thank you...

What does yum clean all do?

Also, when I do yum update, where do the patches go? where can I review in case any of them clashes with any of my app servers?

thx so much expert....

hi,

just 'because' and as a matter of good sysadmin
clean all...

to check first
get a list of packages that are going to be updated, enter:
# yum list updates

to verify wich of your app will need to be updated


to check everything else
# tail -f /var/log/messages
# tail -f /path/to/log/file


To view log of all updated package, enter:

tail -f /var/log/yum.log
less /var/log/yum.log
grep -i bind /var/log/yum.log
