Declare the percentage-based threshold policy (PercentageBasedThresholdPolicy)
This policy provides a batch implementation of the ThresholdPolicy interface.
The percentageBasedThresholdPolicy is applicable only if the ThresholdBatchStep is used. It calculates the percentage of the number of error records processed to the total number processed. If the result is greater than the threshold, it forces the job to go into restartable state.
Optionally use the following properties when you declare the percentage-based threshold policy.
Optional properties. The table includes the property name, property value, and property description.
Property Value Description debug true or false (default is false) Enable tracing and debugging on the step minimum_threshold_sample_size Integer value (default is 20)
The minimum number of records to process before checking for threshold breach.
threshold_threshold Double value (default is 0.1) The acceptable percentage of errors.
Procedure
Declare the threshold policy to use in the xJCL as a property of the step as follows:
... <props> <prop name="threshold_policy" value="com.ibm.websphere.batch.devframework.thresholdpolicies.PercentageBasedThresholdPolicy"/> </props> ...
Batch data stream framework and patterns
Develop a simple transactional batch application
Implement the error tolerant step
Declare the record based threshold policy (RecordBasedThresholdPolicy)
