install oracle client on ssis prod server

I know people have asked this question before
but my question is, i have SSIS package that have the oracle sources.
the packages run perfectly fine on my local machine with my credentials

now it is time to deploy the packages onto the SSIS prod server.
1) should i install the oracle client on the ssis server and attunity drivers on the prod box?
2) what permissions does the service account should have to run the packages in the prod box?

Thanks
