Oracle DMS Application

well well, I discovered that there is a "DMS Application" deployed on WebLogic, and if you http://localhost:7001/dms (provide your weblogic login at the prompt)
you end up in a primitive but interesting Web Application with plenty of documentation on all the MBeans available

Let alone the capacity to navigate and interrogate MBeans, the dms webapp is also valuable for all the documentation it provides (click on Metrics Definition)

For example the JVM_MemoryPool and the JVM_MemorySet bring valuable information on the JVM memory utilization :


JVM_MemoryPool
