Table Corruption in MySQL Database

A Request Tracker (RT) enables you to keep a record of all the operations performed in MySQL database. RT creates a session by using a MySQL database, a PERL (Practical Extraction and Report Language) based main engine and front-end web and mail interfaces. However, if RT is unable to store your transactions made into the MySQL component, chances are that your MySQL component is either corrupt or missing. Corruption of MySQL database component can occur due to MySQL database server malfunctioning, operating system failure, malicious software like virus and more. In such situations, you need to recover the MySQL database component by restoring it from the latest backup. But, if you have not maintained any backup or backup falls short of providing the required data, then you should repair your corrupted MySQL component to extract data from it. To do so, you need to use advanced MySQL Database Repair application.

Consider a practical scenario where you encounter the below error message when you attempt to save some changes in session_data table:

“RT couldn’t store your session. This may mean that that the directory ‘/extra/requesttracker/current/var/session_data’ isn’t writable or a database table is missing or corrupt.”

Cause:

The root cause behind occurrence of above error message is that the session_data table is either missing or corrupt.
