Table of Contents
This chapter describes the new features that are introduced by Oracle Linux 6 Update 6.
Oracle Linux 6 Update 6 ships with three sets of kernel packages:
Unbreakable Enterprise Kernel Release 2
(kernel-uek-2.6.39-400.215.10.el6uek) for i386
Unbreakable Enterprise Kernel Release 3
(kernel-uek-3.8.13-44.1.1.el6uek) for
x86-64
Red Hat Compatible Kernel (kernel-2.6.32-504.el6) for i386 and
x86-64
By default, both the Unbreakable Enterprise Kernel and the Red Hat Compatible Kernel for the specific architecture (i386 or x86-64) are installed and the system boots the Unbreakable Enterprise Kernel.
The ISO image for Oracle Linux 6 Update 6 for i386 includes the Red Hat Compatible Kernel and the Unbreakable Enterprise Kernel Release 2 but not the Unbreakable Enterprise Kernel Release 3, which does not support i386.
The ISO image for Oracle Linux 6 Update 6 for x86-64 includes the Red Hat Compatible Kernel and the Unbreakable Enterprise Kernel Release 3 but not the Unbreakable Enterprise Kernel Release 2.
To make your system boot the Red Hat Compatible Kernel by default:
Edit /etc/grub.conf and change the value
of the default parameter to indicate the
Red Hat Compatible Kernel. (Each entry for a bootable kernel
in the file starts with a title
definition. The entries are effectively numbered from 0
upwards, where 0 corresponds to the first entry in the file,
1 to the second entry, and so on. To view the GRUB manual,
use the info grub command.)
Edit /etc/sysconfig/kernel and change the
setting for the default kernel package type from
DEFAULTKERNEL=kernel-uek to
DEFAULTKERNEL=kernel.
The Unbreakable Enterprise Kernel Release 2 (UEK R2) is based on the upstream kernel 3.0.36 stable source tree.
The Unbreakable Enterprise Kernel supports a wide range of hardware and devices. In close cooperation with hardware and storage vendors, a number of device drivers have been updated by Oracle in the 2.6.39-400 kernel. For details, see the Oracle Linux Unbreakable Enterprise Kernel Release 2 Quarterly Update 5 Release Notes.
The Unbreakable Enterprise Kernel Release 3 (UEK R3) is based on the upstream kernel 3.8.13 stable source tree. For more information about UEK R3, see the Oracle Linux Unbreakable Enterprise Kernel Release 3 Release Notes.
A very large number of changes have taken place in mainline Linux between 3.0.x, on which UEK R2 is based, and 3.8.13, on which UEK R3 is based. For details of all these changes, see the kernel change logs that the Linux Kernel Newbies maintain at http://kernelnewbies.org/LinuxVersions.
UEK R3 includes the following major improvements over UEK R2:
Integrated DTrace support in the UEK R3 kernel and user-space tracing of DTrace-enabled applications.
Device mapper support for an external, read-only device as the origin for a thinly-provisioned volume.
The loop driver provides the same I/O
functionality as dm-nfs by extending
the AIO interface to perform direct I/O. To create the
loopback device, use the losetup
command instead of dmsetup. The
dm-nfs module is not provided with UEK
R3.
Btrfs send and receive subcommands allow you to record the differences between two subvolumes, which can either be snapshots of the same subvolume or parent and child subvolumes.
Btrfs quota groups (qgroups) allow you to set different size limits for a volume and its subvolumes.
Btrfs supports replacing devices without unmounting or otherwise disrupting access to the file system.
Ext4 quotas are enabled as soon as the file system is mounted.
TCP controlled delay management (CoDel) is a new active queue management algorithm that is designed to handle excessive buffering across a network connection (bufferbloat). The algorithm is based on for how long packets are buffered in the queue rather than the size of the queue. If the minimum queuing time rises above a threshold value, the algorithm discards packets and reduces the transmission rate of TCP.
TCP connection repair implements process checkpointing and restart, which allows a TCP connection to be stopped on one host and restarted on another host. Container virtualization can use this feature to move a network connection between hosts.
TCP and STCP early retransmit allows fast retransmission (under certain conditions) to reduce the number of duplicate acknowledgements.
TCP fast open (TFO) can speed up the opening of successive TCP connections between two endpoints by eliminating one round time trip (RTT) from some TCP transactions.
The TCP small queue algorithm is another mechanism intended to help deal with bufferbloat. The algorithm limits the amount of data that can be queued for transmission by a socket.
The secure computing mode feature
(seccomp) is a simple sandbox
mechanism that, in strict mode, allows a thread to
transition to a state where it cannot make any system
calls except from a very restricted set
(_exit(), read(),
sigreturn(), and
write()) and it can only use file
descriptors that were already open. In filter mode, a
thread can specify an arbitrary filter of permitted
systems calls that would be forbidden in strict mode.
Access to this feature is by using the
prctl() system call. For more
information, see the prctl(2) manual
page.
