Re: BRMS - full save with least amount of restricted time

[Jim Oberholtzer <midrangel@xxxxxxxxxxxxxxxxx>]

Yes you could just start the controlling subsystem but I would make sure 
you put in some control points and error handling.  That's when a data 
queue comes in really handy.  Have the start up program put an entry 
into the queue.  The CL in the control group waits for the data queue 
entry and off you run.  Now you don't have to guess how long it takes to 
run the start up program.
