Specify values for the parameters shown in the following table to calculate the required space allocation for the Variables Definitions file.
Note: When specifying values for parameters or subparameters that include both unit and volser fields, you must either define both the Unit and Volser fields, or leave both of them blank. Do not enter a value for only one of them.

Parameter
Description
Maximum number of groups to be defined
The maximum number of groups to be defined.
Maximum: 9 digits.
Average number of models variables per group
The average number of models variables per group.
Maximum: 9 digits.
Data Comp
Data component of the Variables Definitions file. This parameter has the following subparameters:
DUAL – Whether dual (mirror) image processing is implemented. The contents of the dual file are kept synchronized by Control‑M/Analyzer with the contents of the primary Variables Definitions List file. Use of the dual file provides data recovery capabilities if the primary Variables Definitions file becomes damaged or inaccessible. Valid values are: — Y – Allocate a dual (mirror) image Variables Definitions Report List file. — N – Do not allocate a dual (mirror) image Variables Definitions file.
DUALM – Whether execution terminates if a non-recoverable I/O error occurs while processing the dual image file. This parameter is only relevant if dual image file processing is implemented. Valid values are: — Y – Terminate execution if a nonrecoverable I/O error occurs while processing the dual (mirror) image Variables Definitions file. — N – Continue execution if a nonrecoverable I/O error occurs while processing the dual (mirror) image Variables Definitions file.
DUALST – Whether Control‑M/Analyzer performs timestamp checkpoint processing to ensure that the primary file and dual image file are fully synchronized. Enabling this option ensures greater data integrity at the expense of increasing I/O processing overhead. — Y – Perform timestamp checkpoint processing. — N – Do not perform timestamp checkpoint processing.
Index Comp
Index component of the Variables Definitions file. This parameter has the following subparameters:
DUAL – Whether dual (mirror) image processing is implemented. The contents of the dual file are kept synchronized by Control‑M/Analyzer with the contents of the primary Variables Definitions file. Use of the dual file provides data recovery capabilities if the primary Variables Definitions file becomes damaged or inaccessible. Valid values are: — Y – Allocate a dual (mirror) image Variables Definitions file. BMC recommends that you do not use a dual file for the Index Component. — N – Do not allocate a dual (mirror) image Variables Definitions file.
DUALM – Whether execution terminates if a non-recoverable I/O error occurs while processing the dual image file. This parameter is only relevant if dual image file processing is implemented. Valid values are: — Y – Terminate execution if a nonrecoverable I/O error occurs while processing the dual (mirror) image Variables Definitions file. — N – Continue execution if a nonrecoverable I/O error occurs while processing the dual (mirror) image Variables Definitions file.
DUALST – Whether Control‑M/Analyzer performs timestamp checkpoint processing to ensure that the primary file and dual image file are fully synchronized. Enabling this option ensures greater data integrity at the expense of increasing I/O processing overhead. — Y – Perform timestamp checkpoint processing. — N – Do not perform timestamp checkpoint processing.
