Re: Greg Dyck
I was fortunate enough to work with Greg on an almost daily basis in the
'90s-early '00s. Of course, work with = {argue, fight, collaborate, design,
code, etc.} on a number of projects, mostly digging into concurrency/throughput
issues in the BCP. He was the professor's professor with regards to mainframe
software development, certainly in the nitty gritty of the operating system.
Just a look at his patents will tell you that:

I would expect that this version is the one to get if you want to develop software: https://www.ibm.com/docs/en/zdt/12.0.5?topic=personal-edition Personal Edition ZD Personal Edition enables a single user to run an IBM® Z distribution on a personal computer. ZD Personal Edition can create an environment for mainframe application demonstration, development, testing, and education without Z mainframe hardware. It enables z/OS®, middleware, and other z/OS software to run on Intel and other compatible computers. If you go to this page (https://www.ibm.com/products/z-development-test-environment/pricing), you can start the purchasing process.

The legal question is: is developing a program to be distributed as open source software considered the development of a commercial product? I am not a lawyer, but I've dealt with software IP legal issues for many years. "Commercial Product" is a term that is typically defined within a contract or licensing agreement and _usually_ is something like: "Commercial product means a product, such as an item, material, component, subsystem, or system sold or traded to the general public in the course of normal business operations at prices based on established catalog or market prices." A "plain reading" of the above statement (in my legally _non-authoritative_ opinion) would not preclude development of open source software, as such software is freely available; it is neither traded nor paid for. Of course, that statement is not from the Learner's licensing agreement. It would be interesting if someone could find the exact language.

Rant of the Day - First World Problems
Just figured I'd do the LISTSERV equivalent of primal scream therapy. One of the pleasures of Google is the ability to get help on almost anything IBM mainframe related by searching for something like: TSO REXX POS and you'd get back a pointer to the page in the online library to the POS function within the first five or so Google hits. Given that the z/OS 2.1 doc has been out there for a very long time, almost all of the "hits" refer to the z/OS 2.1 knowledge center. IBM took down all these books in the last couple of days and now all of these hits have been turned to $hit: Documentation for z/OS V2.1.0 is no longer available in IBM Knowledge Center. While the product version and release remains in service, you can find information in the following formats: Individual PDFs for downloading: https://www.ibm.com/servers/resourcelink/svcoo100.nsf/pages/zosv2r1-pdf-download?OpenDocument z/OS V2R1 Adobe Indexed Collection (all PDFs with full text search via the free Adobe Acrobat Reader): http://publibz.boulder.ibm.com/zoslib/pdf/zosv2r1pdfcollection.zip IBM Knowledge Center plugins for downloading (for use with IBM Knowledge Center for z/OS): http://publibz.boulder.ibm.com/zoslib/SSLTBW_2.1.0_4KC.jar. For information about current releases of this product see http://www.ibm.com/support/knowledgecenter/SSLTBW/welcome. More information and resources are available at the IBM z/OS Internet Library: https://www.ibm.com/servers/resourcelink/svcoo100.nsf/pages/zosinternetlibrary?opendocument. Now, this isn't IBM's fault. However, taking the same search to the z/OS 2.2 KC main page gives nothing of value for someone looking for the POS (ironic, huh?) function (the search was TSO REXX POS): - The TSO command environment - Host command environments for z/OS UNIX processing - TSO commands, CLISTs, and REXX EXECs - Using TSO subcommands from a TSO CLIST or REXX exec - REXX ADDRESS TSO support requirements Here's Google's #1 hit (that's as far as you have to go) for TSO REXX POS: POS (Position) - IBM https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2.1.0/com.../pos.htm POS (Position) z/OS TSO/E REXX Reference SA32-0972-00 ... (See also the INDEX and LASTPOS functions.) Returns 0 if needle is the null string or is not found ... To curtail a possible rathole on this discussion, please don't suggest adding "z/OS 2.2" to the Google search. It doesn't help. The Googler simply returns a similar set of hits and says it couldn't find "2.2". POS (Position) - IBM https://www.ibm.com/support/knowledgecenter/en/SSLTBW_2...ibm.zos.../pos.htm z/OS TSO/E REXX Reference ... returns the position of one string, needle, in another, haystack. (See also the INDEX and LASTPOS functions.) Returns 0 if ... Missing: 2.2 < weird for the most likely hit, no?

Sharing across two sysplex
Caught this on the newsgroup, not the LISTSERV: -- jean.b...@ca-attica.fr Hello. We are in the process to separate our current SYSPLEX in two : 1. for the production 2. for the dev/qualifications. A. Can we use an unique TWS controller to Schedule jobs on two ? B. Can we use RACF RRSF to propagate our pwd over IP between them ? C. Can we share dasd (write one side at a time, not pdse) with GRS (not MIM) ? Many Thank's - Answers: A. Yes, but there are recovery considerations. Have a look at http://ibmsystemsmag.com/mainframe/administrator/tivoli/all-schedules,-all-the-time/ B. Yes, but there are operational differences. Have a look at http://www.redbooks.ibm.com/abstracts/sg248041.html?Open C. That's a nuanced question. Can you share DASD between sysplexes? Sure. Can you count on the data on the DASD being maintained with integrity with only GRS, probably not. Without something like MIM, you will need to use some other form of serialization that spans the sysplexes. The only thing I'm aware of is to use hardware RESERVE/RELEASE, which is fraught with its own set of management issues.

