This illustration shows the continuation of steps in the target session:

• Initialize using DBMS_DEBUG.attach_session()
• Manipulate the breakpoints using:
  • DBMS_DEBUG.set_breakpoint()
  • DBMS_DEBUG.delete_breakpoint()
  • DBMS_DEBUG.disable_breakpoint()
  • DBMS_DEBUG.enable_breakpoint()
  • DBMS_DEBUG.show_breakpoint()
• Read first event from the target session using DBMS_DEBUG.synchronize()
• Show the stack using DBMS_DEBUG.print_backtrace()
• Get/set values using:
  • DBMS_DEBUG.get_value()
  • DBMS_DEBUG.set_value()
• Manipulate the breakpoints
• Show the source by using DBMS_DEBUG.show_source().
