1.4 用户准备
使用 root 用户创建用于搭建环境的用户和组，以下192.168.17.11,192.168.17.12两机器都要做。
#新建组dmdba
groupadd dmdba
#在组dmdba（第一个）中创建一个用户dmdba（第二个）
useradd -g dmdba dmdba
#为用户dmdba设置密码
passwd dmdba
#用户输入密码
dmdba
1.5 目录与存储规划
1.5.1 本地磁盘规划
| 名称 | 拟定配置 | 备注 |
|---|---|---|
| 数据库安装目录 | /home/dmdba/dmdsc | 数据库安装路径，存放数据库运行日志等信息 |
| 数据库备份目录 | /home/dmdba/dmbak | 用于存放数据库备份文件 |
| 数据库SQL日志目录 | /home/dmdba/dmdsc/log | 用于存放数据库dmsql日志 |
| 集群配置文件目录 | /home/dmdba/dmdsc/data | 用于存放数据库集群配置文件 |
1.5.2 共享存储规划
| 名称 | 拟定配置 | 分区大小 | 备注 |
|---|---|---|---|
| DCR | /dev_DSC2/DCR:/dev/sdd1 | 5GB | 用于存储、维护集群配置的详细信息，整个集群环境共享 DCR 配置信息 |
| VOTE | /dev_DSC2/VOTE:/dev/sde1 | 5GB | 记录集群成员信息,集群通过 Voting Disk 进行心跳检测，确定集群中节点的状态 |
| LOG | /dev_DSC2/DMLOG:/dev/sdg1 | 30GB | 用于存储数据库集群Redo log |
| DATA | /dev_DSC2/DMDATA:/dev/sdc1 | 30GB | 用户存放数据 |
| ARCH | /dev_DSC2/DMARCH:/dev/sdf1 | 30GB | 用于存储数据库集群各实例的归档日志 |
DMDSC集群是为了实现多实例同时访问和修改数据，因此要求数据文件、控制文件和日志文件放到共享存储上。DM支持两种共享存储，裸设备和DMASM，裸设备是未经过格式化的特殊字符设备；DMASM是在裸设备基础上部署了文件系统，便于对裸设备上的磁盘和文件进行管理。
VOTE是表决磁盘，记录集群成员的信息，对节点的心跳信息进行检测，确定节点的状态；表决磁盘还用来传递命令，通知节点执行相应命令，只支持裸设备，一个集群一个表决磁盘。
DCR是DM 集群注册表的简称，用于存储、维护集群配置的详细信息，整个集群环境共享 DCR 配置信息，包括 DMDSC、DMASM、DMCSS资源，包括实例名、监听端口、集群中故障节点信息等，只支持裸设备，一个集群一个注册表。
1.5.3 共享存储挂载

1.5.3.2 udev绑定块设备
1.5.3.2.1 通过 scsi_id 获取磁盘信息
[root@dmdsc1 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdc1
14f504e46494c45525732313256352d516f53422d644c4a4b
[root@dmdsc1 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdd1
14f504e46494c45526d4e7150565a2d314147582d58655444
[root@dmdsc1 ~]# /usr/lib/udev/scsi_id -g -u /dev/sde1
14f504e46494c455253434d6a36372d6674634e2d566e384d
[root@dmdsc1 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdf1
14f504e46494c455269343938586c2d424d54332d754f3274
[root@dmdsc1 ~]# /usr/lib/udev/scsi_id -g -u /dev/sdg1
14f504e46494c4552366b444850622d596774752d5a597659
[root@dmdsc1 ~]#
本步骤的目的是为了在下一步中将相同 scsi_id 的磁盘创建相同的盘符。例如，下一步骤中 RESULT=="14f504e46494c45526d4e7150565a2d314147582d58655444"即为将 scsi_id 为14f504e46494c45526d4e7150565a2d314147582d58655444的磁盘命名为 DCR 磁盘，并将 DCR 磁盘软链接到/dev_DSC2 目录下并命名为 DCR。
1.5.3.2.2 创建磁盘链接
编写/etc/udev/rules.d/66-dmdevices.rules 配置信息，创建磁盘链接。书写时一个 KERNEL 为一行，不能换行。
[root@dmdsc1 ~]# cat /etc/udev/rules.d/66-dmdevices.rules
## DCR磁盘配置,且在软链接之前创建文件夹 /dev_DSC2
KERNEL=="sd*",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="14f504e46494c45526d4e7150565a2d314147582d58655444",SYMLINK+="DCR", OWNER="dmdba", GROUP="dmdba", MODE="0660", RUN+="/bin/sh -c 'chown dmdba:dmdba /dev/$name;mkdir -p /dev_DSC2; ln -s /dev/DCR /dev_DSC2/DCR'"
