3.2.1 Offline Backup of the Database
configure_nsrora and configure_networker can be used, if required, to create a
new client and a new group called OFFLINE<oracle_sid><client>. If this client is
backed up, an offline backup is performed, i.e. the database is shut down before
the backup and then rebooted after the backup.
Furthermore, an offline backup of the database is performed whenever the
database is closed at the time of the backup. This procedure consists of the
following phases:
DBMS
control file
USER
database files
redolog files
SYSTEM TEMP
Tablespaces
Oracle’s
