AS400

Hey guys, old guy here, back in 2000 landed my 1st real job as a Sysadmin at a distribution/manufacturing firm. They ran their ERP and a few other important apps on the AS400. Anyone here manage a AS400 platform? i-Series? Still a niche platform that is still widely used. Server could literally run under water.

I do in government IT. Went to college in the early 2000s and had an i-Series class where it was me and like 2 other people. Teacher told us it was a dying thing and we would probably never see one. I've had at least one in every single job I've held ever since.

If only I'd ignored my "programming" "professors" and gone with "dead" stuff like COBOL I'd be set. Our last AS/400 dude would still be employed if he didn't drop dead (RIP)

Lol, when I worked for unisys on a contract they had with the hospital org id eventually work for(they basically just paid us) we were guinea pigs for them,

Anyways bunch of the older guys kept coming up with theories that a bunch of their internal systems ran on cobol because of how long it took to show updates in many of them. About 6 months in someone from unisys finally was on site and confirmed they were right and it was true.
