1.搭建DSC

1.1 创建dmdcr_cfg.ini

A机器、B机器配置相同
[dmdba@~]# vi /opt/dsc/config/dmdcr_cfg.ini
DCR_N_GRP = 3 #集群环境有多少个GROUP，范围:1~16
DCR_VTD_PATH = /dev/raw/raw2
DCR_OGUID = 45331

[GRP] #新建一个GROUP
DCR_GRP_TYPE = CSS #组类型（CSS/ASM/DB）
DCR_GRP_NAME = GRP_CSS #组名
DCR_GRP_N_EP = 2 #组内节点个数
DCR_GRP_DSKCHK_CNT = 60 #磁盘心跳容错时间，单位:秒
[GRP_CSS]
DCR_EP_NAME = CSS0 #CSS节点名
DCR_EP_HOST =192.168.1.1 #心跳地址
DCR_EP_PORT = 5336 #CSS端口
[GRP_CSS]
DCR_EP_NAME = CSS1
DCR_EP_HOST =192.168.1.2
DCR_EP_PORT = 5337

[GRP]
DCR_GRP_TYPE = ASM
DCR_GRP_NAME = GRP_ASM
DCR_GRP_N_EP = 2
DCR_GRP_DSKCHK_CNT = 60
[GRP_ASM]
DCR_EP_NAME = ASM0 #ASM节点名，和dmasvrmal的MAL_INST_NAME一致
DCR_EP_SHM_KEY = 93360 #共享内存标识
DCR_EP_SHM_SIZE = 10 #共享内存大小
DCR_EP_HOST = 192.168.1.1 #心跳地址
DCR_EP_PORT = 5436 #ASM端口
DCR_EP_ASM_LOAD_PATH = /dev/raw
[GRP_ASM]
DCR_EP_NAME = ASM1
DCR_EP_SHM_KEY = 93361
DCR_EP_SHM_SIZE = 10
DCR_EP_HOST =192.168.1.2
DCR_EP_PORT = 5437
DCR_EP_ASM_LOAD_PATH = /dev/raw

[GRP]
DCR_GRP_TYPE = DB
DCR_GRP_NAME = GRP_DSC
DCR_GRP_N_EP = 2
DCR_GRP_DSKCHK_CNT = 60
[GRP_DSC]
DCR_EP_NAME = DSC0 #实例名，和dm.ini的INSTANCE_NAME一致
DCR_EP_SEQNO = 0 #组内序号，不能重复
DCR_EP_PORT = 5236 #实例端口，和dm.ini的PORT_NUM一致
DCR_CHECK_PORT = 5536 #DCR检查端口
[GRP_DSC]
DCR_EP_NAME = DSC1
DCR_EP_SEQNO = 1
DCR_EP_PORT = 5236
DCR_CHECK_PORT = 5537

1.2 初始化磁盘组

A机器
[dmdba@~]# /opt/dsc/dmdbms/bin/dmasmcmd
ASM> create dcrdisk '/dev/raw/raw1' 'dcr'
ASM> create votedisk '/dev/raw/raw2''vote'
ASM> create asmdisk '/dev/raw/raw3' 'LOG0'
ASM> create asmdisk '/dev/raw/raw4''DATA0'
ASM> init dcrdisk '/dev/raw/raw1' from'/opt/dsc/config/dmdcr_cfg.ini' identified by 'admin1234'
ASM> init votedisk '/dev/raw/raw2' from '/opt/dsc/config/dmdcr_cfg.ini'

create dcrdisk'/dev/raw1' 'dcr'
create votedisk'/dev/raw2' 'vote'
create asmdisk'/dev/raw3' 'LOG0'
create asmdisk'/dev/raw4' 'DATA0'
init dcrdisk'/dev/raw1' from '/data/businessServer/dsc0/config/dmdcr_cfg.ini' identified by'admin1234'
init votedisk'/dev/raw2' from '/data/businessServer/dsc0/config/dmdcr_cfg.ini'

1.3 创建dmasvrmal.ini

A机器、B机器配置相同
[dmdba@~]# vi /opt/dsc/config/dmasvrmal.ini
[MAL_INST1]
MAL_INST_NAME = ASM0
MAL_HOST = 192.168.1.1 #心跳地址
MAL_PORT = 5636 #MAL监听端口
[MAL_INST2]
MAL_INST_NAME = ASM1
MAL_HOST = 192.168.1.2
MAL_PORT = 5637

