Step 5.1 – Active Balancing File-Space Calculation
Specify values for the parameters in the following table to calculate the required space allocation for the Active Balancing 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.
Table 135 Calculating the space allocation for the Active Balancing file
Parameter
Description
Number of rules invocations per day.
The number of rule invocations per day.
Maximum: 9 digits.
Number of days invocations data is to be retained
The number of days that the invocations data is to be retained.
Maximum: 9 digits.
Data Comp
Data component of the Active Balancing 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 Active Balancing file. Use of the dual file provides data recovery capabilities if the primary Active Balancing file becomes damaged or inaccessible. Valid values are: — Y – Allocate a dual (mirror) image Active Balancing file. — N – Do not allocate a dual (mirror) image Balancing 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 Active Balancing file. — N – Continue execution if a nonrecoverable I/O error occurs while processing the dual (mirror) image Active Balancing 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.
Main Data
The primary data component.
This parameter has the following subparameters:
Unit type – The unit type to which data should be allocated.
Volser – Up to six volsers can be specified.
Dual Data
The dual data component.
This parameter has the following subparameters:
Unit type – The unit type to which data should be allocated.
Volser – Up to six volsers can be specified.
The space requirements are calculated based on the values you specify.
To apply the allocation that has just been calculated, type Y in the Use this space allocation in subsequent installation steps ? field, and press Enter.
