As the author of such software, let me confirm what others have said: each vendor does things its own way -- or perhaps not at all. CA has a central "server" program for administering licenses; the software I am responsible for has the licensing embedded in the program itself.
The exact technology is proprietary and a trade secret. To say "we do X and Y and Z" would be to facilitate its defeat by a dishonest customer. [And please, let's not start the whole "to key or not to key" discussion again. Vendor keys are a fact of life. Yes, they can be a PITA. Most customers are honest -- beyond honest to the point of paranoia -- but a few are not. And honest customers sometimes make honest mistakes.] Charles -----Original Message----- From: IBM Mainframe Discussion List [mailto:[email protected]] On Behalf Of Peter Sent: Sunday, February 25, 2018 3:55 AM To: [email protected] Subject: Re: Product license key program Generally which assembler macro or program sets the expiration ? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
