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
