Batch Job and TSO Session Resource Accounting (DAS)
The KOMAND Data Center Accounting System (DAS) is a job cost accounting and usage reporting system for IBM z/OS host systems. It is a robust solution for data center, single and multiple host resource accounting and cost management that provides workload, equipment utilization, and job charging information at levels from the individual job/step through a summarization for the entire enterprise.
DAS accounts for MVS batch, TSO, and started tasks. It allows accounting information to be extracted from the jobname, accounting, or programmer name fields on the job card (or pseudo job card), or through a user exit table look-up. Account numbers may also be assigned to started tasks based on the jobname field.
DAS computes the cost of a job in batch mode by using collected SMF records and optionally in “real time” (On-line Costing) as the job is running using standard operating system exits. If the cost is computed in “real time”, the utilization and costing statistics may be displayed on the batch SYSOUT or on a TSO terminal at logoff time. On-line Costing may be implemented for the entire community or for selected users.
The resources and rates for charging are controlled by the DAS Factor Table. An unlimited number of alternate charging algorithms (Factor Tables) are supported by DAS. Each individual Factor Table allows charging for over 90 separate resources, such as CPU time, tape and disk I/O, print lines or pages, etc. Some other costing options include:
- Shift accounting (weekdays, weekends and holidays)
- Proprietary software charging
- Print not associated with a specific job
- Priority accounting
All DAS functions including execution of batch jobs and maintenance of costing tables may be controlled through batch control statements. Table maintenance administration and reporting may also be performed through the KOMAND Information Manager (KIM) PC user interface product. DAS can also produce an output file containing job costs and utilization for input to the KOMAND Financial Management (FMS) product where it can be merged with other enterprise resource charges to produce consolidated invoices and other financial reports. Customers may also use the resource usage and cost data from DAS to feed their own existing financial billing systems instead of or in addition to KOMAND/FMS.
