Urgent Help needed: Want to restore the ownership of root partition

[mallinath]

Dear Friends:

I am in process of installing Oracle software over RedHat Linux Enterprise 2.1 server.
OS was installed 2 weeks back and is not backed up.

During the process of changing the ownership of the copied media (CDS) from root:others to oracle:dba , mistakenly typed
cd /usr01
chown -R oracle:dba ..
This resulted in changing the file ownership to oracle:dba of all the directories and files under root.

later I changed back to root:root executing
chown -R root:root

Now I require help in restoring back the ownership since some services are not getting started.

can anybody sujest me some way by which I can restore back.

Just incase anybody has the same Linux server version . I guess following command below will provide me the list of file ownership.
cd /
ls -lR initrd misc boot var usr bin opt sbin lib etc dev root|grep -v
total|grep -v ":$"|awk -F' ' '{ if ( $3 != 'root' || $4 != 'root' )
print ; }' > File_perm.txt

Thanking in anticipation

I am not sure why, since you were not in the / directory.

As for restoring all files on your system to their original owners and groups, I do not know of a way. Hopefully you have some backups you can refer to.
