I realize several colleagues were aware (GT 6 mos ago) and I've substantially been able to stay clear of the 1.6 code, until today. New apps are driving this requirement. Can anyone provide additional insight? Who is working on it? My observations in this area were on JVM 1.5 that introduced a new optimizer that used polling to collect statistics for the profiler. According to my notes, JVM 1.5 SR4 introduced an unsupported and undocumented option to disarm it, and JVM 1.5 SR6 arranged to stop polling when there was no class active. So we should assume it's not present in your 1.6 JVM. But no guarantee that nothing else has been broken since... strace reveals active function call in futex() http://en.wikipedia.org/wiki/Futex This appears to be 100x worse then the old kernel timer pop event. There's also a kernel bug that rounds small delays to 0 which makes polling very painful. That would show by extremely high SIE intercepts (see ESACPUU) and high CP overhead. With the proper patches, the kernel will round the small delay up to 10 ms and reduce the CPU cost of polling (but it will still prevent the virtual machine dropping from queue when idle). If you're on a kernel 2.6.21 or later, you might want to pick up a copy of PowerTop which identifies the process that is polling (there's a s390x version at http://www.rvdheij.nl/linux/ ) You can match the PID against a java coredump and point fingers.

If you're on a kernel 2.6.21 or later, you might want to pick up a copy of PowerTop which identifies the process that is polling (there's a s390x version at http://www.rvdheij.nl/linux/ ) You can match the PID against a java coredump and point fingers. Do you have a sles10 version of that utility.

JAVA 1.6 BUG - Polling Loop
Some time ago it was asserted that there was an issue within the Java 1.6 code where an active timer loop was implemented in the JSDK for performance improvement. Thus causing an IDLE s390x system to appear to be using 99.X % CPU with HIGH CPUTIME for the java process. I realize several colleagues were aware (GT 6 mos ago) and I've substantially been able to stay clear of the 1.6 code, until today. New apps are driving this requirement. Can anyone provide additional insight? Who is working on it? strace reveals active function call in futex() http://en.wikipedia.org/wiki/Futex This appears to be 100x worse then the old kernel timer pop event.

Re: Advice for perf testing dasd
You may want to try one of the benchmark centers. They allow you to test across a spectrum of devices. I did a benchmark remotely at the IBM/Oracle Joint Solution Center with a system z and z storage. Oracle / ASM/ RAC / Devices / etc. Contact either IBM or Oracle or me offline for more details.

I'd really really appreciate any advice regarding how to structure and go about doing this testing. What I'm thinking about is testing the following: *) our dual, controller based mirrored DS4800s providing EKCD DASD *) Some FCP storage used as EKCD minidisk via z/VM (forget the proper term here) *) Direct guest attached FCP luns Our FCP luns would be coming from a set of HP XP controllers. Lacking other ideas, I plan to use a suitably intensive set of IOzone test runs as my benchmark - trying to test both large and small I/O operations. I'd plan to do all this testing on an up to date install of rhel 5.4 in a single IFL guest, tuned to minimal memory (just barely swapping) with a vdisk high priority swap and an EKCD low priority swap.

Re: A Question on Sizing z/VM Linux Guests
I run my Oracle guests GT 90% mem and use Velocity to watch the WSS size and +- SGA for good performance on s390x. This approach is opposite of what (as you may of heard) you may do to improve performance on I686-RHEL. NONE of the individual guest DBs are over 4.0G MEM. Here is a recent tuning change which droped IO in the guest over 100% for a 4G guest.

And yes failover is available for configuration.
Never tried it, but it looks like s390x is an option.

