ORACLE链接错误解决方案

情景：远程服务器安装oralcle服务，远程可以通过sqlplus连接，本地连接报错ORA-1247丢失连接；

解决方法：

• 将远程服务器的tnsnames文件中的localhost改为ip地址，如下：

ORCL =(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = localhost10.0.13.123)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

• 将远程服务器的listener文件中的添加ip地址，如下：

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 10.0.13.89)(PORT = 1521))
)
)

重启之后报错ORA-12514:TNS:监听程序当前无法识别连接描述符中请求的服务

解决方法：添加如下代码

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = E:\app\Administrator\product\11.2.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:E:\app\Administrator\product\11.2.0\dbhome_1\bin\oraclr11.dll")
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = D:\app\Administrator\product\11.2.0\dbhome_1)
(SID_NAME = orcl)
)
)

重启监听，连接成功。
