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.
Resolution:
To resolve the above error message and access the session_data table, you can follow these steps: Create a new directory and move the MySQL database to that directory. To do so, follow these steps:mkdir /extra/varmkdir /extra/var/libmv /var/lib/mysql /extra/var/lib/mysqlln -sn /extra/var/lib/mysql /var/lib/mysql
Next, you need to restart the MySQL database by using the below command:service mysqld restart
If you find the table corruption even after moving the database files, then you need to follow these steps to repair the table:Check the mysql database for the table named ?RT4? by using the below command:mysqlcheck -u root -h localhost RT4 -p
After checking, fix the mysql database table RT4 by using this command:mysqlcheck -r -u root -h localhost RT4 -p
Finally, recheck the mysql repaired table RT4 by using the following command:mysqlcheck -u root -h localhost RT4 -p
However, if you encounter the same error message even after following the above steps, then you should use advanced MySQLDatabase Repair software. Such MySQL Repair tools use advanced scanning methods to repair and restore MySQL database objects. With easy-to-use interface and illustrated plus user-friendly documentation, these repair tools are easily to implement.
