The port on which the AVM opens a socket for connecting to the attachable Debugger. If you want the AVM to find an available port, enter 0 (zero). The default value is 0.
An ABL developer can attach the attachable Debugger to any OpenEdge session running locally or remotely in a LAN environment. This allows the developer to run the Debugger on one machine and debug an OpenEdge process running on another machine.
You cannot specify both the Debugger (-debug) and Enable
Attachable Debugging (-debugReady) startup parameters on the command line
at the same time. If you do, the AVM generates an error and shuts down.
For more information about the attachable Debugger, see Troubleshoot ABL Applications.