Re: Delaying response to a message
> Is there a maximum number of outstanding WTORs allowed? How long does a > message token last. There are two CONSOLxx parameters, RLIM and RMAX, that govern WTOR and REPLY behavior. These can be dynamically changed via the CONTROL M (K M) command. RLIM sets the REPLY LIMIT, number of WTORs that can be outstanding at any time. If there are RLIM WTORs already outstanding, new WTORs will wait for the count to reduce to below RLIM. Programs with certain attributes can breach RLIM and approach RMAX. If the system exhausts all the REPLY IDs available to it (systems reserve the IDs in chunks), it will then serially reuse REPLY ID 0. If REPLY ID 0 is already outstanding, a subsequent WTOR will wait for ID 0 and the system will issue IEA557A. A WTOR will "last" until there is a valid REPLY command for that ID or the program requesting the REPLY terminates.

CPF was added in MVS 4.1.0 (if I recall correctly) - many years after the advent of the SSI. I wrote big chunks of the SVC 34 processing for CPF (back in the 80s...). There is nothing in the operating system, nor the SSI, that forces a subsystem to declare or use a prefix. Also, there is nothing requiring an invoker of the Command Prefix Facility actually be a subsystem. Any program that meets the authorization requirements can do so. Additionally, CPF supports command prefixes that are greater in one character in length. There is an example in the doc that shows how to programmatically set up a prefix that automatically routes a command to execute on a particular system, so you don't have to use the ROUTE command. http://pic.dhe.ibm.com/infocenter/zos/v2r1/index.jsp?topic=%2Fcom.ibm.zos.v2r1.ieag300%2Fmccpf.htm Scott Fagen Chief Architect - System z and Workload Automation CA Technologies -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN

I'm pretty sure that IBM documents how to do this somewhere because who the frack screwed up my control blocks is a frequent SSI problem. Forensically, it would appear that someone(s) on the SSI are changing the command text (augmenting the command) and changing the issuing console id to zero (I don't believe you can alter the console name to INTERNAL). It's not clear to me why you'd expect a command response to show up on a different console from the one issuing the command (other than by MSGROUT, as pointed out elsewhere). A way that you might capitalize on this behavior is to assign the INTIDS attribute to the consoles where you want the output to go. Using INTIDS says, I want all messages routed to console id 0 to come to here.

Re: CFCC memory requirements

Dump space and size of the control code isn't suggested - at least the last time I ever looked at it. I stand corrected. The IBM recommendation for dump space can be found in MVS: Setting Up a Sysplex. From z/OS R12: You can define only one dump space in each coupling facility; however, that dump space can contain several structure dump tables. IBM® recommends that you specify 5% of the available storage in a coupling facility for dump space. If you do not specify any coupling facility dump space, none will be allocated and no structures in the coupling facility can be dumped. Not only that, while IBM tries to keep CFSIZER accurate, as I'm sure some members of this list could attest to, it has not been the most reliable tool over the years and is not an officially supported either. Reliable as in not available all the time or reliable as in gives wrong answers? If the latter, it would be odd, as last I knew, the application behind the webpage actually asked a current CF what the right size should be given the user's input.

Re: ENF 54 (SDUMP event)
Wayne Driscoll said: snip Having 2 API's, one internal, one external has a large number of negative consequences, including increasing maintenance effort, because if there is a defect, both API's have to be investigated, and possibly modified and the increased testing requirements, including ongoing regression testing. /snip It all depends on how you define API. Is the interface the parameter list and the linkage to the service or is it the executable macro one uses to invoke the service? I'd argue that it is not always clear or consistent for z/OS. Obviously, the back end service routines can't figure out if they were called by code generated by a macro or hand cobbled by a developer. There are clearly cases within z/OS where the BCP developers have access to a greater variety of parameters to the same exact linkage and back end routines for a number of system services. There is no technical reason to not provide a mapping and executable macro (in SYS1.MACLIB?) for the unwashed masses and separate macros (in an internally accessible maclib, not shipped with the product) for the Priests of the Temples of Syrinx that both wind up invoking the same back end code.

Re: Remove a system from a SYSPLEX but keep it in the GRS ring
It can be done, you need to define and connect CTCs between all the non-sysplex system(s) and the sysplex systems (see GRSCNFxx http://publib.boulder.ibm.com/infocenter/zos/v1r12/index.jsp?topic=%2Fcom.ibm.zos.r12.ieae200%2Fgrscnf.htm). If you don't fully interconnect the non-sysplex system(s) with the sysplex, there is a potential for creating situations where only a subset (or none) of the complex will continue when a system leaves the ring (you can read about that in Planning: GRS, http://publib.boulder.ibm.com/infocenter/zos/v1r12/topic/com.ibm.zos.r12.ieag400/oldsplx.htm#oldsplx). Adding non-sysplex systems to the GRS complex also turns off a bunch of sysplex-exclusive goodies while those systems are active in the GRS complex, e.g. fully automated recovery from system failures and dynamic RNL changes, implying you have to design and implement local processes to deal with those events.