The OpenFabrics Enterprise Distribution (OFED) 2.0 stack supports the following protocols:
SCSI RDMA Protocol (SRP) enables access to remote SCSI devices via remote direct memory access (RDMA)
iSCSI Extensions for remote direct memory access (iSER) provide access to iSCSI storage devices
Reliable Datagram Sockets (RDS) is a high-performance, low-latency, reliable connectionless protocol for datagram delivery
Sockets Direct Protocol (SDP) supports stream sockets for RDMA network fabrics
Ethernet over InfiniBand (EoIB)
IP encapsulation over InfiniBand (IPoIB)
Ethernet tunneling over InfiniBand (eIPoIB)
The OFED 2.0 stack also supports the following RDS features:
Async Send (AS)
Quality of Service (QoS)
Automatic Path Migration (APM)
Active Bonding (AB)
Netfilter (NF)
Paravirtualization support has been enabled for Oracle Linux guests on Windows Server 2008 Hyper-V or Windows Server 2008 R2 Hyper-V.
The Virtual Extensible LAN (VXLAN) tunneling protocol overlays a virtual network on an existing Layer 3 infrastructure to allow the transfer of Layer 2 Ethernet packets over UDP. This feature is intended for use by a virtual network infrastructure in a virtualized environment. Use cases include virtual machine migration and software-defined networking (SDN).
The kernel version in UEK R3 is based on the mainline Linux
kernel version 3.8.13. Low-level system utilities that
expect the kernel version to start with 2.6 can run without
change if they use the UNAME26
personality (for example, by using the
uname26 wrapper utility, which is
available in the uname26 package).
For more information about the new functionality that UEK R3 provides, see the Oracle Linux Unbreakable Enterprise Kernel Release 3 Release Notes.
The hyperv-daemons package, which includes the
hypervfcopyd, hypervkvpd, and
hypervvssd packages, provides the Hyper-V file-copy, key-value pair
(KVP), and volume shadow copy service (VSS) daemons for an Oracle Linux guest that is
running under Hyper-V on a Microsoft Windows host.
The file-copy daemon (hv_fcopy_daemon) implements a file-copying
service (hypervfcopyd) between the host and a guest.
The KVP daemon (hv_kvp_daemon) implements the
hypervkvpd service, which uses the virtual machine bus
(VMbus) to send information about a guest to the host.
The VSS daemon (hv_vss_daemon) implements the
hypervvssd service, which allows you to create snapshots and backups of
volumes from the host without preventing processes that are running in a guest from writing
to or reading from those volumes.
Reboot the guest after installing the package.
The System Security Services Daemon (SSSD) now supports the following features when using Oracle Linux clients with Active Directory (AD):
Dynamic updates to DNS.
Group and user lookups of NetBIOS names.
Site discovery of domain controllers.
User and group resolution and user authentication for trusted domains within a single AD forest.
If you need to remove the Red Hat Compatible Kernel (RHCK) from a system, you can use
the kernel-transition package to prepare the system for removing the RHCK
without removing dependent packages such as bluez,
fuse, and irqbalance that might be needed for system
operation. The kernel-transition package does not contain any files
itself but instead it transfers the package dependencies from the kernel
package to the kernel-uek package.
You must have subscribed the system to be transitioned to the
ol6_latest channel on ULN.
Because the xorg-x11-drv-nouveau package requires
kernel-drm-nouveau version 16 but kernel-uek
provides kernel-uek-drm-nouveau version 12, removing the RHCK also
removes xorg-x11-drv-nouveau. If you use this procedure on systems with
Nvidia graphics hardware, the graphical interface will become low resolution and slow.
To transition a system from the RHCK to the UEK:
Install the kernel-transition package on the system:
# yum install kernel-transitionThis command changes the dependencies for important packages from the RHCK to the UEK.
Remove the RHCK:
# yum remove kernelThis command prompts you before removing remaining packages that depend on the RHCK.
When yum prompts you to remove a package, only remove packages
that relate to the kernel package. If you are prompted to remove a
package that your system
requires, enter n to prevent the package being removed. You
should also retain any other dependent packages.
Running the yum update command subsequently will update only the UEK.
If you want to reinstall the RHCK, use the following command:
# yum install kernelYou can also use kernel-transition with kickstart installation.
Include the following lines in the %packages section to install the
kernel-uek and kernel-transition packages but not
the kernel package:
-kernel kernel-transition
If you create a customized installation ISO, you can replace the
kernel package with kernel-transition so that
dependency resolution will pull in kernel-transition instead of
kernel. If kernel-transition is present on the
installation media, it cannot be installed accidentally because it provides a kernel version
that is lower than that of any RHCK.
Technology Preview features are still under development but are made available for testing and evaluation purposes and to give the features wider exposure. These features are not supported under Oracle Linux support subscriptions and are not suitable for production use.
The following Technology Preview features are currently not supported under Oracle Linux 6 and might not be functionally complete:
DIF/DIX support for SCSI
FS-Cache
fsfreeze
IPv6 support in IPVS
LVM API
LVM RAID support
Open multicast ping (omping)
System Information Gatherer and Reporter (SIGAR)
Trusted Platform Module (TPM)
Trusted Boot
vios-proxy
The following technology preview features are provided with UEK R2:
Distributed Replicated Block Device (Oracle Linux 6 only)
Distributed Replicated Block Device (DRBD) shared-nothing, synchronously replicated block device (RAID1 over network), designed to serve as a building block for high availability (HA) clusters. It requires a cluster manager (for example, pacemaker) to implement automatic failover.
