The SYSCS_UTIL.SYSCS_CHECKPOINT_DATABASE system procedure checkpoints the database by flushing all cached data to disk.
No result is returned by this procedure.
If authentication and SQL authorization are both enabled, only the database owner has execute privileges on this procedure by default. See "Enabling user authentication" and "Setting the SQL standard authorization mode" in the Derby Developer's Guide for more information. The database owner can grant access to other users.
