1 建立文件/etc/init.d/oracle内容后。
2 使这一文件可以执行   chmod a+x /etc/init.d/oracle
3 测试/etc/init.d/oracle start和/etc/init.d/oracle可以正常启动和关闭数据库
4 建立联结
        ln -s /etc/init.d/oracle /etc/rc3.d/S95oracle
        ln -s /etc/init.d/oracle /etc/rc5.d/S95oracle
        ln -s /etc/init.d/oracle /etc/rc0.d/K05oracle
        ln -s /etc/init.d/oracle /etc/rc1.d/K05oracle
        ln -s /etc/init.d/oracle /etc/rc2.d/K05oracle
        ln -s /etc/init.d/oracle /etc/rc4.d/K05oracle
        ln -s /etc/init.d/oracle /etc/rc6.d/K05oracle

这样在系统启动时将可以自动启动数据库，系统关闭时将自动关闭数据库
可以通过数据库的alert文件确认。