Kernel module signing facility
Applies cryptographic signature checking to modules on module load, checking the signature against a ring of public keys compiled into the kernel. GPG is used to do the cryptographic work and determines the format of the signature and key data.
The kernel module signing facility is a supported feature in the UEK R3 distribution.
Linux Containers (Oracle Linux 6 and x86-64 only)
Based on the Linux cgroups and name spaces functionality,
Linux Containers (LXC) allow you to safely and securely
run multiple applications or instances of an operating
system on a single host without risking them interfering
with each other. Containers are lightweight and
resource-friendly, which saves both rack space and power.
In order to get started with containers, you need to
install the lxc package, which is
included in the package repository of the Unbreakable
Enterprise Kernel.
LXC is a supported feature in the UEK R3 distribution.
Transcendent memory
Transcendent Memory (tmem) provides a new approach for improving the utilization of physical memory in a virtualized environment by claiming underutilized memory in a system and making it available where it is most needed. From the perspective of an operating system, tmem is fast pseudo-RAM of indeterminate and varying size that is useful primarily when real RAM is in short supply. To learn more about this technology and its use cases, see the Transcendent Memory project page on oss.oracle.com: http://oss.oracle.com/projects/tmem/

Table of Contents
This chapter describes the fixed and known issues for Oracle Linux 6 Update 6.
Run the yum update command regularly to ensure that the latest bug fixes and security errata are installed on your system.
For details of the fixed and known issues with the Unbreakable Enterprise Kernel Release 3, see the Oracle Linux Unbreakable Enterprise Kernel Release 3 Release Notes.
For details of the fixed and known issues with the Unbreakable Enterprise Kernel Release 2 Quarterly Update 5, see the Oracle Linux Unbreakable Enterprise Kernel Release 2 Quarterly Update 5 Release Notes.
The following sections describe the major issues that are fixed in this update:
ULN registration during firstboot now also supports Ksplice registration. (Bug ID 19626387)
The vtimestamp() function now returns the
correct value for the amount of time that the current thread
has been running on a CPU, excluding the time spent performing
DTrace predicates and actions. (Bug ID 17741477)
A race condition that could occur when priming the
last_data value has been corrected. This
fix ensures correct operation of the random number generator
when compliance with Federal Information Processing Standard
(FIPS) Publication 140-2 is enabled. (Bug ID 17776875)
To simplify Kdump configuration, support for the
crashkernel=auto kernel parameter was
enabled in UEK R3 Quarterly Update 1.
Xen does not support the crashkernel=auto parameter.
If the crashkernel=auto parameter is
enabled, the output of the dmesg command
shows crashkernel=XM@0M. This is normal.
When configuring a crashkernel setting
for the UEK prior to UEK R3 Quarterly Update 1, using the
crashkernel=auto parameter causes Kdump
to fail to start. Only standard settings such as
crashkernel=128M@32M are supported.
(Bug ID 13495212, 17616874)
If a version of the udev package prior to
udev-147-2.42.el6.arch.rpm is installed, a
message similar to the following might be recorded in
dmesg or
/var/log/messages at boot time:
udevd (pid): /proc/pid/oom_adj is deprecated, please use /proc/pid/oom_score_adj instead.
To prevent the message from occurring, ensure that
udev-147-2.42.el6.arch.rpm or later is
installed. (Bug ID 13655071, 13712009)
When using a Broadcom NetXtreme II 10Gbps network adapter
(which uses the bnx2x driver) in a bridge,
it is no longer necessary to disable Transparent Packet
Aggregation (TPA) by including options bnx2x
disable_tpa=1 in
/etc/modprobe.conf. (Bug ID 14626070)
The following sections describe known issues in this update.
The avahi-daemon fails to start with UEK R2 and messages such as
the following are logged:
avahi-daemon[PID]: SO_REUSEPORT failed: Protocol not available avahi-daemon[PID]: Failed to create server: No suitable network protocol available
The workaround is to comment out the
disallow-other-stacks entry in
/etc/avahi/avahi-daemon.conf as shown here:
#disallow-other-stacks=yes
(Bug ID 19712845)
When booting UEK R2 as a PVHVM guest, you can safely ignore
the kernel message register_vcpu_info failed:
err=-38, which might be displayed. (Bug ID 13713774)
For a description of the known issues for btrfs with Unbreakable Enterprise Kernel Release 2 Quarterly Update 5, see the Oracle Linux Unbreakable Enterprise Kernel Release 2 Quarterly Update 5 Release Notes.
For a description of the known issues for btrfs with Unbreakable Enterprise Kernel Release 3 Quarterly Update 3, see the Oracle Linux Unbreakable Enterprise Kernel Release 3 Quarterly Update 3 Release Notes.