1.4 创建dmdcr.ini

A机器
[dmdba@~]# vi /opt/dsc/config/dmdcr.ini
DMDCR_PATH = /dev/raw/raw1
DMDCR_MAL_PATH = /opt/dsc/config/dmasvrmal.ini
DMDCR_SEQNO = 0
DMDCR_AUTO_OPEN_CHECK = 90

#DMDCR_ASM_RESTART_INTERVAL = 30 #CSS认定ASM故障重启的时间
#DMDCR_ASM_STARTUP_CMD =/opt/dsc/dmdbms/bin/dmasmsvr dcr_ini=/opt/dsc/config/dmdcr.ini

#DMDCR_DB_RESTART_INTERVAL =60 #CSS认定DSC故障重启的时间
#DMDCR_DB_STARTUP_CMD =/opt/dsc/dmdbms/bin/dmserver path=/opt/dsc/config/dsc0_config/dm.inidcr_ini=/opt/dsc/config/dmdcr.ini
B机器
[dmdba@~]# vi /opt/dsc/config/dmdcr.ini
DMDCR_PATH = /dev/raw/raw1
DMDCR_MAL_PATH = /opt/dsc/config/dmasvrmal.ini
DMDCR_SEQNO = 1
DMDCR_AUTO_OPEN_CHECK = 90

#DMDCR_ASM_RESTART_INTERVAL = 30
#DMDCR_ASM_STARTUP_CMD =/opt/dsc/dmdbms/bin/dmasmsvr dcr_ini=/opt/dsc/config/dmdcr.ini

#DMDCR_DB_RESTART_INTERVAL =60
#DMDCR_DB_STARTUP_CMD =/opt/dsc/dmdbms/bin/dmserver path=/opt/dsc/config/dsc1_config/dm.inidcr_ini=/opt/dsc/config/dmdcr.ini
注意：当前为手动拉起A机器和B机器的ASM和DMSERVER服务。待集群配置完成后，再修改为自动拉起（删除dmdcr.ini中红色井号）。

1.5 启动CSS、ASM服务

A机器、B机器依次执行
[dmdba@~]# /opt/dsc/dmdbms/bin/dmcssDCR_INI=/opt/dsc/config/dmdcr.ini
...
DMCSS IS READY
A机器、B机器依次执行
[dmdba@~]# /opt/dsc/dmdbms/bin/dmasmsvrDCR_INI=/opt/dsc/config/dmdcr.ini
...
the ASM server is Ready.

1.6 创建DMASM磁盘组

A机器
[dmdba@~]# /opt/dsc/dmdbms/bin/dmasmtoolDCR_INI=/opt/dsc/config/dmdcr.ini

1.7 创建dminit.ini

mal_port = 5736
log_path = +DMLOG/log/dsc0_log01.log
log_path = +DMLOG/log/dsc0_log02.log
[DSC1]
config_path = /opt/dsc/config/dsc1_config
port_num = 5236
mal_host = 192.168.1.2
mal_port = 5737
log_path = +DMLOG/log/dsc1_log01.log
log_path = +DMLOG/log/dsc1_log02.log

ARCH_FILE_SIZE = 1024
ARCH_SPACE_LIMIT = 51200
[ARCHIVE_REMOTE]
ARCH_TYPE = REMOTE
ARCH_DEST = DSC1

ARCH_FILE_SIZE = 1024
ARCH_SPACE_LIMIT = 51200

1.10 启动DMSERVER服务

A机器
[dmdba@~]# /opt/dsc/dmdbms/bin/dmserver/opt/dsc/config/dsc0_config/dm.ini dcr_ini=/opt/dsc/config/dmdcr.ini
B机器
[dmdba@~]# /opt/dsc/dmdbms/bin/dmserver/opt/dsc/config/dsc1_config/dm.ini dcr_ini=/opt/dsc/config/dmdcr.ini

