RE: iTera Reorganize while active software

Tom,

I haven't used that product but a similar one called Turnover PDQ from
SoftLanding.  I assume the products work fairly similar.  CPU load could be
minimized by lowering the priority of the jobs.  Some of the reorg's took
days to happen but everything ran fine during this time.  Actual downtime
was just a few minutes, essentially renaming files.  Had to be very careful
during actual downtime or our mirroring software would put the files
out-of-sync which would mean the live data wouldn't be current on our backup
machine until the file had been resent.  We were in an environment where we
coulnd't afford to RGZPFM and this allowed us to avoid having to purchase
more disk for quite some time.  Some of our reorg's had almost 10 million
deleted records.