On some hardware, the console may appear to hang during the
boot process after starting udev. However,
the system does boot properly and is accessible. A workaround
to this problem is to add nomodeset as a
kernel boot parameter in /etc/grub.conf.
(Bug ID 10094052, 13485328)
For the Unbreakable Enterprise Kernel,
deadline is the default I/O scheduler.
For the Red Hat Compatible Kernel, cfq is
the default I/O scheduler.
The default NFS mount option has changed to NFS v4. To mount an NFS v3 volume (the default in Oracle Linux 5), use the following mount options:
-o vers=3,mountproto=tcp
Oracle Linux 6 defaults to reverse path filtering in strict
mode. Some Oracle products and network storage devices work
more reliably with reverse path filtering in loose mode. To
enable loose mode, issue the following command (where
iface is the network interface, for
example, eth1).
# sysctl net.ipv4.conf.iface.rp_filter=2
The default setting is 1 for strict mode. (Bug ID 10649976)
The UEK does not support the dm-cache and
dm-era device mapper targets. (Bug ID 19611720)
If you want to use the DTrace-enabled version of the UEK
R2 kernel, subscribe your system to the Dtrace for Oracle
Linux 6 (x86_64) - Latest channel
(ol6_x86_64_Dtrace_latest) but not to
the Oracle Linux 6 Dtrace Userspace Tools (x86_64) -
Latest channel
(ol6_x86_64_Dtrace_userspace_latest).
The ol6_x86_64_Dtrace_userspace_latest
channel is provided for use with UEK R3 and installs that
kernel as a dependency.
Using kill -9 to terminate dtrace can leave breakpoints outstanding in processes being traced, which might sooner or later kill them.
Argument declarations for static probe definitions cannot
be declared with derived types such as
enum, struct, or
union.
The following compiler warning can be ignored for static
probe definition arguments of type
string (which is a D type but not a C
type):
provider_def.h:line#: warning: parameter names (without types) in function declaration
To make an Oracle Linux Release 6 Update 6 system compliant with Federal Information Processing Standard (FIPS) Publication 140-2, perform the following steps:
Install the dracut-fips package:
# yum install dracut-fips
Recreate the initramfs file system:
# dracut -f
Identify either the device file path
(device) under
/dev of your system's boot device or
its UUID (uuid) by using
ls -l to examine the entries under
/dev/disk/by-uuid.
Add either a
boot=
entry or a
deviceboot=UUID=
entry for the boot device to the uuidkernel
command line in /etc/grub.conf.
Add a fips=1 entry to the
kernel command line in
/etc/grub.conf to specify strict FIPS
compliance.
Disable prelinking by setting
PRELINKING=no in
/etc/sysconfig/prelink.
Remove all existing prelinking from binaries and libraries:
# prelink -ua
Install the openssh-server-fips and
openssh-client-fips packages and their
dependent packages:
# yum install openssh-server-fips openssh-client-fipsShut down and reboot the system.
If you specify fips=1 on the kernel
command line but omit a valid boot=
entry, the system crashes because it cannot locate the
kernel's .hmac file.
If you do not disable and remove all prelinking, users
cannot log in and /usr/sbin/sshd does not
start.
(Bug ID 17759117)
You might see a message similar to the following during the first reboot of an HP ProLiant server:
[Firmware Bug]: the BIOS has corrupted hw-PMU resources (MSR 186 is 43003c)
You can safely ignore this message. The functionality and performance of the operating system and the server are not affected.
The inline data feature that allows the data of small files to be stored inside their inodes is not yet available with the UEK. The -O inline_data option to the mkfs.ext4 and tune2fs commands is not supported. (Bug ID 17210654)
The gcc-libraries package has been replaced by individual packages
for libatomic, libcilkrts, and
libitmed. (Bug ID 19829494)
Selecting all packages in certain groups during installation might not show the correct package count. (Bug ID 11684244)
Some server hardware does not support the Intel TCO watchdog driver. dmesg might display messages such as the following at boot time:
iTCO_vendor_support: vendor-support=0 iTCO_wdt: Intel TCO WatchDog Timer Driver v1.05 iTCO_wdt: failed to reset NO_REBOOT flag, reboot disabled by hardware iTCO_wdt: No card detected intel_rng: FWH not detected
To suppress this warning at boot time, disable the TCO
watchdog timer driver by adding the following line to
/etc/modprobe.d/blacklist-watchdog:
blacklist iTCO_wdt
On virtualized systems that are built on Xen version 3, including all releases of Oracle VM 2 including 2.2.2 and 2.2.3, disk synchronization requests for ext3 and ext4 file systems result in journal corruption with kernel messages similar to the following being logged:
blkfront: barrier: empty write xvda op failed blkfront: xvda: barrier or flush: disabled
In addition, journal failures such as the following might be reported:
Aborting journal on device xvda1
The workaround is to add the mount option barrier=0 to all ext3 and ext4 file systems in the guest VM before upgrading to UEK R3. For example, you would change a mount entry such as:
UUID=4e4287b1-87dc-47a8-b69a-075c7579eaf1 / ext3 defaults 1 1
so that it reads:
UUID=4e4287b1-87dc-47a8-b69a-075c7579eaf1 / ext3 defaults,barrier=0 1 1
This issue does not apply to Xen 4 based systems, such as Oracle VM 3. (Bug ID 17310816, 17313428)
By default, the Kernel Dump service (Kdump) is enabled is enabled and configured for
UEK R3 on x86-64 using the crashkernel=auto setting, but must be
manually configured for UEK R2 on i386, which does not support
crashkernel=auto.
