Hi,

Can anyone tell me how about patch installation on linux?

How can we achieve the same?

Is it in the form of rpms?

how the latest fix will be supported by Redhat?

You don't.


By updating.


Yes.


By incorporating the latest fix in their next release of the package.


I suggest you read the admin docs that come with RHEL or on their site to get you up to speed on the basics.

To install software updates on RHEL, use the "up2date" command as root. This assumes that you have an active subscription with Red Hat; otherwise, you first will have to register your system with Red Hat. The actual download and installation of updates is about as automatic as you'll find anywhere. I believe that kernel updates are deselected by default since those updates usually recommend a reboot and rebooting is considered disruptive by the user community. If you want to include updates to the kernel, you'll have to select them in the up2date GUI. The up2date command also includes a "dry run" option which does everything except for downloading and installing the updates. You'll know exactly what changes will be made to your system before actually doing the update. To use this option, simply enter:

up2date --dry-run

Good luck!
