Startup Parameter Descriptions : Enable Attachable Debugging (-debugReady)

Enable Attachable Debugging (-debugReady)

Use Enable Attachable Debugging (-debugReady) to enable an OpenEdge process (that is, an ABL client, a single WebSpeed agent, or single AppServer process) to be attached to by the Debugger.
Operating system and syntax
UNIX / Windows
-debugReady { 0 | port-number }
Use with
Maximum value
Minimum value
Single-user default
Multi-user default
Client Session
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 OpenEdge Development: Debugging and Troubleshooting.
