测试环境是单机，生产环境是dsc，需要将测试环境数据恢复到生产环境

首先备份测试环境单机数据库，可以使用dmrman（需要关闭数据库，因该环境还有其他同事测试，使用在线备份）

1、单机数据库备份

SQL> backup database full backupset '/dm8/backup/full_20240612' compressed level 1 parallel 4;

备份完成后生成备份/dm8/backup/full_202406

SQL> host ls /dm8/backup/full_20240612
full_20240612.bak  full_20240612.meta  full_20240612_0  full_20240612_1  full_20240612_2  full_20240612_3

2、将备份传输到dsc环境一个节点，我这里选择1节点，并且创建目录也是一样的

scp 略

3、停止dsc的server

使用dmcssm来停止

ep stop grp_dsc （group name 根据你自己的情况)

4、在1节点使用dmrman恢复

[dmdba@dsc1 backup]$ dmrman dcr_ini=/home/dmdba/dmdcr.ini

dmrman V8
