I installed Oracle10g today.I tested the database system when the installation process was finished. I found that I could not connect the database by  
using iSQL\*Plus. It showed that "ERROR - ORA-12514: TNS: 监听程序当前无法识别连接描述符中请求的服务".

解决办法：

1. Open the ""<OracleHome>/network/admin/listener.ora" file in the host,and you will see:  
SID\_LIST\_LISTENER =  
(SID\_LIST =  
(SID\_DESC =  
(SID\_NAME = PLSExtProc)  
(ORACLE\_HOME = D:/oracle/product/10.2.0/db\_1)  
(PROGRAM = extproc)  
)  
)  
2. Add the following lines after the 7th line in the above  
(SID\_DESC =  
(GLOBAL\_DBNAME = ORACLE)  
(ORACLE\_HOME = D:/oracle/product/10.2.0/db\_1)  
(SID\_NAME = ORACLE)  
)  
3. At last the content of the file become to the following section:  
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. Save the file and restart the TNSListener service in the host. That's OK!
