You set rdisp/shutdown/idle_wp_timeout to 0 expecting the soft shutdown to skip waiting on busy work processes. What actually happens?

You need to change the SID, the database host, or which instance provides the enqueue service. Why do these belong in DEFAULT.PFL rather than an instance profile?

Reading a start profile you see both Execute_02 and Start_Program_00 lines. What is the division of labour between the Execute and Start_Program entries?
