Backing Up Oracle Using Tivoli Storage Management

34 Backing Up Oracle using Tivoli Storage Management

TSM backup-archive client: Tivoli software program that allows data objects

to be sent to a TSM server. This typically consists of the files and directories

on a computer, but can include other data objects (that is, Windows 2000

System Object, UNIX Raw Logical Volume)

TSM Application Program Interface (API): Tivoli software that

programmers use to interface with the TSM server. The TSM API is used by

both Tivoli Data Protection products and other vendor products to send data

objects to the TSM server.

4.3 Similarities between TSM and database software

In a computing environment, machines are typically referred to as either

workstations or servers. The difference between these types of machines is

that the servers are running software that provides services to other

machines, the workstations.

An Oracle or DB2 server is a computer that is running the database server

code. When the database server code is running, you can connect to the

database using an administration client or an application client. The

administration or application client can be running on the same machine as

the database server or on a different machine.

Likewise, a TSM server is a computer that is running the TSM server code.

When the TSM server code is running you can connect to the TSM server

using an administration client, a backup-archive client, or an API client. The

administration client, backup-archive client, or API client can be running on

the same machine as the TSM server or on a different machine.

The purpose of the database server is to provide database services to an

application client. For databases, the base functionality provided by the

database server is viewing, adding, changing, or deleting rows or cells from

tables. All other functionality hinges off this base functionality.

The purpose of the TSM server is to provide storage services to a

backup-archive client or API client. The base functionality provided by the

TSM server is storage of a data object and retrieval of that data object.

A database administrator (DBA) uses an administrative client to administer

the database. Typical tasks include creating new databases, adding

additional storage space to tablespaces, backup, recovery, daily monitoring,

and managing authorization.
