已使用的参数文件:
c:\u01\oracle\product\11.2.0\dbhome_1\network\admin\sqlnet.ora


已使用 TNSNAMES 适配器来解析别名
尝试连接 (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.56.105)(PORT
= 1521)) (CONNECT_DATA = (SERVER = SHARED) (SERVICE_NAME = GT11G)))
OK (10 毫秒)

原因是RMAN要使用DEDICATED也就是专用服务器类型才能连接，而不能使用MTS的shared连接，修改后即可正常连接：
