Re: Goodbye, Farewell and Amen
We run SAP on Windoze with about 200 users online at once. It works reasonably well, and I can't recall when we last re-booted the SAP servers. I know they are shut down over daylight saving changes for some reason, but other than that perhaps the odd tine when applying MS updates. However SAP is a beast and in order to get it to perform it needs to have plenty of devices to spread the i/o over. I do see i/o bottle necks from time to time, and when I persuaded them to move the main database files to a dedicated tray of disks in the SAN things improved markedley. The BIGGEST problem with Windows is that managers (mine included) don't understand that you need to design the server platform. They think you can just sling in any config and it will work. For big systems such as SAP You MUST design the storage subsystem for I/O throughput NOT for capacity..

There are caveats to using any virtualization solution in MS licensing for certain applications, but they are the same conditions as you hit with VMWare. You still need a valid Windows license per virtual appliance, just like you do with VMWare. As John commented, most sites that are into large-scale Windows stuff bought a site license, and you report the license just like you do for deploying it in VMWare. It's just one more Windows instance that happens to be running on unusual hardware. (God, I hate comparing this to VMWare, but it's the clear comparison that Win-weenies get.) Can I just add one caveat. One of the types of licence Microsoft provides is an OEM licence. In the case of a desktop OS an OEM licence is NOT TRANSFERABLE and dies with the hardware its installed on. Generally if you buy a PC it has this type of licence. Other than that, as I said beforem there are very few limits about what hardware you can run the software on. Many solutions also include downgrade rights, so if you buy a current Windows Server 2008R2 licence you could install any previous version you could find the media for, I think probably as far back as NT3.51 Dave
Re: Windows Enabler Appliance on System z Now Available
It's the same as any other virtual environment. At present MS don't limit the hardware platform used. Until recently you needed one Windows licence for each virtual instance of Windows you ran. This has been amended recently and the rules are now more complex. For example if I have read the rules properly if it's a workstation version of Windows and you connect exclusively from a PC running the same version of windows then no licence is needed. For Server Standard you get one instance that can be used for managing one virtual instance. For Enterprise server you get 4 instances per licence.

The appliance has been tested with (and passed) the Microsoft Windows Server Hardware Verification test, and Windows Server 2003 and 2008 virtual machines have been successfully deployed and run applications such as Exchange 2007 and Sharepoint. What is the intended use? The appliance is intended to provide a immediate way for Intel server applications that perform mostly I/O intensive applications to run on System z hardware, and is best suited for server applications such as Exchange or Sharepoint hosting. The appliance does not include licenses for any OS (eg Windows, etc) or the applications to run within the appliance. Based on what IBM has publically shared about System z hardware futures, we see this as a roadmap item that will be expanded and optimized to take advantage of new direct execution capabilities as they become available. We are discussing how enhancements to speed up the emulation could be done with IBM, and will share more as things evolve. How's It Work? It's based on the research with dynamic instruction simulation done as part of the OpenSolaris for System z work and a clean-room x86_64 instruction description. It is (by definition) not as efficient as real iron, but it provides a way for x86_64 applications to be run without adding additional hardware to the data center. What Do I need to Run it? A z10 and z/VM 5.4 or greater. It may work on pre-z10 machines, but it is likely to consume an unacceptable amount of overhead CPU. Both IFL and CPs are supported. How do I get a copy?

Re: ACM award - they deserve it....
In my humble opinion the main reason VMWare (an to a lesser extent HyperV) is popular at present is because it allows bean counters to demonstrate huge instant savings. Where I work we have around 200 Windows servers, many were bought around 5 years ago so will need replacing soone. In general we have a separate server not for performance reasons but more for separation of control and software options. Based on a limited trial I would say we could consolidate 75% of these servers at a rate of at least 10 to 1 using VMWare, and still have enough headroom to loose a physical server with no performance impact. So that's take the 150 lowest loaded servers and replace them with 15 servers running VMWare. To a bean counter that's a 90% reduction in power consumption, a 90% reduction in floor space, and a 90% reduction in hardware support costs.I am sure some think that should also be a 90% reduction in support staff, but of course that's not true. Whilst VMWare is fun to manage, it needs managing and also capacity planning. In practice the reduction is some what less than 90%. . To use the vernacular, a VMWare server will be a fully loaded server with multiple CPU's, lots of RAM, multiple SAN and Network interfaces for load balancing and resilience. In order to fit these in it will be a 2U server and some of our existing are 1U, on the other hand others are 4U... BUT there will be a big saving. Now compare that with zVM. With that you were frugal from day1 so there aren't any savings. So the bean counters can't show cost reductions, so they don't like it utterly blinkered Dave. - Original Message - From: Barton Robinson bar...@vm1.velocity-software.com To: IBMVM@LISTSERV.UARK.EDU Sent: Wednesday, March 31, 2010 3:53 PM Subject: Re: ACM award - they deserve it If you go to conferences such as CMG (Computer Management Group), that has been a mainframe organization (meaning MVS or z/OS) since it started, our VM has never been represented, but VMWare now has many sessions.

