Episode 33 "These Boots Were Made" What’s New Preliminary z/OS 3.1 Upgrade materials Python 3.1.1 zIIP enablemment OA63406 and PH52983 Mainframe - Requires: z/OS V2.5 with PTFs, IBM z16 with microcode. Has both driving and target system requirements, use IBM.Function.ValidatedBoot FIXCAT. Front end: Siging the in-scope artifacts (NUCLEUS, LPA, IPL Text, and SA Dump Text), z16 is not required here although z/OS V2.5 and PTFs are. Back end: Verification of those signed in-scope artifacts. z16 with correct microcode level is required here (with z/OS V2.5 and PTFs). Security set up work is required. Performance - Open Data Sets, Part 2 Follow on, from Part 1 which was physical open and close of data sets as seen by z/OS. This is about Db2 with the notion of logically Open and Closed data sets. Its main role is to manage inter-Db2 read/write interest, for Datasharing efficiency purposes. Two Db2 subsystem parameters have traditionally been used to control pseudoclose: PCLOSET and PCLOSEN. PCLOSEN is gone in V12 with APAR PH28280, as part of a DSNZPARM simplification effort. So PCLOSET would need adjusting down to whatever mimics PCLOSEN - in anticipation of this APAR or V13. Topics - Messing With Digital Electronics Martin explores his experiences with input devices (Stream Decks, Quick Keys, ...) Martin has even built his own input devices: having an RFID card kick off automation, rotary encoders, USB Human Interface Device. On the blog Marna's blog Martin's blogs So It Goes
