Does Reality support database check pointing
If a check-point is needed (e.g. for Reality host utilities like Veritas tape agents, Sun ZFS file systems, Windows Ghost...), either a simple TL-SWITCH can be used to give a known recovery point or the more advanced database freeze/unfreeze that is used by Physical Save.
Database freeze/unfreeze is available using Reality realdump commands - e.g. realdump -f -s database_name. This momentarily freeze all database operations and syncs data to disk, you can then call any transient utility routine (that requires use of the check-point) and then unfreezing the database with a realdump -u.
Refer to a realdump -? from a Reality host command prompt for descriptions of options and in the on-line docs.
Note: The sync option "-s" is only available from V14.0.
