I have a situation here, online application based on 3 tiers. the GUI tier is build using GWT. we also have an EJB tier as a business tier. We use oracle application server.
Is there is some tool to be installed on the application server to give a report of what functions consume the CPU usage? I face 90% CPU usage on the application server always at the end of the working day, and i want exactly to catch what is the main cause of that.