Re: Moving on: The University of Maine (System) shuts down mainframe
Richard, I meant to say the perceived cost was less, but its the perceived cost thats important. As you suggest the granularity of costs is also a big factor and is probably one of the major factors responsible for the dearth of servers (Solaris as well as Windows) we have in our Data Centre. Its made a lot worse by the Micro Management and Bean Counter accounting that seems to be endemic in the modern world. If some one has a budget and expects to use it to buy a server, it can be very hard to persude them to use an existing box. Especially as we are local government and this means we loose the money for the server, they can't see that its doesn't cover the real costs which are on-going. I still wonder why IBM did nothing to encourage my employer to keep their mainframe. Perhaps they make more money from the steady stream of Intel boxes that keep coming through the doors Dave G4UGM -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Richard Troth Sent: 05 January 2010 19:34 To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Moving on: The University of Maine (System) shuts down mainframe Dave -- This is ridiculous. Do you really want to start a religious war on the value of Windows ... on this discussion list? To your two points, cost and flexibility, I dig in for further analysis as follows. COST Windows is not more cost effective. It carries a finer grained price point profile than MVS or VM or even most Unix. But it is hardly cost effective (for servers) in any shop bigger than a local funeral parlor. Given the availability of Linux (and before that, low end Unix) even its smaller per-unit charge is at risk. I will abstain from repeating the scalability numbers we all know and love because I am lazy. You get the point. Windows is inexpensive at the start but quite the opposite later. FLEXIBILITY Windows is actually LESS flexible (for servers) when you consider that it cannot run (traditionally) without a mouse as well as keyboard. The very idea is counter to anything like lights out. But that's just one point. What is flexibility? Linux, traditional Unix, VM, and even MVS have so many more knobs to turn than Windows does. And Windows presents more penalty when you start turning knobs than do these other systems. I state this without specific evidence because having heard the horror stories more than once, I have filed the info away: one does not adjust Windows. If you disagree, and the moderator will indulge us, then I will start finding and posting documented evidence. Now to my two points: sexiness and vanity. SEXINESS Windows is familiar. That at a minimum is comfort. It is emotional. Salesmen LOVE when you get emotional. Do you yourself not know Windows enough to drive its menus and figure out some amount of configuration? But menu-driven config does not scale past one or two servers, and then we're back to cost. So perhaps I have stretched and implied that anything salsemen love is sexy. But I did not mean that. Windows really is (my opinion) nice looking. Windows is graphical ... in its very name. (And as I suggested in a prior paragraph, one cannot usually turn off the graphics, which gets us back into flexibility. But I digress.) Graphics are sexy. 3D is even sexier, but who can argue that visual offers more immediate gratification than verbal? Pictures are appealing. VANITY One definition of vanity is a self focus. Windows is an excellent candidate for per-user service. I prefer Linux in that role only to avoid corporate entanglement and closed source bondage, NOT because there is something wrong with the op sys. Windows supports an individual user quite nicely. But for servers ... not so well. I submit to you that many customers have decided on Windows because they only brought in their own experience, and that with the presentation end. Might as well use the vanity mirror in your bath room for the furnace at Odeilo. Another English definition of vanity is triviality or hollowness. (Am trying to avoid the blunt lack of value because I already said Windows DOES have some value.) Using Windows for server service in your data center is vanity. Unless driven by vendor requirements for software that you chose for other reasons than flexibility or scalability, Windows is simply NOT the right choice for that infrastructure. -- R; On Tue, Jan 5, 2010 at 07:57, Dave Wade g4...@dpwade.eclipse.co.uk wrote: -Original Message- From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Richard Troth Sent: 05 January 2010 01:04 To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Moving on: The University of Maine (System) shuts down mainframe Actually, Jack nailed it.