The following boot-time message indicates that Kdump needs to be configured.
kdump: No crashkernel parameter specified for running kernel
To prevent this message from being displayed, use the Kernel Dump Configuration GUI (system-config-kdump) to configure or disable Kdump. (Bug ID 16242031)
An updated kernel-uek-headers package is provided that reinstates
kernel-headers to avoid certain build problems. This new version of
kernel-uek-headers effectively hides older versions of the package in
the repository. You no longer need to exclude kernel-uek-headers in the
yum configuration for new installations if you had to do this previously. (Note that you
do not require kernel-uek-headers to build kernel modules.) (Bug ID
19265353)
The Linux Containers package (lxc) is available for the x86-64
architecture with UEK R3 but not i386.
The correct operation of containers might require that you completely disable SELinux on the host system. For example, SELinux can interfere with container operation under the following conditions:
Running the halt or
shutdown command from inside the
container hangs the container or results in a
permission denied error. (An
alternate workaround is to use the init
0 command from inside the container to shut
it down.)
Setting a password inside the container results in a
permission denied error, even when
run as root.
You want to allow ssh logins to the
container. ssh logins are possible
with SELinux enabled if you install the
lxc-0.9.0-2.0.5 package (or later
version of this package).
To disable SELinux on the host:
Edit the configuration file for SELinux,
/etc/selinux/config and set the
value of the SELINUX directive to
disabled.
Shut down and reboot the host system.
The default location for a container's configuration has
changed from
/etc/lxc/
to
name/container/
in namelxc 0.8.0 onward.
To start a container that you created with a previous update of Oracle Linux, specify the -f option to lxc-start, for example:
# lxc-start -n ol6u3 -f /etc/lxc/ol6u3/config
To convert an existing container to use the new location:
Move the container's configuration directory to
/container/:
name
# mv /etc/lxc/name /container Edit the
/container/ file and
change the values of any name/configlxc.rootfs and
lxc.mount parameters to refer to
/container instead of /etc/lxc.
For example, the config file might contain the following
entries:
lxc.rootfs = /etc/lxc/example/rootfs lxc.mount.entry=/lib /etc/lxc/example/rootfs/lib none ro,bind 0 0 lxc.mount.entry=/usr/lib /etc/lxc/example/rootfs/usr/lib none ro,bind 0 0 lxc.mount.entry=/lib64 /etc/lxc/example/rootfs/lib64 none ro,bind 0 0 lxc.mount.entry=/usr/lib64 /etc/lxc/example/rootfs/usr/lib64 none ro,bind 0 0
You would change these entries to read:
lxc.rootfs = /container/example/rootfs lxc.mount.entry=/lib /container/example/rootfs/lib none ro,bind 0 0 lxc.mount.entry=/usr/lib /container/example/rootfs/usr/lib none ro,bind 0 0 lxc.mount.entry=/lib64 /container/example/rootfs/lib64 none ro,bind 0 0 lxc.mount.entry=/usr/lib64 /container/example/rootfs/usr/lib64 none ro,bind 0 0
After converting the container, you do not need to specify the -f option to lxc-start. (Bug ID 15967411)
Attempting to create an lxc-oracle
container on a remote file system mounted using NFS v4
fails. In addition, attempting to mount a remote file
system using NFS v4 from within an
lxc-oracle container also fails. The
workaround is to use NFS v3 instead. (Bug ID 16316266)
The Mellanox ConnectX core, Ethernet, and InfiniBand drivers are supported only for the x86-64 architecture. (Bug ID 16228063)
Both the mlnx_en and ofa
packages contain mlx4_core. Only one of
these packages should be installed. Attempting to install both
packages on a single server results in a package conflict
error. If you have a Mellanox Ethernet Controller, install
mlnx_en. If you have a Mellanox InfiniBand
Controller, install ofa. If your system has
both controllers, use ofa as it supports
both the Ethernet and InfiniBand controllers.
If the SELinux policy packages have not been updated recently,
Cluster Ready Services (CRS) might fail to start with messages
such as the following in /var/log/messages:
SELinux is preventing /usr/lib/oracleasm/oracleasm-instantiate-disk from associate access on the filesystem DATA1.
