Re: Capacity Monitoring question
Where can I get a copy of GG22-9299. I have looked in IBM, but I can't seem to find it. From: The IBM z/VM Operating System [mailto:IBMVM@LISTSERV.UARK.EDU] On Behalf Of George Henke/NYLIC Sent: Thursday, March 03, 2011 10:43 AM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Capacity Monitoring question An operating system, be in z/VM or z/OS, will always try to drive the CPU 100%. This is goodness. So looking at max CPU will never tell you anything about CPU capacity, it is an almost meaningless metric which can be at best very deceptive, a common, innocent mistake and misconception. What is needed is the Saturation Data Point (SDP), which is calculated as the HIST average CPU peaks divided by the HISTaverage CPU average. The operative word here is HISTORICAL, 6 months at least. This will give you the peak-to- average ratio: 2:1, 3:2, or whatever. It depends on the nature of the workloads, their variability. It differs for every shop. Once you know the peak-to-average ratio all we need do at any given point in time is look at the average instead of the peak and that will tell us if we have reached the SDP and need more CPU. To illustrate: Let's say the CPU is pegged at 100% and averages 60%, though you ignore the average as unimportant. thinking you're configuring for the peak, not the average. Let's also say that your historical peak to average ratio is 2:1, though you do not know that or consider it important at the time. So the CIO orders a CPU upgrade, paying millions in TPV software charges for the upgrade. After the upgrade, the CIO looks at the CPU and sees it is maxing now at 60% and he is ecstatic because he thinks he has 40% CPU headroom and with about 5-10% annual CPU growth he has at least a 3 - 5 year life in the configuration. 6 months later, the batch window is expanding, batch is backing up, response time is degrading, CPU is maxing at 100% and the CIO wants to know what happened. With a 2:1 peak to average ratio, when the CPU maxes at: * 60%, it averages 30%. * 100% it averages 50%. * 120% it averages 60% So the headroom, initially, was not 40% (100%-60%) as the CIO thought, but only 20% (50%-30%) which got absorbed in 6 months But why so quickly? Why 20% in only 6 months? Remember before the upgrade the average CPU was 60%. That means the maximum CPU was really 120% not 100% and there was 20% latent demand. Machines do not report much more than 100% CPU. Another reason not to be mislead by max CPU. So between the 5 - 10 % normal CPU growth and the impact of the 20% latent demand, the config really had a life of only 6 months. True we should always configure for the peaks, not averages, but it is only the average that will ever tell us when we are out of CPU once we know the historical peak-to-average ratio. R.J.

Also we monitor guest CPU usage and metrics like the limit list. Linux memory is always at 100% so no sense in monitoring over there but we do monitor swap usage. Linux CPU gives bad numbers to start with (yes even on current kernel levels they are still wrong) so don't monitor CPU on the guests. Actually, 100% CPU is not a bad thing at all. Where most OS-ses become less responsive above 90% z/VM will still give you good response even at high numbers. We like to have it above 90%. Obviously you would need some capacity for new guests. So when you are running 100% CPU all the time there can be a case for an additional IFL. But also look at the guests, determine if they are running processes you don't need or that hurt overal performance. Watch your linux guests on responsetimes and batch runtimes. Set a good relative share and if that doesn't help you could consider adding IFL's. Keep VM paging below 50%, add paging DASD when needed. We have a VM that is overcommitted to 9:1. Our production Linux VM is at 2:1 with room to spare. Expect even high page IO rates, 1000's IO/sec don't have to be bad. Keep an eye on guests that are competing for storage. Especially loading users and E-lists can point to a resource problem. Try to fix it on the guest first (eliminate processes, reduce memory sizes etc). Make sure the guests don't stay in Q3. It will hurt other servers. So eliminate unused processes, don't use pings or other keep alive tooling. Be aware that most regular linux tooling keeps the guest active. Obviously when you are running batch the guest will stay in Q3 but then it's in there for a reason. Some of these issues are also covered

Re: Problems with MPROUTE going from z800 to z9BC computer
Sourcevipa is a TCP configuration parm. The book states: Note: For requests or connections originating at a z/VM TCP/IP stack, tolerance of device and adapter failures may be achieved by using the SOURCEVIPA feature. This capability causes virtual IP addresses to be used as the source IP addresses in all outbound datagrams except those associated with routing. This has burned me a couple of times because it chooses source ip address from the home list starting from the bottom up. It selects the first vipa address that it finds as the source ip for all communications.

