按照網上連接oracle的教程
安裝ruby-oci8-1.0.0-rc3-mswin32.rb
但還是發生了以下錯誤：

繼續查詢發現還需要安裝Oracle Instant Client 或者 Oracle Full Client,並設置好環境變量PATH, 否則找不到所需的DLL。
具體參考：http://ruby-oci8.rubyforge.org/en/InstallForInstantClient.html
database.yml的設置參考如下：
# for oracle
development:
adapter: oci
host: hostname/sid
username: user
password: pwd
