Linux command about ownership

Hi!

I have question about linux command.
Let assume I have a two user on the linux server hosted .
#sudo su -
#sudo su - oracle

The linux server is having the command ./opmnctl restart command to restart a opmn process on the server.

./opmnctl command having ownership as oracle.oracle

If you logged in as root user by sudo su - ,
and did a restart of opmnctl restart .

Can it is possible that it can change a ownership of all files to root.root?
Is it logical /possible by any means?

Thanks in advance!!!

logically root has right to do anything on the host, so root can change ownership. But also logically a restart command will not modify ownership.

Yes.I agree with you.

But since , root has not changed the permission on its own.

What is the chance that it might affect the file system along with changing ownership?

Is there any chance that it is written in the script of restart that no other can run.But since
root can perform it , it allows root and damages the filesystem and changes ownership?

I am logging to these servers through putty and hosted in other country through private network.
Since after restart , permission get changed (it's not confirm that it gets changed by same action) ,
no other user than root can restart it.

What I can imagine is: the script will check ownerships (or ???) and will try to restore some default values. I do not think it is a good idea but it can happen.
