Re: reclamation tape predicting

Another approach is not to use reclamation, to avoid the
unpredictability...
I will assume that it is a subset of primary storage tapes which are
ejected
from the library and stored somewhere outside it.
Leave your outside-library tapes unavailable for reclamation.
When housekeeping time arrives, have a dsmadmc-driven programette
query for
external primary tapes which have enough space worth reclaiming, then
call
for their reinsertion; then Checkin and perform 'MOVe Data ...
RECONStruct=Yes'
on each volume in turn. You will likely have to operate on just a few
tapes at
a time due to your library cell constraints. Checkout as needed.
This is a pain, but operating a library in other than "enterprise"
mode makes
for such irregularities. Your management may want to assess the cost of
implementing such a scheme against the cost of additional library space.
