Tips to Resolve “Database Page Corruption” Error Message
InnoDB database engine saves all the data in the form of pages, linked in a B-tree structure. The B-tree or clustered database structure consists of various leaf nodes, each having its index node. The index node contains information related to primary key and all columns in the InnoDB table. Corruption or damage in the B-tree structure can occur due to various reasons, resulting into inaccessibility of all the table records.
Furthermore, it might also result in inaccessibility of complete database components records. In such situations, if you have a backup of the InnoDB database, then you can overcome the problem very easily. But if in case, you have not maintained any backup or the backup file is inaccessible, then the only way to isolate the problem is by repairing the corrupt InnoDB table by using an efficient third-party mysql database repair software.
As a practical instance, you receive the below error message, while attempting to access your InnoDB table:
“InnoDB: Database page corruption on disk or a failed
InnoDB: file read of page 97234.
InnoDB: You may have to recover from a backup.
090106 0:04:13 InnoDB: Page dump in ascii and hex (16384 bytes):

The same error message pops up when you try to access your InnoDB table. Furthermore, the database table records become inaccessible after the above error message appears.
Cause
The main cause for the occurrence of the above error message is corruption of metadata structure of the InnoDB table. Few main reasons for the corruption can be improper server shutdown, virus attack, and application malfunction.
