Ah, bad or perverse behaviors. Two stand out in my career. -- A data base application was redesigned at the last minute to read the entire data base into memory at startup. The business unit noticed that they were charged for I/O but not for memory use. It was cheaper to occupy virtual storage than to perform reads. So much for common sense.
-- An ISAM application that could have been converted to VSAM--as discussed in a recent thread--was deliberately left to the sluggish vicissitudes of ISAM because of how the client contract was written. Data center would have collected less revenue with a more efficient process. Yuck. . . .

It's based on *peak* four hour rolling average utilization per month -- or, effectively, per subscription year for products that are not Monthly License Charge products. You can set whatever pricing scheme you want, I suppose. Your chargeback system could be based on counting keystrokes (and clicks and taps) on client devices, for example. That keystroke-based approach might even be more closely aligned with actual marginal costs of computing services than some of the chargeback schemes I've seen. In my view a bad chargeback regime is worse than no chargeback regime, and it's quite easy to have a bad chargeback regime. "Bad" here means encouraging perverse behaviors and/or discouraging smart behaviors. -------------------------------------------------------------------------------------------------------- Timothy Sipples IT Architect Executive, Industry Solutions, IBM z Systems, AP/GCG/MEA E-Mail: sipp...@sg.ibm.com ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
