Re: [EXTERNAL] Re: I knew Cobol 6.3 takes more resources to compile than 4.2 but should I be concerned about how much?
On an lpar with 25g of memory we run the COBOL 6.2 compiles with a region of 512M. This is from a program that has well over 25,000 lines of code. Had OPT(0) set plus lots of debug stuff turned on.

I'm going to take a leap and say that the overhead of the paging could cause extended run time. One of the things we have found in doing compiles is to insure you what sized the SYSUTx datasets. In our case we are using SPACE=(CYL,(50,15)) across all 15 datasets. As others have said the compile uses more memory and uses more CPU compared to the COBOL 4.

Re: Trying to understand SMF30_RAXFLAGS
You're right of course. Other systems count bits the other direction. You can make an argument for either approach. - 0 as the high bit corresponds to how we generally represent binary integers, with the high order bit on the left. - 0 as the low bit gives you consistency across 8, 16, 32 and 64 bit operands, and makes the bit numbers correspond to powers of 2.

IBM also explicitly warns about possibly significantly increased CPU usage, but I think I remember they did say that was (mainly) for the advanced optimization. If you are using OPT(0) that shouldn't add to CPU vs V4.2. Are your CICS compiles using the CICS co-processor in the compile step or the CICS pre-processor utility? Ours still use the preprocessor for both CICS and for DB2 and for combinations of CICS and DB2. It's possible that would make a difference if you are currently using the co-processor.

SYSLOG port usage
I have been wandering in the wilderness of unix syslogs under z/OS and have been unable to find a definitive answer to the following question. Does z/OS SYSLOGD daemon support TCP protocol connections for incoming messages from other hosts?? -- Here are the gory details. 1. A DS8884 - and we want to send syslog information to the syslog server on z/OS (v2.4) 2. Adding the IP address to the syslog configuration of the DS8884 'works' but the connection does not activate or work under 'test'. The DS8884 does not allow selection of the protocol (TCP or UDP). 3. IP tracing shows incoming packets on z/OS with TCP protocol port 514. Those packets are reset rejected. 4. Documentation says that UDP 514 is the default for syslog traffic between hosts. 5. There was documentation for TCP 1468 being a well known port for TCP protocols for syslogd. I have no clue if this is possible on z/OS.

Based on what I read in the z114 technical guide, I thought that unless the machine was running in an ensemble mode, the HMC just acted as a remote management console for the SEs. Does the HMC have extra features that the SEs don't? I also have an IBM TS3200 tape library (one of the small 4U rack mount units) that I got broken and repaired. I'll have to see what kind of controller I would need for it.

(Not sure.) I'd really like to get my hands on z/TPF. All of the other major IBM OSes have either ADCD releases, or 24-bit predecessors that are open source, so you can get some experience playing around with them. z/TPF has nothing, and I have never even seen someone do a video, or write an article about it online.

Re: Reliable source for OCO?
I believe that the grammar is corrrect, but the duplication is a typo. Yes, I
meant to include z/OS. I did not know whther OCO applied to z/TPF.
The {{dubious}} template was at the end of a string of footnotes, so I may have
misinterpreted its scope.
The logic manuals that I cited are not for z/foo, but for their S/360
antecedents; the OCO comment was only there to clarify why I didn't cite
current manuals.

Is that editor actually challenging you on your use of commas? :-) And did you
mean to repeat z/VM? I assume you meant z/OS.
If this statement or similar is so important here, what similar statement can
you make that you can back up with an acceptable source? Sometimes if you find
another way to write something it’ll be fine. Perhaps you could write something
like this:
“IBM publicly distributed ‘logic manuals’ that describe ancestors of today’s
z/VM, z/VSE, and z/OS operating systems.”
Then you link to those three logic manuals in your reference.
Also, z/TPF?

