Primarily because of its efficiency and scalability, many of the world’s largest companies use Oracle databases to store and manage some of the most valuable data. Oracle runs on a range of operating systems including, Oracle Linux, Red Hat Enterprise Linux, Windows, Solaris, HP-UX, OS X, z/OS, AIX, Asianux and SUSE Linux Enterprise Server. Although the database has built-in corruption protection and backup features to prevent data loss, even with highly redundant RAID systems, media failures, user error and other factors can lead to .DBF files corruption.

  • Common Causes of Oracle Databases Data Loss include:

    • RAID / SAN /server hardware failure
    • Accidental or intentional data deletion
    • Deleted or corrupted logs and backups
    • Improper formatting
    • Oracle ASM corruption
    • File system corruption
    • Oracle corrupted row data
    • Database logical damage

  • Depending on the database version, you might see messages indicating failure to access a .DBF file due to sudden hardware damage, mishandled RAID rebuilds, hard drive failures and other events.

    Other Common Oracle Database Errors:

    • ORA-01403 – data not found
    • ORA-00225 / 00227 - control file corruption
    • ORA-00353 - log corruption, indication of the location of the corruption
    • ORA-00354 - corrupt block header
    • ORA-00355 - change numbers are out of order

If you cannot access an Oracle database, immediately stop recording new data to your storage media. Completely shut down your system to prevent data overwrites and further data corruption and contact a professional data recovery company to avoid downtime and potential permanent data loss.
