6.1.10 DB buffering function
(1) DB buffering function
The DB buffering function temporarily stores SQL texts or stored procedure call
information into a CompactFlash card when they cannot be sent due to network
disconnection or failure of the database server computer.
After recovery, the buffered SQL texts or stored procedure call information are
automatically sent to the database. (Manual operation is also possible.)
