Delete/Redefine! All my CICS regions have different sized GCD/LCD/RSDs - I
could keep define card for each dataset but there's a risk the size changes
and someone forgets to update the define cards.
I got around this problem by using REPRO & REUSE - and REPRO the INIT
records to the GCD/LCD - it works just the same - but no del/def and all the
risks with that (like the del works but someone takes the space before the
def!)

As for the check it was a clean shutdown - we use a simple dataset creation
at the end of CICS and then check that that dataset exists at startup before
doing the Del/Def bit.

I can post the JCL if you want it.
