On April 10th, 2018 <a href="https://www.redhat.com/en/about/press-releases/red-hat-strengthens-hybrid-clouds-backbone-latest-version-red-hat-enterprise-linux" target="_blank">Red Hat announced</a> the next regular update to their flag ship operating system. <br />
<br />
The
kernel level for 7.5 is kernel-3.10.0-862.el7. The kernel level for 7.5-alt is kernel-4.14.0-49.el7a.<br />
And this is actually the largest change. There is an alternate DVD with very interesting stuff. As Red hat wrote in their announcement: "This release also brings support for single-host KVM virtualization and
Open Container Initiative (OCI)-formated runtime environment and base
image to IBM z Systems."<br />
<br />
On top the classic kernel got a lot of bug fixes and security & crypto enhancements<br />

A frequently question in the past was: which physical CPUs is my LPAR using right now? Since z14 the Hardware Management Console provides this for authorized users. The task is called "View partition Resource Assignments".<br />
The Washington System Center has provided a short whitepaper "<a href="https://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP102754" target="_blank">IBM Z: Accessing the LPAR Resource Assignment Task</a>" with the details. <br />

On March 21, 2017 Red Hat has <a href="https://www.redhat.com/en/about/press-releases/red-hat-launches-latest-version-red-hat-enterprise-linux-6-pairing-production-stability-it-modernization" target="_blank">announced</a> the availability of RHEL 6.9. This marks the transition into what in Red Hat's <a href="https://access.redhat.com/support/policy/updates/errata" target="_blank">product life cyle</a> is called production phase 3 (starting May 10th 2017). This means that only critical security updates and urgent functional fixes will be delivered.The kernel level is now kernel-2.6.32-696.el6, for the main bug fixes see the <a href="https://rhn.redhat.com/errata/RHSA-2017-0817.html" target="_blank">kernel update description</a>.<br />
<br />
As usual there are the <a href="https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/6.9_Release_Notes/index.html" target="_blank">release notes</a> and the <a href="https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/6/html-single/6.9_Technical_Notes/index.html" target="_blank">technical notes</a> in two separate documents. The complete documentation can be reached from the <a href="https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/">Red Hat documentation page</a> (you need to select "6" on the left bar).<br />
<br />
The IBM documentation for RHEL 6.4 on <a href="http://www.ibm.com/developerworks/linux/linux390/documentation_red_hat.html#rhel64" target="_blank">developerworks</a> still applies for this release.<br />
<br />
This is mainly a bug and security fix release.

Many Linux clients are running under <a href="http://www.vm.ibm.com/" target="_blank">z/VM</a> as the hypervisor. This year three of the older versions are <a href="https://www-01.ibm.com/software/support/lifecycleapp/PLCDetail.wss?q45=V181274O23343W58~U247558U28969I52~D799503N87101H83" target="_blank">reaching end of service</a>: <a href="https://www-01.ibm.com/common/ssi/cgi-bin/ssialias?subtype=ca&infotype=an&appname=iSource&supplier=897&letternum=ENUS914-150" target="_blank">z/VM 5.4</a> (12/2017), <a href="https://www-01.ibm.com/common/ssi/cgi-bin/ssialias?subtype=ca&infotype=an&appname=iSource&supplier=897&letternum=ENUS914-012" target="_blank">z/VM 6.2</a> (06/2017) and <a href="https://www-01.ibm.com/common/ssi/cgi-bin/ssialias?subtype=ca&infotype=an&appname=iSource&supplier=897&letternum=ENUS213-297" target="_blank">z/VM 6.3</a> (12/2017). As I know that many of you are still running one of those versions, <b>it's time to move to <a href="http://www.vm.ibm.com/zvm640/" target="_blank">z/VM 6.4</a></b> and/or talk to IBM with respect to extended service. <br />
On the <a href="http://www.marist.edu/htbin/wlvindex?LINUX-390" target="_blank">Linux-390</a> mailing list <a href="mailto:bitnerb@us.ibm.com" target="_blank">Bill Bitner</a> thankfully <a href="http://www2.marist.edu/htbin/wlvtype?LINUX-VM.94086" target="_blank">offered his help</a> if you've got any migration questions. So take him up on that offer! <br />
<br />
Also take a look at Bill's presentation "<a href="http://www.vm.ibm.com/devpages/bitner/presentations/vm64prep.pdf" target="_blank">z/VM 6.4: Preparation & Use</a>". It's quite useful to see what changed for the better.<br />

