“ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务”问题的解决
1. 打开文件"<OracleHome>/network/admin/listener.ora" ,你将看到如下的内容:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
)
2. 将下面的语句添加到上面的语句中去(红色部分改成自己的东西)。
(SID_DESC =
(GLOBAL_DBNAME = ORACLE)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_NAME = ORACLE)
)
3. 文件的内容则变成了如下所示:
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = ORACLE)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_NAME = ORACLE)
)
)
4. 保存文件,然后重新启动监听服务TNSListener就可以了 !
