Clearing the transaction logs

A transactional log is simply a binary file where transactions are written. Transaction logging keeps a sequential record of every operation that occurs to your data. If a database becomes corrupted, we can "roll back" the database to a point before it was corrupted and replay the changes from the transaction log.

Do not to delete these files as this action might cause application server function failure.
