For the latest updates please refer to the online version of release notes
available at:
http://oss.oracle.com/ol6/docs/
NOTE: An upgrade of Oracle Linux from a beta release is not supported.
Further, an in-place upgrade between major versions of Oracle Linux is not
supported. Oracle does not recommend an upgrade from earlier major
versions of Oracle Linux even though anaconda provides an option to do
this upgrade. A fresh installation is strongly recommended rather than a
system upgrade between major versions.
Customers who want to use new features in Unbreakable Enterprise Kernel
can do so without upgrading to Oracle Linux 6 as Oracle Linux 5.8 already
includes Unbreakable Enterprise Kernel.

Kernel
Oracle Linux 6 Update 3 ships with two sets of kernel packages:
* Unbreakable Enterprise Kernel Release 2
[kernel-uek-2.6.39-200.24.1.el6uek]
* Installed and booted by default
* Red Hat compatible Kernel [kernel-2.6.32-279.el6]
* Installed by default
Note: 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 by
default. If needed, /etc/grub.conf and /etc/sysconfig/kernel can be
modified to make the system boot with the Red Hat Compatible Kernel by
default.

Features
This release of the Unbreakable Enterprise Kernel has been
improved/enhanced by Oracle in several areas, including bug fixes and
extended functionality. All of these modifications have been contributed
back upstream and are available in mainline Linux.
Btrfs
Btrfs provides a flexible way to manage storage, without needing a
separate volume manager. It provides built-in RAID support and ensures
data integrity by using redundancy and checksums. Btrfs also supports
lightweight copies/clones of files or directories with snapshots as well
as online data compression. The Btrfs code in the Unbreakable Enterprise
Kernel Release 2 includes many new features as well as numerous
performance improvements, that were merged from a number of long running
projects and cleanup queues.
Note: The standard installation media does not have support for creating a
btrfs root filesystem on initial install. If you want to install Oracle
Linux 6 Update 3 and use btrfs as your root filesystem, please use the
alternative boot ISO media which uses btrfs as the default root
filesystem. Using the boot.iso requires that the full installation source
be available via a network method, i.e. FTP, HTTP or NFS.
New Btrfs features/functionality
* An updated version of btrfsfsck, a tool to check and repair a Btrfs
file system, is now included in the btrfs-progs package. This new
btrfsck now supports a --repair option that allows fixing errors in
the extent allocation tree and block group accounting. btrfsck also
provides the option --init-csum-tree which replaces the check-sum root
with an empty one. This will clear out the CRCs but allows the
file-system to be mounted with the mount option nodatasum.
* Automatic defragmentation: Brtfs now provides an online
defragmentation facility that reorganizes data into contiguous chunks
wherever possible to create larger sections of available disk space
and improve read and write performance.
* Scrubbing: you can initiate a check of the entire file system by
triggering a file system scrub job that is performed in the
background. The scrub run scans the entire file system for integrity
and automatically attempts to report and repair any bad blocks it
finds along the way. Instead of going through the entire disk drive,
the scrub run only deals with data that is actually allocated.
Depending on the allocated disk space, this is much faster than
performing an entire surface scan of the disk.
* LZO compression: In addition to the already existing zlib compression
algorithm, data can now be alternatively compressed using LZO, which
provides higher compression ratios and faster decompression for
certain types of data.
* Read-only snapshots
* Different compression and copy-on-write settings for each
file/directory (in addition to the per-filesystem controls). Btrfs
compression can be controlled on a per file/directory basis. It can be
enabled any time after a subvolume has been created. In the default
mode, it will flag the file as not compressible and will not try to
compress blocks again. In compress-force mode, Btrfs will keep trying
for new writes, in case the newly added file content becomes
compressable.
* List all subvolumes on a file system (btrfs subvolume list)
* List all files recently modified (btrfs subvolume find-new)
* Allow changing the subvolume to be mounted by default with
btrfs subvolume set-default (to better support snapshot-assisted
distribution upgrades)
* Direct I/O support
* Introduced mount option nospace_cache
* Allow to mount -o subvol=path/to/subvol/you/want relative from the
normal fs_tree root
* Now records a number of previous tree roots as backups, which can be
useful in recovering damaged filesystems. If a given mount fails to go
through because a tree root is bad, you can now use mount -o recovery
and Btrfs will walk through the array and try to mount older versions
of the file system.
Btrfs bug fixes and performance improvements
* Asynchronous creation of snapshots. Avoids waiting for the snapshot to
be committed to disk.