So, when the guest tries to link the minidisk, there is no real volume for it to contact. It looks like the deeper problem is understanding how volumes work. Let me try to explain. What you refer to as the volume serial is really the volume label. It is written to cylinder 0 on the real volume when it is initialized, i.e. when you run CPFMTXA on it. If you are working with a basic install system image, then it was done for you already. These volume labels are what map a disk real address to a volume for CP to use. So, each volume label that CP is going to use, either as a CPOWNED volume or user volume, must be unique. CP only reads the label at IPL time, or when the volume is attached to the system. Most of the time, your volumes are attached at IPL time, based on what you have in your SYSTEM CONFIG file. However, volumes can be detached and attached to CP dynamically for different reasons. So, the problem of the guest being unable to link the full minidisk is because the volume labeled SYSPK is not attached to CP. From MAINT do: q dasd And you will see a list of disk volumes currently attached to CP. SYSPK won't be there, and it needs to be. Check your SYSTEM CONFIG file to see if it has been included in the user volume section. If you know the real address of the volume, you can manually attach it to the system by doing: attach (raddr) system However, this is only temporary. To make it permanent, you have to include it in your SYSTEM CONFIG. One thing I would like to point out is that SYSPK isn't a very good volume label (IMHO). You are likely to have a lot of volumes attached to this system some day. You need a way to keep them unique. So, give some thought to a better naming convention. You only have 6 characters to work with in a label. There is another problem described in your email as well. Using a full volume minidisk is dangerous. Since cylinder 0 contains the volume label (along with other important information), it isn't a good idea to include it in a minidisk allocation. By doing so, it allows the guest to overwrite the label without CP being aware of it. I had also done that with our z/OS guests for a long time, and my z/OS colleagues promised not to change the labels. Of course, over time, they did get changed. That resulted in a lot of problems whenever CP would be recycled. So now, I only give them full minidisks that do not include real cylinder 0, i.e. 1 through 3338. The guest doesn't know the difference. It allows them to use whatever labels they want without affecting the real label that CP uses. I do the same for our Linux guests as well. If z/OS needs a full volume image, i.e. all 3339 cylinders, then I put it on a large CP volume, such as a 3390-27. Again, the guest doesn't know the difference and it preserves the real labels for CP. Also, another piece of advice. If these volumes are going to be shared between z/OS guests, use the mode MWV, not just MW. Otherwise, the z/OS systems could run into problems. I hope this long explantion makes some sense to you. If not, please ask more questions. We are always happy to help new VMers. Martha McConaghy Marist College On Thu, 1 Apr 2010 10:36:13 +0900 TaeMin Baek said: Hi, I use z/VM v6.1 and z10 BC.

(This method is the preferred way of defining a full-pack minidisk because the number of cylinders does not need to be known when writing the MDISK statement.)

My approach would be indeed to run just one desktop per virtual machine, instead of what Matthew suggested with all desktops on a few Linux virtual machines. My preference would be the simplifier security issues and the ability to ensure that resources can be granted to the virtual desktop that is supposed to use them, and the ability to charge for consumed resources. Something to think about is whether the virtual machine needs to be there when the user is not. One of my pet projects was to speed up Linux boot process so that we could start the virtual machine when the first TCP/IP packet arrives (and get it done within the time that TCP/IP allows you). I even worked with a customer who considered to migrate unused virtual machines to tape and restore them when needed (and accept that it may keep the developer waiting for a few minutes). Clearly you want something to share the program code so that you can do software management in a central manner and not upgrade each virtual server separately. That requires you separate data from (centrally managed) code and server configuration. When you review the thread about stateless Linux on the list yesterday, it appears an attractive approach to have a small supply of luke warm Linux servers ready to get personalized when the user attempts to connect to the desktop. It would require their data and configuration to reside on a separate file server. I would be tempted to hibernate to disk rather than RAM (and expect z/VM paging to restore it) but either approach might work.

