上期中创建完数据库实例,但是最后使用em访问数据库实例的时候出现了一个问题?
Enterprise Manager 无法连接到数据库实例。下面列出了组件的状态。
回答上面的问题请看以下oracle的结构:
客户使用浏览器通过EM的1158端口访问EM,EM通过监听访问oracle数据库实例,上节中我们通过数据库配置助手（Database Configuraion Assistant）创建了数据库实例，但我们还没有创建监听.所以就出现了上节最后提出的问题.这节中我们将通过oracle网络配置助手(Oracle Net Configuration Assistant) 完成Listener创建
[[email protected] db_1]$ netca
Oracle Net Configuration Assistant（oracle网络配置助手的第一个页面）监听程序配置 下一步
添加 下一步
下一步
下一步
使用标准端口号1521下一步
否下一步
下一步
配置完监听以后还需要配置 本地Net服务名配置 下一步
下一步
服务名 和数据库的实例名一样 下一步
选择TCP下一步
主机名 本机ip 下一步
不，不进行测试 下一步
网络服务名 数据库实例名 下一步
下一步
下一步
完成
验证配置成功以否:
