For the latest updates please refer to the online version of release
notes available at:
http://oss.oracle.com/el5/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.

Features
OpenFabrics Enterprise Distribution (OFED) 1.5.1
OFED implements Remote Direct Memory Access (RDMA) and kernel
bypass mechanisms to deliver high-efficiency computing,
wire-speed messaging, ultra-low microsecond latencies and fast
I/O for servers, block storage and file systems.
OCFS2 1.6
The Unbreakable Enterprise Kernel includes the OCFS2 1.6
kernel module. New features include:
o JBD2 support
o Extended attributes
o POSIX ACLs
o Security attributes
o Metadata checksums
o Indexed directories
o REFLINKs
For more details, see the OCFS2 1.6 User's Guide
<http://oss.oracle.com/projects/ocfs2/dist/documentation/v1.6/ocfs2-1_6-usersguide.pdf>
DIF/DIX support
The Linux data integrity framework (DIF) enables applications
or kernel subsystems to attach metadata to I/O operations,
allowing devices that support DIF to verify the integrity
before passing them further down the stack and physically
committing them to disk. Data Integrity Extensions or DIX is a
hardware feature that enables exchange of protection metadata
between host operating system and HBA.
Tickless kernel
The Unbreakable Enterprise Kernel is tickless. In the tickless
kernel, timer interrupts are performed on demand rather than
at a predetermined frequency. This allows CPUs to stay in a
low power state when the system is idle, reducing overall
power consumption
Task Control Groups (TCG)
TCG can track and group processes into user-defined cgroups so
that the operating system can treat them as whole and perform
scheduling, accounting, and resourceallocation accordingly.
For example, using TCG, you can associate a set of CPU cores
and memory nodes to a group of processes that makeup an
application or a group of applications. This enables
subsetting larger systems, more fine grained control over CPU
and memory, and isolation of applications.
Performance Counters for Linux (PCL)
The performance counter subsystem keeps track of hardware and
software events without affecting performance and enables you
to do tracing and performance analysis. Included is a tool
called perf for analysis.
SSD Detection
The kernel block layer will detect devices that claim to be
fast,solid state storage and tune itself accordingly. The
result of this detection can be found in:
/sys/block/xxx/queue/rotational
Where xxx is the block device. Echoing a 0 or a 1 into this
file will force the value to off or on. When assuming a device
is an SSD, the block layer will try harder to immediately
dispatch the IO to the device.
IO affinity
IO affinity ensures processing of a completed IO is handled by
the same CPU that initiated the IO. It can have a fairly large
impact on performance, especially on large NUMA machines. IO
affinity is turned on by default, but it can be controlled via
the tunable in /sys/block/xxx/queue/rq_affinity. For example,
the following will turn IO affinity on:
echo 1> /sys/block/sda/queue/rq_affinity
Receive packet steering (RPS)
RPS distributes the load of received packet processing across
multiple CPUs. This solution allows protocol processing (e.g.
IP and TCP) to be performed on packets in parallel. This
removes a bottleneck when a single core is saturated
processing network interrupts. To enable receive packet
steering for the interface xxx, place a CPU mask into
/sys/class/net/xxx/queues/rx-0/rps_cpus
The cpu mask takes the same form as the masks for the taskset
command. For example:
echo 0x55> /sys/class/net/eth0/queues/rx-0/rps_cpus
fallocate()
fallocate() is a new system call which will allow applications
to preallocate space to any file(s) in a file system.
Applications can get a guarantee of space for particular
file(s) - even if later the system becomes full. Using this
method of allocation can dramatically speed up the creation of
large files such as those used for virtual machine images.
Technology Preview Features
The following Technology Preview features are currently not supported
under Oracle Linux 5 and may not be functionally complete.
* Brocade BFA Fibre-Channel/FCoE driver
* FreeIPMI
* TrouSerS and tpm-tools
* eCryptfs
* Stateless Linux

These features are not suitable for production use. However, these
features are included to provide the feature with wider exposure.
Known Issues
1. Hardware virtualized (HVM) guests with Unbreakable Enterprise
Kernel always use paravirtualized (PV) drivers
Unbreakable Enterprise Kernel version
kernel-uek-2.6.32-100.34.1 adds support for paravirtualized
drivers in a HVM guest on Oracle VM. Starting with this kernel
version, 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-2.6.32-100.34.1.el5uek 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).
2. Using yum to upgrade previous update from Unbreakable Linux Network (ULN)
yum package need to be updated before upgrading previous update releases of Oracle Linux 5 to Oracle Linux 5 Update 7 using yum from ULN. Please use the following steps to upgrade:
# yum update yum
# yum update
3. Default kernel after upgrade
In certain upgrade scenerios after upgrade Unbreakable Enterprise Kernel may not be the default boot kernel. Update /etc/grub.conf to make latest Unbreakable Enterprise Kernel as the default boot kernel.
