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setORACLE_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Argument Value Description-----------------------------------------------------------------------------target quoted-string connect-string for target databasecatalog quoted-string connect-string for recovery catalognocatalog none if specified, then no recovery catalogcmdfile quoted-string name of input command filelog quoted-string name of output message log filetrace quoted-string name of output debugging message log fileappend none if specified, log is opened in append modedebug optional-args activate debuggingmsgno none show RMAN-nnnn prefix for all messagessend quoted-string send a command to the media managerpipe string building block for pipe namestimeout integer number of seconds to wait for pipe inputchecksyntax none check the command file for syntax errors-----------------------------------------------------------------------------Both single and double quotes (' or ") are accepted for a quoted-string.Quotes are not required unless the string contains embedded white-space.
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
7、如果以上经验帮到您，麻烦在左下角给点个赞，谢谢！
