About UCF members

Your entries can:

• Override the Job Optimizer default processing

• Perform event processing

• Change virtual input/output (VIO) from one name to another

• Identify an esoteric disk or tape

You can create multiple UCF members within a control data set. However, you can have only one active UCF member in a BatchPlex at any time.

While a UCF definition provides a default level of processing options for Job Optimizer, you can override UCF definitions with JTL statements. You cannot use UCF definitions to override existing splitting constraints or data constraints.
