" java.lang.Exception: Could not open PerfMemory
IAS 10.1.3 uses version 1.5 of the JDK and there are some useful tools provided. Unfortunately for the windows platform the tools available in this version are not nearly as comprehensive as solaris or linux
(which have things like jmap , jinfo and jstack) but on windows you do at least get:
jps : list java processes
jstat : print detailed stats on JVM operation
jconsole : A graphical, easy-to-use monitoring console
