1 SUSE Linux Enterprise ServerSUSE Linux Enterprise Server is a highly reliable, scalable, and secureserver operating system, built to power mission-critical workloads inboth physical and virtual environments. It is an affordable,interoperable, and manageable open source foundation.
Rpm -changelog -qp.rpm.Check the ChangeLog file in the top level of themedia for a chronological log of all changes made to the updatedpackages.Find more information in the docu directory ofthe media of SUSE Linux Enterprise Server 12. This directory includes PDF versions of the SUSE Linux EnterpriseServer 12 Installation Quick Start and Deployment Guides.Documentation (if installed) is available below the/usr/share/doc/ directory of an installedsystem.These Release Notes are identical across all architectures, and themost recent version is always available online at. Some entries arelisted twice, if they are important and belong to more than onesection. 1.3 How to Obtain Source CodeThis SUSE product includes materials licensed to SUSE under the GNUGeneral Public License (GPL). The GPL requires SUSE to provide thesource code that corresponds to the GPL-licensed material.
The sourcecode is available for download at.Also, for up to three years after distribution of the SUSE product, uponrequest, SUSE will mail a copy of the source code. Requests should besent by e-mail to oras otherwise instructed at. SUSEmay charge a reasonable fee to recover distribution costs. 1.4.2 Technology PreviewsTechnology previews are packages, stacks, or features delivered bySUSE. These features are not supported.
They may be functionallyincomplete, unstable or in other ways not suitable for production use.They are mainly included for customer convenience and give customers achance to test new technologies within an enterprise environment.Whether a technical preview will be moved to a fully supported packagelater, depends on customer and market feedback. A technical previewdoes not automatically result in support at a later point in time.Technical previews could be dropped at any time and SUSE is notcommitted to provide a technical preview later in the product cycle.Please, give your SUSE representative feedback, including yourexperience and use case.The guest must pass tpmtis.force=1 on the guestkernel command line. This may be done via the bootloaderconfiguration, typically found in/boot/grub2/grub.cfg. Be aware that YaSTautogenerates this configuration file. Thus better use the KernelParameter tab of the YaST Boot Loader dialog to appendtpmtis.force=1 to the kernel command lineparameters, or edit /etc/default/grub and thenrun grub2-mkconfig -o /boot/grub2/grub.cfg.The host administrator must chmod o+w/sys/class/misc/tpm0/device/cancel. As this permitshost-wide access to cancel TPM commands by unprivileged users, nounprivileged users must be permitted to access the host when it isput into this configuration.
It is anticipated that future versionsof libvirt will perform the privileged access of/sys/class/misc/tpm0/device/cancel on QEMU'sbehalf such that permitting world write access to/sys/class/misc/tpm0/device/cancel will not benecessary. 1.4.2.7 Memory Compression with zswapUsually, when a system's physical memory is exceeded, thesystem moves some memory onto reserved space on a hard drive, called'swap' space. This frees physical memory space for additional use.However, this process of 'swapping' memory onto (and back from) a harddrive is much, much slower than direct memory access, so it can slowdown the entire system.Starting with SLES 12, you can enable the zswapdriver using the boot parameter zswap.enabled=1.The zswap driver inserts itself between the systemand the swap hard drive, and instead of writing memory to a harddrive, it compresses memory.The processes using the pages free the pages or exit.The configured memory limit for zswap isexceeded. In this case, the oldest zswap pagesare written back to disk-based swap (that is, LRU).Memory Allocation IssuesIn theory, it can happen that zswap is not yetexceeding its memory limit, but already fails to allocate memory tostore compressed pages. In that case, it will refuse to compress anynew pages and they will be swapped to disk immediately. Forconfirmation whether this issue is occurring, check the value of/sys/kernel/debug/zswap/rejectallocfail. 1.4.2.11 Linux Paging ImprovementsHigh swapping activity on Linux system, for example whentriggering a file system backup, although the SAP applications aresized to completely fit into the system's main memory.
This results inbad response times on the application level.The pagecachelimit feature is only supported aspart of SUSE Linux Enterprise Server for SAP Applications.You can limit the amount of page cache that the kernel uses if thereis competition between application memory and page cache. Once thepage cache is filled to the configured limit, application memory ismore important and should not be paged out.Two new Linux kernel tunables have been introduced.vm.pagecachelimitmb(/proc/sys/vm/pagecachelimitmb).vm.pagecachelimitignoredirty(/proc/sys/vm/pagecachelimitignoredirty)No pages will be paged out if the memory footprint of the workloadplus the configured page cache limit do not exceed the amount ofphysical RAM in the system. If paging needs to occur, the Linux kernelwill still favor to keep application memory over page cache unless weare below the page cache limit.If there is plenty of free memory, the kernel will continue to use itas page cache in order to speed up file system operations. 1.4.2.12.1 KVM on ppc64leLinux has managed to unify the Operating System layernicely across different architectures. This challenge still exists inthe hypervisor space.KVM solves the universal hypervisor challenge. It is now availableacross all targets that SLES supports.
KVM allows the administratorto create virtual machines in the exact same fashion using the exactsame set of tools on x8664, s390x and ppc64le.This makes SLES the perfect platform for virtualization and cloudscenarios in heterogeneous environments. 1.4.2.13.2 KVM for s390xUsing Linux and virtualization technologies on System z,with good Linux and KVM skills, but limited knowledge of System z andz/VM.KVM is included on the s390x platform as a technology preview.Running Linux with KVM in an LPAR allows x86 skilled administratorsto explore the potential of Linux on the mainframe. KVM on Linuxallows the administrator to create and manage virtual machines byhimself, assign resources and benefit from the workload isolation andprotection, as well as the flexibility of KVM based virtual machines,with the same tools and commands as know from a x86 basedenvironment.Over time, business requirements may increase the need and interestto explore the full potential of the underlying platform. This can beachieved by getting more and more insight into the unique hardwareand performance characteristics of System z, as well as the option tooperate other environments on the mainframe, also in collaborationwith Linux. 1.4.2.13.5 Hot-patching Support for Linux on System z BinariesHot-patch support in gcc implements support for online patching ofmulti-threaded code for Linux on System binaries. It is possible toselect specific functions for hot-patching using a functionattribute and to enable hot-patching for all functions (-mhotpatch ) via command line option. Becauseenabling of hot-patching has negative impact on software size andperformance it is recommended to use hot-patching for specificfunctions and not to enable hot-patch support in general.For online documentation, see.

2.1.1 Avoid Adding Packages When Activating a Module RepositoryWhen adding a module repository such as Public Cloud thegraphical installer (YaST Qt UI) automatically selects recommendedpackages. Often this is not expected by the user.To work around this behavior, disable the installation of recommendedpackages in the installer (YaST Qt UI) or use the text-mode installer(YaST ncurses UI) that by default does not autoinstall recommendedpackages ('Install Recommended Packages for Already Installed Packages'is deactivated).Use English or some other non-CJK language for installation thenswitch to the CJK language later on a running system usingYaST+System+Language.Use your CJK language during installation, but do not choose TextMode in the boot loader using F3 Video Mode. Select one of the otherVGA modes instead.
Select the CJK language of your choice using F2Language, add textmode=1 to the boot loader command-line and startthe installation.Use graphical installation (or install remotely via SSH or VNC).bootloader, kernel and kernel modules must be signed.kexec and kdump are disabled.Hibernation (suspend on disk) is disabled.Access to /dev/kmem and/dev/mem is not possible, not even as root user.Access to I/O port is not possible, not even as root user.
