DSC 共享存储集群搭建

一、共享磁盘创建与绑定

1.1 共享磁盘创建

1.1.1 共享磁盘一览表

磁盘名称	磁盘大小	虚拟设备节点编号	磁盘路径
DCR	2G	SCSI 0:1	E:\DSC_share\DSC_dcr.vmdk
VOTE	2G	SCSI 0:2	E:\DSC_share\DSC_vtd.vmdk
ARCH	4G	SCSI 0:3	E:\DSC_share\DSC_arch.vmdk
REDO	4G	SCSI 0:4	E:\DSC_share\DSC_rlog.vmdk
DATA	10G	SCSI 0:5	E:\DSC_share\DSC_data.vmdk

1.1.2 操作步骤

1.1.2.1 dsc_01虚拟机设置

首先在dsc_01上创建5块共享磁盘，步骤如下：

1、确保虚拟机关闭

2、右键左边栏上的虚拟机 —> 添加 —> 硬盘

3、选择下一步 —> SCSI

4、选择下一步 —> 创建新虚拟磁盘

5、选择下一步 —> 选择创建的磁盘大小、选择存储为单个文件

6、选择下一步 —> 选择创建的磁盘文件的存放位置以及具体名称

1.1.2.2 dsc_02虚拟机设置

dsc_02需要共享刚才在dsc_01上创建的5个磁盘，步骤如下：

1、确保虚拟机关闭

2、右键左边栏上的虚拟机 —> 添加 —> 硬盘

3、选择下一步 —> SCSI

4、选择下一步 —> 使用现有的虚拟磁盘

5、选择下一步 —> 选择在dsc_01创建的磁盘

到这一步，在硬件层面上两个虚拟机挂载了5块磁盘。

1.2 虚拟机配置文件修改

一个 vmdk 虚拟磁盘同一时间只允许一台虚拟机读写，缺少集群必须的几个参数，所以需要手动在.vmx文件中追加：

#关闭 VMware 宿主机侧的磁盘读写缓存、预读、异步写	
diskLib.dataCacheMaxSize=0		
diskLib.dataCacheMaxReadAheadSize=0
diskLib.dataCacheMinReadAheadSize=0
diskLib.dataCachePageSize=4096
diskLib.maxUnsyncedWrites = "0"
#关闭 VMware 的磁盘独占锁
disk.locking = "FALSE"
#开启 SCSI 总线共享模式
scsi0.sharedBus ="virtual"
#防止重启虚机后磁盘序号漂移
disk.EnableUUID = "TRUE"

找到虚拟机的配置文件，一般为.vmx结尾：

建议在Nodepad++中追加，这样编码格式不会乱：

注意⚠️：如果在记事本中打开编辑，不要保存，选择另存为，并将编码格式设置为ANSI，替换当前文件保存，不然会无法打开虚拟机。

1.3 软链接绑定磁盘

1.3.1 查看磁盘的UUID

[root@admin ~]# ls -lrth /dev/ASMDISK/
总用量 0
lrwxrwxrwx. 1 root root 6 9月  18 03:59 dmredo -> ../sdd
lrwxrwxrwx. 1 root root 6 9月  18 03:59 dmdata -> ../sdf
lrwxrwxrwx. 1 root root 6 9月  18 03:59 dmvote -> ../sdc
lrwxrwxrwx. 1 root root 6 9月  18 03:59 dmdcr -> ../sdb
lrwxrwxrwx. 1 root root 6 9月  18 03:59 dmarch -> ../sde

[root@admin ~]# for i in  b c d e f;
> do
> echo  /dev/sd$i
> /usr/lib/udev/scsi_id -g -u /dev/sd$i
> done
/dev/sdb
36000c29dc24a968bbea6797ef20c7acc
/dev/sdc
36000c2964e9df95623c6af99a046b507

/dev/sdf
36000c2915129c02054da5c89424f0ef2

1.3.2 软链接绑定磁盘

在主节点21（任意节点即可）配置udev规则：

vim /etc/udev/rules.d/99-dm-asm.rules

写入以下内容：

[root@admin rules.d]# cat 99-dm-asm.rules 
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",
RESULT=="36000c29dc24a968bbea6797ef20c7acc", SYMLINK+="ASMDISK/dmdcr",OWNER="dmdba", GROUP="dinstall",MODE="0660"
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",
RESULT=="36000c2964e9df95623c6af99a046b507", SYMLINK+="ASMDISK/dmvote",OWNER="dmdba", GROUP="dinstall",MODE="0660"
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",

KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",
RESULT=="36000c290a1474d074be12a97f854f57f", SYMLINK+="ASMDISK/dmarch",OWNER="dmdba", GROUP="dinstall",MODE="0660"
KERNEL=="sd*",ENV{DEVTYPE}=="disk",SUBSYSTEM=="block", PROGRAM=="/usr/lib/udev/scsi_id --whitelisted --replace-whitespace --device=/dev/$name",
RESULT=="36000c2915129c02054da5c89424f0ef2", SYMLINK+="ASMDISK/dmdata",OWNER="dmdba", GROUP="dinstall",MODE="0660"

