Another thing that no one has mentioned, other than my saying "security has gotten big":
Passwords have changed. They can now potentially be mixed case, and can include additional "special" symbols .<+|&!*-%_>?:=. They can even be longer than 8 characters -- IBM calls that Pass Phrases. "How now brown c0w" could be your "password" (pass phrase really) to sign onto TSO. Adoption has been slow. There is some management "if it ain't broke" and some legitimate concerns about session managers and other products that have fixed length fields, upper case their input, translate inconsistently from ASCII, etc. There is also z/OS support for multi-factor authentication. You know, a password PLUS a code from a fob or mobile app. As I said, security is really huge. In the 1990's (a little before your cutoff) my company sold a mainframe-to-PC file transfer product. I don't recall any prospect ever bringing up security. Nowadays the entire product would be out of the question: it was basically a "back door" into a PC that ran with root privileges. "Security" informs every decision -- as well it should (see Colonial Pipeline, Scripps Health, Irish Health, Maersk Shipping, etc.) Charles -----Original Message----- From: IBM Mainframe Discussion List [mailto:IBM-MAIN@LISTSERV.UA.EDU] On Behalf Of Steve Estle Sent: Monday, May 17, 2021 6:42 PM To: IBM-MAIN@LISTSERV.UA.EDU Subject: Best catch up resources for MVS / ZOS Technologies Hello Everyone in Mainframe Land, I've been out of the mainframe world since about 2001, but spent the prior 20 years immersed in that world working with everything from MVS/370 to MVS/ESA and VM, performance and capacity planning disciplines across a variety of situations in the IT Services and consulting spaces. I, am, now as a "IT Infrastructure Engineer- IBM z/OS Mainframe Engineer" after nearly 20 years of other activities (Project Mgmt, entrepreneur, etc) am about to potentially come back into a new mainframe role and I need to catch up as quickly as possible. Any suggestions on ways to fill in the gaps for ZOS, ZVM, hardware, performance, etc? Bottom line I'm looking for that gap education to as quickly as possible get up to speed with changes in platforms since 2001. If prefer to call - all my info is below. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