1.11 注册CSS、ASM、DMSERVER后台服务

A机器
[root@~]#/opt/dsc/dmdbms/script/root/dm_service_installer.sh -t dmcss -dcr_ini/opt/dsc/config/dmdcr.ini -p CSS
[root@~]#/opt/dsc/dmdbms/script/root/dm_service_installer.sh -t dmasmsvr -dcr_ini/opt/dsc/config/dmdcr.ini -y DmCSSServiceCSS.service -p ASM
[root@~]#/opt/dsc/dmdbms/script/root/dm_service_installer.sh -t dmserver -dm_ini/opt/dsc/config/dsc0_config/dm.ini -dcr_ini /opt/dsc/config/dmdcr.ini -yDmASMSvrServiceASM.service -p DSC
B机器
[root@~]#/opt/dsc/dmdbms/script/root/dm_service_installer.sh -t dmcss -dcr_ini/opt/dsc/config/dmdcr.ini -p CSS
[root@~]#/opt/dsc/dmdbms/script/root/dm_service_installer.sh -t dmasmsvr -dcr_ini/opt/dsc/config/dmdcr.ini -y DmCSSServiceCSS.service -p ASM
[root@~]#/opt/dsc/dmdbms/script/root/dm_service_installer.sh -t dmserver -dm_ini/opt/dsc/config/dsc1_config/dm.ini -dcr_ini /opt/dsc/config/dmdcr.ini -yDmASMSvrServiceASM.service -p DSC

备注：删除自启

[root@~]#/opt/dsc/dmdbms/script/root/dm_service_uninstaller.sh -n DmCSSServiceCSS
[root@~]#/opt/dsc/dmdbms/script/root/dm_service_uninstaller.sh -n DmASMSvrServiceASM
[root@~]#/opt/dsc/dmdbms/script/root/dm_service_uninstaller.sh -n DmServiceDSC

2.配置监视器

2.1 创建dmcssm.ini

A机器、B机器配置相同
[dmdba@~]# vi /opt/dsc/dmdbms/bin/dmcssm.ini
CSSM_OGUID = 45331
CSSM_CSS_IP = 192.168.1.1:5336
CSSM_CSS_IP = 192.168.1.2:5337
CSSM_LOG_PATH = ../log
CSSM_LOG_FILE_SIZE = 512
CSSM_LOG_SPACE_LIMIT = 2048

2.2注册服务（选做）

[root@~]# /opt/dsc/dmdbms/script/root/dm_service_installer.sh-t dmcssm -cssm_ini /opt/dsc/dmdbms/bin/dmcssm.ini -p Monitor
备注：删除自启
[root@~]# /opt/dsc/dmdbms/script/root/dm_service_uninstaller.sh-n DmCSSMonitorServiceMonitor

2.3 监视器使用

show 查看所有组的信息
show config 查看dmdcr_cfg.ini 的配置信息
show monitor 查看当前连接到主 CSS 的所有监视器信息

3.启停服务

3.1 启动监视器

[dmdba@~]# /opt/dsc/dmdbms/bin/DmCSSMonitorServiceMonitor start

前台启动：
[dmdba@~]# /opt/dsc/dmdbms/bin/dmcssm INI_PATH=/opt/dsc/dmdbms/bin/dmcssm.ini

3.2 启停集群

启动：A/B机器CSS
A/B机器：[dmdba@~]# /opt/dsc/dmdbms/bin/DmCSSServiceCSS start
说明：CSS启动后30秒自动拉起ASM，60秒自动拉起DMSERVER。

停止：A/B机器DMSERVER→A/B机器ASM→A/B机器CSS
A/B机器：[dmdba@~]# /opt/dsc/dmdbms/bin/DmServiceDSC stop
A/B机器：[dmdba@~]# /opt/dsc/dmdbms/bin/DmASMSvrServiceASM stop
A/B机器：[dmdba@~]# /opt/dsc/dmdbms/bin/DmCSSServiceCSS stop

**说明： **
1)DSC正常停库必须2节点同时停止，根据目前脚本配置，CSS启动后30秒自动拉起ASM，60秒自动拉起DMSERVER，所以停止DMSERVER和ASM后，要尽快停止CSS，避免被自动拉起。

2)ASM服务在任意节点停止，2个节点的ASM服务都会停止，为了保险起见，可以两边都执行停止命令。3)服务全部停止后，要检查后台进程是否全部停止。
