Question
For one of my projects I need to use an Oracle database on a Rails app.
For my local development, I've installed Oracle VM VirtualBox with the package Oracle Developer Day . I successfully deployed, launched the VM, logged in and even created a user on SQLPlus with admin rights.
On my mac OSX Mavericks, I've installed instant client from Oracle as well as the following version of ruby-oci8 and activerecord-oracle_enhanced-adapter

Russian gem ruby-oci8', '~> 2.0.6'
gem 'activerecord-oracle_enhanced-adapter', '~> 1.4.1'
My config file for my dev database is the following database.yml
development:
adapter: oracle_enhanced
host: 192.168.2.170:1521/myprogram_development
username: my_new_sql_plus_username
password: my_new_sql_plus_password
On Oracle VM side, I've set up my network as the screenshot shows
When I connect my VM I have the same IP as the database.yml file above
All that looks fine (I've followed every steps of this tutorial and also tried this one ), but when I try my rake db:setup command or to access the db via OCI8.new("my_new_sql_plus_username", "my_new_sql_plus_password", "//192.168.2.170:1521:1521/orcl"), I have the following error message.
rake aborted!

Thanks in advance for your help
Solution
I figured it out. So couple of problems: First the network config. Use Bridged adapter instead of NAT, like below
Second, the config file in the rails app (database.yml), don't forget the 2 slashes in front of the IP ...
development:
adapter: oracle_enhanced
host: //192.168.2.170:1521/myprogram_development
username: my_new_sql_plus_username
password: my_new_sql_plus_password
And it's all good !
