2. Using RMAN
- 2.1 Configure RMAN options for the PROD database
- 2.1.1 Turn backup optimization on
- 2.1.2 Set your default channel to write to /home/oracle/backup (you may have to create this directory )
- 2.1.3 Turn on controlfile autobackups to write to /home/oracle/backup/control (you may have to create this directory)
- 2.1.4 Configure a retention window of 7 days.
首先创建两个文件夹
[oracle@ocm1 ~]$ mkdir /home/oracle/backup
[oracle@ocm1 ~]$ mkdir /home/oracle/backup/control
按以下操作：
RMAN> show all;
RMAN configuration parameters are:

- 2.2 Perform a backup
- 2.2.1 Perform a backup using your default channel with compression
- 2.2.2 Include all datafiles in the backup
- 2.2.3 Include your current control file and spfile
- 2.2.4 Include all archive logs, then remove the originals.
备份，使用缺省通道，压缩备份，包括所有文件，包括当前的控制文件的spfile文件，包括所有的归档日志，并将原来的归档日志移除。
