Re: Question - Your IPL Frequency

There's a "secret" time period in days that if your system is not in use,
IBM somehow invalidates the license.  It's somewhere over two months.  Most
people with dormant systems re-IPL them weekly to avoid this restriction,
but this has nothing to do with IPL requirements.

If our 200 (V3R2) is not in use (which is most of the
time), we IPL it once a week, let it run for an hour or
so, then shut it down, in order to keep it exercised. And
this generally happens without anybody even noticing.

The same is true for our 40s (V4R2, one of our 2
development boxes) and our "fat" 170 (our V5R2 test box),
except that they usually do get turned on before their
weekly exercise cycle.

Our "slim" 170 (V4R4, our other development box) and our
510 (V4R5, our production box) run for months at a time
without an IPL. The 170 runs for weeks at a time without
even being brought down to restricted state; the 510 gets
a full backup weekly, and so it hits restricted state
weekly (but without a full cold IPL).
