Remote debugging means debugging a
different session
That session can be on any server or client
You need to know the user name running
You need to attach the client to the server via a
debugger listener
Start Remote Debugger
Debugger Listener
Attach Client to Debugger
Need to connect client to debugger
Can be run from a stored procedure
EXEC DBMS_DEBUG_JDWP.CONNECT_TCP(
'localhost', '4000');
Attach Client to Debugger
