- A new tunable parameter /proc/sys/vm/max_writeback_pages
has been added to the kernel, allowing system administrators to change

iteration each time it runs. It defaults to 1024 or 4MB so that a
maximum of 1024 pages get written out by each iteration of kupdate.

Unbreakable Linux Support
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
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'.
