配置

节点	Ip地址	角色	硬件配置
A	192.168.159.101	DSC0	1核 CPU /3.5GB 内存 / 40GB 磁盘
B	192.168.159.102	DSC1	1核 CPU /3.5GB 内存 / 40GB 磁盘
C	192.168.159.103	DW	1核 CPU /3.5GB 内存 / 40GB 磁盘

ASM软链接路径	指向的实际设备	用途说明	大小
/dev/dm/asm-dmdcr	/dev/sdb	DCR 盘（集群配置盘）	1G
/dev/dm/asm-dmvote	/dev/sdc	Vote 盘（仲裁盘）	1G
/dev/dm/asm-dmdata	/dev/sde	数据盘（存放数据文件）	10G
/dev/dm/asm-dmlog	/dev/sdd	日志盘（存放联机日志）	10G
/dev/dm/asm-dmarch	/dev/sdf	归档盘（存放归档日志）	10G

节点	实例端口	CSS监听端口	ASM监听端口	PORT_NUM	ASM MAL监听端口	DM MAL监听端口
A	5236	11286	11276	5236	11266	11246
B	5236	11286	11276	5236	11266	11246
C	5236	11286	11276	5236	11266	11246

两台虚拟机的OGUID为均210715。操作系统为CentOS Linux release 7.9 (Core)；达梦镜像版本为dm8_20251016_x86_CentOS7_64.iso；安装目录为/home/dmdba/dmdbms；实例目录为/home/dmdba/dmdbms/data。

搭建2节点DSC集群

精简流程如下（后续配置DW过程中会修改部分配置）

备份数据

关闭DSC集群的DB服务

/home/dmdba/dmdbms/bin/DmServiceDMS stop

初始化C机器中的实例

/home/dmdba/dmdbms/bin/dminit \
  PATH='/dmdata/data' \
  INSTANCE_NAME=DW01 \
  DB_NAME=DAMENG \
  SYSDBA_PWD=Dameng@123 \

  BLANK_PAD_MODE=1 \
  CASE_SENSITIVE=1 \
  CHARSET=0 \
  UNICODE_FLAG=1 \
  LOG_SIZE=512 \
  AUTO_OVERWRITE=1

进行脱机备份

/home/dmdba/dmdbms/bin/dmrman  DCR_INI=/home/dmdba/dmdbms/config/DSC0/dmdcr.ini
backup database '/home/dmdba/dmdbms/config/DSC0/dm.ini' full backupset '/home/dmdba/dmbak/BACKUP_FILE' compressed level 5 parallel 8;

检验备份有效性

check backupset '/home/dmdba/dmbak/BACKUP_FILE' ;

发送备份文件给C机器

scp -r /home/dmdba/dmbak/BACKUP_FILE dmdba@192.168.159.103:/home/dmdba/dmbak/

C机器中恢复

/home/dmdba/dmdbms/bin/dmrman 
check backupset '/home/dmdba/dmbak/BACKUP_FILE' ;
RESTORE DATABASE  '/dmdata/data/DAMENG/dm.ini' FROM BACKUPSET '/home/dmdba/dmbak/BACKUP_FILE';
RECOVER DATABASE '/dmdata/data/DAMENG/dm.ini' FROM BACKUPSET '/home/dmdba/dmbak/BACKUP_FILE';
RECOVER DATABASE '/dmdata/data/DAMENG/dm.ini' UPDATE DB_MAGIC;