Red Hat <a href="https://rhn.redhat.com/errata/RHSA-2017-0862.html" target="_blank">announced the end of service for RHEL 5</a>. They will offer another three and a half years of security patches and critical fixes if a customer has bought the <a href="https://access.redhat.com/solutions/690063" target="_blank">Extended Lifecycle Support (ELS)</a>.<br />
<br />
This enterprise distribution has been in the market now for more than ten years. Now it's time to move on. Best of course would be the RHEL 7 stream, which right now is at RHEL 7.3. Every day you stay on the old release without security updates is increasing the risk of being hacked! <br />

From my perspective this spring <a href="http://events.share.org/Winter2017/Public/Enter.aspx" target="_blank">SHARE in San Jose</a> was a "normal" SHARE. It was small enough to run into people to talk but large enough to have good technical content. The "hype" themes this time from a Linux perspective have been Blockchain - more precise <a href="https://www.hyperledger.org/" target="_blank">Hyperledger</a> - and Docker. The exhibition was also good - from a Linux perspective we had all three distributors partners there.<br />
<br />
Here is a completely biased list of presentations that you may want to look at. I've only included the ones with handouts. Several good presentations did not have handouts. <br />
<br />
<b>Linux / VM / KVM</b><br />
<ul>
<li>KVM on IBM z Systems Performance (<a href="http://share.confex.com/data/handout/share/128/Session_20792_handout_10097_0.pdf" target="_blank">part 1</a> / <a href="http://share.confex.com/data/handout/share/128/Session_20792_handout_10157_0.pdf" target="_blank">part 2</a>) - the first KVM on z performance presentation</li>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20178_handout_10099_0.pdf" target="_blank">Linux Distribution Performance Update</a> - what's been new performance wise in the distributions in the last year</li>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20179_handout_10098_0.pdf" target="_blank">Linux Performance Tools in 60 Minutes</a> - my tools overview</li>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20170_handout_10126_0.pdf" target="_blank">Putting SMT to Work on z/VM</a> - eventually we need SMT nearly everywhere to achieve best throughput</li>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20183_handout_9922_0.pdf" target="_blank">Whats New in Linux on z Systems?</a> - Martin's excellent overview on what's coming from upstream</li>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20154_handout_10125_0.pdf" target="_blank">z/VM Platform Update</a> - Bill's overview presentation on what's new in z/VM</li>
</ul>
<b>Blockchain</b><br />
<ul>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20510_handout_10246_0.pdf" target="_blank">Getting Started with Blockchain</a> - get an overview over Hyperledger / Blockchain</li>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20740_handout_10132_0.pdf" target="_blank">Blockchain Architecture</a> - the given presentation was for me the best I heard at SHARE. The handouts are good but nothing compared hearing this one live. You need a good general understanding of Hyperledger / Blockchain to follow this </li>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20534_handout_10275_0.pdf" target="_blank">Blockchain - How to be Secure, Compliant and "Regulation-Ready" </a><br />Security is so important for Blockchain - here are some more details behind it</li>
</ul>
<b>Docker</b><br />
<ul>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20172_handout_10310_0.pdf" target="_blank">Building and Running Your Docker Containers on z Systems </a></li>
<li><a href="http://share.confex.com/data/handout/share/128/Session_20194_handout_9923_0.pdf" target="_blank">Docker and z Systems</a> - Overview presentation</li>
<li><a href="javascript:DownloadHandout('1955','Docker%20http://share.confex.com/data/handout/share/128/Session_20191_handout_10376_0.pdf" target="_blank">Docker Demystified for Mainframers</a> </li>
</ul>
Besides my three presentations I'm glad that I could help a few people solve there performance problems. Thanks for all the discussions I had there with clients and IBMers and friends from around the US!

<br />
On November 8th 2016 eleven months after the last service pack <a href="https://www.suse.com/de-de/newsroom/post/2016/new-suse-linux-enterprise-12-service-pack-2-speeds-innovation-with-reliability/"> SUSE has released </a>the latest updated to their flag ship server distribution. SUSE also has a <a href="https://www.suse.com/communities/blog/suse-linux-enterprise-12-service-pack-2-product-launch/">blog post</a> with some more details. <br />
<br />
The
kernel level for 12.2 is kernel-4.4.21-69.1. This is a jump in the kernel version from the old 3.12 based kernel. It's the same major kernel level that's being used by Canonical for <a href="https://linuxmain.blogspot.de/2016/09/ubuntu-16041-and-kernel-support-map.html">Ubuntu 16.04</a>. And with that kernel a lot of new functionality is delivered. SUSE and IBM worked hard to ensure that for applications it behaves the same. <br />
<br />
What's new (details see documentation and release notes):<br />
<ul>
<li>The <a href="https://www.suse.com/releasenotes/s390x/SUSE-SLES/12-SP2/#Intro.New">release notes</a> states that SUSE now fully supports MariaDB. They have version 10.0.27 inlcuded</li>

