The STATUS for the session is INACTIVE . That would mean that the query completed executing -- what you seem to think as the "query is still running" would be that the results are still being sent to to the SQLPlus client. If you query V$SESSION_WAIT you would see 'SQL*Net message to client' and 'SQL*Net message from client' waits for every batch (arraysize) of rows being sent.