I did hit an error I could not get around. When I the ssh -X r...@ip-address to start the install the first part that was text based worked fine. When the X Window tried to open on my desktop an error was returned stating a Bad Value was passed. I have dual screens with a Nvidia card on the host so I thought maybe that was confusing X somehow. I placed it back to the 1 monitor but same error. I ended up invoking ssh without the -X to finish the text installer. That did work and 5.4 is install and will boot under Hercules. Again, same question. Does this seem like a reasonable install time? Next Step: I have booted zVM 5.3 but have not really done anything with it. My next goal is to boot that and setup at least 2 zLinux installations. Likely I will use the disk files I have already created. It has been almost 20 years since I have done any VM/CMS commands.

Re: Linux and z/VM Wiki
Nice work Mark! Will spend some time there. Gerard -Original Message- From: Linux on 390 Port [mailto:linux-...@vm.marist.edu] On Behalf Of Mark Post Sent: Wednesday, September 16, 2009 2:21 PM To: LINUX-390@VM.MARIST.EDU Subject: Linux and z/VM Wiki Cross-posted to Linux-390, IBMVM, and IBM-Main The idea of having a Wiki (http://dictionary.reference.com/browse/wiki) for mainframe Linux and z/VM has been floating around for some time. It was thought that having a Wiki with a fair amount of content already in it would help it reach a critical mass of usability far sooner than might otherwise happen. A fair amount of behind-the-scenes work has been done over the last couple of years to make that happen, without much success. So, I've decided to take a different approach. With the assistance of Marist College (and Velocity Software who owns the domain name), I've put up a Wiki at http://wiki.linuxvm.org/wiki/ for people to contribute content. We'll see how things go from here to determine if it's worth keeping or not. There are a few rules, for lack of a better term, that will apply to the Wiki, none of them particularly onerous: 1. Although technically not required, we would prefer that anyone contributing to the wiki create an account before doing so. 2. Keep things civil and professional, both in the articles themselves, as well as the discussion pages for them. 3. Keep things accurate. We expect vendor-specific information to be entered here (although we'd prefer to not have pricing details). But, any exaggerated claims, vapor ware announcements and the like are subject to summary deletion. 4. Try to keep bias to a minimum. Everyone has their favorite distribution or way of doing things. Try not to let others people's preferences in those areas be cause for any Holy Wars [TM]. 5. If you don't own the copyright to something, don't add it to the wiki. 6. Use common sense in general. I hope that people find this useful, and are willing to contribute as they are able. With any luck, it will become a valuable resource for everyone that might become involved in running Linux on System z.

He plans to migrate the core workloads to Linux (Red Hat) on System z. The application performance had to be measured between System z9 versus System z10. The scenario is a data import from a DS8000 storage server into an Oracle 10g R2 database running Red Hat under z/VM 5.3 on a System z - The size of the environment in terms of CPUs, memory, and disks, was defined according to customer needs.

As for academic ventures, WSU's Computer Science department became a program under the College of Engineering quite sometime ago. I'm also suffering under the myth that no one is teaching mainframe anymore. (As an aside, I sorta resent perception. In my day :) you didn't get taught or trained much, we just dam well did the work :) In the few moments I can spare from keeping our z/OS system going and maintained (I'm still running 1.7 in the important LPARs), I need to show that Oracle (database and applications(ERP will likely be Banner or Peoplesoft) runs well on zLinux and that zLinux under zVM is cost effective in a major way over HP or Sun or other Intell farms. By the way, I never intended to imply that we would never buy zVM or additional zHardware and that I wanted to do this on the sly in the long run. I just have some (longish) short term delay. We had to cut out the Watson newsletter and are seriously looking at any way to save some pennies :( We're also very short handed do to the budget and other problems. P.S. It's been awhile Dave, I've often wondered if you were the same Dave Boyes that spent some time here. The 3090's been gone a long time now. Given WSU's historical relationship with IBM, I would suspect that if you asked IBM for a loaner copy of z/VM, one would appear for a long period of time. I think that while you *could* do VM-LPAR, it would probably be less hassle and more productive to try to negotiate a long-term loan. -- db -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390 -- For LINUX-390 subscribe / signoff / archive access instructions, send email to lists...@vm.marist.edu with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

