一、这个跟国庆前我发表的 dbids 类似,是把数据库作为标准服务
安装到 Linux 的系统脚本。这个也是原创的,与青蛙网友分享。

二、所谓标准系统服务,应该是满足以下几条标准的后台运行程序。
1) 用 chkconfig --add 来安装,用 chkconfig --list 检查状态。
2) 用 ntsysv 来定制某个服务,是否伴随机器的启动而自动启动。
3) 在图形模式下,可以用 serviceconf 来启动、停止、重启服务。
4) 开机象系统服务那样显示 starting,关机显示 shutting down。

三、下面是具体的 dbora 脚本,在 Redhat 7.3 上通过,本人已经
验证了几十次,保证能运行。如果在您的系统不能运行,请告知。

备注:启动 lsnrctl 的时候不用 su- 而使用 su,否则失败,并且
要求使用 oracle 用户本身的 BASH_ENV。脚本开头的几个 ORA_xxx
参数都要依照实际情况写,否则会说找不到 Oracle 程序或者 pid。
DOS 格式方便发文,拷下来后请大家用 UltraEdit 转为 Unix 格式。
