1.2.数据准备
配置集之前，必须先同步实例数据，确保两者保持完全一致，否则会出现文章最后部分的错误信息。
1.3.同步数据
1)A节点
#首先关闭数据库
systemctl stop DmServiceoa
#然后检查Dmap服务是否在运行,要确保在运行状态 systemctl status DmAPService
#切换到dmdba用户,执行进行脱机备份（数据库处于关闭状态下执行）。 su - dmdba
cd dmdbms/bin
./dmrman CTLSTMT="BACKUP DATABASE '/home/dmdba/dmdata/oa/dm.ini' FULL TO BACKUP_FILE1 BACKUPSET '/home/dmdba/dmdata/BACKUP_FILE_01'"
#拷贝脱机备份的文件到备库所在的机器
scp -r /home/dmdba/dmdata/BACKUP_FILE_01/ 192.168.0.155:/home/dmdba
scp -r /home/dmdba/dmdata/BACKUP_FILE_01/ 192.168.0.188:/home/dmdba
2)B节点
#首先关闭数据库
systemctl stop DmServiceoa
#然后检查Dmap服务是否在运行,要确保在运行状态
systemctl status DmAPService
#切换到dmdba用户,执行进行脱机备份（数据库处于关闭状态下执行）。
su - dmdba
cd dmdbms/bin
./dmrman CTLSTMT="RESTORE DATABASE '/home/dmdba/dmdata/oa/dm.ini' FROM BACKUPSET '/home/dmdba/BACKUP_FILE_01'"
./dmrman CTLSTMT="RECOVER DATABASE '/home/dmdba/dmdata/oa/dm.ini' UPDATE DB_MAGIC"
3)C节点
#首先关闭数据库
systemctl stop DmServiceoa
#然后检查Dmap服务是否在运行,要确保在运行状态
systemctl status DmAPService
#切换到dmdba用户,执行进行脱机备份（数据库处于关闭状态下执行）。
su - dmdba
cd dmdbms/bin
./dmrman CTLSTMT="RESTORE DATABASE '/home/dmdba/dmdata/oa/dm.ini' FROM BACKUPSET '/home/dmdba/BACKUP_FILE_01'"
./dmrman CTLSTMT="RECOVER DATABASE '/home/dmdba/dmdata/oa/dm.ini' UPDATE DB_MAGIC"
2.配置A节点
2.1.关服务
systemctl stop DmServiceoa
2.2.创建配置文件
mkdir -p /home/dmdba/dmdata/oa/arch
mkdir -p /home/dmdba/dmdata/malpath
chown -R dmdba.dinstall /home/dmdba/dmdata/malpath
chown -R dmdba.dinstall /home/dmdba/dmdata/oa/arch
touch /home/dmdba/dmdata/oa/{dmarch.ini,dmmal.ini,dmwatcher.ini}
chown dmdba.dinstall /home/dmdba/dmdata/oa/dmarch.ini
chown dmdba.dinstall /home/dmdba/dmdata/oa/dmmal.ini
chown dmdba.dinstall /home/dmdba/dmdata/oa/dmwatcher.ini
