For the latest updates please refer to the online version of these
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.

installed. To install this kernel, follow these steps:
1. Mount Oracle Linux 5.9 DVD
2. Copy the RPMs from mount_point/Server/oracle_updated to your system
3. Install required kernel using the rpm command, e.g.
# rpm -ihv kernel-2.6.18-308.0.0.0.1.el5.x86_64.rpm
Unbreakable Enterprise Kernel
Introduction
The Unbreakable Enterprise Kernel Release 2 is Oracle's second major
release of its heavily tested and optimized operating system kernel for
Oracle Linux 5 and Oracle Linux 6. It is based on the mainline Linux 3.0
version 3.0.36. It contains a large number of improvements and new
features that have been incorporated into mainline Linux since the first
version of the Unbreakable Enterprise Kernel. Please see the initial
Oracle Unbreakable Enterprise Kernel Release 2 Release Notes
<https://oss.oracle.com/ol6/docs/RELEASE-NOTES-UEK2-en.html> for a
detailed description of these changes.
The 2.6.39-300 release is a quarterly driver update release which also
includes bug and security fixes.
Note: the actual version number displayed by the kernel and on the RPM
packages is 2.6.39. This was done to avoid potential breakage of
certain low-level utilities of the Oracle Linux distribution (also known
as the "plumbing") that potentially can't cope with the new 3.x version
scheme. Regular Linux applications are usually not aware or affected by
Linux kernel version numbers.
Notable changes
* The code base has been aligned with mainline Linux 3.0.36
* Support for the SGI UV 2 architecture has been added
* Support for family 15H model 2 "Abu Dhabi" AMD processors has been added
* NBD, the network block device driver has been updated and enabled
(CONFIG_BLK_DEV_NBD=m)
Driver Updates
The Unbreakable Enterprise Kernel supports a wide range of hardware and
devices. In close cooperation with hardware and storage vendors, several
device drivers have been updated by Oracle.
Storage drivers
* Broadcom bnx2i 2.7.2.2
* Broadcom bnx2fc 1.0.11
* Emulex be2iscsi 4.4.58.0o

* Qlogic qla2xxx driver to 8.04.00.08.39.0-k
* VMware PVSCSI driver to 1.0.2.0-k
Network drivers
* Broadcom bnx2 2.2.3
* Broadcom bnx2x 1.72.50-0
* Broadcom cnic 2.5.12
* Broadcom tg3 3.124
* Cisco enic 2.1.1.39

* QLogic qlcnic 5.0.28.1
* Realtek 8139cp
* Realtek 8139too
* Realtek r8169 2.3LK-NAPI
Notable bug fixes
* The OCFS2 file system was updated to incorporate a large number of
bug fixes
* Xen: The BIOS SMP MP table search was disabled. This resolves a
crashing bug that was observed on HP Proliant BL680c G5 and DL380
G6 systems
* Fixed system UUID mismatch between dmidecode output and sysfs value
displayed in /sys/devices/virtual/dmi/id/product_uuid
* Fixed regression against UEKR1 (2.6.32): Don't warn on mlock ulimits
on shm_hugetlb
* MTRR: Fixed a type overflow in range_to_mtrr function, resulting in
"BADgran_size" errors on systems with lots of RAM
Technology Preview
Following features included in the Unbreakable Enterprise Kernel Release
2 are still under development, but are already made available for
testing/evaluation purposes.
* 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.
* Transcendent memory: Transcendent Memory (tmem for short) 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/
Compatibility
Oracle Linux maintains user-space compatibility with Red Hat Enterprise
Linux, which is independent of the kernel version running underneath the
operating system. Existing applications will continue to run unmodified
on Unbreakable Enterprise Kernel Release 2 and no re-certifications are
needed for RHEL certified applications.
The Oracle Linux team works closely with 3rd party hardware and software
vendors to minimize impact on interoperability during releases but in
order to introduce new drivers there are instances where changes must be
made. In this release, there are changes to the kernel ABI which
requires 3rd party kernel modules on the system be recompiled. Before
installing this update, please verify the support status of this release
with your application vendor(s).
Known issues
* Nouveau kernel driver is not compatible with NVIDIA graphics
driver: After upgrading to UEKR2, the NVIDIA driver upgrade script
doesn't properly blacklist the Nouveau kernel driver. To properly
blacklist the driver, append rdblacklist=nouveau nouveau.modeset=0
to the kernel boot parameters in /boot/grub/grub.conf.