How does VM scale with regards to multiprocessors? In the z/OS world the 1st z/10 engine is like 900 something MIPS and the 60th on the box is something like 359. Does z/VM hosting Linux suffer the same fate? (z/OS per engine pricing actually goes down to compensate for this, z/VM's does not). Marcy I think that is must because, to the best of my poor grasp of things, this is an effect of the __hardware__, not the software. I.e. interference between the CPUs for the memory bus and inter-CPU bus snooping and communications. E.g. when a CPU updates a location in memory, every other CPU must be sure to update or flush their cache if it includes this location in it. This slows down the CPUs. That is why it is good for work to not share memory, if possible. I would have said it's a combination of software and hardware. If zOS is still any thing like MVS memory contention will be a major issue. Every task shares the same low storage area which is spinlock protected, and when you are stuck in a spinlock you waste CPU. I note that the latest zOS Troubleshooting course still mentions spin locks... http://www-304.ibm.com/jct03001c/services/learning/ites.wss/gb/en?pageType=c ourse_descriptioncourseCode=R2MEDGGB or http://tinyurl.com/zosdebug Linked with the way IBM price that would probably seem to be the case. Contrast that with zVM. When you run multiple Linux instances each Linux instance has separate non-shared memory running under the SIE microcode. Each instance is really well isolated from its neighbours, which is a pain when you want to share data, but it really allows you to get the best from a box with lots of CPUs. So whilst I can't believe there isn't any multi-processor effect, I would expect it to be much less than on MVS. -- Trying to write with a pencil that is dull is pointless. Maranatha! John McKown Dave P.S. An afterthought, since I note that the original question mentioned pricing. Since when did any one expect IBM (or any makers) pricing to make sense. DEC/Digital went there years ago when it tried to have different prices for the same ALPHA boxes depending on if they were running Windows or UNIX. That's why we have all this non-sense over IFLs. In DECs case folks running work under UNIX could move to LINUX or other vendors UNIX. In IBMs case if you want to run zOS or zVM there is only one player in town.

However if you want multiple CPU support you really need a 64bit system underneath. It's legality typically raises some questions, particularly when people want to run current levels of System z software on it. It shouldn't as in general it is not legal to run current versions zOS or zVM on Hercules. All questions of legality of current OSs need to be discussed with you IBM representative. There are significantly older levels of mainframe software that the Hercules maintainers claim are unencumbered by such things. As far as I know IBM has never tried to claim otherwise, and one or two users of Hercules actually have copies of MVS3.8J that were supplied to them by IBM. However most of this is really only of Historical Interest. Whilst the OS's are freely available much of the supporting software such as modern compilers, editors and support software (e.g. ISPF, DB2) was licensed and so are not available.

In VM how do you determine the amount of hardware MIPS, Disk, Etc... for let's say 1000 users? Is there any kind of formula to go by?

Building PC's capable of running many virtual machines can be expensive, but I would have thought fewer bigger machines would be better value for money. In any case when you consider the number of Network Cards and SAN HBA cards you will need those alone probably come close to small mainframe...

You could perhaps use a CMS exec to set the machine up and then IPL you non-cms OS Failing that, I remember from my misspent youth that we used to connect t o VM via TTY type devices. These strike me as potentially much easier to interface with than a 3270 session. Is that support, or support for some other line-mode type connection, still present in VM?

Re: z890 power: 3 phase vs 1 phase?
2 Live + ground is two phase. A three phase supplies doesn't need a ground, but usually one is provided to allow single phase equipment to be used. Power is generated by three phase alternators and these expect the load on each phase to be identical. So in most areas of buildings where high power is used (e.g. a large machine room or server centre) there will be outlets connected to each of the three phases and attempts made to balance the load across the phases. Certainly in the UK using the power in an unbalanced way may result in financial penalties. Typically three phase equipment performs the balancing internally so are desirable from the suppliers point of view. Even when we ran 4381's we still had a mix of three phase and single phase, but of course we are on 22volts. I don't think there is any three phase stuff left in our machine room any more.

Whilst as a consumer you should never connect Protective Ground and Neutral in the UK supply chain this is common. So whilst we have separate ground/earth and neutral wires in the house wiring and in the wall sockets etc. in many new supply systems we also have Protective Multiple Earthing which means that a single conductor in the supply line from substation to premises serves as both Earth and Neutral, and the internal earth and neutral are both connected to this on entry to the house. In these systems it is important not to separately connect the internal Earth or Ground to the real ground, and to ensure that all exposed metal work in the premises is earth bonded. This can cause Radio Hams like myself real problems as you can' put a separate earth on a radio transmitter.

