No, this is not a real Sinatra error :).
This is the personal homepage of Elad Meidar, a web developer and an entrepreneur specializing in Ruby on Rails. I hang around in Israel, and i am currently having the best time of my life over at Fiverr.com
I am a proud member of RailsBridge, Helping new Rails developers get into our world and also contributed a few Patches to the Ruby on Rails core.
Well, generally i use Oracle for my large scale applications.
Some people might say that it’s not too-competible with Rails, but using the oracle_enhanced_adapter didn’t pop up any special issues (it even supports Oracle’s bind variables technique).
The Oracle Cloud Deployment tutorials on Oracle’s website contains explanations, PDFs, tutorials and demos on how and when to deploy Oracle DB in the cloud.
Extra guides include backup and recovery practices.
You're seeing this error because I think it is funny.