* ACPI: One some systems you may see ACPI-related error messages in
dmesg similar to these:
ACPI Error: CDW1
</confluence/pages/createpage.action?spaceKey=OLPM&title=CDW1&linkCreation=true&fromPageId=7767826>
Namespace lookup failure, AE_NOT_FOUND
ACPI Error: Method parse/execution failed
ACPI Error: Field CDW3
</confluence/pages/createpage.action?spaceKey=OLPM&title=CDW3&linkCreation=true&fromPageId=7767826>
at 96 exceeds Buffer NULL
</confluence/pages/createpage.action?spaceKey=OLPM&title=NULL&linkCreation=true&fromPageId=7767826>
size 64 (bits)]]>
These are not fatal and are caused by bugs in the BIOS. Try
contacting your system vendor for a BIOS update. (Oracle BUG 13100702)
* ASM: calling the oracleasm init script /etc/init.d/oracleasm with
the parameter scandisks may lead to error messages about missing
devices similar to the following: oracleasm-read-label: Unable to
open device "/dev/xvdc1": No such file or directory However, the
device actually exists. This error message can be ignored, it is
triggered by a timing issue. The init script should only be used to
start and stop the oracleasm service, all other options like
scandisks or listdisk or createdisk are deprecated. For these and
other administrative tasks, use the regular binary in
/usr/sbin/oracleasm instead. (Oracle BUG 13639337)
* Btrfs: Running btrfs filesystem balance converts a non-RAID/concat
file system setup to RAID0 after adding a new device. (Oracle BUG
13715389)
* Btrfs: Converting an existing ext2/3/4 root file system to Btrfs
does not carry over the associated security contexts that are stored
as part of a file's extended attributes. With SELinux enabled and
set to enforcing mode, you may experience a lot of "permission
denied" errors after reboot, rendering the system unbootable. To
avoid this problem, make sure to enforce an automatic file system
relabeling run at bootup time. You can trigger this by creating an
empty file named autorelabel (e.g. by using touch) in the file
system's root directory before rebooting the system after the
initial conversion. This will instruct SELinux to recreate the
security attributes for all files on the file system. In case you
forgot to do this and rebooting fails, you can either temporarily
disable SELinux completely by adding selinux=0 to the kernel boot
parameters, or you can just disable the enforcing of the SELinux
policy by adding enforcing=0. (Oracle BUG 13806043)
* CPU microcode update failures on PVM/PVHVM guests: When running
Oracle Linux with the Unbreakable Enterprise Kernel Release 2, you
might see error messages in dmesg or /var/log/messages similar to
this one: microcode: CPU0 update to revision 0x6b failed. This
warning can be ignored, as the microcode for virtual CPUs as
presented to the guest does not need to be updated. (Oracle BUG
12576264 and 13782843)
* IO scheduler: The Unbreakable Enterprise Kernel uses the
'deadline' scheduler as the default IO scheduler. For the Red Hat
Compatible Kernel, the default IO scheduler is the 'cfq' scheduler.
* libfprint: The following message might appear in dmesg or
/var/log/messages: WARNING! power/level is deprecated; use
power/control instead. The USB subsystem in UEKR2 deprecated the
"power/level" sysfs attribute in favor of the "power/control"
attribute. The "libfprint" finger printing library would trigger
this warning via udev rules that try to use the old attribute first.
However, the setting of the appropriate power level still succeeds -
the warning can be safely ignored. (Oracle BUG 13523418)
* sched_yield() settings for CFS: For the Unbreakable Enterprise
Kernel, kernel.sched_compat_yield=1 is set by default. For the Red
Hat Compatible Kernel, kernel.sched_compat_yield=0 is used by default.
* Virtualization: When booting Unbreakable Enterprise Kernel Release
2 as a 32bit PVHVM guest, the following kernel message can be safely
ignored: register_vcpu_info failed: err=-38 (Oracle BUG 13713774)

Known Issues for Oracle Linux 5.9
1. Red Hat compatible Kernel with Oracle bug fixes will be updated to
standard Red Hat compatible kernel during ISO upgrade
The Oracle Linux ISO has the patched Red Hat compatible
kernel but it is not in the iso repodata, therefore if the ISO
is used to upgrade, the kernel will be updated to the Red Hat
compatible version of the latest release (the non-patched). This
is expected behavior.
