Re: Converting SAS C to IBM C
Clark: Have you looked at Dignus (http://www.dignus.com/) ? It really makes things much easier. Harry P.S. I use Dignus for my mainframe C/C++ work, but have no affiliation with them. Date: Fri, 15 Oct 2010 10:05:26 -0400 From: clark.k...@asg.com Subject: Converting SAS C to IBM C To: IBM-MAIN@bama.ua.edu I apologize in advance if... 1) This has already been discussed (I did not find it in the archives) 2) This is not the proper forum for this question (but IBM-Main is always a good place to start) We have a number of C programs that need to be converted from SAS to IBM. The reason for this is because SAS has decided to drop support for their C/C++ compiler, so we need to get our code onto a supported platform. When these programs were written (10+ years ago), the SAS compiler was the best one available. Now the IBM compiler has caught up, and may be even better. But it still does not make the conversion any easier. Some of this code is pretty complex, as it makes use of MVS facilities like WAIT and POST, plus much of the code jumps back and forth between C and assembler language. If any of you have been down this road before, could you please point me to some useful resources? There are plenty of IBM manuals, but I was looking for something more like a porting guide specifically for those traveling this path - something that addresses a specific SAS C extension, and describes how to do the same thing in IBM C. Also, my C coding skills are a bit rusty, and I would appreciate a forum or mailing list that provides help day-to-day coding questions, specifically related to the IBM compiler.

Re: Multiprise 3000 - fatal SE problems - help please!
Mike, Here is my opinion in the form of a WAG (Wild Ass Guess): You're barking up the wrong tree. Based on what you describe, your software is fine; the SBC that runs OS/2 is running; your CPC is working; so I don't think this is an SE issue at all. You don't need an activation profile to use the machine, it's more of a convenience. You do need to be able to do a POR, however. After that you can just IPL manually. If the CPC wasn't working you would be reading about it in your hardware log. What you describe is the SE is unable to issue control commands to the CPC and receive returned information. What seems to be missing is control signalling between the SE and the CPC. The SE and the CPC are working and communicating, but control signalling is DOA. You probably have a missing, loose or removed signal cable. Some cables inside IBM mainframes are not what they seem (actually most), IBM sometimes uses connectors that are common in PCs for entirely different purposes. Do not assume, based on physical form factor, that you know what a cable or connector is used for. I'm a design engineer, not a CE so I don't know what cable it would be, but somewhere along the backplane where the OS/2 SBC is seated there should be a cable coming from another card on the same backplane that runs to the part of the frame where the CPC board is. That cable is probably your problem. If the machine was just moved, the cable may have just come loose.

Re: port from z/OS to z/VSE
Steve, You should try to contact Jerry McCarthy at QMSI (je...@cmpg.com). He wrote some amazing code that uses z/OS like PC calls on z/VSE. He coded the internals of QMSI's postal software (CASS software, a replacement for Group I's mainframe) to run on z/OS or z/VSE and it uses PC calls. Initially he used XPCC but found its overhead too high for the performance requirements of his application. He alluded to it on this list in July 2009: http://groups.google.com/group/bit.listserv.vse-l/browse_thread/thread/4c2f5d849ecfe127# The code he ended writing is very clever and one of the reasons QMSI's postal software is so fast.

Re: IBM Software Secure Support via USA Citizens
I think this is being misconstrued. There are caveats in the Stimulus Package (3.4 trillion dollars of spending) requiring that the money not be granted to projects not using resources in the United States. This is fair considering that the money is being spent to stimulate the American economy. I suspect IBM wants to create a supply channel for products and services that is obviously and unambiguously compliant with this so that IBM (and companies that sub-contract to it) is clearly eligible for Stimulus Package projects.

Re: Crazy VSAM question
John, I don’t know the details of your situation so I’m just tossing out ideas here: If the AIX doesn’t have to be upgradable, build the alternate index manually, excluding from the AIX any alternate index entries with low values keys. Depending upon your application, this may even work with an upgradable AIX. You might be able to use the obsolete parameter “KEYRANGES” on your AIX definition to exclude low value key entries on the alternate index. You could use a range of values instead of just low values to indicate an absent AIX key: set aside a range of values that will not occur with a non-absent key. For example, x’00’ followed with a binary timestamp. You could define an exceptionexit (on the Cluster or AIX) and code a work-around within it or at least avoid a lot of application changes. Combinations of the above suggestions. Harry Date: Mon, 4 May 2009 10:37:18 -0500 From: joa...@swbell.net Subject: Crazy VSAM question To: IBM-MAIN@bama.ua.edu A programmer has posed this question to me. My response, so far, has been no way. But I'll ask the truly knowledgeable here. We have a KSDS with an AIX. The data in the field which defines the alternate keys is sometimes unknown and coded as LOW-VALUES (0x00's). Well, this has lead to a problem where the number of base records for the unknown value is often quite huge and exceeds the maximum allowable record size on the AIX. This causes the base record add or update to fail. What the programmer wants is a way to tell VSAM that if the AIX key is 0x00s, that it is not necessary to update the AIX at all. I cannot think of any way to do this.

