Re: ZPDT usb issue after lunux update.

Is this issue not analogous to "I made changes on my z/OS system, and now some critical software product is broken?" In that case, you would use SMP/E or volume backups to go back. Isn't linux essentially the same (only different)? For my Linux desktop (Ubuntu), with the package manager

Re: Does JZOS DFSORT get offloaded to a zIIP?

JZOS does have native code (not byte code) that is part of the JVM which is zIIP eligible. The JZOS DFSORT wrapper spawns DFSORT in a separate process, which is not part of the JVM and is therefore not zIIP eligible. Kirk Wolf Dovetailed Technologies http://dovetail.com On Fri, Oct 14, 2016

Re: Implementing ICSF - FOTS1949 PRNG is not seeded

Right. I've never seen this particular error caused by a missing CPACF feature. More likely either ICSF is not started or the correct userids do not have access to the necessary ICSF features via SAF/RACF. Kirk Wolf Dovetailed Technologies http://dovetail.com On Wed, Oct 19, 2016 at 10:13 AM

Re: TSO Setup on SSH

There are a bunch of pieces that I would have to externalize; maybe some day. I don't really find x3270 all that objectionable. Its fairly easy to customize and the scripting works fine. Granted, I don't use it that much; most of my z/OS work is from a shell. Kirk Wolf Dovetailed Technologies