The solution is to upgrade the
selinux-policy and
selinux-policy-targeted packages to ensure
that you are running a version no earlier than
3.7.195.0.1.el6_4.5:
# yum update 'selinux-policy*'
After upgrading the packages, reboot the system. (Bug ID 13925445)
On an x86-64 system, if you install the
pam.i386 package either manually or via a
package dependency, and the
oracle-rdbms-server-11gR2-preinstall
package is also selected, this overwrites the settings for
Oracle Database in
/etc/security/limits.conf. This is most
likely to occur during a Kickstart-automated installation that
includes non-standard packages. To restore the settings, run
the
oracle-rdbms-server-11gR2-preinstall-verify
script. (Bug ID 14212822)
PVHVM guests on Oracle VM 3.0 crash during Oracle Database
installation if the value of the maximum memory
(maxmem) parameter set for the guest is
greater than the amount specified at boot time
(memory). To avoid this issue, ensure that
the values of the maxmem and
memory parameters are the same. This issue
has been resolved in Oracle VM 3.1.1. (Bug ID 13396734,
13970935)
The Unbreakable Enterprise Kernel adds support for PV drivers
in an HVM guest (PVHVM) on Oracle VM. The default is to
present only PV drivers when running in an HVM guest. To run
kernel-uek fully hardware virtualized,
including the drivers, add the parameter
xen_emul_unplug=never to the boot
parameters in /etc/grub.conf, for example:
kernel /vmlinuz-2.6.32-300.2.1.el6uek ro root=/dev/VolGroup00/LogVol00 xen_emul_unplug=never
Adding this parameter makes the kernel also present the
emulated drivers as previously (for example, the
8139cp network driver).
In certain cases, after successfully completing installation and rebooting the system, it is possible for errors such as the following to occur:
Error in sys.excepthook: Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/meh/handler.py", line 161, in (lambda) File "/usr/lib/anaconda/exception.py", line 44, in handleException File "/usr/lib/python2.6/site-packages/meh/handler.py", line 106, in handleException File "/usr/lib/anaconda/gui.py", line 1169, in mainExceptionWindow ImportError: No module named ui.gui

if ((event.keyval == gtk.keysyms.KP_Delete
ImportError: No module named keysymsThese errors can safely be ignored.
If you enable the OFED stack and the RDMA service but the
version of the RDMA package is lower than
rdma‑3.10‑3.0.2.el6, the RDMA
service does not load the mlx4_ib module
automatically.
To configure the RDMA service to load the
mlx4_ib module at boot time:
Edit /etc/rdma/rdma.conf and set the
entry MLX4_LOAD=yes in this file.
To make the change take effect, restart the RDMA service or reboot the system.
Certain network operations that utilize receive packet steering could cause errors on the system. (Bug ID 11071685)
For the Unbreakable Enterprise Kernel, the default setting is
kernel.sched_compat_yield=1.
For the Red Hat Compatible Kernel, the default setting is
kernel.sched_compat_yield=0.
To set the serial console in a hardware virtualized guest, use following settings in the guest:
Add the following parameters to the kernel boot line in
/etc/grub.conf:
console=tty0 console=ttyS0,57600n8
Add the following line to /etc/securetty:
ttyS0
Stopping or restarting the rdma service while the RDS Shared
Receive Queue (SRQ; a feature of the OFED 2.0 stack) is in use can cause a system
panic.
(Bug ID 18250700, 19479464)
Xen does not support the crashkernel=auto parameter for Kdump
configuration.
(Bug ID 18174580)
Releases of Oracle Linux prior to Oracle Linux 5 supplied a hugemem kernel to allow a system to address up to 64 GB of memory in 32-bit mode. The hugemem kernel is no longer available in Oracle Linux 5 and later releases.
The Unbreakable Enterprise Kernel (UEK) supports a maximum of 16 GB of memory for 32-bit kernels on bare metal and hardware virtualized machine (HVM) systems, and 8 GB for fully paravirtualized machine (PVM) systems. 32-bit PVM guest operating systems must be located in the first 128 GB of physical memory on the host.
The Red Hat Compatible Kernel (RHCK) has the same limitations, except that PVM systems can have up to 16 GB of memory. The limitation of 8 GB for PVM on UEK was chosen for reasons of reliability.
A 32-bit system uses the PAE (physical address extension) memory feature to map physical memory beyond 4 GB into the 32-bit address space that is available to each process. A 64-bit system can address memory beyond 4 GB without requiring an extra layer of memory abstraction.
Oracle Linux on x86-64 includes 32-bit libraries, which allow applications built for both 64-bit and 32-bit Linux to run on the same system. This capability provides scalability to virtually unlimited memory sizes, while retaining the ability to run 32-bit applications. Oracle recommends this configuration for any system with more than 4 GB of memory. (Bug ID 16974301)
Registering an Oracle Linux guest running under Virtual Box with the Unbreakable
Linux Network (ULN) might fail with a server communication error. The workaround is to run
the following command as root on the guest:
# echo "uuid=`uuidgen -t`" >> /etc/sysconfig/rhn/up2date
You can then run uln_register again. (Bug ID 14696776)
Following the first reboot after installing Oracle Linux 6,
you are prompted to register your system with ULN. If you did
not configure your network during the installation, the
registration process to ULN cannot succeed. To register your
system, log in as root, configure the
system's network manually, and run
uln_register.
The expiration date for the Oracle Linux 6 GPG key has been extended in this update.
