A log file may fill quickly (thus halting the server) if there is a large volume of activity on an SQL Server database. You can set the log file to Truncate on Checkpoint to significantly extend the life of the log file for a database.
To enable Truncate on Checkpoint in Microsoft SQL Server 6.5
Start Microsoft SQL Server Enterprise Manager, open the tree for the Server, and then open the Database Devices tree.
Double-click the name of the database on which this feature will be enabled.
From the Database tab, select Truncate.
From the Options tab, select Truncate Log on Checkpoint, and then click OK.
To enable Truncate on Checkpoint in Microsoft SQL Server 7.0
Start Microsoft SQL Server Enterprise Manager, open the tree for the Server, and then open the Databases tree.
Right-click the name of the database on which this feature will be enabled and choose Properties.
From the Options tab, select Truncate log on checkpoint, and then click OK.
