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 D E M O N S T R A T I O N PL/SQL Development Summary JDeveloper is a complete development environment for SQL and PL/SQL in addition to Java and XML QUESTIONS ANSWERS
