Oracle11g 两个oracle数据库之间的数据库链接问题（Ora-12541:“TNS:无侦听器”）

我是甲骨文的新手，所以我很抱歉这个可能是琐碎或愚蠢的问题。我需要通过这样的数据库链接互连两个oracle数据库（12g和11g）：

创建共享数据库链接系统
由scot认证，由*********
使用“SYSEL”

ORCL =

SYSEL =

  (ADDRESS = (PROTOCOL = TCP)(HOST = Panoramix)(PORT = 1524))

但是如果我运行一个查询（例如

select*fromdual@sysel

），我总是会遇到以下错误： ORA-12541:TNS:neexistuježádnýproces监听器 1254100000-“TNS：没有侦听器” *原因：无法完成连接请求，因为侦听器 他没有跑步。 *措施：确保提供的目标地址与以下地址之一匹配： 侦听器使用的地址-将TNSNAMES.ORA条目与 适当的LISTENER.ORA文件（如果要连接，则为TNSNAV.ORA） 走立交桥）。在远程计算机上启动侦听器。 第1行第20列出错

我在panoramix上有一个特技（它完全可以工作，我可以通过sql developer连接到studuk，也可以tnsping studuk。但是数据库链接不起作用。我想，可能需要修改listener.ora的某些方式，但我不知道如何。。。 有什么问题吗？请帮忙。 祝你一切顺利 约瑟夫K

现在侦听器在端口1521上侦听，但尝试以select*from的形式运行查询dual@sysel我不幸地发现了这个错误：

    ORA-12514: TNS:proces listener v současnosti nezná službu požadovanou v deskriptoru připojení
   12514. 00000 -  "TNS:listener does not currently know of service requested in connect    descriptor"
  *Cause:    The listener received a request to establish a connection to a
       database or other service. The connect descriptor received by the listener
       specified a service name for a service (usually a database service)
         that either has not yet dynamically registered with the listener or has
       not been statically configured for the listener.  This may be a temporary
       condition such as after the listener has started, but before the database
       instance has registered with the listener.
 *Action:   
       - Wait a moment and try to connect a second time.
       - Check which services are currently known by the listener by executing:
       lsnrctl services <listener name>
       - Check that the SERVICE_NAME parameter in the connect descriptor of the
       net service name used specifies a service known by the listener.
       - If an easy connect naming connect identifier was used, check that
       the service name specified is a service known by the listener.
       - Check for an event in the listener.log file.

显然，我的Oracle实例无法向侦听器注册服务SYSEL，我也尝试了ALTER SYSTEM register，但没有成功

剧本

select value from v$parameter where name='service_names' 

仅返回默认值“ORCL”

我应该如何向侦听器注册服务SYSEL？ 非常感谢。

您启动了两个侦听器进程吗？一个运行在端口1521上，另一个运行在端口1524上？感谢您的回答，不，我没有，我只有端口1524上的侦听器。因此我尝试配置侦听器。侦听器=（DESCRIPTION_LIST=（DESCRIPTION=（ADDRESS=（PROTOCOL=IPC）（KEY=EXTPROC1524））（ADDRESS=（PROTOCOL=TCP）（HOST=Panoramix）（PORT=1524））（ADDRESS=（PROTOCOL=TCP）（HOST=Panoramix）（PORT=1521）））这是对的吗？最好的Josef K。
