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


2.关闭监听器


[oracle@localhost ~]$ lsnrctl stop
