Linux下启动/关闭Oracle

Linux下启动/关闭Oracle

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、切换用户

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  
With the Partitioning, OLAP, Data Mining and Real Application Testing options

2.关闭监听器

[oracle@localhost ~]$ lsnrctl stop
