Errata updates for RHEL
For the 5.2 box, after the RHN registration, you can do (as root) a:

yum -y update

This will perform all the necessary updates and will essentially resolve
dependencies without intervention provided that your network connection
is fairly reliable and that you have enough space on /var, /usr to get
those updates (usually not a problem).

For the 4.1 box, judging from the number of updates you need, if I were
you, I would:

i)Backup everything up on portable drives (system partitions: /, /etc/
,/usr/ /var/ and other) and

ii)Download the latest media from your RHN subscription channel
(Software Download section)

iii)Re-install the OS from the new media.

iv)Keep the backup handy in case the box came with other apps that are
non RH specific and restore the non-standard bits and bobs.

Hi Experts,

I am new bie to Linux from Solaris. We have two servers which came to us as part of transition. I registered the machine using rhn_register ( one is 4.1nehant and the other 5.2 )
and when I clicked on the portal there are 100's for 5.2 and around 5000 for 4.1 ( Errata updates) available to be installed.

Is it a good advice to configure yum & up2date in this circumstances or I can keep selecting and click for install. Please advice.
