ORA 12514错误：TNS监听器错误

确定一切正常，直到昨日现在我突然收到此错误
ORA-12514：TNS：监听器目前不知道在连接描述符
没有请求的服务已被修改ORA 12514错误：TNS监听器错误

XE = 
    (DESCRIPTION = 
(ADDRESS = (PROTOCOL = TCP)(HOST = jainam-2b1c493d)(PORT = 1521)) 
(CONNECT_DATA = 
    (SERVER = DEDICATED) 
    (SERVICE_NAME = XE) 
) 
) 

EXTPROC_CONNECTION_DATA = 
    (DESCRIPTION = 
    (ADDRESS_LIST = 
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) 
    ) 
    (CONNECT_DATA = 
     (SID = PLSExtProc) 
     (PRESENTATION = RO) 
    ) 
) 

    ORACLR_CONNECTION_DATA = 
     (DESCRIPTION = 
    (ADDRESS_LIST = 
    (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)) 
    ) 
    (CONNECT_DATA = 
    (SID = CLRExtProc) 
    (PRESENTATION = RO) 
) 
)

我完全卡住了，不知道该怎么做。我从这里试过帮助
http://dba-oracle.com/t_ora_12514_tns_listener_does_not_currently_know_service_requested.htm 但没用。感谢

编辑：
这里的输出lsnrctl service

我不是这个错误的专家，但战斗有点。你确定运行oracle的机器仍然可以到达主机吗？ –

你可以在命令行尝试'tnsping [yourconnection]'，看看它说什么吗？ – Deruijter

@Deruijter yes tnsping 127.0.0.1是否能够连接 –

其中一个原因你那种错误的，因为听者之前做过数据库实例启动。听众必须始终先启动。

检查数据库实例启动并运行
检查lsnrctl service命令的输出，看服务注册的。
检查连接到实例时是否正确指定了SERVICE_NAME。
如果数据库实例发生在侦听器之前，有时您只需稍等一下，或者您可以执行alter system register以注册实例。

检查编辑请... –

@ user1461078检查什么？你什么意思？ –

'lsnrctl service'的输出并查看是否有错误。 –

对我来说帮助下SID_DESC添加到C：\ oraclexe \程序\ ORACLE \产品\ 11.2.0 \服务器\网络\ ADMIN \ listener.ora中

SID_LIST_LISTENER = 
    (SID_LIST = 
    ... 
    (SID_DESC = 
     (SID_NAME = XE) 
     (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server) 
    ) 
)

重新启动后监听器和数据库的访问再次工作。

当一切都失败时，这应该对我有用。 – tjeloep

也为我工作。 –

打开SQL Plus并连接到系统用户：

system/[email protected]

并运行两个命令：

SQL> alter system set LOCAL_LISTENER='(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521))' scope=both; 
SQL> alter system register;
