This document provides an overview of infrastructure automation tools like Chef, Puppet, Ansible, Serverspec, Infrataster and the Infrataster OracleDB plugin. It includes steps to setup the Oracle Instant Client, install necessary Ruby gems, write an Infrataster spec test to query the Oracle database and assert that the db_block_size parameter equals 8192, and execute the spec test with RSpec.