2. Red Hat compatible Kernel will be updated to standard Red Hat
compatible kernel with Oracle bug fixes during ULN upgrade
If a 5.8 system running the Red Hat compatible kernel registers
to the 5.9 ULN channel, the kernel will be updated to the Red
Hat compatible with Oracle bug fixes version of the latest
release. This is expected behavior.
3. Error: "qemudStaretup:1728: Unable to create cgroup for driver: No
such device or address"
Use the following steps to workaround this error:
mkdir /dev/cgroup
mount -t cgroup none /dev/cgroup -o cpu, memory, devices
4. Differences in multipath -ll output between 5.7 UEK and Base Kernel
In some multipath failure cases, the mpath maps can get flushed
when all paths fail, and multipath -l displays no information on
the status of the multipath devices. This has been reported with
2.6.39 UEK kernels using NetApp LUNs, but not when running
2.6.18 series kernels with the same storage LUNs.
5. Unable to mount btrfs on Oracle Linux 5, error:
mount /dev/sda /mnt
mount: you must specify the filesystem type
To correct, add "-t btrfs" to the mount statement or add btrfs
in /etc/filesystems
6. On Oracle Linux 5, the "cp" command did not support reflinks on btrfs
Support for reflink was added to btrfs-prog and can be enabled
using "--reflink" as an option on "cp"
7. YUM command error occurs after system is removed from ULN
After removing a system from the list in ULN and running 'yum
update' on the server console, the following error is displayed:
AttributeError: 'module' object has no attribute 'RhnServerException'
To work around this issue remove /etc/sysconfig/rhn/systemid and
run 'yum update' again
8. dmsg error: "rtc_cmos: probe of rtc_cmos failed with error -16.
Error: Driver 'pcspkr' is already registered, aborting...kudzu[1373]
general protection ip:8056c78 sp:bfed96b0 error:0 in
kudzu[8048000+26000]"
This is a known issue that is seen with Oracle Linux 5 32-bit
para-virtualized guests created using virt-install"
9. UDEVD to be updated to use oom_score_adj to disable OOM on 2.6.39-UEK2
This change will set com_score_adj, if available otherwise if
this fails, it will fall back to the old com_adj
10. Installation completes successfully but grub.conf file is empty and
system will not successfully boot.
This occurs when trying to instal the bootloader to a cciss
device. To correct this, edit the drive order by moving
/dev/cciss/c0d0 ahead of /dev/sda
11. Missing openIB drivers (sdp/ulp) for Infiniband in UEK (R1/R2)
When attempting to load the openIB service the error "Loading
OpenIB kernel modules:FATAL: Module ib_sdp not found" is
displayed. This is an artifact of the ib_sdp driver from OpenIB
not being included in the UEK. If you are using OpenIB, you
should use the Red Hat compatible kernel.
12. Service TUX failed to start on Oracle Linux systems running the UEK
When attempting to start tux service (service tux start) the
system reports multiple errors for "No such file or directory"
and ends with "TUX not implemented in this kernel" TUX is not
shipped as part of the UEK and this is expected behavior.
13. After running yum update there are multiple errors in the
yumupdate.log indicating a failure to read modules kvm.ko,
kvm-amd.ko, ksm.ko, kvm-intel,ko with the message "no such file or
directory"
The error messages are generated due to bad symbolic links in the
Red Hat compatible kernel and are considered harmless.
14. HVM with PV Drivers Upgrade Issue: Cannot Update Bootloader
configuration
When upgrading a VM using the HVM with PV Drivers Domain type on
Oracle Enterprise Linux 5.9 from previous versions using the ISO
media, the option to upgrade the boot loader configuration may not
be available. This is due to a difference in the way the kernel
detects the disk devices that prevents it from detecting the
existing configuration. There are two ways to work around the problem:
- Use yum to upgrade the systems to 5.9 instead of an ISO
- Choose the "create new bootloader" option
After the upgrade, old kernel entries that refer to removed kernel
packages may remain in the grub.conf configuration file. Make sure
to boot to the 5.9 kernel and remove the invalid entries.
