In a database management system, the archive log is a file that contains a history of all the changes made to the database. This information can be used to recover the database if it is damaged or lost. The archive log is also used to track the progress of database backups.
The size of the archive log can vary depending on the size of the database and the frequency of changes made to the database. It is important to monitor the size of the archive log and to make sure that it does not grow too large. If the archive log grows too large, it can impact the performance of the database.