Re: Old discussion about Windows running on a mainframe ( I brought up)
Platform Solutions, Inc. had this technology and much more. Their technology is now IBM's. Many people accuse IBM of acquiring PSI to stifle competition, but this is a great disservice to the engineers at PSI, particularly former Amdahl engineers, who are now bound to silence by NDAs. http://www.nytimes.com/2009/03/23/technology/companies/23mainframe.html?_r=3pagewanted=2ref=technologyadxnnlx=1237816804-Ls%2021S/ySzdFWiPCcF03qQ IBM may see the virtualization of Windows onto z architecture as strategic; both as servers and workstations and its acquisition of PSI reflects this. From what little Mantissa has disclosed, their approach, IMHO, is inherently flawed. Their SHARE presentation seemed to be little more than an obfuscated discourse on virtualization in general. Even if their approach works, it would have been better, architecturally, to emulate an Itanium for Windows hosting because of the nature of the Itanium’s instruction parallelism. A more sensible approach would be to look at creating a Windows HAL (hardware abstraction layer), or something conceptually similar, that runs on z/Series. Historically, this is how Windows has been made to run on different machine architectures. Of course, cooperative development between IBM and Microsoft would be necessary. Another possibility is to exploit the Infiniband feature of the z/10. This feature is profound in terms of 360-z/series evolution, but has been largely ignored, so far. Infiniband attached external hardware products that expose x86 architecture processors, from Intel or IBM itself (or maybe even Intel Larrabee), is an ideal way to run Windows on IBM mainframes. In the interest of disclosure, I have worked for both IBM and PSI, but the opinions I express here are complete conjecture.

Track this topic Print story Post comment z/VMs get Microsoft rumor By Timothy Prickett Morgan • Get more from this author Posted in Servers, 23rd March 2009 22:34 GMT Whitepaper download - Eight CRM essentials An obscure mainframe software company called Mantissa Corporation bragged last summer on the IBM VM listserv - which is dedicated to virtual mainframe environments - that it was creating a product called z/VOS that would allow slices of a Windows operating system to run atop z/VM, the hypervisor-as-operating system for IBM mainframes. The product was due in the first quarter of this year, and the story of its impending release has been making the rounds. According to a report in NetworkWorld, Mantissa's z/VOS, presumably short for Virtual Operating System, is a layer of software for VM that allows desktop and server Windows operating systems to run in emulated mode atop z/VM. Mantissa - which is based in Birmingham, Alabama, and which is a supplier of report distribution and other tools for mainframes - talked about the z/VOS product at the SHARE mainframe user conference in early March in Austin, Texas. But that was not the same thing as a product launch. We've tried to reach the company for several days, but Mantissa has yet to respond. While IBM and the Linux community for mainframes centered around Marist College in New York have worked to get official mainframe ports done for Linux - Red Hat and Novell officially support mainframes, if you can write a big enough check to get support - there is no native Windows port to IBM mainframes as far as I know. So, the real curiosity is how Mantissa is supporting Windows XP or Vista atop z/VM partitions. According to the company's development blog, z/VOS includes a translation engine that converts native x86 code to its System z equivalent. See how easy that was? As it translates equivalent results - not creating equivalent machine code, mind you - the instruction that is created by z/VOS is stored in memory so it can be accessed the next time the operating system function inside Windows running on the mainframe is asked for again. Since Gary Dennis, Mantissa's chief executive officer and founder - and other we've called - are not answering their phones, it is a little hard to take the company seriously. But if it can indeed deliver a layer of abstraction software atop z/VM that lets Windows desktops and servers run on mainframe iron, the company should probably think about getting someone to answer the phones and maybe a salesperson or two to try to take some orders. If the x86 translation overhead is not too high, this could be a very interesting development - and one that Big Blue would seem pretty keen on supporting, not quashing. ® http://www.theregister.co.uk/2009/03/23/mantissa_windows_on_mainframes/ AT least these people
Re: Virtual Storage implementation
Virtual is one of those overused technical words like interface. For a language with so many words with such subtle meanings, English speakers really do have the lingual facilities to do better than to constantly reuse the same word for different innovations. That notwithstanding, with so many technical implementations being called virtual today, it is sometimes necessary to define which context of virtual you are referring to in any given situation. Once this is established, you must take all the other virtuals that might be bandied about and store them someplace out of mind. That place would be called virtual storage. I hope this clears things up. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
