The server rolls forward logical-log records

After locating the checkpoint record in the logical log, the database server rolls forward the logical-log records that were written after the most recent checkpoint record. This action reproduces all changes to the databases since the time of the last checkpoint, up to the point at which the uncontrolled shutdown occurred. The following figure illustrates this step.
