Are you backing your database up regularly? If not, that is probably why you are not complaining yet. If you lose the database, the data on the tapes is inaccessible.
My databases is about 15M pages and has never had an unload/load performed to reorg it. I plan on doing it soon. The estimate is it will reduce the database by 50% Are you running expiration and reclaimation yet. That may explain some of your growth if you are not. Also, the default for reclamation is 100%, so the tape has to be completely empty before TSM will reclaim the tape. You may want to check your storage pools. The general recommendation is between 50% and 70% empty depending on your situation. 30GB database is pushing for a Windows NT enviroment unless you have really good disk attached to it such as high end, ESS, HDS, or EMC disk. Have you looked at your policies for retention. Depending on how you set them up, you could really be chewing up some tapes. Are you using any collocation? Take a look at your occupancy usage by using a "q occ" to get the usage. Issue a "q volume" to see what the usage is of your volumes. Welcome to the best product in the business for this type of data. It does have challenges. The List will help you.

Being new to TSM, I have a few questions I was hoping someone may be able to help with. I am running TSM 4.2.1.9 with a Compaq ESL9198DLX on W2K 1) Our TSM database has grown surprisingly fast. We tend to backup LOTS of little tiny files and as a result our Database is currently around 30Gb. I understand that the technical limit for the DB is somewhere around 5TB. Should I be concerned running a 30GB database on NT using a single server? Would this be considered a small, average or large TSM installation? 2) We've also found that our library is a little under-sized. (I regularly find myself exporting tapes from our primary tape storage pool to make room for scratch media). I would like to replace two or three of the DLT40/80 drives in the library with SDLT units. The ESL9198 hardware will support Mixing DLT and SDLT drives and media. Does any know or have experience setting up a library with two media types? Would TSM support this type of environment? Any help or information anyone can provide would be greatly appreciated!
