Re: AW: Unload db/Loaddb
DUMPDB/LOADDB - is used when the database is corrupted, and audit db doesn't solve the problem. DUMPDB increases the size of the database. UNLOADDB/LOADDB - rearrange the structure of the database, this would in most cases result in better search performance and a smaller database.

Re: AW: Unload db/Loaddb
I just completed a dump/reload of my database of a version 4.1.4 server It was a 3 gb db showing 80% utilization. After the reload I'm down to 24% My problem was with the 4.1 documentation, try as I might it wouldn't work with the loadformat step until a ran a dsmfmt of the logvolumes and the db voilumes first.

Re: Unload db/Loaddb
Rajesh, I have performed an unload/reload of our AIX TSM server, and recieved the following results: Reduced database utilization by - 21.2% Reduced used database pages by - 3,114,592 Maximum database reduction increased by - 22,044mb Our TSM production database is 60gb in size. It took 8.5hrs to unload the database, and 4.0hrs to reload the database. Two of the biggest benefits that we saw were a reduction of runtime for Expire Inventory, and the time it took to perform a FULL TSM Database backup.

Re: Unload db/Loaddb
How long did these benefits last? We are going to do the same thing, with a 48GB database. On our test system, it was redeuced to 26GB, but I have no load there to find out how long the benefits will last, and how often I will have to do this.

Re: Unload db/Loaddb
My db shrank a lot also, but re-grew a fair bit over the next week. I suspect it will reach a steady-state value not much different than I started with. Orville L. Lantto Datatrend Technologies, Inc.

This is what I plan to do: - wait for DB backup to complete - enter 'halt quiesce command so the db should be consistent - unloaddb (to disk) - loaddb (from disk) In testing, with out full size DB (47.9GB), it went down to 28.6GB. I am very happy with the results, and am anxious to do it on the prod server.

Re: Unload DB/LoadDB
Matt, many people on this list have larger DB. What is your concern about the database - performance, DB backup time, ... ? If there is a problem other than size provide some details - version, DBVols and LOGVols storage type, etc. Unload/Load may help to reduce the DB but may not as well. You can argue against no off-site reclamation. At the end through such reclaim not only tape usage is better but also chance for tape errors due to aging is minimized.
