Oracle 重新启动服务器后出现ORA-12514错误
我在服务器上安装了oracle 11g,.Net oracle客户端将访问数据库。Oracle 重新启动服务器后出现ORA-12514错误,oracle,oracle11g,tnsnames,Oracle,Oracle11g,Tnsnames,我在服务器上安装了oracle 11g,.Net oracle客户端将访问数据库。 直到昨天,我还在使用以下连接字符串从客户端进行连接: 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

直到昨天,我还能够在同一个客户机上使用Oracle SQL Developer。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。

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状态
不显示orcl的状态??我试着启动orcl服务。但是它的说法已经开始了。
可能有什么问题?从评论中可以看出,可能是试图使用新网络适配器的动态IP,因此它使用的地址与侦听器使用的地址不同。解决此问题的最简单方法可能是手动设置该参数:
alter system set local_listener = '(ADDRESS=(PROTOCOL=TCP)(HOST=172.17.26.7)(PORT=1521))' scope=memory;
alter system register;
或者我认为您可以使用较短的版本,但我现在无法验证:
alter system set local_listener = '172.17.26.7:1521' scope=memory;
alter system register;
如果这样做有效-也就是说,lsnrctl服务
现在显示orcl
-并且您对此满意,请将内存
更改为两个
,然后重新执行,以便在下一次数据库重启期间保持
另一个版本是在
tnsnames.ora
中定义侦听器,然后将该别名用于本地\u侦听器
值;如果静态IP曾经发生过更改,这可能会使更改变得更容易,因为您只需要更改listener.ora
和tnsnames.ora
(当然还有您的所有客户机),就不必直接修改DB参数。这可能只有在不同的人管理数据库和那些文件时才有用,这不太可能;但是可能会更整洁一些。如果您可以通过SQL*连接,并且数据库已经启动,并且应该已经注册,即使它在侦听器之前启动;但是,您可以通过更改系统寄存器
强制执行该操作。试试看lsnrctl
现在是否显示服务。如果没有,您的local_listener
参数设置为什么?@AlexPoole我尝试了lsnrctl。。这不是orcl服务。在local_listener中,“value”列中没有值。我们需要设置它吗;服务器名称是否仍解析为172.17.26.7
?(如果查看日志文件,e:\app\administrator\diag\tnslsnr\cplas3\listener\aler t\log.xml
,您可能会看到它试图使用的服务器名称)。您可以将其设置为使用IP地址,但这不是必需的。我假设IP是静态的,不是由DHCP分配的?实际上,当它以前工作时,IP是静态的。但在早上重新启动之前,我们试图在动态ip中配置另一个网络适配器以用于其他目的。从那时起,它只是在给问题。现在我该怎么办?我已经试过了第一个命令。它现在运转良好。我是否需要运行alter system set local_listener='(地址=(协议=TCP)(主机=172.17.26.7)(端口=1521))'范围=两者;这有什么用?它让它持续下去。运行scope=memory
版本时,它只影响正在运行的实例。当数据库重新启动时,它将忘记这一点,并返回spfile
获取其参数。如果执行scope=both
(或者此时执行scope=spfile
),则它也会将更改的参数写入spfile
;因此,下次重新启动时,它仍将使用该设置。
