Checkpoints in real-time tasks save the task status to persistent storage, enabling restoration to the pre-crash state after an unexpected failure.
Procedure
-
For more information, see the real-time mode configuration entry to access the Real-time Mode configuration page.
-
On the configuration panel, in the Checkpoint Configuration section, configure the checkpoint parameters.
ImportantIf you configure the checkpoint both here and in Runtime Parameter, the following logic applies:
-
If the checkpoint is not set here, the Runtime Parameter configuration is applied.
-
If the checkpoint is set here, this configuration overrides the Runtime Parameter setting.
Parameter
Description
System Checkpoint Interval
The time interval for executing checkpoints. Default: 180 seconds. You can specify the value in days, hours, minutes, or seconds. If left blank, checkpoints are disabled.
Minimum Time Interval Between Two System Checkpoints
The minimum time between two consecutive system checkpoints. Default: 180 seconds. You can specify the value in days, hours, minutes, or seconds.
ImportantSet this parameter when the maximum degree of parallelism for checkpoints is 1.
