Configuring Automatic Backups for the Control File and Server Parameter File
You can configure RMAN to automatically backup the control file and server parameter file with every backup. This is referred to as an autobackup. The server parameter file and control file are critical to the database and RMAN. Creating automatic backups of the control file enables RMAN to recover the database even if the current control file and server parameter file are lost. The control file and server parameter file are relatively smali compared to typical data files and, therefore, backing them up frequcntly results in relatively little storage overhead.
If the database runs in ARCHIVELOG modę, then an autobackup is also taken whenever
the database structure metadata in the control file changes.
To configure automatic backups for the control file and server parameter file:
1. Conncct RMAN to the targct database as dcscribed in "Connecting to the Target Database" on pagc 9-9.
2. Entcr the following command:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
RMAN uses a default format to assign names for thcse backups.
