Re: How many shops... ?
While it will not answer your question directly, going to user groups and events will allow you to talk to customers running workloads in production, noting that most of these customers are not public references. Oracle workloads make up a large percentage of IFL usage (and no, I do not have any exact numbers to share). I can however recommend this user group meeting where some of our largest customers will be in attendance, speaking and networking at: http://www.oraclezsig.org/ For other events, I find this page to be very helpful: http://www.vm.ibm.com/events/ Hopefully this helps, Kurt Acker Cell: 607-348-8197 IBM Smarter Planet, Smarter Data Centers Virtualization and Enterprise System Management Technologies From: "Ambros, Thomas" <thomas_amb...@keybank.com> To: LINUX-390@VM.MARIST.EDU Date: 03/14/2016 11:44 AM Subject:How many shops... ?

Re: TCO comparison Intel vs EC12 IFLs
After talking to Phil about this some last night, the one thing that came to my mind was containable growth with scale! While working with customers, visiting datacenters and reviewing workloads for consolidation I've sadly yet to come across a case where mainframe growth is causing the need for more power then an areas grid can provide, or the floor space with people required to accomodate server sprawl. If you map out your datacenter, look at the z footprint, understand the services it's providing for your business and then really dig into and understand the true cost of everything else. Make sure you include the cost of moving, growing or building a new datacenter into that "cost of everything else" model you're creating, unless you really have unlimited reasources to work with. z Systems is of course not the answer for everything. Some x86 server sprawl can also be tamed by looking at Power. With our Linux everywhere and open directives, Power systems are starting to be used by customers that were born on x86: http://openpowerfoundation.org/ Hopefully this information is helpful, Kurt Acker Cell: 607-348-8197 IBM Smarter Planet, Smarter Data Centers Virtualization and Enterprise System Management Technologies -- 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 more information on Linux on System z, visit http://wiki.linuxvm.org/

Re: oracle licensing
As a general rule, from what I have seen helping out with lots of Oracle consolidations/working closely with our Oracle on z Alliance team (who is getting notice of this thread)... if Oracle can run on a IFL, you get charged for Oracle having access to that IFL. e.g. If your LPAR has access to a shared pool of IFL's, your going to be charged for all the IFL's in the pool. Depending on what else you are running, LPAR design options do of course exist that can help balance value to function. - Defining your options really involves a workshop/planning session.

Re: VDI?
I really like http://www.eyeos.com/ Many folks in this community know that I won an award as it was used to prove how effective a zVDI solution using none bitmap graphics could be (my final idea in this area was called Desktop on-Demand since DoD sounded right to me for this type of solution running on z). Fast forward approximately 10 years and we have now entered the era of killer apps. For applications like RDz, I think running it on a x86 server using eyeOS's virtualization engine (see video on bottom right of there web site) could make for a killer/very efficient way to support applications that work with z using BYOD type interface to the equation. - It removes the profile load part of traditional VDI solutions currently in mainstream use.

If you have SCO, you would most likely use that for provisioning over WAVE. - With the WAVE hooks in your golden Linux images, clones will be visible and accessible from WAVE. - Simplified z/VM GUI view of even your virtual networks helps ease system admin requirements and I like projects too. - Projects create a great way to host and present IaaS to lines of businesses. - Wave also presents performance dashboards. It is limited to z/VM with Linux. SCO really completes all the cloud requirements, and is not limited to z/VM with Linux. - Beyond the self service portal, it includes virtual machine life cycle management, patch management, charge back etc. Here's a SCO video that includes use of endpoint patch management for a deployed guest: https://www.youtube.com/watch?v=D18gEZcfgTU Hopefully this is helpful.

Re: zLinux Question
Greetings Mark, z/VM provides a great hosting environment for Linux on System z (or Linuz as I like to call it now that I have seen Lintel being used all over). Like any system however, it does require administration services. If you have a mainframe at your shop today, your zOS, zVSE or zTPF system admin should be able to help with a lot of the z/VM required parts/terminology, however you want someone that can manage z/VM in the loop. Having a good performance and transaction processing tool should of course help ease problem identification (provides you with the insight needed to act, however you have to have someone in place that understands what needs to be done, and can then get provide the required service). CSL WAVE can also be used to help simplify z/VM system administration requirements (green screens no longer really required). Truly a fantastic tool. Check out the video from its homepage: http://www.csl-int.com/ All the high level tools in the world are really great, however if you don't know how something really works, its really hard to fix it when its not working the way you would like it to be. A clear problem with our push towards self service and automation.

Re: VM Monitor
What I like about Performance Toolkit for z/VM (Perfkit) besides working on and supporting the product while at the lab in Endicott... is that's the tool the z/VM lab still uses helping to simplify collaboration with the lab when/if required. Understand that it is a hardware/system tool over something with a true software focus. Having Perfkit is a pre-req for Omegamon, a product offered from our software group. Omegamon is handy if you also have z/OS, have requirements to track transactions and want/desire dashboards. Worth noting along the lines of dashboards if you are also looking to simplify z/VM system administration, stay tuned for announcements around CSL WAVE as it pulls info from performance tools into nice dashboards as well. You can of course just get info from Linux directly with tools like TOP. Combined with z/VM commands enough information is obtainable to help keep your system healthy: http://www.vm.ibm.com/perf/tips/ No matter what product you decide works best for your org, go thru at least an internal solution assurance type review to understand the required resources/impact to your system as part of your decision.

LoZ Re: Z/LINUX for IBM

Personally I think we should start embracing LoZ as being a special, better version of Linux... not because Linux is not Linux on the platform, but because of what the platform and z/VM provides for Linux.

