JDeveloper
Client Application
Remotely Debugging PL/SQL:
Explicit Calls
1. Start the debugger listener in JDeveloper (Listen for
JPDA)
2. Modify the client code to attach to the debugger
listener from the database session:
DBMS_DEBUG_JDWP.CONNECT_TCP (‘host’, port);
3. Initiate procedure call from the same database
session, for example:
EXEC my_procedure;
4. Modify the client code to terminate the connection
with the debug listener:
DBMS_DEBUG_JDWP.DISCONNECT_TCP();
Remotely Debugging PL/SQL:
Implicit Calls

Two-tier OCI applications
–
–

Set environment variable
set ora_debug_jdwp =
host12.acme.com;port=4040
OCI layer transparently calls the server-side PL/SQL to
connect with the debugger listener
Web mod_plsql applications
–
–
–
Create a UI form to set a cookie in the browser
Pass the hostname and port to owa_debug package
owa_debug transparently calls the server-side PL/SQL to
connect with the debugger listener for each subsequent
page requested by that browser
