  1.实验环境： 操作系统：银河麒麟V10 primary 192.168.17.7
standby 192.168.17.8
monitor 192.168.17.9   2.配置主机名： hostnamectl set-hostname primary hostnamectl set-hostname standby hostnamectl set-hostname monitor   3.检查防火墙 systemctl status firewalld 检查Selinux getenforce   4.安装DM8数据库   5.集群端口规划

数据库名  实例名 PORT_NUM MAL_HOST MAL_PORT MAL_DW_PORT MAL_INST_DW_PORT
DM01 DMSVR01 5236 192.168.17.7 55101 65101 45101

6.初始化实例

 7.DMRMAN备份主库

./DmServiceDMSVR01 stop

mkdir /dm8/backup

备份主库

RMAN> backup database '/dm8/data/DM01/dm.ini' full to full_02 backupset '/dm8/backup/full_02'

主库备份文件传到备库/dm8/backup

scp -r /dm8/backup/full_02/ [email protected]:/dm8/backup/

备库恢复

RMAN> restore database '/dm8/data/DM01/dm.ini' from backupset '/dm8/backup/full_02'

 11.注册服务

主库：[root@primary root]# ./dm_service_installer.sh -t dmwatcher -p DMWATCHER -watcher_ini /dm8/data/DM01/dmwatcher.ini

备库：[root@standby root]#  ./dm_service_installer.sh -t dmwatcher -p DMWATCHER -watcher_ini /dm8/data/DM01/dmwatcher.ini

监视器：[root@monitor root]# ./dm_service_installer.sh -t dmmonitor -p DMmonitor -monitor_ini /dm8/dmmonitor.ini

 

12.实时主备集群重启顺序要求：
1、关闭监视器
2、关闭主库守护进程
3、关闭备库守护进程
4、关闭主库实例
5、关闭备库实例
6、启动主库实例 (mount)
7、启动备库实例 (mount)
8、启动主库守护进程 (open)
9、启动备库守护进程 (open)
10、启动监视器
