单机版在测试备份还原时报错，

1、还原全量备份版本没有问题， 但是执行 增量还原时 报错

RMAN> RESTORE DATABASE '/home/dmdba/dm_data/software/dmdbms/database/bbx/dm.ini' FROM BACKUPSET '/home/dmdba/dm_data/software/dmdbms/database/bbx/bak/db_bak_20251106002';

5、 检查 备份文件 没有问题

RMAN> CHECK BACKUPSET '/home/dmdba/dm_data/software/dmdbms/database/bbx/bak/arch_bak_20251106001';
