在OS启动时，可以设置oracle和os一起启动或关闭。oracle自带dbstart和dbshut命令。它们会读取oratab文件

[oracle@prod1 bin]$ cd $ORACLE_HOME/bin
#查看启动和关闭脚本是否存在
[oracle@prod1 bin]$ ls dbstart 
dbstart
[oracle@prod1 bin]$ ls dbshut 
dbshut

修改dbstart、dbshut命令

[oracle@prod1 bin]$ vi dbstart 
ORACLE_HOME_LISTNER=$ORACLE_HOME
[oracle@prod1 bin]$ vi dbshut 
ORACLE_HOME_LISTNER=$ORACLE_HOME

修改oratab文件
PROD为ORACLE_SID
/u01/app/oracle/product/11.2.0/db_1为ORACLE_HOME
Y表示允许数据库自动启动或关闭

[oracle@prod1 bin]$ vi /etc/oratab 
PROD:/u01/app/oracle/product/11.2.0/db_1:Y

验证

[oracle@prod1 admin]$ dbstart
Processing Database instance "PROD": log file /u01/app/oracle/product/11.2.0/db_1/startup.log
[oracle@prod1 admin]$ more /u01/app/oracle/product/11.2.0/db_1/startup.log

esac 

修改文件权限

[root@prod1 init.d]# chmod 755 oracle

添加服务

[root@prod1 init.d]# chkconfig --level 35 oracle on

关机或重启自动关闭

[root@prod1 rc0.d]# ln -s /etc/rc.d/init.d/oracle /etc/rc0.d/K01oracle
[root@prod1 rc0.d]# ln -s /etc/rc.d/init.d/oracle /etc/rc6.d/K01oracle

使用

service oracle start
service oracle stop
service oracle restart