Re: Virtualized Desktop

And would they be able to use Ximian and Evolution to connect to an exchange server for email/calendar and those type of office functions? From: The IBM z/VM Operating System [mailto:ib...@listserv.uark.edu] On Behalf Of Matthew Donald Sent: Wednesday, May 13, 2009 2:07 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Virtualized Desktop Firstly, you need to know the expected environment before you can work out anything. Lets assume that you want to provide Firefox for browsing, Lotus Notes for email, Symphony for office and x3270 for mainframe access. All of these run under Linux and, in addition, Notes and Symphony are Eclipse-based which means JVM's. What I wouldn't do is give each user a separate Linux guest. I'd probably look at around 4 Linux guests. These guest would have all 1000 users logged onto them. One guest would provide the desktop. That is, every user would log onto a single guest using X-Windows and maybe Gnome (but I'd look at Enlightenment as it has a lower memory footprint). The desktop would have icons for Notes, Symphony etc. Clicking an icon would run a remote app on one of the other guests. Any user running Firefox or x3270 would run the app on this guest. A second guest would run Notes. Every time a user clicked the Notes icon, it would start it would start the Notes app on the second guest. The third and fourth guests would have Symphony workload spread between them. When a user clicked the Symphony icon, half would run the app on the third guest and half on the fourth guest. Essentially, the model is to have the basic desktop and the non-java apps on one guest and the java workload spread over the other three guests. I know a config along these lines would work, since the State of Florida did something like this in the late-90's. They were using four 8-way Intel P3 boxes running Linux with Netscape, Wordperfect and Quattro. I'm pretty sure they were supporting more than 1000 users. As to resources, I don't know of any benchmarks, so the following is based on my experience with z/VM +z/Linux + Websphere. My gut feel is that you could probably run this sort of workload with 4 IFL's and somewhere between 96G and 128G, depending on the number of simultaneous users. I may be over-estimating the CPU workload. Most of the memory requirement would be for JVM's. I'd allow somewhere between 128M and 256M per JVM. So long as the GC was running no more frequently than every 8 seconds or so and each GC run was freeing at least 30% of the heap on each run then the sizing would be adequate. Another problem you are likely to hit is in networking. The X-Windows protocol has outbound connections from the Linux guest to the terminal. I don't know about your environment, but many site use VPN's internally with each group being restricted to a single VPN sandbox. The problem is that many VPN clients (such as Aventail) only allow connections from the terminal to the server, and not the other way around.

Virtualized Desktop
Hello, all. I have a question. It seems that we are looking into a virtualized desktop environment (Single Image) on our distributed side. I kind of laugh at this because that's where we came from with VM and an OS running under VM (Green Screen) long ago and now it's making full circle. 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? I know in the distributed environment, it will probably take a lot of disk space, and as far as performance I don't think it would be as snappy as a real VM system. I used to work at a shop where we had 2500 users and a few with APL, that's right APL. Anyone that's been around knows what APL programmers did for VM. And in that shop response time was good even under MVS/CICS under VM. Anyway any comments, suggestions, criticisms are welcome.

Although, after making a simple calculation, I realized that it would take me about 80 hours to upload all the DVD files to the First-Level minidisk. Given that my 3270 emulation program (Extra) does not support file lists, I decided to abandon this idea. Since we do not have an FTP server attached to our VM systems I thought that a First-Level DVD Installation from the HMC would make more sense. My goal would be to install first-level and then test second-level. I am not certain as to whether or not this sounds reasonable and if there is some who would provide some guidance as to how this could be accomplished.

Lpar Vs VM
Hello all, I have a question. When we set up and lpar with an operating environment such as MVS, we get software charges for both lpars from IBM. Third party vendors don't seem to care if it's on the same machine (Most don't) since they charge for the full mip rate of the machine regardless of whether it's utilized or not. Long ago, about 30 years I had a VM shop and we ran multiple instances of OS/VS1, MVS, etc, but were only charged for on license of software product. Is this still the case? Is it better to use VM instead of LPAR? All comments appreciated.

Re: Lpar Vs VM
Thanks for the reply. Yours seems to be the best so far. I wanted to try and figure the cost of setting up multiple z/OS machines in a fairly quick manner. As I remember the old VM/BSEPP you could run as many operating systems as you wanted under VM and be charged for only 1 copy of the operating system. That doesn’t seem to be the case using LPAR’s . It seems that we get billed for running z/os on Lpar 1 and Lpar 2. They gather the amount from the SMF records that are produced. That’s why I was wondering if I would get billed for multiple z/os virtual machines under z/VM. From: The IBM z/VM Operating System [mailto:[EMAIL PROTECTED] On Behalf Of [EMAIL PROTECTED] Sent: Wednesday, August 27, 2008 12:49 PM To: IBMVM@LISTSERV.UARK.EDU Subject: Re: Lpar Vs VM I can’t speak to z/OS software charges, but for VSE, we pay for only one license for multiple instances running under z/VM. And we pay the VSE license for the total capacity of the machine. I don’t think you can say that VM is better than LPAR as a general statement. In some cases VM definitely is better, and in others, LPAR is the winner. Do you need to create new z/OS instances on short notice for a brief testing period? z/VM is a clear winner. Do you need every last CPU cycle for your production z/OS? LPAR is better here. Do you need to frequently shift resources around between your LPARs? z/VM might make your life easier. Is your hardware environment fairly static? Could be better to stay with LPARs. Are you thinking of running Linux on your mainframe? You will almost certainly want to run z/VM then. z/VM brings you unmatched flexibility, but at a cost of some CPU cycles and money. If you have large numbers of LPARs though, it can reduce the complexity of your configuration, and allow better sharing of your resources. Perhaps if you expand on what you hope to achieve, we can provide more targeted responses.
