Question

我刚开始尝试使用Red Hat Linux 7.2和Oracle 12c。所以我上周末花了很多时间试图看看我是否可以在RHEL 7.2上站起来Oracle 12c。最后，是的，我能够在RHEL 7.2 VM上站起来，但不是没有问题 - 很多。但我设法解决了他们一次一个。我吹走了我的虚拟机，并从头开始重新开始。

现在我觉得我有一个非常好的设置＆amp;运行。我唯一不理解的是当我重新启动Linux机器时，Oracle列表器和数据库服务都不会像在Windows Server 2012 R2系统上那样自动启动。如果这些服务没有运行，我自然无法连接到Oracle DB。要修复它，我必须运行这两个命令：

以oracle用户身份登录
运行lsnrctl start

我会看到类似的消息：监听器不支持任何服务这很好。
连接数据库并运行

SQL＆GT;启动

之后，一切正常运行。我可以从任何Oracle客户端连接到Oracle数据库。我的问题是：这是Linux机箱上的正常行为吗？我在Oracle安装过程中遗漏了什么？如果这些服务应该自动启动，我需要做些什么才能解决这个问题？

谢谢。

Answer 1

您应该检查侦听器日志以获取详细信息。

使用以下命令查找侦听器日志位置：

$file

Answer 2

此错误解决方案非常简单，首先，让我们理解为什么会出现此错误。它基本上有两个原因：

1）您的数据库和服务名称在Oracle环境中没有正确设置它应该在任何地方检查下面的参数值

-ORACLE_SID in oracle environment.
-SID_NAME in tnsnames.ora file.
-SERVICE_NAME in listener.ora file.

2）主机名/ IP地址丢失，不正确或拼写错误，请查看以下内容。

-Check the IP ADDRESS in /etc/hosts file.
-It should be same in listener.ora and tnsnames.ora file
-And it should be able to ping from the local and remote server.

现在看到我也面临同样的问题并解决了：
