Oke, but isn't buying extra space much cheaper than you spending a whole
day recovering 40 Gb? Anyway, it's your party, but for me wouldn't be
worth the work and risk...

The estimate recoverable space is 40GB!

Hi Jerome!
I doubt it will be possible in 10 hours. Anyway, 8% seems kind of low to
me, not much fragmentation. What are you hoping to gain from the
unload/load?

Thanks Eric,
Fragmentation is at 8.02%. No spare storage available to will have to
recover to tape.
Is this something that could be achieved in 8-10 hours time?

Hi Jerome!
The performance of the unload/load process is hardly predictable.
Performance varies enormously during the unload process and seems to be
related to the amount of fragmentation. You can get an idea about your
fragmentation by running the following SQL query:
SELECT CAST((100 - (CAST(MAX_REDUCTION_MB AS FLOAT) * 256 ) / -
(CAST(USABLE_PAGES AS FLOAT) - CAST(USED_PAGES AS FLOAT) ) * 100)
AS -
DECIMAL(4,2)) AS PERCENT_FRAG FROM DB The read performance of the
database is also crucial to the unload performance, if possible place
your database on (multiple) SSD disks.

Hi All,
I am about to reorg my 200GB TSM DB this weekend. Anyone know
approximately how long it will take to complete?
Thanks
Jerome
