DM TDD使用小结

1.搭建流程

1.1 ss初始化及启动

--->1节点：

cd /dm/bin

./dmdssinit path=/dm/data inst=ss1 port=35300 REGION_SIZE=2 DBF_SIZE=10240 RLOG_SIZE=128

./dmdss path=/dm/data/SS1/dss.ini

--->2节点：

。。。

--->3节点：

。。。

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=/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=/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=/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=/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=/dm/data/dsc/dmdcr0.ini dfs_ini=/dm/data/dsc/dmdfs.ini

启动CSS1

./dmcss dcr_ini=/dm/data/dsc/dmdcr1.ini dfs_ini=/dm/data/dsc/dmdfs.ini

1.5.9 启动dsc节点

./dmserver /dm/data/dsc/dsc0/dm.ini dcr_ini=/dm/data/dsc/dmdcr0.ini

./dmserver /dm/data/dsc/dsc1/dm.ini dcr_ini=/dm/data/dsc/dmdcr1.ini
