The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
ULN provides an
ol
repository, which includes all packages for an Oracle Linux
release. It also provides N
_arch
_latestbase
and
patch
channels for each update of an Oracle
Linux release. Depending on the Oracle Linux release, other
channels might provide the latest packages for additional features
such as DTrace user-space, Ksplice, and OFED.
The Oracle Linux yum server provides a
public_ol
repository, which includes all packages for an entire Oracle Linux
release in addition to a
N
_latestpublic_ol
repository for each update. Unlike ULN, the Oracle Linux yum
server does not provide N
_un
_basepatch
channels for
updates.
Some channels, such as those for Spacewalk Client and Spacewalk Server, are available on the Oracle Linux yum server but not on ULN. Other channels, such as those for DTrace user-space, Ksplice, and OFED packages, are available on ULN but not on the Oracle linux yum server.
Oracle recommends that you design a channel configuration that is
based on your own work flow. For example, if you intend to use
Spacewalk's channel cloning feature to promote systems from
development through testing to production, you could configure a
base
channel and child patch
channel together with other child channels.
Avoid cloning latest
channels as this takes a
long time given that these channels are usually very large. If you
duplicate child channels, you do not need to duplicate their
repositories. These channels can use the same repositories as the
channel from which they were cloned. For example, each cloned base
channel might have a unique addons
child
channel, but each of these child channels would use the same
repository. The packages are not duplicated, even though they are
referenced in multiple channels.
If necessary, you can maintain the latest
channels separately without subscribing any systems to these
channels. If the need arises, you can copy errata packages form
the latest
channels to the
patch
channels to make the latest fixes
available.
