Tuco, I'm a newbie on this list, I've done z/OS programming for fewer years than you have but for longer than z/Linux. You might have seen me on the TCPIP list.
A couple of thoughts - Production means that the agency expects to have the same level of infrastructure and operational support as z/OS. Since it's "On the Mainframe" they're ignoring a huge piece of infrastructure because we made it work for z/OS decades ago. We had z/Linux project go from "skunkworks" to production without resolving all the infrastructure and operational issues. It's not pretty. POR's, backup and recovery, accounting, management, the list of things that you don't take into account are impressive. We've spent several man months already and we're only part way through making our installation fully production ready and billable. I recommend that you push back. The only way I would run z/Linux on the LPAR without z/VM is very early proof of concept, and even then I'm not sure. HTH.

I am new to this listserver community. I am an mvs systems programmer w/ about 30 years experience with ibm mainframe o/s-s (s360 thru z/os), plus about 12 years experience w/ ibm’s UnixSystemsServices/OpenEdition, and its related hierarchical file system (HFS). I have been given a mission to install a Linux o/s on an IFL lpar on one of our Z9 mainframe platforms, and hence have found my way here, to this community. the PURPOSE of the Linux IFL lpar will be to host DB2Connect. The install is going to be standalone directly into the IFL lpar (the governmental agency I work for does not wish to spend any money for a Z/VM license – or for anything else connected w/ this op.). So I’m also going to need a FREE distribution of Linux. So far I have discovered about 3 of these ‘free’ Linuxes: Centos, Debian, and the one available from the marist.edu . question: can anyone offer me some advice on which one I should use (please keep in mind the purpose is to host DB2Connect) ? question: can anyone recommend any good cookbook manuals to use? on my own, I’ve discovered quite a few books out there on the internet, but I would like to save some time and not have to download each one to check it out …. question: anyone have any gp (general purpose, across the board) words of wisdom he/she would care to share? thank you for your indulgence. /s/ tuco bonno graduate, College of Conflict Management; University of Southeast Asia; "I partied on the Ho Chi Minh Trail - tiến lên !!
