I did understand that damaged objects could be fixed or cleaned with RCLSTG.  I
run a compact on Notes files nightly.  I have occasionally found objects with no
libraries.  I did do a 'compress' on the S/36 regularly.  My SAVSYS takes about
4 hours to a high speed 3581 tape drive.  I have 53Gig that is pushing 80% full,
what would you guess RCLSTG would take ....  12-14 hours?  Any idea?

Gail,

I can think of a few reasons to run the command.  Because it can be an
extremely long-running command and requires a dedicated system, your
organization's requirements for system availability will often determine
whether you run it casually or only in emergencies.

Here are some reasons:

- Your system has lost power in the middle of a production day.  You
have no UPS so it crashes hard.  When you bring the system back up, you
start receiving messages about damaged objects.  At this point you could
run the RCLSTG command to fix whatever damage can be fixed and move the
permanently damaged objects to a safe place.  It will also find objects
which have no owner and objects which have lost their association with a
library or directory.

- You have an appropriate period of time in which you can dedicate the
system and you want to do some housekeeping.  The idea of an annual
RCLSTG is a good one if your system has the availability.  Running it
weekly would be overkill, or an indication that you have serious
problems.

- You have been creating and deleting libraries containing many database
files.  When you look at the system cross-reference tables you find a
very large percentage of deleted records.  While this isn't a 'problem',
you can get the space back by running the RCLSTG command.  If this is
the only reason you're running it, you would use the *DBXREF parameter.

These are some of the reasons.  In response to your original posting
about Domino mail files, these databases are stream file objects in the
IFS.  They will have their system integrity examined and repaired, but
nothing will be done about the space they take up.

Back in the S/38 days (and early AS/400), systems crashed more often.
They would frequently leave objects on the system without a library.
Because they had no library, we could not use the normal system tools to
access or delete them.  Sometimes these would be large database files,
so after running a reclaim we could delete the objects and get back a
lot of storage space.  Maybe that's where the name came from.

Regards,
Andy Nolen-Parkhouse
