Sitecore & Oracle: 'Unhandled Execution Error' while connecting

Question

I'm trying to run Sitecore 7 with Oracle and I'm stuck on an error. What I've done is

• Let a DBA create all Oracle users / schemas / tables
• Verified with Oracle SQL Developer that the databases are indeed created, accessible and containing tables
• Make sure I'm using the correct web.config
• Update my connection strings
• Do all the other Sitecore setup that I would normally do (IIS site, VS solution, etc.)
• Install Oracle Client tools (including all possible drivers for my 64-bit system)

I've tried two variations of connection strings:

user id=my_username;password=my_password;Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=my_host_name)(PORT=5151))(CONNECT_DATA=(SERVICE_NAME=my_service_name)))

and this one:

Data Source=my_username/my_password@//my_host_name:5151/my_service_name

Using the exact same information, I'm perfectly able to connect using the Oracle SQL Developer.

When I launch my Sitecore site, I get the following exception:

Unhandled Execution Error

Exception Details: Oracle.DataAccess.Client.OracleException:

[OracleException (0x80004005)]
Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Object src, String procedure, Boolean bCheck, Int32 isRecoverable) +1250
Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, Object src) +91
Oracle.DataAccess.Client.OracleConnection.Open() +4698
....snipped...

Been struggling with this for a day now and would really appreciate some help. Anyone out there running Sitecore 7 on Oracle?

Make sure that you are using the Oracle client tools version 11g, other Oracle versions are not supported with Sitecore 7. See this link for a reference
