VMware虚拟机搭建Linux Oracle 10g ASM环境，ASM实例已经启动，这个时候我们就可以用DBCA来创建数据库了，唯一需要注意的是在选择
1.新增磁盘进行分区
这里我们将新增磁盘分成3部分：/dev/sdb1,/dev/sdb2,/dev/sdb3
[root@ocp db10g]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