15. No networking after upgrading an Oracle Linux 5 HVM guest on Oracle
VM 2.2.2
Upgrading an existing Oracle Linux 5 Update 6 or Update 7 guest
which is running in HVM mode on Oracle VM 2.2.2 may result in
the network interface(s) being disabled after the reboot
post-upgrade. To resolve this issue, ensure that the network
interfaces are set to "paravirtual" in Oracle VM Manager.
Alternatively, to maintain the emulated devices inside the
guest, add xen_emul_unplug=never to the kernel boot line in
/boot/grub/grub.conf and reboot the guest.
16. No networking after upgrading an Oracle Linux 5 HVM with PV Drivers
guest on Oracle VM 2.2.2 or 3.0
Upgrading an existing Oracle Linux 5 Update 6 or Update 7 guest
which is running in HVM with PV Drivers mode on Oracle VM 2.2.2
or 3.0 may result in the network interface(s) being disabled
after the reboot post-upgrade. To resolve this issue, rename the
/etc/sysconfig/network-scripts/ifcfg-eth0.bak file to
/etc/sysconfig/network-scripts/ifcfg-eth0 and reboot the guest.
17. Warnings appear in dmesg on first boot
After an initial install of Oracle Linux 5.9, the following
warning may appear one or more times in the output of dmesg:
warning: process `firstboot' used the deprecated sysctl system call with 1.23.
This warning can be safely ignored.
18. New multipath settings requires changes to /etc/multipath.conf
Oracle Linux 5.9 includes a new version of
device-mapper-multipath. This new version requires manual
changes to the /etc/multipath.conf file. In the multipath.conf,
the line with *prio_callout* needs to be replaced by the keyword
*prio*, and a simple string, not an executable pathname, used
for the parameter to *prio*. Valid settings for *prio* are:
* alua
* ontap
* const
* random
* emc
* rdac
* hds
* tpg_pref
* hp_sw
* weighted
19. Multipath failure causes flush of all multipath devices
In some multipath failure cases, the multipath maps can get
flushed when all paths fail, and multipath -l displays no
information on the status of your multipath devices. This has
been reported with 2.6.39 UEK kernels using NetApp LUNs, but not
when running 2.6.18 series kernels with the same storage LUNs.
20. Error inserting cxgb3i module (13493043)
iscsi offload via cxgb3i on a server with Chelsio T3 Network
Controller will fail with following error if ofa kernel package
is installed
fatal: error inserting cxgb3i - unknown symbol t3_l2e_free
Use following workaround steps to fix the issue:
* Remove cxgb3i dependent module from memory if any loaded , i.e
# rmmod libcxgbi cxgb3
* Uninstall ofa package,
# rpm -e ofa-2.6.32-300.10.1.el6uek-1.5.1-4.0.47.x86_64
* Load cxgb3i module
# modprobe cxgb3i
21. Slow performance on 10Gb Ethernet Interfaces
The default networking tuning parameters may be too low for some
10Gb Ethernet interface drivers. If you are experiencing less than
expected network performance, change the following NIC parameters:
* rx-usecs: 1
* rx-frames: 0
To:
* rx-usecs: 10
* rx-frames: 10
22. dbus-daemon warning in dmesg on 32-bit systems
On 32-bit Oracle Linux systems, you may see the following
warning in dmesg:
warning: `dbus-daemon' uses 32-bit capabilities (legacy support in use)
This is only a warning and can be safely ignored.
23. iTCO_wdt warning in dmesg
Some server hardware may not support the Intel TCO watchdog
drivers. The following warning may be seen in dmesg:
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 disable this TCO WatchDog Timer Driver and suppress this
warning at boot time add the line "blacklist iTCO_wdt" to
/etc/modprobe.d/blacklist-watchdog".
24. Unbreakable Enterprise Kernel firmware must be manually installed
prior to upgrade
Due to a change in the way firmware is loaded between the Red
Hat Compatible Kernel and the Oracle Unbreakable Enterprise
Kernel, you may need to manually install the correct UEK kernel
firmware package if you want to boot a previous kernel version
after upgrading to Oracle Linux 5.9. For example, to install the
firmware for kernel-uek-2.6.39-300.10.1, download the correct
RPM package from the Unbreakable Linux Network and run the
following command:
# rpm -ivh --force kernel-uek-firmware-2.6.39-300.10.1.el5uek.noarch.rpm
25. Memory limited for Oracle Linux 5.9 Paravirtualized Guests
Oracle Linux 5.9 paravirtualized guests running on Oracle VM
with the Unbreakable Enterprise Kernel have a memory limit of
220GB. Setting the memory beyond this value may cause the
paravirtualized network interfaces to fail.
