Mainframe, MVS and zOS Discussion

Hi,

What is charge back model in mainframes? Are there are multiple type of charge back models available?
Do we have some details about it from vendors and IBM available to us? Google gives some mix answers, but in connection to mainframes how it works? Can you share thoughts please.

What is charge back model in mainframes?

the same thing as in any other environment

the users of IT services are billed

There is NO standard chargeback model on mainframes -- each site designs and implements their own.  As such, chargeback models vary widely.  Many (but not all) will charge for disk usage, tape usage, and CPU usage -- some also charge for storage usage but others don't.  They can be simple or extremely complicated.

Thanks. I understand different sites won't allow to understand their charge back models but are there some example of these charge back models on IBM site?

Or on the site of any other mainframe manufacturer?

I don't really think you understand yet -- charge back is an accounting fiction that some companies use and other companies don't.  Vendors don't really care how the company accounts for the use of their system as long as the company pays for the system -- either up front or in annual payments or monthly payments or whatever.  Googling chargeback model allowed me to find this 9-year-old IBM Powerpoint presentation that might help you:  ftp://public.dhe.ibm.com/software/os/sy ... dology.pdf

But in general hardware vendors (mainframe or otherwise) are not very involved in charge back.  Perhaps you should go find an accounting forum and ask on that?

Thanks for your answer Robert but the ink did not open for me. If you can attach the file or share the link again, may be it will work for me.

it was a bit slow but it worked for me.

The link is a 6-meg Powerpoint presentation.  I think what you're wanting is on one slide:

Thanks Robert and enrico.