If you install the rhn-client-tools package and the installed version
of the oraclelinux-release package is from a previous update, you might
see a transaction error such as the following:
Transaction Check Error: file /etc/pki/rpm-gpg/RPM-GPG-KEY from install of rhn-client-tools-1.0.0.1-18.0.2.el6.noarch conflicts with file from package oraclelinux-release-6:6Server-5.0.2.x86_64
To avoid this error, install both the oraclelinux-release and
rhn-client-tools packages from this update
(oraclelinux-release-6Server-6.0.2 or later and
rhn-client-tools-1.0.0.1-18.0.2 or later).
An XFS file system can become corrupted if all of its inodes are used. (Bug ID 19217280)
Growing an XFS file system can cause a system panic. (Bug ID 19247345, 19427033)
Table of Contents
This chapter describes how to upgrade your system to Oracle Linux 6 Update 6.
On i386 systems, upgrading from Oracle Linux 6 GA or a previous update to Oracle Linux 6 is supported for the Unbreakable Enterprise Kernel Release 2 and the Red Hat Compatible Kernel. The Unbreakable Enterprise Kernel Release 3 is not supported on the i386 architecture.
On x86-64 systems, upgrading from a previous update to Oracle Linux 6 or from Oracle Linux 6 GA or is supported for the Unbreakable Enterprise Kernel Release 2, the Unbreakable Enterprise Kernel Release 3, and the Red Hat Compatible Kernel.
Upgrading from a beta release is not supported.
In-place upgrading from a major version of Oracle Linux 5 or earlier is not supported. Although Anaconda provides an option to perform an upgrade, fresh installation is strongly recommended.
If you have an Oracle Linux 5.8 system, you can use new features in the Unbreakable Enterprise Kernel Release 2 without upgrading to Oracle Linux 6 as Oracle Linux 5.8 includes the Unbreakable Enterprise Kernel Release 2. You cannot use features from the Unbreakable Enterprise Kernel Release 3 as this kernel is not available for Oracle Linux 5.8.
You can download a full Oracle Linux installation media image from the Oracle Software Delivery Cloud at http://edelivery.oracle.com/linux. You can also obtain Oracle Linux packages from the Unbreakable Linux Network (ULN) and the Oracle Public Yum server.
You have the option of registering a system with ULN when you install Oracle Linux 6 on a system. To register with ULN after installation, use the uln_register command.
To obtain Oracle Linux updates from ULN, you must have an Oracle Linux support subscription. For more information about ULN, see http://linux.oracle.com.
From Oracle Linux 6 Update 5, ULN registration subscribes a server to the Oracle Linux
6 latest channel and either the UEK R2 latest channel
(ol6_i386_UEK_latest) for i386 or the UEK R3 latest channel
(ol6_UEKR3_latest) for x86-64.
If you want to install UEK R3 on a ULN-registered x86-64 system that is currently
running UEK R2, manually subscribe the system to the UEK R3 latest channel
(ol6_UEKR3_latest) and unsubscribe the server from the UEK R2 latest
channel (ol6_x86_64_UEK_latest) before running yum
update.
ULN also provides channels for Oracle-specific software
packages such as Oracle's ASMlib user-space
package and the Oracle Instant Client. To enable access to
these packages, log in to ULN and subscribe your system to the
Oracle Software channel.
Oracle also provides all errata and updates for Oracle Linux via the Public Yum service, which includes updates to the base distribution, but does not include Oracle-specific software. You do not require an Oracle Linux support subscription to use this service. For more information on how to obtain updates from Public Yum, see http://public-yum.oracle.com.
By default, all new installations of Oracle Linux 6 Update 6 are automatically configured to use the public yum update service. If you subsequently register the system with ULN, the public yum service is automatically disabled.
The following entries in the /etc/yum.repos.d/public-yum-ol6.repo
file enable you to download the latest available packages for Oracle Linux 6 and UEK R2:
[ol6_latest] name=Oracle Linux $releasever Latest ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1 [ol6_UEK_latest] name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1
The following entries in the /etc/yum.repos.d/public-yum-ol6.repo
file enable you to download the latest available packages for Oracle Linux 6 and UEK R3:
[ol6_latest] name=Oracle Linux $releasever Latest ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1 [ol6_UEKR3_latest] name=Latest Unbreakable Enterprise Kernel Release 3 for Oracle Linux $releasever ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEKR3/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1
The ol6_UEKR3_latest repository is not
available for i386 systems.
If you want to install packages from the playground or OFED
repositories, add the following entries and enable them by
setting the value of enabled to 1:
[ol6_playground_latest] name=Latest mainline stable kernel for Oracle Linux 6 ($basearch) - Unsupported baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/playground/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=0 [ol6_ofed_UEK] name=OFED supporting tool packages for Unbreakable Enterprise Kernel on Oracle Linux 6 ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/ofed_UEK/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=0
On a freshly installed Oracle Linux 6 Update 6 system, the
public-yum-ol6.repo file uses the
variables uek and
uekr3 to enable or disable
ol6_UEK_latest and
ol6_UEKR3_latest. For an i386 system, the
value of uek is set to 1 in
/etc/yum/vars/uek to enable
ol6_UEK_latest and the value of
uekr3 is set to 0 in
/etc/yum/vars/uekr3 to disable
ol6_UEKR3_latest. For an x86-64 system,
the value of uekr3 is set to 1 in
/etc/yum/vars/uekr3 to enable
ol6_UEKR3_latest and the value of
uek is set to 0 in
/etc/yum/vars/uek to disable
ol6_UEK_latest.
