Connecting to a weblogic cluster via JPDA

Question

I have a weblogic cluster set up across two machines in a staging environment. I'd like to set up JPDA on at least one of the weblogic instances so I can debug remotely. Generally I use wlst.sh and jython scripts to startup the cluster via:

startNodeManager(...)
nmConnect(...)
nmStart(MyAdminServer)
connect(...) #connect to the admin server
start(...) #start the cluster

Where should I put the -Xdebug Xrunjdwp:transport... incantation so that I can attach to one of the weblogic instances? I had no problem setting this up on a single instance through my domain's startWebLogic.sh, but it doesn't seem to work with the cluster.

From here: https://forums.oracle.com/forums/thread.jspa?threadID=2233816 it looks like I want to put the debug string in startManagedWeblogic.sh but that doesn't seem to work with my jython script either.

Figured it out, from http://docs.oracle.com/cd/E13222_01/wls/docs90/server_start/nodemgr.html#1081870:

 4. The Administration Server obtains the domain configuration from its config directory

I checked out the config directory under my domain and there was a suspicious file called config.xml. Within this file is the configuration for the weblogic nodes and where you want to put your JDPA config:

<server>
  <name>my-target-machine</name>
  ...
  <server-start>
    ...
    <arguments>(your other config stuff) -Xrunjdwp:transport=dt_socket,address=4000,server=y,suspend=n</arguments>
