So your development and deployment environments are both x64 or i64. You're using the command line syntax to access a 32bit version of the Oracle driver because there is no 64bit oracle driver. Actually there is a 64bit oracle driver and we're TRYING to get it working. If successful our SQL job could simply call our package as a package, not as command line, imagine that!

Anyhow, I was shown this handy link of testing for availability of 32bit drivers on a 64bit machine.

Hope this helps,
