• IS managers who need to merge their UNIX utilization data with mainframe utilization to perform chargeback across the enterprise
• Organizations in the process of "downsizing" from Z/OS to UNIX that wish to monitor the transition for the purpose of cost justification

SCSU and SCS consist of a UNIX resident record creator/harvester and a  costing/reporting component. The difference is, for SCSU the costing/reporting component resides on a mainframe platform and KIM SCS resides on a PC platform.

The UNIX component provides shell scripts and conversion programs to harvest the data and translate it into a format that is readable by the Z/OS costing modules or directly into KIM SCS.

The following detail resources may be tracked and related back to a user name:

• Connect time in seconds
• Print usage—file size in bytes, number of copies and priority for each print request
• Disk usage—may be in either detailed or summary format. The detail format records device names and file size in bytes for all files on the system. The summary format records the disk usage in blocks per user on each device
• Processor utilization—tracks CPU time, memory usage and disk blocks used for each process

User information may also be summarized over a collection period by:

• CPU time (prime and non-prime)
• Memory usage (prime and non-prime)
• Connect time (prime and non-prime)
• Disk blocks used

The costing/reporting portion of SCSU and SSC use an internal translation table to equate user information to valid account numbers. Exit points are provided if a more extensive look-up scheme is required.

COMMON Rate Table – this table allows the system administrator to set resource rates for all of the Charging Systems (CCS, ICS, DBCS, SCSU, IDCS, SCSW and VMCS) from one location.

Table maintenance may be performed through the the KOMAND Information Manager (KIM) running on a Windows XP or above.

The main output from SCSU is in the form of debits summarized to the account level. These debit records may be input to KOMAND/FMS to be combined with other enterprise charges on a consolidated invoice. The option exists to display UNIX charges as a single line item showing total transaction charges or as multiple line items based on UNIX transaction charges by resource. This option may be selected on a customer account basis, showing only the detail requested by each customer. It may also be directly inputted into KIM SCS for costing and reporting.

If desired, an optional detail audit file providing statistics on each transaction processed may be produced by SCSU. Transactions may be charged by resources consumed, a "flat-rate" per transaction, or a combination of the two.

Any field on the input record may be used to apply "special" costing options to the transaction. These options are as follows:

• Free – track the resource consumption, but do not apply a charge
• Drop – do not charge or track this transaction
• Extra – apply a surcharge to basic resource charges
• Fixed – apply a flat rate charge rather than charge by resource consumed

Up to three levels of shift accounting may be applied to standard workdays. Weekend and holiday differentials are also supported. Shift/weekend/holiday multipliers may be applied to the entire transaction or to specific resources within the transaction.