26. Oracle Linux 5.9 32-bit guest in HVM with PV Drivers mode with more
than 1 vCPU hangs on boot
Attempting to boot a 32-bit HVM guest with PV Drives with more
than 1 virtual CPU may fail. To resolve this issue, boot the
guest with a single virtual CPU and append *tsc=reliable
parameter to the kernel boot line in */boot/grub/grub/conf*. You
can then boot the guest with multiple virtual CPUs.
27. kexec/kdump may not work on some server platforms
Certain server platforms may not support the default kdump
parameters. To test this, enable kdump and issue:
echo c > /proc/sysrq-trigger
If your server hangs indefinitely, you may need to disable the
"reset_devices" parameter for kdump. To do this, edit
*/etc/sysconfig/kdump* and remove the "reset_devices" parameter
from the KDUMP_COMMANDLINE_APPEND variable.
28. 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 8 using yum
from ULN. Please use the following steps to upgrade:
# yum update yum
# yum update
29. Default kernel after upgrade
In certain upgrade scenarios the Unbreakable Enterprise Kernel
may not be the default boot kernel. Update /etc/grub.conf to
make the latest Unbreakable Enterprise Kernel as the default
boot kernel.
30. 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.
31. 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 occurred 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.
32. 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."
33. 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.
34. 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
35. 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-2.6.32-300.10.1.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
.
36. Setting serial console in a hardware virtualized (HVM) guest
To set the serial console a hardware virtualized (HVM) guest use
the 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
37. 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-2.6.32-300.10.1.el5uek.x86_64 ro root=/dev/sd0 nomodeset
38. Unable to start X (10056679)
On some hardware, startup of the 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.
39. Higher memory is required for crashkernel option
With the Unbreakable Enterprise Kernel a 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)
40. 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!
41. 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
42. Unable to remove directory during boot
The following message during boot can be ignored as SELinux does
not allow to recreate the login subdirectory and hence directory should
not be removed for dovecot:
Error :
"rm: cannot remove `/var/run/dovecot/login': Is a directory "
43. 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 manually after the upgrade.
44. 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-0.4.9-56.0.3.el5 and
kpartx-0.4.9-56.0.3.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-0.4.7-54.el5 and
device-mapper-multipath-0.4.7-54.el5) are also included on the
Oracle Linux 5.9 ISO in directory Server/oracle_updated.
45. 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
46. Conflicting packages
The following packages can not co-exists due to file conflict
* ant and ant17
* freeradius and freeradius2
* postgres and postgresql84
* samba and samba3x
* tcsh and tcsh617
* bind and bind97
* php and php53
* unixODBC and unixODBC64
* rsyslog and rsyslog5
47. 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
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'.
48. /ETC/MULTIPATH/WWIDS is missing after multipath-root install on OL5.9
When installing onto a multipath root disk, the file /etc/multipath/wwids is not automatically
generated at boot time, because the root disk (which is itself on multipath) is still in
read-only mode at the time multipath services start up. This will result in a warning message
displayed to the console at boot time:
Cannot open file [/etc/multipath/wwids] readonly: No such file or directory
This message is a warning that can be ignored safely; it does not affect the runtime operation
of multipathd or device-mapper-multipath. To squelch this warning message, after the system has
booted, it is possible to generate the missing wwids file with this command (executed as root):
multipath -l
A future errata update should include a complete fix for this issue.
Configuring Updates for Oracle Linux 5 Update 9
Unbreakable Linux Network
Oracle Linux offers an option to keep your operating system up to date
with latest operating system patches using up2date or yum.
To register with ULN, use the following command:
# up2date --register
To access Linux updates via Unbreakable Linux Network, you must purchase
a Linux support subscription. For more information please visit
http://linux.oracle.com <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 for the UEKR2
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.
Note: Prior to using up2date, import the RPM-GPG-KEY for Oracle Linux:
# rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY
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 5 Update 9 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 5 Update 9 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:
[ol5_base_media]
name=Oracle Linux 5 Update 9 Base Media
baseurl=file:///media/Server
gpgcheck=0
enabled=1
[ol5_uek_media]
name=Oracle Linux 5 Update 9 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.
