Today I have done about connect oracle database with ruby on ubuntu linux 7.04 ( Feisty Fawn) . The oracle database I use only instant client not full client. The joint for ruby and oracle I use ruby-oci8 that the great ruby interface.
The way to install the instant client for oracle on ubuntu I get it from Ubuntu Forums . How to Install Oracle Instant Client and PHP OCI8 module . That I install only oracle instant client not php and oci8 .
And the last one, set the TNS_ADMIN to the directory that contain tnsnames.ora file. You can see the solution from psyko.org
That work fine for me.