Re: Server sizing from AIX to z/Linux - Rules of thumb?
When I did the port of a Java AJP (Apache Jserv Protocol) from AIX to system Z Linux I used jmeter to conduct simulations for the sizing's. We went from AJP http://en.wikipedia.org/wiki/Apache_JServ_Protocol To MOD_JK on system z Linux. http://tomcat.apache.org/tomcat-3.3-doc/mod_jk-howto.html Case and point, being when you conduct research for porting you always bring your source technology stack forward to relatively recent levels during the migration. It should never (IMHO) be a one for one level migration. We have also ported *many* other workloads from XXX to LoZ - Some approaches: I would 1) Port the stacks with current OS, WEB,APP,DB servers. 2) Study the zPlatform specific well documented OS settings * z/VM subsystems (Processor, storage, I/O, paging) * z/VM guest resource * Linux on System z - disks, storage, processor * Networked servers (Linux, Unix, Windows) * Linux Applications 3) Build a driver tool that allows you to meet the desired #Users and concurrency. 4) Execute and acquire. During the port you may wish to over configure (CPU_MEM) and then scale back as you iterate the tests. http://jakarta.apache.org/jmeter/ http://wiki.apache.org/jakarta-jmeter/JMeterLinks Gerard C.

Wondering if anyone has some rules-of-thumb for sizing a z/Linux virtual server for AIX-based workloads, specifically CPU memory. All I am looking for are rough guidelines that can be used as a starting point to estimate resources for moving a workload from a mid-tier platform (AIX) to a mainframe virtual Linux server. For example, we have AIX Server based applications that use a 3-tier architecture that consists of: 1) Web Server - 2 CPU, 2 GB RAM 2) App Server - 4 CPU, 8 GB RAM 3) DB Server - 4 CPU's, 16 GB RAM, 100 GB Storage I realize that it ultimately depends on just how busy a server is in order to determine resource requirements with any degree of accuracy, and explained as much to those that asked me about this, and being short of any empirical data at this point, was hoping that others may have derived some basic guidelines based on their experience. We're looking at potentially moving hundreds of AIX servers onto mainframe-based Linux servers, so trying to get a handle on just what that will mean in terms of resources. I figure the disk-based requirements would be pretty much Gig-for-Gig, but not sure how to factor AIX CPU's to z10 IFL's and the scaling factors going from AIX RAM to central storage. I humbly ask for any help towards getting a better handle on this, which would be greatly appreciated.

Comments? A lot of us have seen that happen frequently, especially if the tuning is being done by someone with no mainframe experience, and hence only a midrange mindset. That usually goes something like this... Hmm. Things are running a little slow. We should add more memory to the system. Rats, that didn't help. Let's add some more processors and see what that does. Gee, that didn't help either. These mainframes are a piece of junk. The next most common failing is that they will run artificial benchmarks and compare one Intel/AMD system to one guest running on z/VM. What they should be doing is running real workload on 10 or 20 Intel/AMD systems and comparing that to 10 or 20 guests on z/VM. Even if they do that, they can't just look at raw performance, they have to take that and factor in the TCO of everything that goes into making those 10 or 20 systems or guests provide that amount of work. It's usually hard, so most people don't do it. So they do the one-to-one comparison and declare victory when the inevitable happens. Yes, WebSphere startup can be rather slow, since WebSphere is a resource hog of the first order. But, if you're doing things right, you shouldn't have to start it up very often, and if you do, there's another instance running that is providing service while that goes on. Also, having a z10 makes a big difference as well, since the processor cycle time is considerably faster than a z9. But, the fact of the matter is, some of our customers, such as Nationwide Insurance, run _hundreds_ of Linux guests running WAS on them, on one box, and they're happy with what they see. Particularly for their mission critical work, including their corporate web site. One of the big reasons for that is they understand z/VM and how to get the most out of it. That means doing such things as making guests as small as possible, giving them as few virtual CPUs as possible, having Linux take advantage of as many z/VM facilities as possible, and so on. Trying to get by without some real z/VM experience is pretty much a way to guarantee failure. Second, they have a real z/VM and Linux performance monitor that they can use to understand what is really happening and make adjustments. Other customers have done things such as apply application profiling tools to find areas of particularly poor quality application code and fix them. In several cases, those applications experienced one or two orders of magnitude improvement in performance, with only very small changes in the application. Anyone who's studied performance management will tell you that you get your biggest improvements just that way, since it's usually not the hardware or operating system that is so far out whack that things run horribly. (They can be, but usually aren't in a mainframe shop.) I could go on, but I won't. There are workloads that aren't appropriate for the mainframe, even with z10 hardware. Oracle, DB2, SAP and WAS don't usually fall into that group. Mark Post

