Re: DBAs running root.sh

Thanks for your response.

So, I think you are saying it's possible to configure sudo like this:

If I can only run myscript.sh as root and myscript.sh does "/bin/rm -fr /" , the script will fail because i don't have "/bin/rm" as root.

Have I got that right?

So, as long as your sudo setup is correct, there is nothing you can do in the root.sh script that can cause damage. Another way to look at it - if you have sudo access and there is something damaging you can do, you can do it without modifying the root.sh script. The dependency here is that sudo is setup correctly.

We'd need a root-owned root.sh for every distinct ORACLE_HOME path we create (some hosts have multiple homes, so there's dbhome_1, dbhome_2 etc.). Maybe there are other considerations that I'm unaware of - I don't really like to second guess what else is going on in the "closed box" of the OUI that could be host dependent.