The unfortuate status of the z/VM 5.3 evaluation version is that it's license from IBM states that it can only be installed on a z10 system. Installing it anywhere else would be a violation of the license terms. I am not a lawyer but the wording in the license is, to me, really odd. It starts by saying it will run on a Z10, but it doesn't say you can ONLY run it on a Z10. It actually says:- You are not authorized to install or use this Program on any machine that does not properly implement 64-bit z/Architecture I am not sure if that means if any one still has a licensed version of FLEX with 64 bit support they could run it. Yes, Hercules can run the evaluation version, so I've been told, but not legally. Actually most Hercules machines can't run the Eval as it needs 3Gb of memory, which most users can't provide... I'd like for IBM to offer some sort of hobby or non-commerical or educational license for z/VM, just so folks like yourself, newcomers to thjis operating system, could have some hands on experience at a very low cost point, but that's not happened yet. One thing you can do is follow this lista lot of advanced z/VM features and uses get discussed here by some really sharp VM-ers. Can I second that. Its a great place to hang out... Have a good one.

I was very happy that IBM offers now a evaluation version of z/VM 5.3 to everyone: http://www.vm.ibm.com/eval/ I really like hercules to play around with Linux for zSeries - but is it also allowed to run this z/VM evaluation version on hercules ? As i can remember, this was not allowed in the past. From my point of view this would be really good for z/VM because: - everybody (i.e. students) can get a deeper experience of z/VM - one can have full administration priviledges (employers/universities do typically not grant full administration priviledges) - one can have a portable mainframe (i.e. you play around with z/VM in the subway) - a better motivation to build up z/VM knowledge, because you are not dependent to your employers or university hardware - also universities which do not own a mainframe can teach mainframe knowledge - companies test their software on the mainframe - this emulator is available on linux and windows How can i install the z/VM eval version on hercules? Are there any redbooks/howtos available? (With the 3.0.6 release, hercules supports dvd-hmc support.)

Re: Secure FTP
Jack, Please don't run salt in the wounds of history, Many VM Hacks would love to provide such things, but for a number of reasons it is becoming harder to provide integration into the brave new world. Some if this is because to an extent IBM locked VM CMS in a closed closet source wise, and activley discoureged user mods. But its also due to availability of system access.

Re: INCREASE space on my A DISK

To make life inconvenient, CMS FORMAT cannot extend the formatted area. Smaller, yes; larger, no. So, you need TWO disks. You need a second disk to which you can copy the contents of your A-disk.

