oracle – TNS-12541错误
作者：互联网
我在我的电脑上安装了网格,但问题是LISTENER无法自动启动.我必须手动启动监听器,然后只启动LISTENER.但是在启动监听器之前如果先检查状态,那么如果您尝试LSNRCTL状态,则会显示以下内容.我遵循了以下网址,但它对我不起作用：
Linux Error: 111: Connection refused LSNRCTL
我的问题是如何让监听器自动运行？
请检查以下所需的必要信息： –
[grid@netsystemsolution ~]$lsnrctl status
LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 01-JAN-2015 12:01:56

如果你从crvctl检查监听器的状态,那么这就是它显示的内容：
[grid@netsystemsolution ~]$srvctl status listener

[grid@netsystemsolution ~]$srvctl config listener

我按照以下url进行了listener.ora,sqlnet.ora和tnsnames.ora配置

现在我用lsnrcrl命令手动启动监听器,这是它显示的内容：

启动监听器之后,lsnrctl再次启动…如果你需要查看1521是否正在运行,那么这里是：
[grid@netsystemsolution admin]$netstat -nltp

我想知道问题出在哪里？为什么我必须手动启动监听器？为什么监听器不会自动启动？请建议.
解决方法:
在Oracle Grid Infrastructure中注册监听器的最简单方法是运行netca.如果要配置侦听器“LISTENER”,则必须确保它在listener.ora中不存在.
还有一件事：您应该始终在/ etc / hosts文件中配置自己的主机.
