Data policy definitions

Data policy definitions are powerful tools for managing optimization of a large number of entities in one centralized location without requiring JCL changes. Data policy definitions are composed of two parts:

• One or more selection criteria
• Performance options

The first part defines one or more selection criteria. Data Optimizer supports a robust set of selection criteria that includes

• File type (VSAM, non-VSAM, or both)
• Data set name
• Job name
• Program name
• Step name
• Procedure step name
• Data definition name (DD name)
• SMS data class name
• SMS storage class name
• SMS management class name
• Security product group ID
• Security product user ID
• Execution job class
• JES3 MAIN CLASS name
• Time of day

These criteria can be specified independently or in combination to accurately define the entity to optimize. Wildcard characters are supported for the specified values.

The second part of the data policy definition comprises the performance options to apply to the selected open request. For a complete discussion of creating and maintaining data policies, see Managing-data-policies.
