Batch Control Algorithms
The following table describes all the system events supported for maintenance objects.
The Algorithms grid contains algorithms that control important functions for instances of this batch control. You must define the following for each algorithm:
The following table describes all the system events supported by batch controls. Note that some system events are batch program specific and as such are not available to all batch controls.
| System Event | Optional / Required | Description |
|---|---|---|
| Error Post-Processing | Optional |
Algorithms of this type are called if the batch process fails to complete due to an error. Multiple algorithms are allowed and are executed in sequence order. Refer to Error Post-Processing Logic for more information. |
| File Upload | Optional |
Algorithms of this type are only applicable to plug-in driven background processes and are used to upload all records for a file. This is a single algorithm plug-in spot. If multiple algorithms are plugged into the batch control, the one with the highest sequence is used. |
| Level of Service | Optional |
Algorithms of this type are called to determine the Level of Service provided by a batch control. Multiple algorithms are allowed. Refer to Assessing Level of Service for more information. |
| Parameter Validation | Optional |
Algorithms of this type are only applicable to plug-in driven background processes and are used to validate batch specific parameters. The algorithm is invoked prior to the select and process records plug-ins. This is a single algorithm plug-in spot. If multiple algorithms are plugged into the batch control, the one with the highest sequence is used. |
| Post-Processing | Optional |
Algorithms of this type are called after all threads are complete. Multiple algorithms are allowed and are executed in sequence order. Refer to Post-Processing Logic for more information. |
| Process Record | Optional |
Algorithms of this type are only applicable to plug-in driven background processes and are used to process a specific record. This is a single algorithm plug-in spot. If multiple algorithms are plugged into the batch control, the one with the highest sequence is used. |
| Select Records | Optional |
Algorithms of this type are only applicable to plug-in driven background processes and are used to define the SQL to use to select the records to process. This is a single algorithm plug-in spot. If multiple algorithms are plugged into the batch control, the one with the highest sequence is used. |
