Sets auto checkpoint on.

Syntax

ConfigPersistent ConfigPersistent.setAutocheckpoint(
  boolean auto_checkpoint
) throws ULjException

Parameters

Remarks

A database has checkpoint turned on when committed change operations are applied to the persistent rows in the persistent store. When auto checkpoint is active, a checkpoint occurs as part of each commit; otherwise, a transaction record is written to record the change and the persistent row storage is not changed until the application invokes the checkpoint method.

Change and commit operations operate faster when auto checkpoint is not active but database startup can be slower if many transactions without checkpoints exist.

Autocheckpoint is always true if indexes are not persistent or if row limitation is enabled.

Returns

This ConfigPersistent with the auto checkpoint set.
