You can use the BRCLASS task attribute to specify how a task will respond to an operator-invoked checkpoint. Using repeated assignments to BRCLASS, you can specify that operator checkpoints be allowed at some points in the task and not at others.
You can disallow operator checkpoints by assigning BRCLASS a value of NOBR (the default). You can allow a single checkpoint, and cause the task to be discontinued automatically after the checkpoint, by assigning BRCLASS a value of ONCEONLY. You can allow multiple checkpoints and allow the task to continue normally after each checkpoint, by assigning BRCLASS a value of MULTIPLE.
| Note: | Multiple operator checkpoints are possible only if BRCLASS is set to MULTIPLE for both the job and the task. It is not sufficient to assign MULTIPLE to the task alone. |
The BRCLASS task attribute has effect only if the CHECKPOINTABLE task attribute is TRUE.
