Powerful Oracle database recovery software to recover your database efficiently

Sometimes, while working with Oracle database, the database tables get inaccessible and the possible reason may be the fact that the tables contains damaged blocks. This is the reason, for which the Oracle application can not be able to read the tables and the data becomes completely inaccessible thereof. However, in such cases, you can always opt for any Oracle database recovery software to recover all your seemingly lost data back.

In the above situations, you may come across some error messages like “ORA-01578 runtime error” , following which the table can not be accessed any further.

In Oracle, the block level corruption is the result of any improper or unsuccessful recovery attempt of the database table with the NOLOGGING action. Moreover, the reason of corruption can also be any virus/malware infection, corrupt file system, operating system crash or any other application malfunction.

In order to deal with the Oracle block corruption issues, you can use the following initialization parameters:

• DB_BLOCK_CHECKSUM- This option can help you calculate the checksum for every block before writing it onto the hard disk drive.

• DB_BLOCK_CHECKING- This is a process, which checks the data blocks for their internal consistency and the overall integrity.

Apart from the above, you can also take the help of the Oracle inbuilt utility RMAN, which can help you take backup of the database and recover it thereof. Moreover, this utility is capable of locating the block level corruption, if there is any, in course of taking backup or restoring the same.

However, with severe corruption, even sometimes, RMAN fails to fix the issue. Under any instance of such harsh corruption, if you do have any previously taken valid backup, you can restore the database from there. If you do not have any backup available or any unresolved error has ceased the restoration process, then, you need to repair Oracle database with the help of any dbf recovery software and recover the data.

These Oracle database recovery software are extremely powerful in scanning the media for the lost data and repair it to recover them back. Moreover, these utilities are 100% risk-free and recover dbf with the structure of the database being intact.

Stellar Phoenix Oracle Recovery is a reliable application to recover Oracle database irrespective of the dbf file corruption. The software works well on Oracle 9i, 10g, 11g and with highly interactive graphical user interface, quite easy to use by any one without even much knowledge over such recovery utilities.
