ORA-01017: invalid username/password when connecting to 9i oracle database using the ODP.NET, Managed Driver

I'm trying to connect to 9i oracle database using the ODP.NET, Managed Driver. Every time I see ORA-01017: invalid username/password; logon denied.

Wnen I'm trying to connect to 10g or higher oracle database - all is well.

Also, when I'm trying to connect to 9i oracle database using .Net Framework for Oracle or .Net Framework for OLE DB (MSDAORA) - all is well.

What is the problem?

Solution

  • This seems to be not possible, have a look at ODAC 12c Release 2 (12.1.0.1.2) Installation Instructions, Setup, and Notes

    System Requirements

    • Access to an Oracle Database Server (Oracle 10g Release 2 or later)
