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
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：
