经分析后，在TNSNAME.ORA 文档中添加如下内容：

PROD1 =

(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = SOURCE)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = PROD1.oracle.com)
    (server=dedicated)
    )
  )

问题解决。

做BACKUP时只能用独占方式连结.加上(server=dedicated),说明使用独占连接

原因是在登录时使用了服务名：rman target sys/*****@prod1
