subject: Detect Data Block Corruption in Oracle Using RMAN [print this page] You can easily detect Oracle data block corruption using an inbuilt utility, called RMAN (Oracle Recovery Manager). This tool offers you a comprehensive way to effectively backup your database and recover it, in case of database corruption.

In case the RMAN cannot detect logical and physical corruption to Oracle database and fix it, the database remains inaccessible. You encounter the same behavior every time you try to open the database table. It causes severe data loss and puts you in need of DBF recovery solutions.
