Case:
Due to the long working life and aging hard disk, two of the three disks are physical damage, the RAID5 array is dropped, and the customer can try to solve the problem by themselves, and to restore the ticket system Oracle database.Customers contact the local data recovery company, and the local data recovery company’s capabilities and communication found that the technical strength is not trusted.The customer finally drove to the data recovery company Bailihui Computer City Room 1309.Recovery type: server data recovery, RAID5 data recovery, Oracle database recovery
Solution:
After testing, the No. 1 disk of the disk 1, 2, and 3 is a physical bad tract, and the magnetic head 2 is damaged. Only the No. 3 disk is good. Since the RAID5 array allows it to continue working without damaging a plate, it is allowed to continue working.At present, the two disks of No. 1 and No. 2 disk are not determined; we first adopt the virtual reorganization RAID5 array of No. 1 and No. 3 to extract data files for testing.The decompression is normal, but the recent Oracle database backup DMP file test cannot be restored normally. This can determine that the No. 1 disk is a hard disk first. His data is not synchronized with the two other data data.Open the data on the 2nd disk to restore the data; next, we will open the data on the 2nd disk on the Dustless Studio, successfully export the mirror file of the No. 2 set, and then use the Virtual RAID5 array of Virtual reorganization of the No. 2 and No. 3 to extractThe recent Oracle database backup DMP file is tested, which can be restored normally.
