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”.

3.1 The 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 figure4).