Re: Oracle DB's and Why??
We are running Oracle 10.2.0.3 on Linux System Z. These were new workloads for Business Intelligence, and Document Imaging. Rationale for choosing system Z was; Platform superiority over all others! Then; Cost avoidance - Performance - Scalability - Security - Native support for backup/restore/DR - Ability to diagnose end to end - Grid Integration (Agents z, Server Linux Intel) - Integration with Hipersockets for ZOS interfaces - Simplified administration - Ability to virtualize and clone new Oracle instances - Gerard C.

It helps to install a SLES10SP1 system from scratch before you try to upgrade. Our shop runs SAP. SAP requires changes to files like /etc/services. Some of those files get overlaid. One of the tasks before starting the upgrade is to identify what all the upgrade is going to overlay that you have changed. We started out with the redbook, so we copy our SLES10 SP1 CDs to our NFS server. We updated our parmfile to point to the NFS server. Then we execute the REXX to boot off of the SLES10 CDs using the parmfile. We then pick the language, then configure the disk drives, then when it ask you what installation mode to use, pick update. The upgrade overlays certain files like /etc/services, so we have to fixup the /etc/services file. We are also an SAP shop, so we have to fix things so that SAP will start up after the upgrade. Our document with our procedures is about 28 pages (with lots of pictures). One thing I did check was the release notes for SLES10. Supported Update Paths Updates from SLES 9 to SLES 10 are supported starting from one of the following bases: * SLES 9 GA * SLES 9 SP3 * SLES 9 SP3 plus the latest patches from the maintenance Web SLES9 SP2 is not listed as supported.

Re: SLES 10 SYSTEM UPGRADE and Starter SYSTEM
Hmm. Where do I start. Sorry this has been frustrating and unexpected. We began with a straight upgrade path with a guest pointed at a SLES10 NFS installation source. After lots of attempts we installed the starter system (which is nice) It allows you to boot the existing guest (sles9 spX) you would like to upgrade then execute a startup script which leads to having a SLES10 starter system with the old SLES9 DISK/RPMs, etc. Then you are able to (or alleged to be able to ) simply execute YAST/System update and the update would continue with a proposal and all that. We have been at it for weeks. Bottom line is the disks/mount points are NOT recognized. I'm almost ready to bag it up and do straight installs but no_can_do with the number of guests and amount of customization of each.

Re: Running Oracle on GT 2 IFLs
What I should have indicated was there no NO plans to exceed the number of physical IFLs installed. The number specified on the MACHINE statement would always be EQ or LT the number of physical IFLs. My question was more on the benefits of running with MORE available to zVM with FEWER specified in the quest directory entry.

We are discussing sizing's and I've heard that it may be advisable to remove MACHINE statements in the zVM guest directory for Oracle. The general rule is to not have more virtual CPUs defined to guest than that guest can saturate at peak loads. So, if you see your CPU pegging at 100% or close to it, add another CPU. Oracle can and will make use of them. Just don't define extra CPUs just in case *unless* you use the maxcpus kernel parameter to only activate (at boot time) the ones you know will get used. Then, if needed, you can activate more than that without taking the system down.
