Data Management Utility (DMU)

The Data Management Utility (DMU) provides you with a mechanism to build, update, and merge accounting data for computer-related resources, such as programming, data control, and data entry. This data can then be processed to apply charges, produce reports, and integrate the data into the computer job accounting files.

The Data Management Utility operates by processing input containing utilization and accounting information for computer-related resources, and producing an output file that is used by this product as DOS input. The DMU edits the input and checks for syntax discrepancies that can cause improper processing. Any erroneous data is flagged and a diagnostic message is printed describing the problem. In addition, a database maintenance control report is generated that lists all processing actions taken.

The information the DMU manages includes:

• job or function name
• resource identification
• user identification
• accounting information
• Date
• Utilization
• start time/stop time

The DMU program is written using standard IBM ANS COBOL language. All sorting operations performed by the DMU program are executed using the standard IBM or compatible vendor-supplied SORT/MERGE program via the COBOL SORT verb.

The minimum amount of storage required to execute the DMU program is 1024K bytes plus the amount of core required by the SORT/MERGE program. The maximum amount of storage required varies depending upon the size of the I/O buffers for the SORTWORK data sets.

Note: The Data Management Utility can be found in CAI.CAJRLOAD (SJUTL00).
