Question

我已经配置了以下两个oracle数据库的配置文件。

/opt/oracle/11.2.0/network/admin/listener.ora有以下值

ADR_BASE_LISTENER = /opt/oracle



LISTENER_JIPDB =
  (DESCRIPTION_LIST =
          (DESCRIPTION =
                (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1530))
          )
  )

SID_LIST_LSNR_JIPDB =
  (SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME = DWJP02T)
      (ORACLE_HOME = /opt/oracle/11.2.0)
      (SID_NAME = DWJP02T)
    )
  )

我配置了/opt/oracle/11.2.0/network/admin/tnsnames.ora 文件具有以下值

LISTENER_JIPDB =
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain )(PORT = 1530))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = DWJP02T)
    )
  )

我的问题是当我尝试通过输入以下命令启动oracle listner时，它在1521端口打开DWJP02T SID实例，我不知道它是如何获取此端口或从它读取此端口的位置，我已配置为在.ora文件上读取1530。

这是我启动列表器时得到的输出

[ora112@localhost ~]$ lsnrctl start

请帮助我理解为什么它在不同的端口上打开数据库，而不是我开始配置它。我重新启动了数据库和服务器，看它是否会读取listner.ora文件中的值，但仍然没有运气。

尝试以下步骤提供请求：

使用以下命令停止Oracle侦听器：
```
lsnrctl stop
```
更改Oracle listener.ora文件中的端口号。例如，从默认端口1522到1521。
更改tnsnames.ora文件中的端口号，如下例所示，其中host_name是您的主机名，server_name是您的服务器名称。
使用以下命令重新启动Oracle侦听器：
```
lsnrctl start
```

更改数据库正在侦听的端口：

sqlplus / as sysdba        
> alter system set LOCAL_LISTENER="(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1522))";        
> alter system register;

在侦听器启动期间不会读取Oracle数据库listener.ora配置
