搭建思路:
1.虚拟机:三台,分别安装数据库,添加网络适配器;
2.集群环境:一主两备;三台分别初始化实例,正常启动关闭数据库,主库做备份,还原恢复给两个备库;
3.三台分别配置数据库文件,分别以mount方式启动数据库,修改oguid,数据库模式;
4.配置监视器,分别依次启动数据库–守护–监视器,刷新监视器查看数据库状态,没有问题,搭建完成。
演示操作:
1.数据库环境介绍:
数据库版本:V8
操作系统版本:ContOS 7
三台主机IP:192.168.10.6 ,192.168.10.7 ,192.168.10.8
三台主机实例名:GRP1_RWW_01 ,GRP1_RWW_02 ,GRP1_RWW_03
端口号:5236
2.安装数据库过程参考:
https://blog.csdn.net/weixin_48588449/article/details/107786517
3.三台分别初始化数据库实例:

create dm database success. 2020-08-26 22:46:15
[dmdba@localhost bin]$
4.分别启动数据库:
[dmdba@localhost bin]$ ./dmserver /dm8/data/DAMENG/dm.ini
。。。。。。。。。。。。。。。。。。。。。
pseg_crash_trx_rollback end
SYSTEM IS READY =======结尾出现这个,表示启动成功
===============================================================
exit
Server is stopping...
listener closed and all sessions disconnected
。。。。。。。。。。。。。
close lsnr socket
DM Database Server shutdown successfully. ====表示关闭数据库
[dmdba@localhost bin]$
我的环境中主机名,数据库安装目录,实例安装目录都相同;
5.备份
[dmdba@localhost bin]$ ./dmrman
dmrman V8
RMAN> backup database '/dm8/data/DAMENG/dm.ini' full to backup_file1 backupset '/dm8/data/BACKUP_FILE_01'

6.还原恢复
将主库GRP1_RWW_01备份集分别传给两个备库,还原恢复备份集;

-server 服务器信息(IP:PORT)
-auto 设置服务是否自动启动,值为true或false,默认true.
-m 设置服务器启动模式open或mount,只针对dmserver服务类型生效,可选
-y 设置依赖服务,此选项只针对systemd服务环境下的dmserver和dmasmsvr服务生效
-s 服务脚本路径,设置则忽略除-y外的其他参数选项
-h 帮助
