Release 10.1A: OpenEdge Application Server:
Developing AppServer Applications

Summary of debugging requirements

The following requirements must be satisfied before you can debug an AppServer using either distributed debugging or remote debugging:

The Debugger is supported on all platforms that support the Progress 4GL.
You must run the ProDebugEnable command and configure the AppServer for debugging by setting the debuggerEnabled property to 1 in the AppServer properties file (ubroker.properties). If you do not start an AppServer with this property setting, you cannot use the Debugger to debug code on the AppServer.
When you set up an AppServer for debugging, it does not activate the Debugger when the AppServer starts, but when a procedure on the AppServer is executed in the context of a debugging session.
The Debugger (-debug) startup parameter and the DEBUGGER:DEBUG( ) method do not function on the AppServer.
To use the Debugger with:
Distributed debugging, you must start it on the platform where the Progress 4GL client is running.
Remote debugging, you must start it on the platform where the AppServer is running.
