ORA-12514: TNS: 监听程序当前没法识别链接描述符中请求的服务

ORA-12514: TNS: 监听程序当前没法识别链接描述符中请求的服务

 

在安装完Oracle10g后，使用PL/SQL工具链接，提示以下的问题：

ORA-12514: TNS: 监听程序当前没法识别链接描述符中请求的服务

 

 

解决办法是手动修改监听配置文件：

 

# listener.ora Network Configuration File: d:\oracle\product\10.2.0\client_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
    (SID_LIST =
        (SID_DESC =
            (SID_NAME = PLSExtProc)
            (ORACLE_HOME = d:\oracle\product\10.2.0\client_1)
            (PROGRAM = extproc)
        )
        (SID_DESC =    
            (GLOBAL_DBNAME = ORCL)    
            (ORACLE_HOME = G:\oracle\product\10.2.0\db_1)        
            (SID_NAME = ORCL)    
        )    
    )
LISTENER =
    (DESCRIPTION_LIST =
        (DESCRIPTION =
            (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.100)(PORT = 1521))
            (ADDRESS = (PROTOCOL = IPC)( KEY = EXTPROC0))
        )
    )

 

其中红色粗体部分是添加部分。

 

以上是在一台机器上既安装了Oracle服务器，又安装了客户端的状况。

 

 

下面是仅仅在一台机器上安装了服务器，而且是在服务器本机上安装PLSQL使用Oracle数据库的状况：

# listener.ora Network Configuration File: E:\oracle\product\10.2.0\db_1\network\admin\listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
    (SID_LIST =
        (SID_DESC =
            (SID_NAME = PLSExtProc)
            (ORACLE_HOME = E:\oracle\product\10.2.0\db_1)
            (PROGRAM = extproc)
        )
        (SID_DESC =                     (GLOBAL_DBNAME = ORCL)                     (ORACLE_HOME = E:\oracle\product\10.2.0\db_1)                             (SID_NAME = ORCL)                 )             ) LISTENER =     (DESCRIPTION_LIST =         (DESCRIPTION =             (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))             (ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))         )     )