* Significantly improved ls readdir() performance
* Switched the btrfs tree locks to reader/writer
* Improvements to the logging code. Lots of data was logged more than
once, greatly increasing the I/O load. Log I/O traffic has been cut to
~25% of the previous level.
* Allow to overcommit ENOSPC reservations (speeds up a test from 45
minutes to 10 seconds)
* Be smarter about committing the transaction: xfstests 83 goes from
taking 445 seconds to taking 28 seconds
* Inode Items operation improves file creation and deletion performance
significantly
* Improved reserved space accounting and handling -ENOSPC (out of disk
space) situations
* Dump free space cache on disk to speed up block group caching
* Fixed regressions in the mount and general error handling code, which
also fixes some problems in the mount -o autodefrag mode
* Tweaked the ENOSPC throttling. The file system tries to start I/O to
make sure it can do all the allocations that it has promised to do.
The end result is a dramatic improvement in random write workloads
among many others.
* Improved the scrubber and provided utilities to walk Btrfs' many
backrefs. The scrubber is much faster thanks to extensive btree
readahead and instead of just informing the user that a specific block
is bad, it tells him which btree or which file was impacted by that
bad block.
* Fixed the Btrfs cache flushing. This one probably explains many of the
corruptions that have been reported, especially on multi-device
filesystems. Ceph users running with -o notreelog were dramatically
more likely to trigger the corruptions. The problem was that Btrfs was
triggering cache flushes before the last copy of the super block,
instead of doing them before the first copy. Take extra care about
getting flushes done to all the devices in a multi-device FS before
writing any of the supers.
* Fix for tree corruptions when running multi-threaded snapshots with
mount -o inode_cache enabled
Xen domU improvements
Several bug fixes and improvements have been incorporated to make the
Unbreakable Enterprise Kernel scale and cooperate better as a guest (domU)
in Oracle VM and Xen.
* Xen block backend from Linux 3.3 kernel. This provides the fully
featured Xen blkback along with extra features, such as passing
through a flush (a lighter version of barrier), discard (also known as
TRIM or SCSI UNMAP) and various bug-fixes and enhancments.
* Xen PCI backend from Linux 3.3 kernel, this includes the option to
specify how the PCI structure shows up in the PV guest - either as in
host or virtualized; Fixes to make it work with SR-IOV VF cards; and
numerous mutex fixes.
* Memory self-ballooning - allows the guest to automatically balloon
depending on the workload.
* Transcendent memory support for HVM and PV guests
* Tracing API support for Xen MMU operations.
* Syncing the wall-clock time from the initial domain
* Numerous code cleanups and bug fixes (e.g. in the following areas:
memory balloning, blkfront, P2M, E820, IRQ, MMU, Gntalloc driver)
Other improvements
* dm-nfs: device-mapper target that allows you to treat an NFS file as a
block device. It provides loopback-style emulation of a block device
using a regular file as backing storage. The backing file resides on a
remote system and is accessed via the NFS protocol.
Upgrading to Oracle Linux 6 Update 3
As Oracle Linux 6 Update 3 now ships with the latest Unbreakable
Enterprise Kernel Release 2, upgrading via the installation media will
evaluate whether or not to install this latest kernel based on the
currently installed kernel.
The following upgrade scenarios should be considered:
1. Upgrading from Oracle Linux 6 GA, Update 1 or Update 2 without UEK2
installed
If you have an existing Oracle Linux 6 GA, Update 1 or Update 2
install that does not have the already released Unbreakable
Enterprise Kernel Release 2 installed, the Oracle Linux 6 Update 3
media will not install this kernel by default. Note that the Oracle
Linux 6 Update 3 installation media does not contain any updates to
the original Unbreakable Enterprise Kernel, so in this scenario,
only the latest Red Hat Compatible Kernel will be installed.
2. Upgrading from Oracle Linux 6 GA, Update 1 or Update 2 with the UEK2
installed
If you have an existing Oracle Linux 6 GA, Update 1 or Update 2
install that already has the released Unbreakable Enterprise Kernel
Release 2 installed, the Oracle Linux 6 Update 3 media will install
the latest version of this kernel.
Upgrades that are performed via YUM will use whatever repositories are
configured to upgrade the system. The latest Unbreakable Enterprise Kernel
Release 2 can be found in the ol6_<arch>_UEK_latest repository, i.e.
either ol6_i386_UEK_latest or ol6_x86_64_UEK_latest. You should ensure
that this repository is enabled either via the Unbreakable Linux Network
or in the /etc/yum.repos.d/public-yum-ol6.repo file if you want to install
this kernel.
