In order to kill their own sessions, they need to be able to positively identify their own sessions...and that may be problematic. 42 APP_DEV sessions coming from APP_SERVER...which one is the one they want to kill?
I would suggest a two phase approach.
Phase 1 - Provide tools/training for the developer to be able to
positively identify their own session. They can then use the appropriate
information (sid, serial#) as input for a dba to validate the session
and terminate it. This might also provide an opportunity for the dba to
determine the reason (bad sql, bad sql coder, application issues,
database issue) and make corrections.
Phase 2 - Assuming that Phase 1 is successful and the developers have shown the ability and responsibility, the process could be codified and appropriate privileges granted.
