–使用dsc集群备份对新实例进行还原

./dmrman CTLSTMT="RECOVER DATABASE '/home/dmdba/dmdata5237/DAMENG/dm.ini' FROM BACKUPSET '/home/dmdba/dmdata5236/DAMENG/bak/DB_DAMENG_FULL_2026_05_28_16_25_47'"

–将dsc 两个节点归档整合到还原的服务器，恢复到指定时间点

./dmrman CTLSTMT="RECOVER DATABASE '/home/dmdba/dmdata5237/DAMENG/dm.ini' WITH ARCHIVEDIR '/home/dmdba/dmdata/dmarch0','/home/dmdba/dmdata/dmarch1' UNTIL TIME '2026-05-28 16:34:59'"

–更新数据库魔数

./dmrman CTLSTMT="RECOVER DATABASE '/home/dmdba/dmdata5237/DAMENG/dm.ini' UPDATE DB_MAGIC";

– 启动数据库验证数据，符合预期，已还原到2026-05-28 16:34:59 时间点的数据

./dmserver /home/dmdba/dmdata5237/DAMENG/dm.ini