1.3.3 加载udev规则

udevadm control --reload
udevadm trigger --type=devices --action=change

1.3.4 检验是否生效

[root@admin ~]# ls -lrth /dev/sd*
brw-rw----. 1 root  disk     8,  0 9月  18 03:46 /dev/sda
brw-rw----. 1 root  disk     8,  1 9月  18 03:46 /dev/sda1
brw-rw----. 1 root  disk     8,  2 9月  18 03:46 /dev/sda2
brw-rw----. 1 dmdba dinstall 8, 16 9月  18 03:59 /dev/sdb
brw-rw----. 1 dmdba dinstall 8, 80 9月  18 04:02 /dev/sdf
brw-rw----. 1 dmdba dinstall 8, 64 9月  18 04:02 /dev/sde
brw-rw----. 1 dmdba dinstall 8, 48 9月  18 09:19 /dev/sdd
brw-rw----. 1 dmdba dinstall 8, 32 9月  18 09:22 /dev/sdc

二、DSC集群端口规划

虚拟机名	IP地址	dcr磁盘路径	OGUID	CSS组名	CSS实例名	ASM组名	ASM实例名	DB组名	DB实例名
dsc_01	192.168.23.21	/dev/ASMDISK/dmdcr	63635	GRP_CSS	CSS0	GRP_ASM	ASM0	GRP_DSC	DSC0
dsc_02	192.168.23.22	/dev/ASMDISK/dmdcr	63635	GRP_CSS	CSS1	GRP_ASM	ASM1	GRP_DSC	DSC1

EP	DB_PORT	CSS_PORT	ASM_PORT	DCR_EP_SMH_KEY	DCR_CHECK_PORT	MAL_PORT	ASM_MAL_PORT
实例节点	数据库实例监听端口	CSS 集群控制进程端口	DMASM 实例监听端口	实例共享内存 KEY	DCR 磁盘心跳检查端口	DB MAL 通信端口	ASM MAL 通信端口
0	5236	9341	9351	93360	9741	9255	9355
1	5236	9342	9352	93361	9742	9266	9366

3.7 dmarch.ini（双节点）

节点21写入以下内容：

[dmdba@admin ~/dmdbms/bin]$ cd /home/dmdba/dm/dm_config
[dmdba@admin ~/dm_config]$cat dmarch0.ini 
[ARCHIVE_LOCAL1]
ARCH_TYPE                                = LOCAL

ARCH_LOCAL_SHARE                = 1

节点22写入以下内容：

[dmdba@admin ~/dmdbms/bin]$ cd /home/dmdba/dm/dm_config
[dmdba@admin ~/dm_config]$cat dmarch1.ini 
[ARCHIVE_LOCAL1]
ARCH_TYPE                                = LOCAL

注意⚠️：归档日志的大小不可以太大，因为自己创建的磁盘空间和实际的生产现场差距很大，所以需要尽量都按最小的容量去给，不然会一直报错，磁盘也被写满

3.8 sqllog.ini（双节点）

[dmdba@admin ~/dm_config]$cat sqllog.ini 
BUF_TOTAL_SIZE          = 102400 
BUF_SIZE                = 10240

SQL_TRACE_MASK  = 2:3:23:25
MIN_EXEC_TIME = 0 
USER_MODE   = 0

四、初始化ASM盘

[dmdba@admin ~/dmdbms/bin]$ ./dmasmcmd
ASM>create dcrdisk '/dev/ASMDISK/dmdcr' 'dmdcr'
ASM>create votedisk '/dev/ASMDISK/dmvote' 'dmvote'
ASM>create asmdisk '/dev/ASMDISK/dmarch' 'dmarch'
ASM>create asmdisk '/dev/ASMDISK/dmredo' 'dmredo'
ASM>create asmdisk '/dev/ASMDISK/dmdata' 'dmdata'
ASM>init dcrdisk '/dev/ASMDISK/dmdcr' from '/home/dmdba/dm/dm_config/dmdcr_cfg.ini' identified by 'Sysdba%_025'
ASM>init votedisk '/dev/ASMDISK/dmvote' from '/home/dmdba/dm/dm_config/dmdcr_cfg.ini'

五、准备启动脚本

5.1 准备CSS启动脚本

[dmdba@admin ~/dmdbms/bin]$cp ./service_template/DmCSSService ./
[dmdba@admin ~/dmdbms/bin]$vim DmCSSService

DCR_INI_PATH=%DCR_INI_PATH%
修改为
DCR_INI_PATH=/home/dmdba/dm/dm_config/dmdcr.ini

5.2 准备ASM启动脚本

[dmdba@admin ~/dmdbms/bin]$cp ./service_template/DmASMSvrService  ./
[dmdba@admin ~/dmdbms/bin]$vim DmASMSvrService

