This plugin is used to extend the JConsole that is bundled as part of the 1.5 .0 JDK.

Download

The latest OpenJPA Tools JAR file can be download from the SNAPSHOT Repository or can be built from the source code in svn by using Maven 2.2.1 and Java SE 6.

This description assumes your application is running the on same machine as JConsole and application JVM matches the JConsole and you are running with an Oracle JVM (it will work on IBM, but you'll need to do a little more work).

1. Start an OpenJPA application with the following configuration properties set:

   Code Block
   xml xml
   <property name="openjpa.DataCache" value="true"/> <property name="openjpa.Instrumentation" value="jmx(Instrument='DataCache')"/>

2. Launch JConsole and provide the openjpa-tools.jar via the -pluginpath switch.

   Code Block
   > [java_home]\bin\jconsole -pluginpath [path _to _openjpa-tools.jar]

3. Select the PID which corresponds to your application.
