Re: Oracle, zlinux, and virtualization
Mark, Is your picture from the Orlando presentation still valid when virtualization is factored in? The discrete system view factors in massive underutilization to be able to run on so few IFLs.

Re: RHEL 2.4 on Z9
Red Hat 7.1 and 7.2 were not commercial product offerings from Red Hat. Red Hat introduced its commercial offering with Red Hat Enterprise Linux 2.1, which was not offered on the s390. So I believe that there is confusion here between what is Red Hat Enterprise Linux and what is Linux. uname -r != cat /etc/redhat-release -Eric On Tue, Dec 2, 2008 at 3:41 PM, Mark Post [EMAIL PROTECTED] wrote: On 12/2/2008 at 10:50 AM, Eric Sammons [EMAIL PROTECTED] wrote: Going to try and help out David here, and Like David I may be wrong, but I don't see a RHEL 2.1 AS for any platform other than ia64 and i386.

Excellent recommendation from John, but ... On Thu, 13 Nov 2008, John McKown wrote: ... What I do in many cases is have cron run a script. That script then sources /etc/profile and ~/.bash_profile.

Better would be to instead source /etc/profile and ~/.profile and teach your users to do the same. Not only does Linux have alternatives to BASH but if you're in any mixed environment you possibly won't have BASH on the others (BSD, OpenVM, AIX, Solaris, HP, whatever).

Oracle support issues.
I should have been more clear. No support issues. Actually we had more support issues starting up with IBM than Oracle. -Original Message- From: Linux on 390 Port [mailto:[EMAIL PROTECTED] On Behalf Of Mark Post Sent: Wednesday, December 03, 2008 10:18 AM To: LINUX-390@VM.MARIST.EDU Subject: On 12/3/2008 at 10:25 AM, Little, Chris [EMAIL PROTECTED] wrote: It IS a seriously misinformed person.

Re: Contrainted System - What to do first and am I missing anything.
You're on the right track. I'd try storbuf 300 300 300 for immediate relief from the E3. But you are still overcommitted by a lot, more real storage (or smaller, fewer servers) is in order. With z/VM 5.4 you can add storage dynamically. Course, that assumes you've got some sitting in the z9 doing nothing at the moment...

STORBUF is the answer, the default is broken as designed.

Re: Contrainted System - What to do first and am I missing anything.
another question - did you set those 2 largish machines with QUICKDSP ON? If yes, why? In general I am not a huge fan of QUICKDSP, it bypasses some important scheduler decisions, somewhat defeating the concept of fair share scheduling. swplt01 and swplt05 David Kreuter From: Linux on 390 Port on behalf of Barton Robinson Sent: Wed 12/3/2008 4:33 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: Contrainted System - What to do first and am I missing anything.

Thu Dec 4 Live Virtual Class- A VSE Perspective of the IBM System z10 BC
For those on IBMVM, LINUX390, IBMMAIN who are interested in an hour of no-charge System z education via webcast. Note that today's (12/3/2008) LVC on Project Big Green is planned to be available for replay beginning Friday Dec 5. Here's another Live Virtual Class for Thursday December 4th at 11:00 AM ET. There is no charge to participate in this technical education session Date: Thursday, December 4, 2008 Time: 11:00 AM ET (US CANADA) Duration: 75 Minutes Title: Smart, Cool, Affordable - A VSE Perspective of the IBM System z10 Business Class Speaker: Mike Augustine, IBM - Offering Manager, System z Abstract: This webcast will provide an overview of the new z10 BC announced October 21, 2008 for z/VSE users. It will highlight why this server is the affordable choice that delivers more value than previous midrange servers and new technology that is the smart choice. IBM's new mainframe aims to assist midsize companies to jumpstart new application development efforts; consolidate IT servers; and give organizations a platform to build the mainframe as the foundation of their new enterprise data center. Registration: To register for this event, please use the following link: http://ibmstg.na3.acrobat.com/ztech1204e/event/registration.html This is the first z/VSE webcast using Adobe. You just need a web browser and the Adobe Flashy Player runtime software. You will only need to register one time for Adobe webcasts - where you will create a userid and password.

Re: Contrainted System - What to do first and am I missing anything.
Firstly, thanks everyone for you help. I did set storbuf as recommended. David: I try and keep quickdsp off as much as possible as well. Many fruitless arguments have ensued. It may be overkill to have it set 'ON' on a test LPAR but swplt01 is a firewall, swplt05 is a WAS portal. It is 'on' partly to give my unix admins a warm fuzzy feeling. I am beseeched at all times by Unix admins and Oracle DBAs who don't understand, and therefore, do not trust z/VM scheduling. It is an uphill battle at times but progress is being made, and as my knowledge comfort level increases, so does theirs. Thanks again, Tyler Koyl Viterra Inc.

If yes, why? In general I am not a huge fan of QUICKDSP, it bypasses some important scheduler decisions, somewhat defeating the concept of fair share scheduling. swplt01 and swplt05 David Kreuter From: Linux on 390 Port on behalf of Barton Robinson Sent: Wed 12/3/2008 4:33 PM To: LINUX-390@VM.MARIST.EDU Subject: Re: Contrainted System - What to do first and am I missing anything. STORBUF is the answer, the default is broken as designed. See first, http://velocitysoftware.com/faq.html;, and then http://velocitysoftware.com/present/CONFIG/; for configuration guidelines, that will help you avoid other such unavoidable issues.

This is our VM Test LPAR and the sum of the virtual storage of the linux guests is 14G so things are tight. What should be done first? 1. Further reduce guest storage. We have done this already but there may be a way to squeeze some more. 2. What about messing with SRM STORBUF etc? 3. Anything else besides ordering more storage? I am actually looking for something non-disruptive. Taking down a 6 LPAR z9 to add more memory to a test lpar does not go over well. We tend to tag this stuff on when production changes are made.

Red Hat introduced its commercial offering with Red Hat Enterprise Linux 2.1, I'm sure the people at Red Hat who were there at the time would be very surprised to hear that. Red Hat was generating revenue from Red Hat Linux long before Red Hat Advanced Server (not Enterprise Linux) 2.1 was released. Before RHEL there was Red Hat Linux Advanced Server 3.1. Basically, RHLAS was RHL 7.2 packaged as a commercial offering with support. Before that, RH was offering support for RHL (how else to make some money?), but RHAS as the beginning of the differentiation between free to obtain and not-free. Previously one could choose between free downloads and packaged options (including downloaded with support). RHLAS was subsequently renamed to RHEL. It's RHL 7.2 and 7.1 that I was recalling, for IBM mainframes. When RH released RHL 7.3, there was no corresponding upgrade of RHLAS which remained based off RHL 7.2. In the RHL series, 7.0 was the last RHL with a 2.2 kernel, RHL 7.1 the first with 2.4. -- Cheers John -- spambait [EMAIL PROTECTED] [EMAIL PROTECTED] -- Advice http://webfoot.com/advice/email.top.php http://www.catb.org/~esr/faqs/smart-questions.html http://support.microsoft.com/kb/555375 You cannot reply off-list:-) -- 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
Re: Contrainted System - What to do first and am I missing anything.
Tyler, As David indicated, QUICKDSP is a very big stick that has specific uses. Once you implement Barton's suggestion, you may want to handle prioritizing individual virtual machines with SET SHARE. Be careful there as well, the relative numbers are just that, relative to each other. Tyler Koyl wrote: Firstly, thanks everyone for you help. I did set storbuf as recommended.
