x3270 on Mac Homebrew

Is anyone here in a position to encourage / facilitate Homebrew on Mac to move x3270 on from 3.6ga5 to 3.6ga8? Any reason not to? Thanks, Martin Martin Packer zChampion, Systems Investigator & Performance Troubleshooter, IBM +44-7802-245-584 email: martin_pac...@uk.ibm.com Twi

Re: Linux address space on z/OS 2.4

Three I can think of straightway: 1) No Linux sysproging 2) WLM workload management 3) Proximity to the data I think it’s going to be VERY interesting to see what architectures and operational regimes people come up with. Cheers, Martin Sent from my iPad > On 25 Jul 2019, at 11:22, Jake

Re: DB2 v12 DSN1DBM1 Address space

It’s probably MEMLIMIT - which governs VIRTUAL Storage. And it will be in GB. If that’s what Db2 V12 Installation says, you’d better make sure it has it - whether through JCL or exit or PARMLIB or whatever. But Db2 will only take what it needs - with the proviso that you can tune what it needs.

Re: Sort in a multitasking address space

. Oh... 3) Manage the virtual and real memory appropriately. So, yes, I think multiple tasks invoking ICEMAN in a single job step can be done. Cheers, Martin Martin Packer zChampion, Systems Investigator & Performance Troubleshooter, IBM +44-7802-245-584 email: martin_pac...@uk.ibm

Re: GIT z/OS - ftp to mainframe - record length issue

BTW on the Mac there are at least 3 other options: Python In-built Apache/PHP Filezilla I use option 2 most of the time, option 3 occasionally. Cheers, Martin Martin Packer zChampion, Systems Investigator & Performance Troubleshooter, IBM +44-7802-245-584 email: martin_pac...@uk.ibm

OK; I'll bite: Why not run z/OSMF? But if you prefer to exercise your XSLT skills... :-) Cheers, Martin Martin Packer zChampion, Systems Investigator & Performance Troubleshooter, IBM +44-7802-245-584 email: martin_pac...@uk.ibm.com Twitter / Facebook IDs: MartinPacker Blog: h

Re: [EXT] Re: zOS 2.4 migration guide

I’m not really claiming to troubleshoot this but I wonder - based on your EXCP count comment - what JVM heap specification people (you) are running with. I wonder if it’s garbage collecting to death. (I’d also observe Liberty Profile has a generally good reputation for being lightweight and

Re: OOCoD experiences?

Not to disagree but I still would love to see SMF 113 (and other instrumentation) from around a, what shall we call it?, "episode" :-) .I think the footprints in the sand will be interesting. But I think we digress quite a long way from OOCoD. Cheers, Martin Martin Packer zChampio

Re: APAR OA58438 (was Re: Planned ESQA change and HealthCheck)

Interesting. And no I didn’t know about it. Question: At what stage does the ESQA into ECSA check wave a red (or orange) flag? Cheers, Martin Sent from my iPad > On 3 Oct 2019, at 22:34, Mark Zelden wrote: > > On Thu, 3 Oct 2019 16:18:32 -0500, Mark Zelden wrote: > >> If you are running
