Remote Debugging

What is it

Remote debugging enables simple debugging of Batches from inside Eclipse Environment.

You will typically:

• Generate your BAR with maven:
  • mvn clean install
• Copy the BAR to <BATCH_SERVER>/batches-cold-deploy folder
• Start the Batch Server with socket debug
• Configure your Eclipse to Remote Debug one BAR project
• Start The batch with JConsole
• Debug

Setup Batch Server (Done only ONCE per developer Machine)

• 1) Run Batch Server Installer, see Server Installation Guide

• 2) Add DEBUGGING options to Batch Server command line:
  • Edit <INSTALL_FOLDER>/bin/setenv.bat
  • Find JAVA_OPTS
  • Add at end :

-Xdebug -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5006

• • In this example, we put 5006 as debug port (ensure this port is not used)

Setup Eclipse Launcher (ONCE per Batch project)

In Eclipse Select Debug>Debug Configurations:

Fill in:

• Project (your BAR project)
• Host : localhost
• Port : The port you configured in Batch Server in JAVA_OPTS, 5006 in our example:

Start your batch

In JConsole, select "MBeans" tab:

And unfold node hierarchy:

• <BATCH_GROUP>/batch/runtime/<BATCH_NAME> for a classical Batch
• <BATCH_GROUP>/batch/runtime/<BATCH_NAME>__@@__<LAUNCH_NAME> for a Batch with launch

Unfold "Operations" node and click on start

That's it

Now here is what you get:

• You can put DEBUGGING points in your project code to debug your batch