Re: LoZ proc use Vs Linux under other platforms
IBM still offers Scorpion and RACE studies. - The Scorpion study is a very extensive lab service offering - Both of them are now platform agnostic (no z in front of RACE). The RACE study now requires executive sponsorship and a commitment to move forward with a proof of concept (POC) if the numbers work out favorable for a System z solution. - The study is only as good as the information that is made available for it. - Processor types, utilization and or transaction rates, and then all the cost associated with your data center as a whole is a quick high level view of what is required. - When a data center is divided, or run by silos it can be very difficult to get everyone working together. - That is really required in order to collect really useful information for this type of study. A major message behind building a Smarter IT Infrastructures starts by managing your data center like a single, well oiled machine. - A lot of moving parts exist, and you want them all working together in order to insure smooth over all efficiency with consistent output exist. - Getting a great return on your investment also helps in todays economy.

FYI APAR HIPER flag change (cross posted)
Greetings, If you follow HIPER APAR's, please do not be alarmed. This note explains some changes that caused us to review all active APAR's, and change the HIPER flag when needed. System z, z/VM APAR HIPER and RSU process changes: IBM's current service guidelines requires all APARs that result in system outage be marked 'HIPER'. In z/VM's case, this also applies to APARs that correct virtual machine outages. This same APAR may or may not also be marked PERVASIVE. The previous guideline required any system or subsystem outage APAR to be marked 'PERVASIVE' in order to have been marked HIPER. As you can see this is a switch. To adhere to the current guideline, system outage APARs that were not marked HIPER have now been marked HIPER. zVM's RSU philosophy has been to put all HIPER APARs on the RSU. This has been changed. Now, APARs designated HIPER and PERVASIVE are automatically included on the RSU. All HIPER APARs are not necessarily PERVASIVE and as such may not be put on the RSU. The HIPER designation is for customer awareness that these problems exist, they cause a system or subsystem outage, and may or may not be on the RSU. Here are the newly designated HIPER APARs, currently in supported releases R510 and R520: VM56702 VM63454 VM63502 VM63540 VM63553 VM63558 VM63565 VM63567 VM63579 VM63590 VM63604 VM63619 VM63640 VM63650 VM63654 VM63655 VM63666 VM63667 VM63676 VM63694 VM63696 VM63717 VM63719 VM63720 VM63723 VM63769 VM63771 VM63772 VM63777 VM63785 VM63806 VM63807 VM63827 VM63828 VM63831 VM63832 VM63838 VM63840 VM63842 VM63843 VM63847 VM63858 VM63859 VM63860 VM63866 VM63871 VM63887 VM63888 VM63900 VM63903 VM63906 VM63907 VM63911 VM63913 VM63917 VM63924 VM63925 VM63930 VM63943 VM63954 VM63955 VM63956 VM63957 VM63962 VM63965 VM63970 VM63971 VM63973 VM63980 VM63986 VM63987 VM63988 VM63990 VM63991 VM63992 VM63994 VM63997 VM63998 VM64012 VM64013 VM64014 VM64015 VM64023 VM64029 VM64033 VM64036 VM64037 VM64042 VM64049 VM64052 VM64060 VM64075 VM64076 VM64083 VM64084 VM64099 VM64100 VM64103 VM64105 VM64115 VM64121 VM64125 VM64129 VM64141 VM64143 VM64144 VM64145 VM64154 VM64165 VM64173 VM64174 VM64183 Thanks and Best Regards, Kurt Acker -- For LINUX-390 subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: INFO LINUX-390 or visit http://www.marist.edu/htbin/wlvindex?LINUX-390

Q3 users get an enormous slice of the pie compared to those in a more interactive one and thus cause a more jerky ( or perhaps a less consistent ) feel by those trying to vie for resources.

Re: APAR VM63282
If I read the APAR correctly, it does not eliminate the need for guest to be dropped from the Q3 dispatch list, it just eliminates some network type activity from increasing the VMDIOACT counter field that may unnecessarily keep guest in a dispatch list. If the commands below only move you into other queues, its probably do to the guest still having some outstanding work, or the dispatcher believing you have some outstanding work that needs to complete. The big question is, are you experiencing a guest performance problem and looking at this as the reason why?

Re: Virtual machinnes freeze

Next time this occurs a: CP INDICATE QUEUES EXPANDED (ind q exp) command from a class E user could prove this. If the user/guest is in the eligible (E) list, that would indicate that the guest is waiting on resources. This would also explain why the guest can free itself.

For others information, the following was added to MAINT's profile exec allowing 1) the usage of VMADMIN SERVER commands (they all reside on MAINT's 193 disk) and 2) the ability to use TCP/IP functions such as PING from MAINT: ACCESS 193 P 'CP LINK TCPMAINT 592 592 RR' ACCESS 592 X Kurt Acker [EMAIL PROTECTED] VM/CP and VIF Level 2 Support Endicott NY Lionel Dyck Lionel.B.Dyck@kpTo: [EMAIL PROTECTED] .orgcc: Sent by: Linux onSubject: Re: Using SAF - a major doc gotcha 390 Port [EMAIL PROTECTED] IST.EDU 01/17/02 03:45 PM Please respond to Linux on 390 Port Note that after I re-ipl'd after finishing the VMADMCTL that I now get: LOGON AT 14:44:54 EST THURSDAY 01/17/02 z/VM V4.2.02001-11-15 15:52 vmadmin server Ready; T=0.01/0.01 14:44:57 Unknown CP/CMS command Lionel B.

The first thing I found (so far) is that the SAF doc is incomplete. After IPL'ing z/VM and logging into MAINT you *CAN*NOT* use the VMADMCTL command as it will not be found. You first have to enter VMFSETUP ZVM CP to access the appropriate disks and then VMADMCTL will start. Or am I missing something here? Lionel B.
