Probably best to do a PWRDWNSYS restart after running RCLSTG if
you were to use this on a production box.
It's not pretty but it works.
<<SNIP BCHTIMLMT() CLP to effect reclaim *dbxref>>
There would be little value to perform a PWRDWNSYS after
reclaiming the DB cross-reference. In fact, just the opposite. The
system jobs QDBSRVXR & QDBSRVXR2 [or iASP equivalents] that perform
the work of the reclaim run asynchronous to the requester of RCLSTG,
and so powering down stops the processing, thus making those jobs
continue where they left-off when they were interrupted by the PwrDwn.
FWiW: For a RCLSTG SELECT(*ALL), there was long ago a functional
benefit to powering down just before that request, with a side
effect of some impact to its performance [similar to saves after IPL
versus delaying saves until after normal system utilization over
several hours]. A design change eliminated the pwrdwn as a
pre-requisite to obtain the alluded benefit, but having added an
improbable but potentially highly-negative side effect, which AFaIK
has never been corrected.
