Known Issues
1. pirut and system-config-packages cannot be used
to manage, install, and uninstall software packages. Follow the steps describe
below to resolve the issue
- Mount the DVD iso of the desired update of Oracle Enterprise Linux
Release 5.
Use the following command for mounting the DVD
media inserted in /dev/cdrom
# mount -r -o loop -t iso9660 /dev/cdrom
/mnt
Use following command to mount iso image
file
# mount -o loop <iso image file
name> /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
2. Following packages can not co-exists due to file conflict
- freeradius and freeradius2
- postgres and postgresql84
- samba and samba3x
3. If updating from OEL 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'.
Unbreakable Linux Support
Oracle Enterprise Linux offers
an option to keep your operating system up to date with latest operating system
patches using up2date. To be able to use
this option you need to have Unbreakable Linux Support. For more information
please visit http://linux.oracle.com
Note: Prior to using up2date, import
the RPM-GPG-KEY for Oracle Enterprise Linux:
rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY
