IBM AIX system, the important data of the traffic management system in the storage, is organized by the Oracle database.There are more than 200 Oracle data files in the file system that need to restore the data, without other files.
Solution:
After a complete backup of the fault disk, the internal structure of the Oracle data file is comprehensively analyzed and organized.Oracle data files are extremely chaotic because of the secondary damage.After finding some corresponding algorithms, according to this algorithm, the mapping table of most LP-PP was organized. The remaining part of it was manually verified, and finally the file system was fully spelling.Search for all index blocks in the file system and restore part of the data file according to the index block.The data files of the remaining loses are analyzed and reorganized according to the internal structure of the Oracle data file.
