Maximum number of Variable Databases to be defined

The maximum number of IOA variable databases to be defined.

• Maximum: 9 digits.

Average number of columns per Variable Database

The average number of columns for each IOA variable database.

• Maximum: 9 digits.

Data Comp

Data component of the Variable Database Columns 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 IOA with the contents of the primary Variable Database Columns file. Use of the dual file provides data recovery capabilities if the primary Variable Database Columns file becomes damaged or inaccessible. Valid values are:
• Y – Allocate a dual (mirror) image Variable Database Columns file.
• N – Do not allocate a dual (mirror) image Variable Database Columns 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 Variable Database Columns file.
• N – Continue execution if a nonrecoverable I/O error occurs while processing the dual (mirror) image Variable Database Columns file.
• DUALST – Whether IOA 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. Valid values are:
• Y – Perform timestamp checkpoint processing.
• N – Do not perform timestamp checkpoint processing.

Index Comp

Index component of the Variable Database Columns 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 IOA with the contents of the primary Variable Database Columns file. Use of the dual file provides data recovery capabilities if the primary Variable Database Columns file becomes damaged or inaccessible. Valid values are:
• Y – Allocate a dual (mirror) image Variable Database Columns file. BMC recommends that you do not use a dual file for the Index Component.
• N – Do not allocate a dual (mirror) image Variable Database Columns 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 Variable Database Columns file.
• N – Continue execution if a nonrecoverable I/O error occurs while processing the dual (mirror) image Variable Database Columns file.
• DUALST – Whether IOA 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. Valid values are:
• Y – Perform timestamp checkpoint processing.
• N – Do not perform timestamp checkpoint processing.
