  • RMAN备份之非归档模式下的备份

    Backing Up a Database in NOARCHIVELOG Mode:
    1.Log into RMAN
    2.Shutdown immediate from RMAN
    3.Startup mount from RMAN
    4.backup database
    5.alter database open
    --------------------------------------------
    If a database runs in NOARCHIVELOG mode, then the only valid database backup is a consistent backup. For the backup to be consistent, the database must be
    mounted after a consistent shutdown. No recovery is required after restoring the backup.
    To make a consistent database backup:
    1. Start RMAN and connect to a target database.
    2. Shut down the database consistently and then mount it. For example, enter the following commands to guarantee that the database is in a consistent state for a
    backup:
    RMAN> SHUTDOWN IMMEDIATE;
    RMAN> STARTUP FORCE DBA;
    RMAN> SHUTDOWN IMMEDIATE;
    RMAN> STARTUP MOUNT;

    3. Run the BACKUP DATABASE command.
    For example, enter the following command at the RMAN prompt to back up the database to the default backup device:
    RMAN> BACKUP DATABASE;
    The following variation of the command creates image copy backups of all data files in the database:
    RMAN> BACKUP AS COPY DATABASE;
    4. Open the database and resume normal operations.
    The following command opens the database:
    RMAN> ALTER DATABASE OPEN;