If you subsequently register the system with ULN, the
repository entries in public-yum-ol6.repo
are disabled and the values of both uek
and uekr3 are set to 0.
Oracle Linux 6 Update 6 contains three distinct repository sources on the installation media for the Unbreakable Enterprise Kernel Release 2, the Unbreakable Enterprise Kernel Release 3, and the Red Hat Compatible Kernel.
To configure yum to use both an Unbreakable
Enterprise Kernel Release 2 and the Red Hat Compatible Kernel
repositories from an ISO image of the installation media,
create the file /etc/yum.repos.d/Media.repo
containing entries similar to the following:
[ol6_base_media] name=Oracle Linux 6 Update 6 Base Media baseurl=file:///media/ISOimage/Server gpgkey=file:///media/ISOimage/RPM-GPG-KEY gpgcheck=1 enabled=1 [ol6_uek_media] name=Oracle Linux 6 Update 6 UEK Media baseurl=file:///media/ISOimage/UEK2 gpgkey=file:///media/ISOimage/RPM-GPG-KEY gpgcheck=1 enabled=1
To configure yum to use both an Unbreakable
Enterprise Kernel Release 3 and the Red Hat Compatible Kernel
repositories from an ISO image of the installation media,
create the file /etc/yum.repos.d/Media.repo
containing entries similar to the following:
[ol6_base_media] name=Oracle Linux 6 Update 6 Base Media baseurl=file:///media/ISOimage/Server gpgkey=file:///media/ISOimage/RPM-GPG-KEY gpgcheck=1 enabled=1 [ol6_uekr3_media] name=Oracle Linux 6 Update 6 UEK Media baseurl=file:///media/ISOimage/UEKR3 gpgkey=file:///media/ISOimage/RPM-GPG-KEY gpgcheck=1 enabled=1
The ol6_uekr3_media repository is not
available for i386 systems.
Adjust the value of the baseurl and
gpgkey parameters to match the mount point
of the ISO image on your system. If you do not require one of
the repositories, set the value of the corresponding
enabled parameter to 0.
Oracle Linux 6 Update 6 ships with the latest Unbreakable Enterprise Kernel Release 2 for i386 and Unbreakable Enterprise Kernel Release 3 for x86-64. If you upgrade your system from the installation media, there are four upgrade scenarios:
If the UEK R2 or UEK R3 is not currently installed on the system, only the latest Red Hat Compatible Kernel is installed. The UEK R2 or UEK R3 kernel is not installed.
If UEK R2 is currently installed on an i386 system, the latest version of the UEK R2 kernel is installed.
If UEK R2 is currently installed on an x86-64 system and you upgrade using the Oracle Linux 6 Update 6 installation media for x86-64, which do not contain a UEK R2 repository, the latest version of UEK R2 is not installed.
If UEK R3 is currently installed on an x86-64 system, the latest version of the UEK R3 kernel is installed.
yum uses whatever repositories you have
configured on your system to upgrade it. You can find the latest
UEK R2 packages in the ol6_i386_UEK_latest
and ol6_x86_64_UEK_latest repositories and
the latest UEK R3 packages in the
ol6_UEKR3_latest repository.
If you want to install the latest UEK R2 kernel on an i386 or
x86-64 system, subscribe your system to the
ol6_i386_UEK_latest or
ol6_x86_64_UEK_latest channel on ULN, or
configure the repository in the
/etc/yum.repos.d/public-yum-ol6.repo file as
shown here:
[ol6_UEK_latest] name=Latest Unbreakable Enterprise Kernel for Oracle Linux $releasever ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEK/latest/$basearch/ gpgkey=http://public-yum.oracle.com/RPM-GPG-KEY-oracle-ol6 gpgcheck=1 enabled=1
If you want to update an x86-64 system to use the latest UEK R3
kernel, subscribe your system to the
ol6_x86_64_UEKR3_latest channel on ULN, or
configure the repositories in the
/etc/yum.repos.d/public-yum-ol6.repo file as
shown here:
[ol6_UEKR3_latest] name=Latest Unbreakable Enterprise Kernel Release 3 for Oracle Linux $releasever ($basearch) baseurl=http://public-yum.oracle.com/repo/OracleLinux/OL6/UEKR3/latest/$basearch/ gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-oracle gpgcheck=1 enabled=1
Once you have set up the ULN channels, Public Yum repositories, or installation media repositories that yum should use, you can update all installed packages by running the following command:
# yum updateThis command upgrades your system to Update 6.
You can use the following command to update a specific package:
# yum update package For example, to update the Z-shell package (zsh), you would enter:
# yum update zsh
For more information, see the yum(8) manual
page.
