一、Linux下启动Oracle

  Linux下启动Oracle分为两步:

  1)启动监听;

  2)启动数据库实例;

 

1.登录服务器,切换到oracle用户,或者以oracle用户登录

[admin@dataserver ~]$ su - oracle
密码:
[oracle@dataserver ~]$

2.打开监听服务

[oracle@localhost ~]$ lsnrctl start

可以通过lsnrctl status命令查看Oracle监听器运行状况

[oracle@localhost ~]$ lsnrctl status

3.以SYS用户身份登录Oracle

 

[oracle@localhost ~]$ sqlplus /nolog

SQL*Plus: Release 11.2.0.1.0 Production on Fri Dec 1 23:29:19 2017

Copyright (c) 1982, 2009, Oracle.  All rights reserved.

SQL> conn /as sysdba
Connected to an idle instance.

 

切换用户:

CONN 用户名/密码 [AS SYSDBA],如果是sys用户一定要写上AS SYSDBA

4.通过startup命令启动实例

 

SQL> startup
ORACLE instance started.

Total System 
... ...
Database mounted.
Database opened.
SQL>

 

二、Linux下关闭Oracle

1.关闭数据库实例

 

SQL> shutdown
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> quit
Disconnected from Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production

2.关闭监听器

[oracle@localhost ~]$ lsnrctl stop
