1.1 ss初始化及启动
--->1节点：
cd /dm/bin
./dmdssinit path=http://www.likecs.com/dm/data inst=ss1 port=35300 REGION_SIZE=2 DBF_SIZE=10240 RLOG_SIZE=128
./dmdss path=http://www.likecs.com/dm/data/SS1/dss.ini

1.2 DCS 初始化及启动
1.2.1 后台库DCS_DB初始化及原始数据构造
cd /dm/bin
./dminit path=http://www.likecs.com/dm/data db_name=dcs_db instance_name=DCS_DB port_num=35200
./dmserver /dm/data/dcs_db/dm.ini
./disql SYSDBA/SYSDBA@192.168.0.152:35200
>SP_DFS_DCS_INIT(1); ---默认DSC端口3333
1.2.2启动DCS并添加FD和SS
创建dcs.key
./dmdcs -init=1 USER=SYSDBA PASSWORD=SYSDBA PATH=dcs.key
启动dcs
./dcsserver server=192.168.0.152:35200
启动dmdcstool
./dmdcstool host=192.168.0.152 port_num=3333
>add micro fault domain fd1
>add micro fault domain fd2
>add micro fault domain fd3
>add micro storage server SS1 ('192.168.0.153':35300) in fd1
>add micro storage server SS1 ('192.168.0.153':35300) in fd2
>add micro storage server SS1 ('192.168.0.153':35300) in fd2
>alter storage server refresh size
>alter storage server open ---添加ss 。dmdcstool必须连接DCS，不是RS
1.3 添加组和RS
dmdcstool 执行：
>add group grp1
>add rlog server "DRS" ('192.168.0.152':3332) group grp1 --- rs与组一一对应；多rs建立多个组即可
1.4 启动RS
配置drs.ini到/dm/data
启动RS：
./dmdrs path=http://www.likecs.com/dm/data/drs.ini
1.5 搭建两节点rac
1.5.1 配置dmdcr_cfg.ini
1.5.2配置dmdfs.ini
1.5.3 使用dmasmcmd初始化
./dmasm dfs_ini=http://www.likecs.com/dm/data/dsc/dmdfs.ini
>create emptyfile '/dm/data/asmdisks/dcr.asm' size 32
>create emptyfile '/dm/data/asmdisks/vtd.asm' size 32
>create dcrdisk '/dm/data/asmdisks/dcr.asm' 'dcr' 32
>create votedisk '/dm/data/asmdisks/vtd.asm' 'vtd' 32
>init dcrdisk '/dm/data/asmdisks/dcr.asm' from '/dm/data/dsc/dmdcr_cfg.ini' identified by 'hust4400'
>init votedisk '/dm/data/asmdisks/vtd.asm' from 'dm/data/dsc/dmdcr_cfg.ini'
>init ddfsdcr '$/dameng/dsc/asmdisks/dcr.asm' from '/dm/data/asmdisks/dcr.asm'
>init ddfsvtd '$/dameng/dsc/asmdisks/vtd.asm' from '/dm/data/asmdisks/vtd.asm'
1.5.4 准备 dminit.ini
保存到/dm/data/dsc/目录下
1.5.5 初始化库
/dminit control=http://www.likecs.com/dm/data/dsc/dminit.ini
1.5.6 向DMTDD添加前段数据库
启动dmdcstool 连接DCS
./dmdcstool host=192.168.0.152 port_num=3333
>add data server dsc0 group grp1 database db_dsc arch_dir '/dm/data/arch_dsc0'
>add data server dsc1 group grp1 database db_dsc arch_dir '/dm/data/arch_dsc1' ---必须连接DCS 不是DRS；
1.5.7 配置dmdcr.ini
DSC0 节点的dmdcr0.ini 保存在/dm/data/dsc
DSC1 节点的dmdcr1.ini 保存在/dm/data/dsc
1.5.8 启动CSS
启动CSS0
./dmcss dcr_ini=http://www.likecs.com/dm/data/dsc/dmdcr0.ini dfs_ini=http://www.likecs.com/dm/data/dsc/dmdfs.ini
启动CSS1
./dmcss dcr_ini=http://www.likecs.com/dm/data/dsc/dmdcr1.ini dfs_ini=http://www.likecs.com/dm/data/dsc/dmdfs.ini
1.5.9 启动dsc节点
./dmserver /dm/data/dsc/dsc0/dm.ini dcr_ini=http://www.likecs.com/dm/data/dsc/dmdcr0.ini
./dmserver /dm/data/dsc/dsc1/dm.ini dcr_ini=http://www.likecs.com/dm/data/dsc/dmdcr1.ini
