The software restored data from incomplete backups of a large state-owned enterprise in southwest China. The ASM of a large enterprise database in Southwest China was accidentally damaged due to disk addition, the user re-creates the asm diskgroup and restores the hot backup. The database cannot be opened because the archive is lost.

Shi tan software engineer biot. wang opened the inconsistent Database Backup through the special recovery scheme. The approximate process is: manually modifying the bootstrap object and commit transaction; modifying the datafile header bypasses the existing archivelog, then open the database exp to export data and recreate the database. However, due to the loss of some redo, A ORA-600 error occurs during some table exp, which is specially restored through the DataBridge feature of the PRM-DUL tool.