This information is thoroughly unofficial. Let’s first run through the highest operating system releases that the IBM z114 supports: z/OS 2.2 (current is 2.5) z/VM 6.4 (current is 7.2) IBM z/VSE 6.2 (current from IBM) [Ask 21st Century Software about VSEn 6.3] z/TPF: officially sometime prior to 1.1.0.14 (current is 2022) Linux: up to SLES 12.x, up to RHEL 7.x Ubuntu no (Canonical started with z12), but current Debian 11 (“bullseye”) should still be OK Summary: With a couple exceptions (such as Debian Linux and z/VSE) current operating system releases are no longer compatible with the IBM z114. I don’t know if this fact is a “veto” or not, but it’s something to be aware of. z/OS, z/VM, z/VSE, z/TPF, and VSEn are licensed operating systems. You’ll need to contact IBM (or 21st Century Software) and somehow obtain a license if you’d like to run any of those. Those releases (except for z/VSE 6.2 and VSEn 6.3) are also Withdrawn from Marketing, so they’d require a very special order if it’s even possible. z/OS and z/TPF require ECKD (FICON-attached) storage, and z/TPF’s storage requirements are slightly more involved than that simple statement. All the other operating systems support “SCSI” (FC-attached) storage. If your z114 includes ESCON ports then that’s another possible option, although there wasn’t a lot of physically small ESCON-attached storage. And ESCON storage is very old now, although it’d probably be inexpensive if you find it. The IBM z114 was the very last IBM Z server that (optionally) supported ESCON without a converter box. FICON-attached (and ESCON-attached) storage is directly attachable: no SAN switch required. You’re quite correct that the smallest FICON-attached storage that IBM ever made was the IBM DS6000 family (a.k.a. DS6800). If you can find one in working condition and suitably configured it’ll support up to 2 Gb/s FICON (“FICON 2”). As long as your IBM z114 has any sort of working FICON ports that should be fine since even the FICON Express8S adapters can negotiate down to 2 Gb/s. A minority of IBM z114 machines have only ESCON ports (or occasionally no storage ports at all if they were Coupling Facility machines), or the FICON ports aren’t working for some reason. That’d be bad, although if it has both ESCON and FICON that could be useful. (An ESCON-attached tape drive, for example.) Hypothetically you could start the z/OS Customized Offerings Driver (COD) Version 3.1 without FICON-attached storage available (from the HMC DVD typically), but that probably wouldn’t be too exciting except as a basic machine test. Speaking of which, does this z114 include a working HMC? z/OS, z/VSE, z/TPF, and VSEn also require at least one general purpose processor (CP) on the machine, subcapacity or otherwise. In other words the machine needs to be an A01 capacity model or higher for those operating systems. It was possible to configure a z114 without CPs. The z114 included a minimum of 8GB of usable memory, so memory shouldn’t be a problem for hobbyist purposes. Other engine types (IFLs, zIIPs, ICFs) are less interesting but can be nice to have, particularly the IFLs I’d say. If the seller says “Oh, it’s a M05” or “It’s a M10” (or 2818-M05/2818-M10), that probably refers to the hardware model. There is a M05 capacity model, i.e. z114 machines configured with 5 CPs set to the “M” subcapacity level. This M05/M05 can be confusing if you’re trying to figure out what you’re getting before you get it, so just try to clarify that point. The 2818-M05 (hardware model) is a single drawer machine, and the 2818-M10 is a dual drawer machine. For power draw/hobbyist purposes the single drawer configuration is likely preferable, although I suppose if you’re very careful and know what you’re doing you might be able to “field convert” a M10 to a M05. I also suppose that the M10 adds some redundancy, so if something breaks or is broken you’re slightly more likely to be able to soldier on. For FC-attached storage, officially (and probably technically also) you’ll need a suitable SAN switch in the loop. I see a used IBM 2498-B24 (SAN24B-4) SAN switch on eBay for $49 or best offer, and that’d probably get the job done very nicely since it supports all the relevant FC line speeds you could encounter. Although you have to hope for a high enough firmware level perhaps since the z114 was introduced after that SAN switch. If you embark on this project, good luck!
Re: HS student with question about small mainframe DASD
