Declaring the percentage-based threshold policy (PercentageBasedThresholdPolicy)
The PercentageBasedThresholdPolicy policy provides a batch implementation of the ThresholdPolicy interface.
Before you begin
The percentageBasedThresholdPolicy policy applies 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.
About this task
Optionally use the following properties when you declare the percentage-based threshold policy.
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_percentage | 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>
