Answer 1

Make sure you set the appropriate environment variables:

You can use this script:

$ . /usr/local/bin/oraenv

Answer 2

It all depends on how you plan log in to your system on a regular basis. One approach is to put the required environment variables in your .bash_profile, assuming you are using bash. It's not best practice to do that for the oracle user, in case you end up running more than one database (and thus have more than one SID).

I recommend reading read the documentation on how to set your environment permanently:
