This feature will be removed in a future version of Microsoft SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
The Checkpoint method forces a write of dirty database pages.
For an instance of Microsoft SQL Server, database checkpoints are performed automatically and at user direction. Checkpoints verify the consistency of data and a database can be configured for log truncation on a checkpoint, as consistency is assumed when a checkpoint occurs. For more information about SQL Distributed Management Objects (SQL-DMO) and checkpoints, see TruncateLogOnCheckpoint Property and ConfigValue Object.
