Hello,

I have a little experience with Red Hat. I have a question about rollback.

I have hunted high and low but am unable to find any guide or such on how to use the rpm rollback feature in up2date. Many talk about using it but none never explain how. Such as what is the command I type to use it?

What do i type at the prompt to invoke it?

I have Red Hat ES 4 running on 2 servers. There are a few updates i need to do and they involve httpd. We have live apps running on theses servers using the httpd, and i want to make certain that if any thing goes wrong after update I can rollback to previous rpm setup.

Can anyone point me in right direction?

I searched Red Hat site but no mention of how to use rollback.

Any help much appreciated.

i think to do rollbacks, you use up2date --undo. not sure, i've never done it. whenever updates go amok, i uninstall the rpms with --nodeps and then reinstall.

i do believe that in order for rollbacks to work, you must enable them in /etc/sysconfig/rhn/up2date. i.e. enableRollbacks=1.

Thanks for reply....

I was able to find out that the --undo commands is one of the commands you can issue if the job your are trying to reverse was the one you just did.

I did finally find somthing that does a descent job of explaining use of the rollback feature. It suprises me that there is not alot of mention about this nice feature. I remember how painful it could be to have to do all this yourself. With this feature can make it much easier.

Anyway if anyone else needs info on it here is link i found on linux journal for it. Enjoy