Re: Value added by z/VM versus VMWARE
-Original Message- From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of Barton Robinson Sent: 01 November 2008 23:34 To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Value added by z/VM versus VMWARE One thing that really bothers me about VMWARE. When I ask about performance to the people that measure, they tell me the VMWARE contract specifically states they are not allowed to talk about it's performance. A vendor that won't let people talk about performance must be very afraid details will be made public and don't really need to invest in improving it's performance. Since we can not provide facts to confuse management, it comes down to religion or companies providing their own facts. A professor from I think Stutgaart presented last year at the GSE/IBM meeting pretty convincingly that VMWARE was about 20 years behind z/VM in almost any fair technological aspect you wish to evaluate. And I think he was wrong - I don't see sharing of resources in VMWARE even what z/VM had 20 years ago. VMWARE is much more like LPAR, so any argument you can use for z/VM vs LPAR works as well. I believe VMWARE is great for desktops where users may want to run applications that only run on different versions of windows or Linux. Now there is a company in California that is even virtualizing the desktops, give end users a small appliance, keyboard and monitor, and the software runs on a virtualized PC, where all software runs on the central virtualized PC that then supports multiple users. They save a lot of money by only having one copy of MS Office to support multiple end users. (Does this sound like 3270 and mainframes to anyone else?) Firstly if you have multiple access software like Citrix where several users share the same copy of word, in general you need a license for each user. Its generally only one per concurrent user , but its still one per user. In fact the cost of licenses make Citrix some what expensive. You can buy a new IBM desktop PC, including a VISTA license (without monitor) for around a 1/3 more than a Citrix license. Given the cost of the citrix server the saving in capital is minimal. Of course you save in other costs, but when one of the Citrix boxes goes crank it hits many more users. Also Citrix does not cope well with demanding applications such AutoCad... In the VMWARE deployments we are looking at performance is is not a key factor. We have a large number of small servers that have a high waste factor. So typically these days each server will contain 2x72 gig drives (these are the smallest IBM will sell us) a 4 core CPU and 4 gigs of RAM. The server will be under used, but it will be kept serarate perhaps because the vendor product requires a specific version of JAVA, TOMCAT, Apache, MySQL or ORACLE, or for securty and audit. e.g. to limit access to a particular external supplier. Even if you can put four of these servers on a single VMWARE box then you have a significant reduction in waste, and VMWARE will allow you to migrate this workload without even letting the apps guys know what you are doing. Note zVM isn't currently an Option as we are firmly MS Windows, and as small VM/VSE site who has been neglected for years by IBM Mainframe folks turning this around would be hard. I guess if we invest seriusly in VMWARE it will by the IBM x Series supply chain that will be hit. Alan Ackerman wrote: Another question from the same architecture person. What is the value add ed by z/VM over VMWARE for a Linux workload? (That's my wording, not his.) As usual, I don't know anything about what VMWARE can or cannot do. I'm s ure it can run fewer guests than VM, but not how many. VM has shared DASD and DCSSes and NSSes , but most Linux people don't see the value of those things -- disks are cheap and come wi th the PC, memory is cheap, etc. VM has automation capabilities, but Linux has those too, and IBM sells all those Tivoli products to tie them together, report performance, provide high availabil ity, etc. I think the advantage on the mainframe is economy of scale. But how do yo u measure that? At present, you can save money on software and peripherals enough to cost -justify the mainframe. Reduced people costs are hard to quantify and scare the heck o ut of the midrange folks. But I wonder how long those software prices will last? Red Hat charges $1 8,000 per IFL for 7x24 support. (I found that on a web site, and I asked our Red Hat representat ive to make sure.) I couldn't find any prices on Novel SuSEs web site. We have other software with higher prices per engine for the mainframe. He specifically mentioned the ability to pick up a Linux guest running un der VMWARE and moving it to another box running VMWARE. So far VM cannot do that. Ideas on what value z/VM

If management is concerned about the 'safety' of their system that would be of a bigger concern to management if you ask me.

Re: VTAM R.I.P.
Whilst I never had the luxury of working in the labs I did do a lot of work on implementing code on GCS. When SP4 came out I was working for the University of Salford who at the time, in conjunction with IBM UK, produced a package of software and hardware that allowed VM to be connected to an X.25 network. The software consisted of service machine that was basically an X.25 switch, and which talked to X.25 via a Series/1 on the channel, and to other virtual machines via IUCV. When GCS and VTAM came out we modified the service machine to run in GCS. Initially it still talked to the Series/1 via the channel cards, but we then modified it to talk to X.25 via VTAM and NPSI. Appart from a few minor changes to WAITCB code and copying the LINEDIT code from CMS we made virtually no changes to the code to get it running on GCS. I am pretty sure we had access to the GCS source, (on fiche perhaps, my memory starts to fail at this point) and it looked very like the equivalent CMS code. What I really don't understand is why they didn't put more of the enhanced OS Support back into the original CMS. That would have been really usefull Dave P.S. still no VM at work.

These days if you want a Unix(TM) environment you can either use what I think are called OpenExtensions for z/VM or OpenVM for short which gives you access to a POSIX complaint subsystem within VM, I guess in a similar way to which you used to get OS/2 support in NT, or DOS support in VM. This is an EBCDIC environment. Alternatively you can IPL Linux in a zVM VM, which I guess is the way most folks are going. Note that whilst the base code is the same as Intel LINUX, the system needs to be built for the zArchitecture which evolved from 370/XA/ESA architectures resulting in zLinux. http://en.wikipedia.org/wiki/Linux_on_zSeries Seems to have a good overview which is mostly factual.

This won't run on modern hardware as its strictly 370 mode only and is pretty primitive in many ways.

I guess in some ways we have turned the world upside down. When IBM owned the PC platform it made products like the XT/370 and AT/370 that allowed you to run real CMS, not just a CMS shell on a PC That included REXX and XEDIT but not sure if PIPES would have run. Then we had the P/370 and P/390 cards that allowed you to run a whole OS on a PC. Now IBM is supressing Mainframe code on the PC and getting us to run LINUX images on VM and wants us to do our personal computing Linux on VM, and stops licensing for any 370 the PC platform. On the other hand what goes round comes round, and if you think of Linux as the main OS its licensing is similar to the orignal VM/370. I know there is no commercial value in it, so it won't happen, but wouldn't it be nice if IBM realeased a software emulation that worked like the original XT/370 that emulated both the Hardware and CP calls and so would allow CMS itself to be run native on Linux or Windows... .. oh and of course would license CMS for such an environment..

