Linux下oracle数据库启动_代码007(未授权)

本文介绍: 回到终端机模式，输入：ps –ef|grep ora _ (作用是：查看是否有Oracle的进程,如果有,大多数情况说明启动了。3.进入 sql plus 界面(命令是：$ sql plus /no log 或 sqlplus / a s sys dba)输入：$ lsn r ctl status (作用是：检查监听是否启动。如果没有启动，可以输入：$ lsnrctl start (作用是：启动监听器)SQL&g t; startup (作用：启动数据库实例)1.登录到Linux 服务器（ssh）2.切换到oracle 用户权限。

1.登录到Linux 服务器（ssh）
2.切换到oracle 用户权限
(命令是：# su –l oracle)
在这里插入图片描述

3.进入 sqlplus 界面(命令是：$ sqlplus /no log 或 sqlplus / as sys dba)
在这里插入图片描述
原本的画面会变为
SQL&g t;
接着请输入

SQL&g t;conn / as sys dba ;
输入

SQL&g t; startup (作用：启动数据库实例)

在这里插入图片描述

另外停止数据库的指令如下：
SQL> shutdown i m mediate
