Remote debugging

The easiest way to illustrate remote debugging is to use Oracle SQL Developer with an application in APEX. The subprogram resides in APEX, and Oracle SQL Developer is used to debug it. This capability is especially useful when an application isn't failing but also isn't producing the results you expect. The following grants are necessary before performing remote debugging:

grant DEBUG CONNECT SESSION to <schema>; 
grant DEBUG on <object> to PUBLIC;
grant DEBUG ANY PROCEDURE to APEX_PUBLIC_USER;

Or ANONYMOUS when using the embedded gateway.

1. Connect Oracle SQL Developer and import the APEX application.

2. Set a breakpoint in the code that needs to be debugged.

3. Compile the procedure for debug.

   Note that running a package in debug mode severely hampers performance. Once testing is complete, compile the package without debug information.

4. At this point, prepare Oracle SQL Developer for remote debugging. Do this by selecting the connection that will be used for debugging the...
