1 前提：备份数据库
查看数据库的模式
SYS@orcl>select open_mode,log_mode from v$database;OPEN_MODE LOG_MODE
-------------------- ------------
READ WRITE ARCHIVELOG
修改RMAN的备份参数
RMAN> configure controlfile autobackup on;new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP ON;
new RMAN configuration parameters are successfully storedRMAN> configure controlfile autobackup format for device type disk to '/tmp/backup/%F';old RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/tmp/backup/cs_%F';
new RMAN configuration parameters:
CONFIGURE CONTROLFILE AUTOBACKUP FORMAT FOR DEVICE TYPE DISK TO '/tmp/backup/%F';
new RMAN configuration parameters are successfully stored
创建测试表空间，并存放数据
SYS@orcl>create tablespace tbs02 datafile '/u01/app/oracle/oradata/orcl/tbs002.dbf' size 1m;Tablespace created.SYS@orcl>create table bruce.test01 tablespace tbs02 as select * from emp;Table created.SYS@orcl>select count(*) from bruce.test01;COUNT(*)

在RMAN下面备份数据库