## VOTE 磁盘配置
KERNEL=="sd*",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="14f504e46494c455253434d6a36372d6674634e2d566e384d",SYMLINK+="VOTE", OWNER="dmdba", GROUP="dmdba", MODE="0660", RUN+="/bin/sh -c 'chown dmdba:dmdba /dev/$name; ln -s /dev/VOTE /dev_DSC2/VOTE'"
## DMDATA 磁盘配置
KERNEL=="sd*",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="14f504e46494c45525732313256352d516f53422d644c4a4b",SYMLINK+="DMDATA", OWNER="dmdba", GROUP="dmdba", MODE="0660", RUN+="/bin/sh -c 'chown dmdba:dmdba /dev/$name; ln -s /dev/DMDATA /dev_DSC2/DMDATA'"
## DMARCH 磁盘配置
KERNEL=="sd*",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="14f504e46494c455269343938586c2d424d54332d754f3274",SYMLINK+="DMARCH", OWNER="dmdba", GROUP="dmdba", MODE="0660", RUN+="/bin/sh -c 'chown dmdba:dmdba /dev/$name; ln -s /dev/DMARCH /dev_DSC2/DMARCH ; chown -R dmdba:dmdba /dev_DSC2'"
## DMLOG 磁盘配置，且在搭建完成之后，将权限直接赋予 dmdba组的dmdba用户
KERNEL=="sd*",SUBSYSTEM=="block",PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",RESULT=="14f504e46494c4552366b444850622d596774752d5a597659",SYMLINK+="DMLOG", OWNER="dmdba", GROUP="dmdba", MODE="0660", RUN+="/bin/sh -c 'chown dmdba:dmdba /dev/$name; ln -s /dev/DMLOG /dev_DSC2/DMLOG ; chown -R dmdba:dmdba /dev_DSC2'"
[root@dmdsc1 ~]#
从配置信息可以看出，通过 scsi id 找到磁盘后，在 /dev/下命名了磁盘信息，然后再做软链接到 /dev_DSC2 下。软链接的目录可以是/dev 下的独立目录，也可以是其他自行创建的独立目录，例如本例中的/dev_DSC2，目录路径必须以“/dev”开始，否则 DM 不会认为这是使用物理磁盘的真实环境。
之所以要软链接到独立目录，是因为 DMDSC 启动时会扫描目录下所有磁盘，如果目录中存在与当前 DMDSC 系统 GROUP_ID/DISK_ID 有冲突的磁盘（例如存在两块 GROUP_ID=0 且 DISK_ID=0 的磁盘），则 DMDSC 将启动失败。因此需要软链接到独立目录，保证该目录下仅包含当前 DMDSC 系统使用的共享存储磁盘，避免 DMDSC 启动失败。
以上配置在192.168.17.11和192.168.17.12机器完全相同，2 台机器均完成之后，进行下一步。
1.5.3.2.3 重启 systemd-udev-trigger 服务
#2个数据库节点都需要重启服务
[root@dmdsc1 ~]# systemctl restart systemd-udev-trigger
[root@dmdsc2 ~]# systemctl restart systemd-udev-trigger
重启服务后，搭建之前磁盘权限信息如下：
[root@dmdsc1 ~]# ls -lth /dev_DSC2/

二、DMDSC部署过程
2.1 安装DMDSC软件
可参考《DM8安装手册》。和单机安装相同
2个节点数据库机器都要做。
使用 dmdba 用户创建用于 DSC 环境搭建的目录：/home/dmdba/dmdsc。
DM 执行码和工具存放于目录：/home/dmdba/dmdsc/bin。
安装过程如下：
[root@dmdsc1 ~]# mount -o loop dm8_20250811_x86_centos7_64.iso /mnt
mount: /dev/loop0 is write-protected, mounting read-only
[root@dmdsc1 ~]# su - dmdba
[dmdba@dmdsc1 ~]$ /mnt/DMInstall.bin -i

