3 The individual Components

The individual components for backing up and recovering an ORACLE database in a NetWorker environment are described in the following section. Four different areas are dealt with:

The archiving monitor

The backup component

The recovery component

The overall configuration

Each section starts with a functional description. This is followed by an expla- nation of the required configuration steps, after which the procedure and opera- tions are illustrated with the help of practical examples. Two configuration tools are provided for your convenience: configure_nsrora and configure_networker.

The installation and configuration of NSR-ORA and the two configuration tools are dealt with in chapter “Installation and Configuration”. We recommend you to read through chapter “Introduction” before you start carrying out the installation and configuration described in chapter “Installation and Configuration”.

3.1The Archiving Monitor

During the operation of an ORACLE database, the online redolog files are archived by the database system in an archive directory to protect the database from data losses. For this, the database must be in ARCHIVELOG mode (“Auto- matic archival ENABLED”). However, the database system is not responsible for the subsequent management of the offline redolog files created in this manner. If the archive directory becomes full, your database will come to a halt. This administrative gap is bridged by the archiving monitor (amon) (see figure 4).