DCR_INI_PATH=%DCR_INI_PATH%
修改为
DCR_INI_PATH=/home/dmdba/dm/dm_config/dmdcr.ini

5.3 准备DMSERVER启动脚本

[dmdba@admin ~/dmdbms/bin]$ cp ./service_template/DmService  ./
[dmdba@admin ~/dmdbms/bin]$vim DmService

dsc_01：

INI_PATH=%INI_PATH%
修改为
INI_PATH=/home/dmdba/dm/dm_config/conf0/dm.ini

DCR_INI_PATH=%DCR_INI_PATH%
修改为
DCR_INI_PATH=/home/dmdba/dm/dm_config/dmdcr.ini

#文件中搜索MALLOC_ARENA_MAX
export MALLOC_ARENA_MAX=4
修改为
export MALLOC_ARENA_MAX=1

dsc_02：

INI_PATH=%INI_PATH%
修改为
INI_PATH=/home/dmdba/dm/dm_config/conf1/dm.ini

DCR_INI_PATH=%DCR_INI_PATH%
修改为
DCR_INI_PATH=/home/dmdba/dm/dm_config/dmdcr.ini

#文件中搜索MALLOC_ARENA_MAX
export MALLOC_ARENA_MAX=4
修改为
export MALLOC_ARENA_MAX=1

六、启动服务

6.1 前台启动 dmcssm 控制台

在任意节点启动均可：

[dmdba@admin ~]$ cd /home/dmdba/dm/dmdbms/bin

[dmdba@admin ~/dmdbms/bin]$./dmcssm ini_path=/home/dmdba/dm/dmdbms/bin/dmcssm.ini
[monitor]          [2026-09-18 03:47:28.434] CSS MONITOR V8
[monitor]          [2026-09-18 03:47:28.446] CSS MONITOR SYSTEM IS READY.

[monitor]          [2026-09-18 03:47:28.448] Wait CSS Control Node choosed...
[monitor]          [2026-09-18 03:47:34.482] Wait CSS Control Node choosed failed, if dmcss has startuped and ini configured correctly, please wait a little more before execute command.

6.2 启动两个节点的 CSS 服务

[dmdba@admin ~]$ cd /home/dmdba/dm/dmdbms/bin
[dmdba@admin ~/dmdbms/bin]$./DmCSSService start
Starting DmCSSService:                                     [ OK ]

6.3 关闭 DB 自动拉起

回到cssm控制前台，在控制台中输入：

set GRP_DSC auto restart off

七、创建ASM磁盘组

以192.168.23.21为主节点执行

[dmdba@admin ~]$ cd /home/dmdba/dm/dmdbms/bin
[dmdba@admin ~/dmdbms/bin]$./dmasmtool dcr_ini=/home/dmdba/dm/dm_config/dmdcr.ini
ASM>create diskgroup 'DMDATA' asmdisk '/dev/dm_shrdisk/dm_data'
ASM>create diskgroup 'DMLOG' asmdisk '/dev/dm_shrdisk/dm_rlog'
ASM>create diskgroup 'DMARCH' asmdisk '/dev/dm_shrdisk/dm_arch'

注意⚠️：确保ASM组成功拉起后，才可以创建磁盘组，不然tool工具无法使用

八、初始化数据库

8.1 初始化数据库

以192.168.23.21为主节点执行

[dmdba@admin ~]$ cd /home/dmdba/dm/dmdbms/bin
[dmdba@admin ~/dmdbms/bin]$./dminit control=/home/dmdba/dm/dm_config/dminit.ini

8.2 sqllog、mal文件替换到conf0/1目录

以192.168.23.21为主节点执行

[dmdba@admin ~/dmdbms/bin]$ cd /home/dmdba/dm/dm_config
[dmdba@admin ~/dm_config]$cp sqllog.ini ./conf0/
[dmdba@admin ~/dm_config]$mv sqllog.ini ./conf1/
[dmdba@admin ~/dm_config]$cp dmmal.ini ./conf0/
[dmdba@admin ~/dm_config]$mv dmmal.ini ./conf1/
[dmdba@admin ~/dm_config]$mv dmarch0.ini ./conf0/dmarch.ini
[dmdba@admin ~/dm_config]$mv dmarch1.ini ./conf1/dmarch.ini

8.3 修改dm.ini参数

以192.168.23.21为主节点执行

[dmdba@admin ~/dmdbms/bin]$ cd /home/dmdba/dm/dm_config
[dmdba@admin ~/dm_config]$vi ./conf0/dm.ini  #分别修改
[dmdba@admin ~/dm_config]$vi ./conf1/dm.ini  #分别修改

#将如下参数新增到文件结尾处或者找到对应参数修改对应的数值

DSC_N_CTLS=5000

8.4 发送conf1到1号节点

以192.168.23.21为主节点执行

[dmdba@admin ~/dmdbms/bin]$ cd /home/dmdba/dm/dm_config
[dmdba@admin ~/dm_config]$scp -rp conf1 dmdba@192.168.23.22:/home/dmdba/dm/dm_config

九、启动数据库

回到cssm控制台前台窗口，启动DSC集群组：

EP STARTUP GRP_DSC

使用show命令展示GRP_CSS、GRP_ASM、GRP_DSC三个组的全部状态信息：

可以看到三个组全部打开，处于工作状态，DSC搭建成功！