2.12 配置 DMCSSM 监视器
现在我们搭建监视器，配置 DMCSSM.INI 文件。
DMCSSM 在任何机器上均可以启动，只要该台机器和 DMDSC 的真实机器网络是相通的，就可以监控 DMDSC 集群信息。
这里我们选择在192.168.17.11机器上搭建监视器。/home/dmdba/dmdsc/data 目录中 DMCSSM.INI 详细内容如下：
[dmdba@dmdsc1 ~]$ vi /home/dmdba/dmdsc/data/dmcssm.ini
[dmdba@dmdsc1 ~]$ cat /home/dmdba/dmdsc/data/dmcssm.ini
#和DMDCR_CFG.INI中的DCR_OGUID保持一致
CSSM_OGUID = 1071107589
#配置所有CSS的连接信息，
#与DMDCR_CFG.INI中CSS配置项的DCR_EP_HOST和DCR_EP_PORT保持一致
CSSM_CSS_IP = 10.18.18.11:9836
CSSM_CSS_IP = 10.18.18.12:9837
CSSM_LOG_PATH = /home/dmdba/dmdsc/data/cssm_log #监视器日志文件存放路径
CSSM_LOG_FILE_SIZE = 32 #每个日志文件最大32M
CSSM_LOG_SPACE_LIMIT = 0 #不限定日志文件总占用空间
[dmdba@dmdsc1 ~]$
创建 DMCSSM 的日志存放路径。
[dmdba@dmdsc1 ~]$ mkdir /home/dmdba/dmdsc/data/cssm_log [dmdba@dmdsc1 ~]$
注册 DMCSSM 服务，在root下执行
[root@dmdsc1 ~]# /home/dmdba/dmdsc/script/root/dm_service_installer.sh -t dmcssm -cssm_ini /home/dmdba/dmdsc/data/dmcssm.ini -p Monitor
Created symlink from /etc/systemd/system/multi-user.target.wants/DmCSSMonitorServiceMonitor.service to /usr/lib/systemd/system/DmCSSMonitorServiceMonitor.service.
创建服务(DmCSSMonitorServiceMonitor)完成
[root@dmdsc1 ~]#
三、启停服务
3.1 启动集群
启动顺序：1节点/2节点机器CSS→1节点/2节点机器ASM→1节点/2节点机器DMSERVER
[dmdba@dmdsc1 ~]$ /home/dmdba/dmdsc/bin/DmCSSServiceCSS start Starting DmCSSServiceCSS: [ OK ] [dmdba@dmdsc2 ~]$ /home/dmdba/dmdsc/bin/DmCSSServiceCSS start Starting DmCSSServiceCSS: [ OK ] [dmdba@dmdsc1 ~]$ /home/dmdba/dmdsc/bin/DmASMSvrServiceASM start Starting DmASMSvrServiceASM: [ OK ] [dmdba@dmdsc2 ~]$ /home/dmdba/dmdsc/bin/DmASMSvrServiceASM start Starting DmASMSvrServiceASM: [ OK ] [dmdba@dmdsc1 ~]$ /home/dmdba/dmdsc/bin/DmServiceDSC start Starting DmServiceDSC: connnect dmasmtool(dmasmtoolm) successfully.

3.2 启动 DMCSSM 集群监视器
在192.168.17.11机器上前台启动DMCSSM集群监视器，并用show命令查看集群状态
[dmdba@dmdsc1 ~]$ cd /home/dmdba/dmdsc/bin
[dmdba@dmdsc1 bin]$ ./dmcssm ini_path=/home/dmdba/dmdsc/data/dmcssm.ini
[monitor] [2025-09-09 18:48:48:636] CSS MONITOR V8

3.3 停止集群
停止顺序：1节点/2节点机器DMSERVER→1节点/2节点机器ASM→1节点/2节点机器CSS
[dmdba@dmdsc1 ~]$ /home/dmdba/dmdsc/bin/DmServiceDSC stop Starting DmServiceDSC: connnect dmasmtool(dmasmtoolm) successfully. [ OK ] [dmdba@dmdsc1 ~]$ [dmdba@dmdsc2 ~]$ /home/dmdba/dmdsc/bin/DmServiceDSC stop Starting DmServiceDSC: connnect dmasmtool(dmasmtoolm) successfully. [ OK ] [dmdba@dmdsc2 ~]$ [dmdba@dmdsc1 ~]$ /home/dmdba/dmdsc/bin/DmASMSvrServiceASM stop Starting DmASMSvrServiceASM: [ OK ] [dmdba@dmdsc2 ~]$ /home/dmdba/dmdsc/bin/DmASMSvrServiceASM start Starting DmASMSvrServiceASM: [ OK ] [dmdba@dmdsc1 ~]$ /home/dmdba/dmdsc/bin/DmCSSServiceCSS stop Starting DmCSSServiceCSS: [ OK ] [dmdba@dmdsc2 ~]$ /home/dmdba/dmdsc/bin/DmCSSServiceCSS stop Starting DmCSSServiceCSS: [ OK ]
