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sqlplus界面(命令是:$ sqlplus /nolog 或 sqlplus / as sysdba)输入:$ lsnrctl 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> 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。
一、在Linux下启动Oracle
1.登录到Linux服务器(ssh)
2.切换到oracle用户权限
(命令是:# su –l oracle)
3.进入sqlplus界面(命令是:$ sqlplus /nolog 或 sqlplus / as sysdba)
原本的画面会变为
SQL>
接着请输入
另外停止数据库的指令如下:
SQL> shutdown immediate
二、检查Oracle 数据库是否启动
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。)
[oracle@localhost ~]$ ps -ef|grep ora_

oracle 12389 10058 0 11:01 pts/0 00:00:00 grep --color=auto ora_
[oracle@localhost ~]$
三、检查Oracle DB监听器是否正常
输入:$ lsnrctl status (作用是:检查监听是否启动。) 以下为没有启动。
[oracle@localhost ~]$ lsnrctl status
