The estimate recoverable space is 40GB! -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Loon, EJ van - SPLXM Sent: 04 April 2013 03:30 PM To: [email protected] Subject: Re: [ADSM-L] TSM 5.6 reorg
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?

No spare storage available to will have to recover to tape. Is this something that could be achieved in 8-10 hours time? -----Original Message----- From: ADSM: Dist Stor Manager [mailto:[email protected]] On Behalf Of Loon, EJ van - SPLXM Sent: 04 April 2013 03:12 PM To: [email protected] Subject: Re: [ADSM-L] TSM 5.6 reorg 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.
