Info

you can save time by sending the biggest objects straight to tape. This way all of your client sessions can be sending data to either disk or tape, and you do not have client sessions waiting on migration to finish. The other reason you save time is because the end result of migration is that the objects end up on tape. If you send it straight to tape, you do not spend the time sending it to disk, then migrating it to tape. We updated our storage pool so that the maxfile size was 50% of the total size of the disk storage pool: update stgpool api_disk maxsize=2g Using dedicated storage pools Dedicated in this context means that the storage pool is reserved for one specific client. No other client sends files to this storage pool. There is no configuration parameter to implement this. It is a matter of how the policy setup had been done. There are different reasons why you may wish to use dedicated storage pools. Certain TSM server processes operate based on the storage pool, and you may want have the server processes affect only certain clients. The workaround for this is to send these clients to dedicated storage pools, you can then run the TSM server processes on these dedicated storage pools separate from your standard storage pools. Among these processes, the use of copy storage pools, collocation, and reclamation may warrant the use of dedicated storage pools. Copying storage pools To safeguard against defective tapes, copy storage pools can be used. If you have dedicated storage pools you can be more flexible in which data should be copied to a copy storage pool and which not. As backups and logfiles are often very critical to a company these data are a good candidate to be copied. It may be useful to define a dedicated storage pool for the backup copy group and the archive copy group and only setup the archive copy group (containing the logfiles) to be copied to a copy storage pool. Reclamation It should be the responsibility of the Oracle administrator to delete old backups. If the Oracle database administrator decides to delete all database backups after they reached a well defined age, all these files will expire naturally. If these files reside in a dedicated tape pool reserved for the Oracle client, the reclaim value of this tape pool can be set to a very high value. There is no need of doing much reclamation if the files will be deleted anyway. 54 Backing Up Oracle using Tivoli Storage Management
4.10 Our TSM server setup In this section we show the specific setup that we used for our existing TSM server in order to be ready to receive the Oracle backup files. Our existing environment already contained the following components: TSM server 4.1.2 TSM client 4.1.1 Atape driver 5.4.4.0 Ultrium Tape Library 3583 with two 3580 tape drives. 10 formatted disk volumes named vol1 to vol10 each 2GB in size. In the first step, we create the domain the policy and the management class: tsm: BRAZIL>def domain api_domain DESC='DO for all DB-Backups' ANR1500I Policy domain API_DOMAIN defined. tsm: BRAZIL> tsm: BRAZIL>def policyset api_domain api_policy DESC='PO for all DB Backups' ANR1510I Policy set API_POLICY defined in policy domain API_DOMAIN. tsm: BRAZIL>def mgmtclass api_domain api_policy api_mgmtclass DESC='MC for all DB-Ba ckups' ANR1520I Management class API_MGMTCLASS defined in policy domain API_DOMAIN, set API_POLICY. tsm: BRAZIL> Next, the tape and disk storage pools are being created, and some pre-formatted disk volumes are assigned to the disk pool: tsm: BRAZIL>def stgpool api_3580_a 3580class DESC='Archive tape pool' rec=95 maxscr=10 maxsize-10g ANR2200I Storage pool API_3580_A defined (device class 3580CLASS). tsm: BRAZIL>def stgpool api_3580_b 3580class DESC='Backup tape pool' rec=95 maxscr=10 maxsize-10g ANR2200I Storage pool API_3580_B defined (device class 3580CLASS). tsm: BRAZIL> Chapter 4.