On November 3rd 2016 <a href="https://www.redhat.com/en/about/press-releases/red-hat-powers-network-storage-performance-latest-version-red-hat-enterprise-linux-7" target="_blank">Red Hat released</a> the next regular update to their flag ship operating system. <br />
<br />
The
kernel level for 7.3 is kernel-3.10.0-514.el7. <br />
<br />
Here is my usual summary of links to more information:<br />

It's highly recommended that you upgrade to the latest fixpacks though. Read more in the <a href="http://www.ibm.com/support/techdocs/atsmastr.nsf/5cb5ed706d254a8186256c71006d2e0a/aeb426a4224db26e852580480055bee6/$FILE/RH7%20on%20zLinux%20Oracle%20DB%2011gR2%20_OCT_7%202016%20_%20Martin_Reder_Adamovich.pdf" target="_blank">IBM Flash</a> or go directly to <a href="https://support.oracle.com/" target="_blank">Oracle support</a> and read the Oracle Note (requires Oracle login):<br />
<ul>
<li>1967531.1: "Requirements for Installing Oracle 11.2.0.4 RDBMS on RH7 on IBM: Linux on System z (s390x)" - which has detailed installation instructions, which are a must read before trying to install. </li>
</ul>
As usual with Oracle certifications RHEL 7.1 is the minimal level required. <br />

<a href="https://ibmdocbuddy.mybluemix.net/" target="_blank">IBM Doc Buddy</a> is a mobile app that allows for retrieving explanation on IBM z error message codes. Now you can also get Linux and z/VM messages offline explained with this app.<br />
You can get the application from <a href="https://geo.itunes.apple.com/us/app/ibm-doc-buddy/id1121244571?mt=8" target="_blank">Apples Appstore</a> or from <a href="https://play.google.com/store/apps/details?id=com.ibm.systems.supportassistant&utm_source=global_co&utm_medium=prtnr&utm_content=Mar2515&utm_campaign=PartBadge&pcampaignid=MKT-Other-global-all-co-prtnr-py-PartBadge-Mar2515-1" target="_blank">Google Play</a>, depending on the mobile device you use. <br />
<br />
The information is the same as in the books (note that Ubuntu and Red Hat don't have included the message numbers yet):<br />

One of them is <a href="http://www-03.ibm.com/software/products/en/filecontmana/?S_TACT=M16106YW" target="_blank">IBM FileNet</a>. Storing a lot of data and finding content is something that z Systems does really well. So after the <a href="https://linuxmain.blogspot.de/2013/09/new-whitepaper-covering-ibm-filenet-p8.html" target="_blank">first whitepaper</a> concentrating on FileNet there is a new paper that adds <a href="http://www.ibm.com/software/products/en/content-navigator" target="_blank">IBM Content Navigator</a> and <a href="http://www.ibm.com/systems/storage/spectrum/scale/" target="_blank">IBM Spectrum Scale</a> (formerly known as GPFS) to the mix.<br />
<br />
This new paper is split into two parts:<br />
<ul>
<li>The first part with the title "IBM Enterprise Content Management for Linux on z Systems Scale-Out Case Study (Part 1): Single ECM Node with XFS and IBM Spectrum Scale 4.2" is available on <a href="https://www.ibm.com/common/ssi/cgi-bin/ssialias?htmlfid=ZSW03340USEN&" target="_blank">Partnerworld</a> (direct pdf download).</li>
<li>I'll update this post as soon as the second part is available</li>

The operating system was a <a href="https://linuxmain.blogspot.com/2015/12/suse-linux-enterprise-12-service-pack-1.html" target="_blank">SLES 12 SP1</a> and this was run on a <a href="https://linuxmain.blogspot.com/2015/03/z13.html" target="_blank">z13</a> LPAR with 6 cores and SMT enabled. <br />

As you can see you there is a solid 33% percent improvement going from the first Java 7 version to the latest Java 8 SR3 FP10 version. <br />
<br />
<b>So the first recommendation when you are having Java performance problems with Linux on System z is to try a more advanced Java version.</b><br />

