重新启动服务器后ORA-12514错误

Question

我在服务器上安装了oracle 11g，而.Net oracle客户端将访问数据库。
直到昨天我从使用该连接字符串连接的客户端：

User ID=dbcplas;Password=pwd123;Data Source=(DESCRIPTION = (ADDRESS =(PROTOCOL = TCP)(HOST = 172.17.26.7)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl.cplas3.com))) 

直到昨天我才得以使用的Oracle SQL Developer在同一个客户端。
今天早上我们重新启动了服务器进行维护。重新启动服务器后，我无法从客户端.Net应用程序或sqldeveloper登录。
我可以通过服务器系统的sql plus登录。
除此之外，我无法通过任何其他方式登录。
服务器端sql-developer也无法正常工作。
我已经在下面提供从服务器的详细信息：

错误：
来自.Net应用程序：
ORA-12514 TNS：侦听器当前不知道连接描述符中的服务请求。

为什么lsnrctl status没有显示orcl的状态？
我试过启动orcl服务。但其说法已经开始..
可能是什么问题？

Answer 1

从注释看来，default local_listener parameter可能尝试使用来自新网络适配器的动态IP，因此它不使用侦听器使用的相同地址。解决这个问题的最简单的方法可能是手动设置参数：

alter system set local_listener = '(ADDRESS=(PROTOCOL=TCP)(HOST=172.17.26.7)(PORT=1521))' scope=memory; 
alter system register; 

或者我认为你可以使用一个较短的版本，但我不能确认现在：

alter system set local_listener = '172.17.26.7:1521' scope=memory; 
alter system register; 

如果作品 - 即lsnrctl services现在显示orcl - 并且您对此感到满意，请将memory更改为both并重新执行，以便在下一次数据库重新启动时持续存在。

这个的另一个版本是定义tnsnames.ora中的侦听器，然后使用该别名作为local_listener值;如果静态IP发生更改，那么可能会更容易进行更改，因为只需更改listener.ora和tnsnames.ora（以及当然所有客户端），则不必直接修改数据库参数。如果你有不同的人管理数据库和这些文件，这可能只是有用的，这不太可能;但可能有点整洁。
