A checkpoint is a snapshot of an entire database. Up to 99 checkpoints can be maintained at any time.

Checkpointing can be performed at the database level only.

Each time you take a checkpoint, a set of files in the ckp and dmp directories is created. In addition, if journaling is enabled, a set of journal files, created in the jnl directory, is associated with the checkpoint at the start of the journal interval.

To use the checkpoint operation, you must be a privileged user (operator privilege or system administrator).

To ensure that a valid database checkpoint is always available, we recommend that you use the infodb command to verify the status of the database and checkpoints.