4. kernel-uek-headers on Unbreakable Linux Network (ULN)
Package kernel-uek-headers is available in "Enterprise Linux 5
Add ons (x86_64)" (el5_x86_64_addons) channel on ULN. To
install kernel-uek-headers subscribe to el5_x86_64_addons
channel and install kernel-uek-headers using following command
# up2date kernel-uek-headers
or
# yum install kernel-uek-headers
To replace kernel-uek-headers with kernel-headers
* make sure system is not subscribed to el5_x86_64_addons
channel
* remove package kernel-uek-headers using following command
rpm -ev --nodeps kernel-uek-headers
* Install kernel-headers package using following command
# up2date kernel-headers
or
# yum install kernel-headers
5. Missing kernel module ib_iser.ko
Starting OpenFabrics Enterprise Distribution 1.4.2-5 version
(ofa package), ib_iser kernel module is not built as part of
ofa package. If the ofa package installed on the system tries
to load ib_iser.ko, the following message will be displayed on
the console
ib_iser: disagrees about version of symbol ib_fmr_pool_unmap
ib_iser: Unknown symbol ib_fmr_pool_unmap
These messages can be ignored as ib_iser.ko is no more needed.
6. Upgrade failure for the full install of Oracle Linux 5
If any of the following packages are installed on the system
kmod-cmirror
kmod-cmirror-xen
kmod-gfs
kmod-gfs-xen
kmod-gnbd
kmod-gnbd-xen
Upgrade of Oracle Linux 5 system may fail with the following
error
An error occured while installing packages.
Please examine /root/install.log on your
installed system for detailed information
to workaround this problem, remove above packages before
upgrade. These packages can be installed after the upgrade.
7. Failed to stat /dev/mapper/* message during boot of
paravirtualized guests
Following messages during boot of paravirtualized guest can be
ignored
Failed to stat /dev/mapper/no
Failed to stat /dev/mapper/block
Failed to stat /dev/mapper/devices
Failed to stat /dev/mapper/found
These errors are expected as dmraid utility returns 'no block
devices found' because an ioctl to get serial numbers on pv
devices returns -EINVAL."
8. Incorrect user/sys time in kernel-uek (11651839)
Time utility might return incorrect system/user times in
Oracle Linux guest running Unbreakable Linux Kernel. This
issue is tracked by Oracle Bug 11651839.
9. 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.
10. 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 using the Red Hat
Compatible Kernel), use the following mount options:
-o vers=3,mountproto=tcp
11. Serial console not working for a paravirtualized guest ( 10059184)
Please use the following steps to configure the serial console
in a paravirtualized guest (PV) using the Unbreakable
Enterprise kernel (updates are in the guest):
1. change the kernel boot parameter 'console=xvc0' to
'console=hvc0' in the /etc/grub.conf:
kernel /vmlinuz-2.6.32-100.0.19.el5 ro root=/dev/sd0 console=tty0 console=hvc0
2. add an 'hvc0' entry to /etc/inittab:
co:2345:respawn:/sbin/agetty hvc0 9600 vt100-nav
3. add an 'hvc0' entry to /etc/securetty
.
12. 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
* add the following to /etc/inittab
co:2345:respawn:/sbin/agetty ttyS0 57600 vt100-nav
13. 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-2.6.32-200.11.1.el5uek.x86_64 ro root=/dev/sd0 nomodeset
14. Unable to start X (10056679)
On some hardware startup of X environment may fail after
upgrading to Unbreakable Enterprise Kernel with following Error:
Fatal server error:
Cannot run in framebuffer mode. Please specify busIDs for all
framebuffer devices.
To workaround this issue reconfigure X using command "X
-configure" and use generated configuration file to start X
environment.
15. Higher memory is required for crashkernel option
With Unbreakable Enterprise Kernel higher memory setting is
required for crashkernel option in /etc/grub.conf file.
Booting with crashkernel=128M@16M will result in following error:
crashkernel reservation failed - memory is in use
Minimum value for crashkernel option is 128M@32M. Based on the
system configuration a higher value may be required. If kdump
service loading fails increase the second value (32M). If the
system hangs or crashes with out of memory during dumping core
increase the first value (128M)
16. 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.
17. 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.
18. High IO loads on NFS using mmap may fail (11071875)
In some instances, large IO loads on NFS that use mmap may
fail and cause the kernel to panic with a message like:
kernel BUG at mm/truncate.c:469!
19. NFS: Error message displayed while mounting an NFS filesystem
(10070721)
The following error may be encountered while mounting an NFS
filesystem:
"SVC: FAILED TO REGISTER LOCKDV1 RPC SERVICE (ERRNO 97)."
This is an informative message and can be ignored
20. Warning message when kdump starts
When kdump starts, you may see the following warning message:
WARNING: No modules scsi_mod found for kernel 2.6.32-200.11.1.el5uek.x86_64, continuing anyway
This warning can be ignored. The kdump service does get
started and a vmcore does get generated.
