Well, OK - there can be 1 to many IMS regions running concurrently. You can stop a region without bringing down IMS. I will assume (?) that you do not run BMP? So, IMS is brought "down" - made unavailable - for a certain portion of the day/night. This is when DLI batch jobs run and backups of the databases are done.
