Linux 下Oracle 开机自启动与 oratab， dbstart 脚本说明

一./etc/oratab说明

直接使用cat 查看这个文件：

这里是我测试环境上的文件，在这个注释里面，对这个文件讲的比较清楚。/etc/oratab 由root.sh 脚本创建，在用DBCA 创建实例时也会更新这个文件。

当$ORACLE_SID:$ORACLE_HOME: 设置为Y时，允许实例自启动，当设置为N时，则不允许自启动。这个文件里的配置仅仅起一个开关的作用，，其并不会具体的执行启动和关闭，具体的操作由$ORACLE_HOME/bin/dbstart和dbshut 脚本来实现。这2个脚本在执行时会检查/etc/oratab 文件里的配置，为Y时才能继续执行。

所以配置数据库自启动和关闭的步骤如下：

（1）配置/etc/oratab

（2）修改$ORACLE_HOME/bin/dbstart和dbshut，并将其添加到/etc/rc(.local) 文件中。

这里是使用oracle 自带的dbstart 和dbshut脚本，如果使用自己写的脚本来启动或关闭DB 就不需要关心这个文件的设置了。
