How to Start the WebLogic Server in Debug Mode

Starting the WebLogic Server in Debug Mode

To start the WebLogic Managed Server in debug mode (not the Admin Server).

Use the following procedure to start the WebLogic Managed Server in debug mode:

1. Stop both the Admin Server and Managed Server if they are still running.
2. Go to directory <WEBLOGIC_HOME>/user_projects/domains/<DOMAIN>/bin.
3. Copy the existing startWebLogic.sh script to a new script file, startWebLogic_Debug.sh.
4. Use a text editor to open startWebLogic_Debug.sh.
5. After the line ${JAVA_HOME}/bin/java ${JAVA_VM} –version, add the following two lines:

   echo "Launching Java with debug port: 10171"
    
   JAVA_OPTIONS="-Xdebug -Djava.compiler=NONE -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,address=10171,suspend=n $JAVA_OPTIONS"
   

   The debug port does not have to be 10171 if the port specified is available.
6. Save this change.
7. Copy the existing startManagedWebLogic.sh script to a new script file, startManagedWebLogic_Debug.sh.
8. Use a text editor to open startManagedWebLogic_Debug.sh.
9. Find the two lines that are referring to startWebLogic.sh.
10. Replace startWebLogic.sh with startWeblogic_Debug.sh. This change is to start the WebLogic Managed Server in debug mode by invoking thestartWebLogic_Debug.sh script.
11. Save this change.
12. Start the Admin Server by running the usual start-up script, startWebLogic.sh.
13. Start the Managed Server in debug mode by running the new script, startManagedWebLogic_Debug.sh.

Using the WebLogic Admin Console, navigate to the ‘Server Start’ properties of the managed server that hosts LiveCycle. Add the following to the ‘Arguments’ field. The port used (1044) should be available on the node:
-Xdebug -Xrunjdwp:transport=dt_socket,address=1044,server=y,suspend=n

Re-start the managed server. Point your debugger at the debug port (1044 in the example above).

If the managed server is being started from a script, the debug arguments should be added to the startup script, instead of within the Admin Console.
