Matillion to Oracle Connectivity

I'm new to Matillion and in search of a detailed guide that goes step by step configuration of Matillion to Oracle environment. I need it to explain what we need to provide to our Oracle DBA team as far as whitelisted IP's, also what ETL\service accounts we can use etc.. The scope of this project is to use Matillion to build an ETL to extract data from Oracle databases and load into a newly constructed Data Warehouse in Snowflake.
