im kind of a n00b to Oracle db's, but when i set my dbdriver in codeigniter to oci8, i get the following error, which is weird, providing the extension is enabled in the php.ini file.

I get the following error.

A PHP Error was encountered

Severity: Notice

Message: Use of undefined constant OCI_COMMIT_ON_SUCCESS - assumed 'OCI_COMMIT_ON_SUCCESS'
