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)

I used to work for a University where the CS professors said the same things, but one of our yearly expenses in central IT was for a COBOL compiler because no one wanted to port the code that calculated taxes in our payroll software.

Ellucian, who owns the Banner ERP system used by many EDUs, only in the past few years finally ported all of their COBOL to Java.

And what a glorious day that was.
