Most of this information is available to z/OS program via the CSRSI callable service. https://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.ieaa100/CSRSI_Description.htm https://www.ibm.com/support/knowledgecenter/SSLTBW_2.2.0/com.ibm.zos.v2r2.iead100/iead100476.htm How to really tell for a particular piece of software? Well, being a very old time, low-level, sort of person, I'd likely run the software (or the key validation part if that is separate) under a program I would write which would use the PER hardware to do an instruction trace. Figuring out how to do this is an exercise (in futility?) left to the reader. As others have said, doing this would most likely violate your licensing agreement, even if it is possible. It would be no different from disassembling the code and simply zapping the license check to return "valid". Many vendors are now making it possible to get emergency keys via a web portal so you don't need to actually talk to a human immediately. If getting a D.R. key is a problem, that is a vendor customer support issue. I'd basically tell them "fix it or I will do my best to replace all your products." I understand the need for keys due to "bad" customers (not paying or paying late), but I still dislike keys. I loved how one book publisher did their DRM. They would take an order from you and you'd get a download URL for the book. It was customized with your name, a serial number, and a note at the back that they paid if told about piracy of their material. So you really needed to trust anybody you "gave" the book to. > Thanks. > > Anne R Adams, CISSP > DTI, Systems Engineering > Sr. Mainframe Services Analyst > 302.298.3196 > > -- Unix: Some say the learning curve is steep, but you only have to climb it once. -- Karl Lehenbauer Unicode: http://xkcd.com/1726/ Maranatha! <>< John McKown ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
