SyntaxMembers| Member name | Value | Description | |
|---|---|---|---|
| Passive | 0 | Checkpoint as many frames as possible without waiting for any database readers or writers to finish. Sync the db file if all frames in the log are checkpointed. | |
| Full | 1 | This mode blocks until there is no database writer and all readers are reading from the most recent database snapshot. It then checkpoints all frames in the log file and syncs the database file. This call blocks database writers while it is running, but not database readers. | |
| Restart | 2 | This mode works the same way as Full, except after checkpointing the log file it blocks until all readers are reading from the database file only. This ensures that the next client to write to the database file restarts the log file from the beginning. This call blocks database writers while it is running, but not database readers. |