There is a new <a href="https://www-03.ibm.com/support/techdocs/atsmastr.nsf/WebIndex/WP102653" target="_blank">whitepaper on TechDocs,</a> that describes the HowTo setup the Linux distributions RHEL 7.2 and SLES 12 SP1, so that OpenSSH (and all workloads using this) really benefit from the hardware encryption delivered with System z.<br />
<br />
One of their key outcomes is that you either need to<i><b> </b>specify</i> the accelerated ciphers <i>explicitly or</i> <i>put</i> them<i> at the top of the search order</i> of OpenSSH.<br />
<br />
Abstract: "This article summarizes our experiences with the configuration and usage
of OpenSSH using hardware cryptographic support of IBM z Systems. We
report our findings in the areas of performance and throughput
improvement. Our positive experience indicates that you should make use
of this capability when using OpenSSH."

End of July Canonical <a href="http://fridge.ubuntu.com/2016/07/21/ubuntu-16-04-1-lts-released/" target="_blank">released the fix update</a> for their first mainframe release. No new features but a lot of fixes, for Linux on z many installation fixes. If you are using (or planning to use) Ubuntu 16.04 LTS it's time to think about the life cycle. Here is the <a href="https://wiki.ubuntu.com/Kernel/Support#A16.04.x_Ubuntu_Kernel_Support" target="_blank">support map</a> from Ubuntu Wiki:<br />

My recommendation is the following:<br />
<ul>
<li>For<b> production use</b> stay with 16.04.1 stream for the life of the product. Plan for a check point in spring 2018 and check if you need the additional hardware enablement delivered with the 16.04.5 kernel. </li>
<li>For <b>development use</b> you probably want the latest kernel anyhow. There 16.04.2-16.04.4 are valid choices. However I'd rather upgrade everything and go with the 16.10, 17.04, 17.10 versions. This will give you the latest versions of all the open source packages as well. </li>
</ul>

I expect this to change over time, so please revisit for updates.<br />
<br />
For the virtualization layers I use the label "(guest)" for enablement of guest exploitation. So you need at least the given version of the Hipervisor to exploit a certain function in the guest. Of course you also need the respective guest support.<br />
<br />
All version levels in the table are minimum levels. <br />

The new <a href="https://lists.fedoraproject.org/archives/list/announce@lists.fedoraproject.org/thread/E465E4KYQB2ETREQLDOL5KMAZEKDN2Z4/" target="_blank">Fedora 24</a>
for z Systems / s390x / LinuxONE was released 6/21/2016 together with the Intel version. Thanks to the Fedora
team for closing the time gap between the architectures! The kernel level is kernel-4.5.5-300.<br />
<br />
As usual the <a href="https://dl.fedoraproject.org/pub/fedora-secondary/releases/24/Server/s390x/" target="_blank">download</a>
is available from the Fedoraproject site and the respective mirrors and
known issues are covered in the <a href="http://fedoraproject.org/wiki/Architectures/s390x/24" target="_blank">wiki</a>.

<br />
KVM as well as LinuxONE is now part of the " Request for Enhancement (RFE) Community". So as described in my <a href="https://linuxmain.blogspot.com/2014/04/request-for-enhancement-rfe-community.html">earlier post</a> you can now also submit requirements for LinuxONE and KVM to IBM. To do this open the <a href="https://www.ibm.com/developerworks/rfe/execute?use_case=changeRequestLanding">community start page</a> and then select the "Submit" tab.<br />
After entering in your IBM ID, you can fill in your requirement. In the product pull down please select one of:<br />
<ul>
<li>Linux on System z</li>
<li>IBM LinuxONE</li>
<li>KVM for IBM z Systems</li>
<li>z/VM</li>
</ul>
Fill in the other fields as good as you can and then click on submit.<br />
<br />
Canonical is handling requirements for the <a href="http://www.ubuntu.com/download/server/linuxone">Ubuntu distribution</a> through <a href="https://launchpad.net/ubuntu-z-systems">Launchpad</a>. Open a bug there, put requirement in the title and tag it with s390x.<br />
<br />
Red Hat has a<a href="https://access.redhat.com/solutions/73513"> defined RFE process</a> for their customers. So after logging into RHN follow the instructions to submit a request. <br />
<br />
SUSE requirements can be submitted to their sales reps as well as using the "feedback" button at the bottom of the <a href="https://www.suse.com/products/systemz">SUSE Linux Enterprise Server for System z</a> web site. <br />
