1、如果是windows系统，先看看oracle的SID，然后在DOS里面设置一下SID
命令set ORACLE_SID=test
2、Linux中，查看oracle数据库的SID号，用如下命令：
3、rman的参数及说明

4、注意这里的说明
Both single and double quotes (' or ") are accepted for a quoted-string.
Quotes are not required unless the string contains embedded white-space.
如果字符串中没有空格字符，可以不使用引号
直接输入rman即可进入rman，注意这里rman必须小写
5、输入connect target / 连接数据库
6、输入exit，可以退出rman
