I don't use oracle a lot, but none of the examples on connectionstrings.com[^] use the providerName the way you have it. Also, your connection string doesn't have a closing double quote...so you could you make sure you pasted it correctly. You've got something funky with the quotes around System.Data.OracleClient.
