一、在SUSE11下手动启动Oracle
登录到suse11，切换到oracle用户权限
# su – oracle
接着输入：
$ sqlplus / as sysdba
继续输入：
SQL> startup
启动成功，如图所示：
停止命令，如下所示：
立即关闭，工作状态会回滚到一致状态：SQL> shutdown immediate；
等待用户完成工作后关闭：SQL>shutdowm normal;
强制关闭，下次重启要回滚日志：SQL>shutdown abort；
二、Oracle DB手动启动监听器
输入命令：
$ lsnrctl status
如图所示：
如果没有启动，可以输入：
$ lsnrctl start
手动启动Oracle数据库完毕，下面创建系统自行启动Oracle的脚本。
三、Oracle自启脚本
1. root用户下创建并编辑文件：/etc/oratab，使Oracle 自带的dbstart发挥作用。
输入命令：
# vim /etc/oratab
编辑内容：AMFEDB:/u01/oracle:Y
此内容路径可根据自身Oracle安装生成的oratab文件复制过来，查找方式如下图所示：
2. 在 /etc/init.d/ 下创建文件oracle，内容如下：
#!/bin/sh
#数据库所在路径
ORA_HOME=/opt/oracle/#oracle用户
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
# 启动实例:
echo "Starting Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Starting Oracle Databases as part of system up." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/dbstart" >>/var/log/oracle
echo "Done"# 启动监听:
echo "Starting Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Starting Oracle Listeners as part of system up." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start" >>/var/log/oracle
echo "Done."
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Finished." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
touch /var/lock/subsys/oracle
;;'stop')
# 关闭监听:
echo "Stoping Oracle Listeners ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Stoping Oracle Listener as part of system down." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop" >>/var/log/oracle
echo "Done."
rm -f /var/lock/subsys/oracle# 关闭实例:
echo "Stoping Oracle Databases ... "
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Stoping Oracle Databases as part of system down." >> /var/log/oracle
echo "-------------------------------------------------" >> /var/log/oracle
su - $ORA_OWNER -c "$ORA_HOME/bin/dbshut" >>/var/log/oracle
echo "Done."
echo ""
echo "-------------------------------------------------" >> /var/log/oracle
date +" %T %a %D : Finished." >> /var/log/oracle
echo "-------------------------------------------------" >> /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. 如果需要在关机或重启机器之前停止数据库执行如下命令
# ln -s /etc/init.d/oracle /etc/rc.d/rc0.d/K01oracle //关机
# ln -s /etc/init.d/oracle /etc/rc.d/rc6.d/K01oracle //重启
6. 测试脚本创建成功
# service oracle start //脚本启动oracle
# service oracle stop //脚本关闭oracle
# service oracle restart //脚本重启oracle
执行脚本无异常，即可重启系统实现Oracle自启动，如图所示：
