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



Linux下启动/关闭Oracle_监听器

[oracle@localhost ~]$ sqlplus /nolog

切换用户:

4.通过startup命令启动实例



Linux下启动/关闭Oracle_监听器

SQL> startup