Hercules seesm to support 9345 devices, and will also read from real tapes on SCSI so it would be possible to do this under emulation, provided:- 1) You could find a SCSI drive that will read your tapes, or get some one to copy the tapes to AWS format files. 2) you could legally justify it under, say a disaster recovery clause in an existing license, or have IBM issue a limited license. 3) you have the minidisk layouts for the packs concerned we have previously noted VM DASD do not have VTOCS... If however you have a running system with different types of DASD connected, you can use DFSMS COPY to copy CMS formatted minidisks from one disk type to another (even from CKD to FBA). DFSMS comes free of charge with VM, but it is only installed when you explictely do it (DFSMS COPY is high speed, it used to be a lot faster than DDR). If this is your case, contact me again, I have some execs to help you during such a migration.

Perhaps with information such as: start cylinder, end cylinder, owning guest, read password, etc. CP owned volumes have an allocation map, this seems to me to be an extention of that concept. I don't know the answer, but in the historical context, putting directories on the DASD starts to get complex when running VM under VM using minidisks , not full-pack dasd. Historically you didn't have many DASD so you probably needed to do this for tested etc. How could the second level VM update the master directory on the front of the pack as all it can see is the extent defined as a minidisk?. And if it couldn't but it used second level mini disks, i.e. it subdivided its mini-disks into mini-mini disk you would not be able to (easily) migrate these back to the first level VM.

The reason they slow is beacuse of the way the I/O is designed in the SAN, that is down to a price not up to an commited I/O bandwidth and throughput.

Re: PSI story
... it is not running Itanium software, it is emulationg the zSeries arch. How does this make it slower? Another interesting argument. If the basic assumption is that the emulated zArch performance is proportional to the underlying Itanium performance, there's a lot of things that could be compelling here. Having not seen the CPU its hard to say what is going on, but the PSI blurb implied that they were using changed microcode and Just-In-Time tecniques to speed up emulation. Certainly Hercules seems to do an awful lot in this area, and the argument for Core Duos and Opterons seems to track Moore's Law closely. I can't really judge. I understand the mainframe at work (and I forget the model) is rated at about 70 mips. When emulating normal 370 mode, with Hercules, running VM/370R6, I get about 28 mips out out of a hyper-threaded 3ghz Pentium. I know its slower when emulating 64 bit, but from this it seems that Emulation could easily provide that level of performace on a 4-core box. (either 2 x 2 core or 1 x dual core).

Re: IBMLink 2000 Finding ESO levels
I've come to the conclusion that upper IBM management is trying to move all its customers to the PC/Microsoft model of software support: apply the latest service level, cross your fingers, and be quiet if all hell breaks loose. Any one who runs applying support like that deserves everything they get. We have a three level test process for applying patches to our workstations. No fixes are rolled out until they have been tested by key testers. After all, you took the risk by applying the service, and aren't you able to back it out? You can back out most PC fixes. Of course the ones you can't back out are the ones that break things. I'm not suggesting for one moment that this is the attitude of the VM or VSE labs (and it's probably not even the attitude of the OS/390 folks, but I never speak with them), but it's undoubtedly the attitude of people who populate the highest levels in IBM, who foist IBMLink 2000 on us as if it's an improvement, and who direct our concerns to someone in another country who has absolutely no experience doing the work we do and who, no matter how motivated he or she might be to provide excellent service, is absolutely incapable of understanding our problem. I had this problem with LexMark printer support. Fortunatly I had the luxery of telling the LexMark rep that unless he did better we would never buy a LexMark printer again. We had an engineer on site next day. Probably one of the things that's most irritating is the way advances like this are portrayed as if they're all in the service of progress, veritable gifts from the gods. It's a newspeak that at times can become almost frightening (one thinks of Healthy Forests and Clear Skies, but here I'm afraid I'm veering off the subject into verboten territory).

I don't believe that any copyrights have expired. There is plenty of software from this era which can't be used. These include many essential add-ins for VM/370 such as SEPP, BSEPP and even EDGAR. Note there may also be patents involved. These will probably have expired. VM/370 is actually a pretty limited OS compared to a modern VM. There is no REXX or even EXEC2. No pipes, no fullscreen support. Only the old editor to edit files. The disks are of couse the old 800 byte format, max of 64k files per disk and 64k recs per file.
