Linux下oracle数据库启动

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)
在这里插入图片描述

3.进入sqlplus界面(命令是:$ sqlplus /nolog 或 sqlplus / as sysdba)
在这里插入图片描述
原本的画面会变为
SQL>
接着请输入

SQL>conn / as sysdba ;
输入

SQL> 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 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 12193 1 0 11:00 ? 00:00:00 ora_pmon_orcl
oracle 12195 1 0 11:00 ? 00:00:00 ora_vktm_orcl

oracle 12201 1 0 11:00 ? 00:00:00 ora_diag_orcl
oracle 12203 1 0 11:00 ? 00:00:00 ora_dbrm_orcl
oracle 12205 1 0 11:00 ? 00:00:00 ora_psp0_orcl
oracle 12207 1 0 11:00 ? 00:00:00 ora_dia0_orcl
oracle 12209 1 0 11:00 ? 00:00:00 ora_mman_orcl
oracle 12211 1 0 11:00 ? 00:00:00 ora_dbw0_orcl
oracle 12213 1 0 11:00 ? 00:00:00 ora_lgwr_orcl
oracle 12215 1 0 11:00 ? 00:00:00 ora_ckpt_orcl
oracle 12217 1 0 11:00 ? 00:00:00 ora_smon_orcl
oracle 12219 1 0 11:00 ? 00:00:00 ora_reco_orcl
oracle 12221 1 0 11:00 ? 00:00:00 ora_mmon_orcl
oracle 12223 1 0 11:00 ? 00:00:00 ora_mmnl_orcl
oracle 12225 1 0 11:00 ? 00:00:00 ora_d000_orcl
oracle 12227 1 0 11:00 ? 00:00:00 ora_s000_orcl
oracle 12239 1 0 11:00 ? 00:00:00 ora_qmnc_orcl
oracle 12257 1 0 11:00 ? 00:00:00 ora_cjq0_orcl
oracle 12277 1 0 11:00 ? 00:00:00 ora_q000_orcl
oracle 12279 1 0 11:00 ? 00:00:00 ora_q001_orcl
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
LSNRCTL for Linux: Version 11.2.0.1.0 - Production on 17-MAR-2022 11:03:33

[oracle@localhost ~]$ ^C
[oracle@localhost ~]$

如果没有启动,可以输入:$ lsnrctl start (作用是:启动监听器)

[oracle@localhost ~]$ lsnrctl start
