Oracle Data Block Corrupted Post System Malfunctioning

Each Database Administrator (DBA) has his own story of Oracle database corruption

. While Oracle database corruption is rare, but when ever they happen, the DBAs surely have sleepless nights. It becomes easy for the DBAs to overcome database corruption, if they have created a valid backup of their database. But, in case the DBAs have forgotten to create a backup or backup file itself is corrupted, then these DBA's need to search for an effective third-party Oracle Database Recovery application that can repair their database.

While the reasons for Oracle database corruption are many, one of the most common is corruption of Oracle data block. These blocks are one of the main Oracle database elements that consists of various operating system blocks. The size of Oracle data block is assigned by a DBA at the time of creation of database. Each data block consists of a block directory, block header, free space, and ITL (transaction list).

Each Oracle data block needs to surpass the below communication points for physical storage:

Disk controller cache

Storage Area Network cache

Oracle SGA and sessions' PGA

UNIX buffer cache

Physical disk spindle

This block can be corrupted while transportation due to below reasons:

Damaged Input/Output hardware

Incompatible device driver

Memory issues

Paging problems

After the Oracle data block is corrupted, the data block becomes unreadable, further resulting into inaccessibility of Oracle database records. In such cases, it is advisable to restore the data from an updated database backup. But, if the data backup is deleted, corrupted, or damaged, then it becomes imperative for the DBA to repair database using an advanced oracle database recovery software.

An oracle database repair tool employs high-end scanning procedures to Recover Oracle Database and restore the recovered database at user-specified location. The database recovery utility is designed with an easy to understand user-interface, that helps the user perform recovery easily. Such tools are non-destructive and do not make any change to the original database file.

Oracle Recovery is capable of recovering almost all database components, such as, tables, synonyms, roles, cluster tables, schemas, views, table spaces, indexes, and sequences. Supported by Oracle 9i, the recovery tool can Recover Oracle Database after almost all instances of database corruption. It supports Windows XP and 2003 operating systems.
