Linux中Oracle服务启动和停止脚本与开机自启动
linux  /  管理员 发布于 6年前   156
在CentOS 6.3下安装完Oracle 10g R2,重开机之后,你会发现Oracle没有自行启动,这是正常的,因为在Linux下安装Oracle的确不会自行启动,必须要自行设定相关参数,首先先介绍一般而言如何启动oracle。
一、在Linux下启动Oracle
登录到CentOS,切换到oracle用户权限
# su C oracle
接着输入:
$ sqlplus "/as sysdba"
原本的画面会变为
SQL>
接着请输入
SQL> startup
就可以正常的启动数据库了。
另外停止数据库的指令如下:
SQL> shutdown immediate
二、检查Oracle DB监听器是否正常
回到终端机模式,输入:
$ lsnrctl status
检查看看监听器是否有启动
如果没有启动,可以输入:
$ lsnrctl start
启动监听器
SQL> conn sys@orcl as sysdba
然后输入密码,sys以sysdba身份登入数据库。
三、启动emctl
另外也可以发现http://localhost.localdomain:1158/em 目前是没有反应的,这边要另外启动,启动的指令如下:
$ emctl start dbconsole
这个指令运行时间较长,执行完的画面如下:
手动启动Oracle数据库完毕,下面创建系统自行启动Oracle的脚本。
四、Oracle启动&停止脚本
1. 修改Oracle系统配置文件:/etc/oratab,只有这样,Oracle 自带的dbstart和dbshut才能够发挥作用。
# vi /etc/orataborcl:/opt/oracle/102:Y# Entries are of the form:# $ORACLE_SID:$ORACLE_HOME:<N|Y>:
2. 在 /etc/init.d/ 下创建文件oracle,内容如下:
#!/bin/sh# chkconfig: 35 80 10# description: Oracle auto start-stop script.## Set ORA_HOME to be equivalent to the $ORACLE_HOME# from which you wish to execute dbstart and dbshut;## Set ORA_OWNER to the user id of the owner of the# Oracle database in ORA_HOME.ORA_HOME=/opt/oracle/102ORA_OWNER=oracleif [ ! -f $ORA_HOME/bin/dbstart ]then echo "Oracle startup: cannot start" exitficase "$1" in'start')# Start the Oracle databases:echo "Starting Oracle Databases ... "echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Starting Oracle Databases as part of system up." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oraclesu - $ORA_OWNER -c "$ORA_HOME/bin/dbstart" >>/var/log/oracleecho "Done"# Start the Listener:echo "Starting Oracle Listeners ... "echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Starting Oracle Listeners as part of system up." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oraclesu - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start" >>/var/log/oracleecho "Done."echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Finished." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oracletouch /var/lock/subsys/oracle;;'stop')# Stop the Oracle Listener:echo "Stoping Oracle Listeners ... "echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Stoping Oracle Listener as part of system down." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oraclesu - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop" >>/var/log/oracleecho "Done."rm -f /var/lock/subsys/oracle# Stop the Oracle Database:echo "Stoping Oracle Databases ... "echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Stoping Oracle Databases as part of system down." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oraclesu - $ORA_OWNER -c "$ORA_HOME/bin/dbshut" >>/var/log/oracleecho "Done."echo ""echo "-------------------------------------------------" >> /var/log/oracledate +" %T %a %D : Finished." >> /var/log/oracleecho "-------------------------------------------------" >> /var/log/oracle;;'restart')$0 stop$0 start;;esac
3. 改变文件权限
# chmod 755 /etc/init.d/oracle
4. 添加服务
# chkconfig --level 35 oracle on
5. 需要在关机或重启机器之前停止数据库,做一下操作
# ln -s /etc/init.d/oracle /etc/rc0.d/K01oracle //关机# ln -s /etc/init.d/oracle /etc/rc6.d/K01oracle //重启
6. 使用方法
# service oracle start //启动oracle # service oracle stop //关闭oracle # service oracle restart //重启oracle
7. 测试
a. 开机自启动
