All important database objects such as reports, tables, macros, forms, views, triggers, constraints, stored procedures etc are contained by the DBF file. These objects are very important for any database because if any of them get corrupted then entire database get corrupted or inaccessible and it can only recovered by applying any database repair tool.

To detect and fix any corrupted DBF file Oracle offers many methods, these methods are very helpful in the process of database repair and recovery. These methods include:

VALIDATE STRUCTURE– In this method every single data block are verified in the analyzed object and if any corruption are found in this process then rows are added to INVALID_ROWS table.

DBVerify– This is an external command-line utility. This command enables you to validate offline data files of the corrupted oracle database. Along with offline data files you can also apply this utility for checking validating of the backup database files.

DB_BLOCK_CHECKING– If the argument of this command is set as TRUE then Oracle takes out a walk-through of the data in database block for checking whether it’s self-consistent or not. This process may add extra overhead to server and so this setting is suggested only if you can accept the overhead.

DBMS_REPAIR– This commands enables you to find and fix any database corruption. In this process two administrations are required First Oracle database table that holds the total list of damaged blocks and second is index key which points to corrupted blocks.
