4.4.2 Installing the TSM client This step includes installing the TSM backup-archive client, TSM API, and the TSM Tivoli Data Protection product. Each of these pieces can be updated independent of the others. However the TSM backup-archive client and the TDP product each are shipped with their own version of the TSM API. You may encounter situations where upgrading the TSM backup-archive client or upgrading the TSM Tivoli Data Protection product may change the TSM API level. The backup-archive client is not required in order to do Tivoli Data Protection or DB2 backups. It is needed in order to use TSM scheduling or to backup files and directories that the TDP or DB2 programs are unable to. Some products like DB2 provide native support for TSM, a TDP product is not necessary. The only thing required to do DB2 backups using TSM is to install and configure the TSM API. 4.4.3 Configuring the TSM client In order to configure the TSM client, you must perform the following tasks: set the environment variables, create and specify options in the client options file, set up the scheduler, and perform configuration tasks specific to the TDP product being used. TSM client programs cannot discover TSM servers on a network. The communication method and the address of the TSM server must be specified in a client options file. The client options file is a plain text file, whose default name is dsm.opt. On UNIX systems, the client options file is a combination of two plain text files, dsm.opt and dsm.sys. The TSM backup-archive client looks for the client options file in a default location or in a location specified by environment variables. The environment variables that are used are DSM_CONFIG, DSM_DIR, and DSM_LOG. All products that interface with the TSM server through the TSM API use a different set of environment variables. The environment variables that are used are DSMI_CONFIG, DSMI_DIR, and DSMI_LOG. If these environment values are not set, default values are used that are different than the default values that the TSM backup-archive client uses. 36 Backing Up Oracle using Tivoli Storage Management
4.5 Managing data objects The TSM server provides storage and retrieval of data objects for TSM clients. When the TSM server stores a data object, it requires the TSM client to provide three types of information: 4.5.1 Archive or data object Whether to manage the data object as a backup or an archive object A description of the data object The management class to bind the object to The TSM server stores and manages data objects as either backup objects or archive objects. The TSM client determines whether the data object is sent to the TSM server as an archive object or a backup object. With the backup-archive client, you send a file or directory as a backup object by invoking the incremental or selective backup command. To send a data object as an archive object, you invoke the archive command. TDP and API products store data objects as backup or archive objects based on how the programmers wrote the code. TDP for Oracle stores database and tablespace backups as backup objects on TSM storage. 4.5.2 Description of data object When a data object is sent, the TSM server places the copy of the client data out on TSM pre-allocated storage (in a storage pool) and records information in its own internal database describing the object. This description includes such things as the node name, filespace name, high level qualifier, low level qualifier, management class. This information is stored in a TSM internal table that can be queried using an SQL select statement. For backup objects, you can run the command, select * from backups. For archive objects you use the command, select * from archives. Both commands are run using the TSM Administrative command line program (dsmadmc). 4.5.2.1 Viewing the description of a backup object Information about each backup object is stored in a TSM internal database table named backups. You can use an SQL select statement to view the entries in this table. We will restrict the output of the select command by nodename. Before running this command, we did an Oracle RMAN backup of a database using Tivoli Storage Manager. Chapter 4. TSM server considerations 37
