使刚才配置的.bash_profile文件内容生效。

以上是创建的逻辑卷和裸设备。用lvscan查看逻辑卷，用raw -qa 查看当前的裸设备。
具体裸设别的创建步骤是：用pvcreate /dev/sda11 /dev/sda12 ...... 创建物理卷，用 vgcreate
oradata /dev/sda11 /dev/sda12 ...... 创建逻辑卷组，用lvcreate --size 1000m --name nms_hypr01
/dev/oradata 分配逻辑卷，用raw /dev/raw/raw20 /dev/mapper/oradata-nms_hypr01 创建裸设备。
呵呵，别忘了给逻辑卷和裸设备更改所有者哦！Chown -R oracle.dba /dev/raw/* chown -R
oracle.dba /dev/mapper/oradata* 。另外还要注意的是裸设备raw在每次重启reboot的时候需
要重建，为了简单让其在启动后自动创建，我们可以写个简单的脚本SHELL让它自动执行
就可以了。我在/var/opt/oracle/目录下建立了两个SHELL

[root@RHAS4 oracle]# ls -l /var/opt/oracle/