21. Unable to remove direcory during boot
Following message during boot can be ignored as selinux does
not allow to recreate login subdir and hence directory should
not be removed for dovecot:
Error :
"rm: cannot remove `/var/run/dovecot/login': Is a directory "
22. Warning during kernel install
Following warnings during kernel install can be ignored:
WARNING: No module ehci-hcd found for kernel 2.6.32-200.10.3.el5uek, continuing anyway
WARNING: No module ohci-hcd found for kernel 2.6.32-200.10.3.el5uek, continuing anyway
WARNING: No module uhci-hcd found for kernel 2.6.32-200.10.3.el5uek, continuing anyway
23. Upgrade ocfs2 and oracleasm kernel modules
ocfs2 and oracleasm kernel modules will not be automatically
updated during upgrade of Oracle Linux 5 as package name for
these modules contains kernel version in it. These packages
need to be updated manulaly after the upgrade.
24. device-mapper-multipath package for Red Hat compatible kernel
Unbreakable Enterprise Kernel requires kpartx and device-mapper-multipath
RPMs that are newer than those provided for the Red Hat compatible
kernel. By default device-mapper-multipath-0.4.9-23.0.9.el5 and
kpartx-0.4.9-23.0.9.el5 are installed. These updated versions of kpartx
and device-mapper-multipath are supported with the Red Hat compatible
kernel. The original RPMs for the Red Hat compatible kernel
(kpartx-0.4.7-46.el5 and device-mapper-multipath-0.4.7-46.el5) are also
included on the Oracle Linux 5.7 ISO in directory Server/oracle_updated.
The instructions for installing the versions of kpartx and
device-mapper-multipath to go with the Red Hat compatible
kernel via ULN are as follows:
* Get the Red Hat compatible version of
device-mapper-multipath package
1. From Oracle Linux ISO image
o Mount Oracle Linux 5.7 DVD
o Copy the rpms from
mount_point/Server/oracle_updated to your system
2. From ULN
o Make sure you are subscribed to the Oracle
Linux 5 Latest channel or at least the
Oracle Linux 5 Update 7 Patch channel on ULN
o Download the RPMs using the following command:
# up2date --get kpartx-0.4.7-46.el5 device-mapper-multipath-0.4.7-46.el5
RPMs will be downloaded to
/var/spool/up2date.If you are using yum and
the yum-rhn-plugin, you can use the
yumdownloader tool instead of up2date:
# yumdownloader kpartx-0.4.7-46.el5 device-mapper-multipath-0.4.7-46.el5
The yumdownloader tool is part of the
yum-utils package and may need to be
installed seperately. If you use this
method, the RPMs will be downloaded into
your current directory.
* Boot the system with RHAT compatible kernel.
* Flush out the DM multipath devices
# multipath -F
* Stop the multipath deamon
# service multipathd stop
Stopping multipathd daemon: [ OK ]
* Install/downgrade the kpartx and device-mapper-multipath
rpms
# rpm -Uvh --force --nodeps kpartx-0.4.7-46.el5.x86_64.rpm device-mapper-multipath-0.4.7-46.el5.x86_64.rpm

# rpm -e device-mapper-multipath-libs
* Restart the multipath deamon
# service multipathd start
Starting multipathd daemon: [ OK ]
* Run the multipath -ll command to lists all the multipath
devices
* Ensure that device-mapper-multipath and kpartx are not
automatically updated with newer versions by adding the
following to the pkgSkipList entry in
/etc/sysconfig/rhn/up2date
device-mapper-multipath*;kpartx*;mkintrd*;
25. Workaround to use pirut and system-config-packages to manage
packages
Pirut and system-config-packages cannot be used to manage,
install, and uninstall software packages. Follow the steps
below to resolve the issue
* Mount the DVD iso of the desired update of Oracle Linux
Release 5.
Command for mounting the DVD media inserted in /dev/cdrom
# mount -r -o loop -t iso9660 /dev/cdrom /mnt
Command to mount iso image file
# mount -o loop /mnt
* Create yum repository configuration file
/etc/yum.repos.d/dvd.repo with following contents
[dvd]
name=OEL5DVD
baseurl=file:///mnt/Server
enabled=1
gpgcheck=1
gpgkey=file:///mnt/RPM-GPG-KEY file:///mnt/RPM-GPG-KEY-oracle
* Clear and update the yum cache
# yum clean all
# yum update
* Run pirut/system-config-packages to manage software
packages
26. Conflicting packages
Following packages can not co-exists due to file conflict
* freeradius and freeradius2
* postgres and postgresql84
* samba and samba3x
* tcsh and tcsh617
* bind and bind97
* php and php53
27. Unresolved dependency during update using up2date
If updating from Oracle Linux 5 GA or RHEL 5 GA using up2date,
you may encounter the following error:
Unresolvable chain of dependencies:
xen-3.0.3-64.el5 requires xen-hypervisor-abi = 3.1
This happens because a kernel-xen package update is needed by
the xen package, but 'kernel*' is part of the up2date
pkgSkipList. To get around this, add 'xen;xen-devel;' to the
the pkgSkipList line in /etc/sysconfig/rhn/up2date and then
run up2date. You can update the xen and kernel-xen packages
together later via 'up2date --force xen kernel-xen'.
