Still remember my blog on how to installing RubyOnRails On CentOS?
This is the additional on how to connect your ruby to oracle, to be precise rather than a blog, its a weblink. Because after I follow steps on
http://ruby-oci8.rubyforge.org/en/HowToInstall.html
I can connect my ruby to Oracle, the key is Oracle Instant Client (must install it, I choose the RPM version)
to test ruby connection to Oracle paste this code
ruby -r oci8 -e "OCI8.new('scott', 'tiger','ORCL').exec('select * from emp') do |r| puts r.join(','); end"
replace ORCL with your Oracle TNSName or try this
ruby -r oci8 -e "OCI8.new('scott', 'tiger','//server.company.com:1521/orcl').exec('select * from emp') do |r| puts r.join(','); end"
