Solution
The following privileges are required for debugger:

1. DEBUG CONNECT SESSION
Connect the current session to a debugger that uses the Java Debug Wire Protocol (JDWP).

2.DEBUG ANY PROCEDURE
Debug all PL/SQL and Java code in any database object. Granting this privilege is equivalent to granting the DEBUG object privilege on all applicable objects in the database.

Syntax
GRANT DEBUG CONNECT SESSION TO user_name ;
GRANT DEBUG ANY PROCEDURE TO user_name;
