RMAN-04006: error from auxiliary database: ORA-12514: TNS:listener does not currently know of service requested in connect descriptor
这个报错来自于备库，备库监听没有监听到连接串，定位到主库tnsname.ora或者是备库的listener.ora 有错。 好好检查
九：报错 说 控制文件 不能创建 你应该看看 参数文件里面制定的控制文件的位置 是不是存在 或者oracle用户是不是有权限。

十：结合告警日志分析，以下报错 一般都是路径的问题 db_file_name_convert、log_file_name_convert 一定要写对，并且保证备库的路径那有足够的空间，

十一：主库tnsname.ora 里面添加备库信息的连接字符串（就是开头的名字）必须和主库参数LOG_ARCHIVE_DEST_2='SERVICE=这里的名字。
否则duplicate 报错，Error is 12154 关于tns 的报错。
十二：磁盘空间不足 导致报错 解决 换路径 db_file_name_cencort 后面关于备库的路径换个空间大的。
