I am attempting to connect to ORACLE11g however i am getting the  
following error:

“OCI Library Initialization Error”

IT always errors on OCIENV.init(). I cant see anything wrong on the ENV  
configurations.

Has anyone had this problem, or any suggestions on where i should look  
for anwers?

I am using the following gems:  
ruby-oci8 (1.0.4)  
activerecord-oracle-adapter (1.0.0.9250)  
activerecord-oracle\_enhanced-adapter (1.2.0)  
activerecord (2.3.2)

TNS\_ADMIN, ORACLE\_HOME are configured.

The output is below:

\*\* Invoke db:migrate (first\_time)  
\*\* Invoke environment (first\_time)  
\*\* Execute environment  
\*\* Execute db:migrate  
rake aborted!
