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

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
