DG与ASM File的空间分配
本节针对中小容量阵列进行空间规划举例，产品依据实际情况进行调整。
【基本原则】
l dg_ora最大不超过150G；
l dg_data与dg_index的比例为1:1
l dg_backup与dg_data或dg_index之间的比例应在1:2~1:4之间，建议为1:3。
l DG命名规则、DG用途、ASM File命名规则、ASM File用途、ASM File大小依据本章的规划进行设置。
DG_ORA空间划分示例：
100G的DG_ORA划分 |
DG名称 |
ASM File名称 | ASM File大小(MB) | 用途 |
DG_ORA [分配20.65G] | system | 3000 | 创建system表空间 |
sysaux | 3000 | 创建sysaux表空间 |
temp | 4000 | 创建temp表空间 |
undotbs01 | 4000 | 创建undo表空间 |
user | 50 | 创建user表空间 |
control01 | 300 | 创建控制文件 |
control02 | 300 | 创建控制文件 |
redolog01 | 2000 | 创建联机日志1号组成员 |
redolog02 | 2000 | 创建联机日志2号组成员 |
redolog03 | 2000 | 创建联机日志3号组成员 |
剩下的空间可以分配给应用表空间，或应用表空间使用独立的ASM磁盘组下的某个成员（这时，应减少DG_ORA对应lun的大小分配）。
根据本章节整理的共享磁盘与盘符的对应关系，以root用户登录，编辑/etc/init.d/after.local添加以下记录（如果存在则跳过）：
mkdir -p /dev/diskgroup
chmod 770 /dev/diskgroup
chown grid:oinstall /dev/diskgroup
ln -f -s /dev/disk/by-id/scsi-360022a110003135e2d632e9f00000000/dev/diskgroup/dg_ora
chmod 660 /dev/diskgroup/dg_*
chown grid:oinstall /dev/diskgroup/dg_*
对/etc/init.d/after.local赋权限
# chmod 744 /etc/init.d/after.local
执行/etc/init.d/after.local
# sh /etc/init.d/after.local
配置HAS
以root用户登录服务器，执行脚本roothas.pl
#/opt/oracrs/product/11gR2/grid/perl/bin/perl -I/opt/oracrs/product/11gR2/grid/perl/lib -I/opt/oracrs/product/11gR2/grid/crs/install /opt/oracrs/product/11gR2/grid/crs/install/roothas.pl
下面是执行过程中的屏显信息
