Friends,
We have Linux AS 3.0 as an OS in that Oracle 9i as a database server.
Now we are planning to change the linux's root password,linux's oracle user password,oracle 9i's system password.
my questions are....
1. if i change the root password for linux, will it affects oracle 9i in any way? and vice-versa
2. if i change the system password in oracle 9i what are all the precautions i have to take?
3. for changing the root password.
login to linux as a root
$passwd
$newpassword
$confirmpassword
4. for changing the oracle's system password.
sql>alter user username identified by newpass
5. I am having 3 shell script for online backup, inthat script im using the oracle's system password, that also i will modify to the new one.

What else i have to do?

waiting for your suggestions.....

Thanks & Regards

Proceed with your changes. Nothing in Oracle uses the root password. As long as your scripts have the new SYS password everything should be fine. For security make sure no one but the oracle account has read/write/execute permissions to those scripts.