Known Issues
1. Hardware virtualized with Paravirtualized Drivers (PVHVM) guests on
Oracle VM 3.0 crash during Oracle Database install
This can occur on Oracle VM 3.0 if the guest is set with a maximum
memory (maxmem) parameter greater than the amount set at boot
(memory). To avoid this issue, please ensure the maxmem and memory
parameters are equal. This issue has been resolved in Oracle VM
3.1.1.
2. Post-install Anaconda Errors
In certain cases, after successfully completing installation and
rebooting the system, it is possible that the following error stack
appears:
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
Or:
14:05:55 CRITICAL: anaconda 11.5.0.47 exception report
Traceback (most recent call first):
File "/usr/lib64/python2.6/site-packages/gtk-2.0/gtk/_lazyutils.py", line 32,
in __
getattr__
File "/usr/lib/anaconda/gui.py", line 1453, in keyRelease
if ((event.keyval == gtk.keysyms.KP_Delete
ImportError: No module named keysyms
These errors would also be logged in anaconda.log in /root after
installation. These errors can safely be ignored.
3. Cannot start FCoE Target service with Unbreakable Enterprise Kernel
The upstream release has added support for FCoE target service. This
is not supported with the previous release of the Unbreakable
Enterprise Kernel (2.6.32). Customers wishing to use this service
must boot into the Unbreakable Enterprise Kernel Release 2 (2.6.39)
or the Red Hat Compatible Kernel.
4. Cannot start CGroups Config service with Unbreakable Enterprise Kernel
This service is not supported with the previous release of the
Unbreakable Enterprise Kernel (2.6.32). Customers wishing to use
this service must boot into the Unbreakable Enterprise Kernel
Release 2 (2.6.39) or the Red Hat Compatible Kernel.
5. mlx4_core conflicts between mlnx_en and ofa packages
Both the new mlnx_en and ofa packages contain mlx4_core. Only one of
the two packages should be installed. Attempts to install both
packages on a single server will result in a package conflict error.
To determine which package to use, if you have a Mellanox Ethernet
Controller, please use mlnx_en. If you have a Mellanox Infiniband
Controller, please use ofa. If you have both, please use ofa as it
supports both Ethernet and Infiniband controllers.
6. kdump service fails to start with Unbreakable Enterprise Kernel
When configuring the crash kernel for the UEK, only standard crash
kernel settings, e.g. crashkernel=128M@32M, are supported. The new
setting used by the RHCK, i.e. crashkernel=auto, is not supported
and will cause the kdump service to fail to start.
7. "iTCO_wdt: failed to reset NO_REBOOT flag, device disabled by
hardware/BIOS" error in dmesg when running the Unbreakable Enterprise
Kernel Release 2
To get rid of this error at boot time, add the line "blacklist
iTCO_wdt" to /etc/modprobe.d/blacklist-watchdog
8. "iTCO_wdt: failed to reset NO_REBOOT flag, reboot disabled by
hardware" error in dmesg when running the Unbreakable Enterprise
Kernel
To get rid of this error at boot time, add the line "blacklist
iTCO_wdt" to /etc/modprobe.d/blacklist-watchdog
9. Hardware virtualized (HVM) guests with Unbreakable Enterprise Kernel
always use paravirtualized (PV) drivers
The Unbreakable Enterprise Kernel adds support for paravirtualized
drivers in a HVM guest on Oracle VM. The default is to present only
paravirtualized drivers when running in a hardware virtualized
guest. To run kernel-uek --including the drivers-- fully hardware
virtualized, an additional kernel boot parameter
"xen_emul_unplug=never" must be added to the boot parameters in
/etc/grub.conf:
kernel /vmlinuz-2.6.32-300.2.1.el6uek ro root=/dev/VolGroup00/LogVol00 xen_emul_unplug=never
Adding this kernel boot parameter makes the kernel also present the
emulated drivers as it did before (e.g. the 8139cp network driver).
10. Incorrect package count (11684244)
Selecting all packages in certain groups during installation might
not show the correct count.
11. Default reverse path filtering mode affects certain Oracle products
(10649976)
Oracle Linux 6 defaults to strict reverse path filtering. Some
Oracle products and network storage devices work more reliably when
using loose reverse path filtering. To enable loose mode reverse
path filtering, issue the following command (assuming you are
changing settings for the network interface called eth1). The
default setting is 1.
sysctl net.ipv4.conf.eth1.rp_filter=2
12. Receive Packet Steering errors for certain network operations
(11071685)
Certain network operations that utilize receive packet steering
could cause errors on the system.
