Don't worry about it.
According to a talk I heard from L2 support, the expire inventory
process is optimized and clever.

It looks at the objects belonging to a filespace, expires those that are
ready to expire, but can tell by the dates when it doesn't need to look
further through the filespace for things that have expired.   

So it doesn't have to look at every object in the DB, and "objects
examined" is not an indicator of how many objects you have in the data
base.

Each time it is basicly expiring  files that no longer are required to
meet the definitions in the mangement group.

Perhaps a client deleted a file system and the number of days for
inactive file retention was passed.

Hi *SMers,

i've come across some behaviour of the EXPIRE IVENTORY command which i
don't
understand.

We have a daily job that executes EXPIRE EIVENTORY. Results are shown
in the
Activity Log and read as follows:

09/02/06 07:49:48     ANR0812I Inventory file expiration process 301
completed:
examined 9604 objects, deleting 1929 backup objects, 0
archive objects, 0 DB backup volumes, and 0 recoveryplan files. 0
errors were
encountered.

09/04/06 05:15:35     ANR0812I Inventory file expiration process 313
completed:
examined 40052 objects, deleting 1162 backup
objects, 0 archive objects, 0 DB backup volumes, and 0 recovery
plan files. 0 errors were encountered.

Two things really upset me:
- The numbers of objects examined are significant different, but i am
sure the
database grows very slowly
- A rough estimate for the total number of objects gives a value
somewhere
between 200,000 and 300,000 objects.

Can someone shade a light on this?

Thanks in advance

regards Guenther