3.4 DMDSC 归档配置方法
一般建议 DMDSC 集群中的节点，除了配置本地归档之外，再双向配置集群中所有其他节点的远程归档。查询 vdm_arch_ini、varch_status 等动态视图可以获取归档配置以及归档状态等相关信息。
3.4.1 配置 DMARCH.INI 文件
在192.168.17.11机器上修改dm.ini配置文件，准备 dmarch.ini 配置文件，保存到/home/dmdba/dmdsc/data/DSC01/DSC01_conf 目录下。
#dm.ini配置文件把ARCH_INI=0修改成ARCH_INI=1
[dmdba@dmdsc1 ~]$ vi /home/dmdba/dmdsc/data/DSC01/DSC01_conf/dm.ini
[dmdba@dmdsc1 ~]$ grep "ARCH_INI" /home/dmdba/dmdsc/data/DSC01/DSC01_conf/dm.ini
ARCH_INI = 1 #dmarch.ini
[dmdba@dmdsc1 ~]$
#新增dmarch.ini配置文件
[dmdba@dmdsc1 ~]$ vi /home/dmdba/dmdsc/data/DSC01/DSC01_conf/dmarch.ini
[dmdba@dmdsc1 ~]$ cat /home/dmdba/dmdsc/data/DSC01/DSC01_conf/dmarch.ini
[ARCHIVE_LOCAL1]
ARCH_TYPE = LOCAL
ARCH_DEST =+DMARCH/DSC01/arch
ARCH_FILE_SIZE = 2048
ARCH_SPACE_LIMIT = 0
[ARCH_REMOTE1]
ARCH_TYPE = REMOTE
ARCH_DEST = DSC02
ARCH_INCOMING_PATH =+DMARCH/DSC02/arch
[dmdba@dmdsc1 ~]$
在192.168.17.12机器上修改dm.ini配置文件，准备 dmarch.ini 配置文件，保存到/home/dmdba/dmdsc/data/DSC02/DSC02_conf 目录下。
#dm.ini配置文件把ARCH_INI=0修改成ARCH_INI=1
[dmdba@dmdsc2 bin]$ vi /home/dmdba/dmdsc/data/DSC02/DSC02_conf/dm.ini
[dmdba@dmdsc2 bin]$ grep "ARCH_INI" /home/dmdba/dmdsc/data/DSC02/DSC02_conf/dm.ini
ARCH_INI = 1 #dmarch.ini
[dmdba@dmdsc2 bin]$
#新增dmarch.ini配置文件
[dmdba@dmdsc2 bin]$ vi /home/dmdba/dmdsc/data/DSC02/DSC02_conf/dmarch.ini
[dmdba@dmdsc2 bin]$ cat /home/dmdba/dmdsc/data/DSC02/DSC02_conf/dmarch.ini
[ARCHIVE_LOCAL1]
ARCH_TYPE = LOCAL
ARCH_DEST = +DMARCH/DSC02/arch
ARCH_FILE_SIZE = 2048
ARCH_SPACE_LIMIT = 0
[ARCH_REMOTE1]
ARCH_TYPE = REMOTE
ARCH_DEST = DSC01
ARCH_INCOMING_PATH = +DMARCH/DSC01/arch
[dmdba@dmdsc2 bin]$
3.4.2 重启集群实例
2个节点同时重启DSC实例
[dmdba@dmdsc1 ~]$ /home/dmdba/dmdsc/bin/DmServiceDSC restart Stopping DmServiceDSC: [ OK ] Starting DmServiceDSC: connnect dmasmtool(dmasmtoolm) successfully. [ OK ] [dmdba@dmdsc1 ~]$ [dmdba@dmdsc2 bin]$ /home/dmdba/dmdsc/bin/DmServiceDSC restart Stopping DmServiceDSC: [ OK ] Starting DmServiceDSC: connnect dmasmtool(dmasmtoolm) successfully. [ OK ] [dmdba@dmdsc2 bin]$
3.4.3 验证归档和集群
通过创建sy_test测试表并插入数据，验证2个节点数据是否同步。
#连接节点1，创建sy_test表验证集群是否一致性
