Checkpoint Interval

The checkpoint interval is important for DB2 recovery processing. The longer amount of time between checkpoint intervals, the more your DB2 applications are exposed to a longer restart time in case of a system failure. The checkpoint interval is set with the LOGLOAD parameter in the DSNZPARMs. In addition, it can be changed dynamically with the -SET LOG LOGLOAD command. This parameter is based on the number of log records written. You may also specify the interval in terms of minutes with the -SET LOG CHKTIME command.
