My TSM db had never been unloaded and reloaded when I set out to do it this past thanksgiving.
I've got my DB on 9GB SSA volumes, one spindle per logical volume, one filesystem per lv, one volume per filesystem. 4-cpu power3 node (?) Wide winterhawk SP node? I get tangled up in the hardware numbers. 4GB ram. It began at ~45GB used. Unload took 10 hours Loadformat took 2 minutes Load took 6 hours (!) I was expecting quite a bit more. Currently down to ~30GB. DB backup times cut by (shocker) roughly 1/3. Expiration dramatically faster. Cache hit is at 99.49, had been down around 98. I am interested to see how much faster another unload will run. Maybe (sigh) Christmas day. If I can get them down to 12 hours total, I'll be much happier. Then I can think about scheduling it twice a year or something. When I thought it was going to take ~24, that was a Problem With a Captial P. - Allen S. Rout