13. Spurious udev messages during restore of a failed path (11682171)
When failed paths are restored in a multipath configuration, you may
see udevd-work error messages in /var/log/messages. The failed paths
do get restored despite these messages.
14. Default NFS v4 mount options
The default NFS mount option has changed to NFS v4. To mount an NFS
volume using NFS v3 (the default in Oracle Linux 5), use the
following mount options:
-o vers=3,mountproto=tcp
15. Setting serial console in a hardware virtualized (HVM) guest
To set the serial console a hardware virtualized (HVM) guest use
following settings in the guest:
* On the kernel boot line in grub.conf, add:
console=tty0 console=ttyS0,57600n8
* add the following to /etc/securetty
ttyS0
16. Oracle RDBMS Server 11gR2 Preinstall Settings not visible after
installation
If, during installation on an x86_64 system, the pam.i386 package is
installed either manually or via package dependency, and the
oracle-rdbms-server-11gR2-preinstall package is also selected, the
Oracle Database related settings in /etc/security/limits.conf will
be overwritten by the installation of the pam.i386 package. This is
most likely to occur when using a kickstart-based automated
installation that includes non-standard package selections. To
restore these settings, run the
oracle-rdbms-server-11gR2-preinstall-verify script.
17. Unbreakable Linux Network
After an install of Oracle Linux 6, the screens after the first
reboot will guide you to register your system to the Unbreakable
Linux Network (ULN). If you did not configure your network during
the initial installation, the registration process to ULN will not
succeed. In this case, you should configure your network by running
NetworkManager first (as root). Then restart the ULN registration by
running uln_register (as root).
18. Console appears to hang while booting on certain systems (10094052)
On some hardware, the console may appear to hang during the boot
process after starting udev. But the system does boot up properly
and is accessible. A workaround to this problem is to add nomodeset
as a kernel boot parameter in /etc/grub.conf:
kernel /vmlinuz-2.6.32-300.2.1.el6uek.x86_64 ro root=/dev/sd0 nomodeset
19. Default IO scheduler
For the Unbreakable Enterprise Kernel, the default IO scheduler is
the 'deadline' scheduler.
For the Red Hat Compatible Kernel, the default IO scheduler is the
'cfq' scheduler.
20. sched_yield() settings for CFS
For the Unbreakable Enterprise Kernel, kernel.sched_compat_yield=1
by default.
For the Red Hat Compatible Kernel, kernel.sched_compat_yield=0 by
default.

Configuring Updates for Oracle Linux 6 Update 3
Oracle Linux 6 no longer contains up2date for access to Unbreakable Linux
Network. Instead packages are managed using Yum. To register with ULN, use
the following command:
# uln_register
Unbreakable Linux Network
To access Linux updates via Unbreakable Linux Network, you must purchase a
Linux support subscription. For more information please visit
http://linux.oracle.com.
During ULN registration the server will be automatically registered with
two channels: the latest channel for the base repository as well as the
latest channel for the Unbreakable Enterprise Kernel Release 2. If you
have upgraded from a previous release and do not wish the UEK Release 2 to
be installed, you will need to manually unsubscribe the server from this
channel.
The Unbreakable Linux Network includes Oracle-specific software packages,
for example Oracle's ASMlib userspace package and the Oracle Instant
Client. To enable access to these packages, login to the Unbreakable Linux
Network and subscribe to the "Oracle Software" channel.
Public Yum
Oracle now provides all errata and updates for Oracle Linux via the public
yum service. This service does not require a Linux support subscription,
but only includes updates to the base distribution and does not include
Oracle-specific software. To enable updates via public-yum, please visit
http://public-yum.oracle.com and follow the instructions on that website.
By default, all new installs of Oracle Linux 6 Update 3 are automatically
configured to use the public-yum update service. No modification is
required to use this service. The public-yum service is automatically
disabled when a server is registered with the Unbreakable Linux Network.
Installation Media
Note: Oracle Linux 6 Update 3 now contains two distinct repository sources
on the installation media. To configure yum to use the installation media
as a yum source, create the following file /etc/yum.repos.d/Media.repo
with content similar to the following:
[ol6_base_media]
name=Oracle Linux 6 Update 3 Base Media
baseurl=file:///media/Server
gpgcheck=0
enabled=1
[ol6_uek_media]
name=Oracle Linux 6 Update 3 UEK Media
baseurl=file:///media/UEK2
gpgcheck=0
enabled=1
You may need to adjust the baseurl parameter to match where you mount the
ISO media on your server.
