I've switched to using the managed assembly and I've been able to connect to many 11g databases, but a new one I need to connect to gives me ORA-12537: Network Session: End of file when trying to connect. All of these databases are running the same version and platform (AIX).
I've turned on client tracing and see that it gets past the NS handshake but fails at the TTC negotiation (specifically, it looks like the server's response is empty or something). I can send the full trace if needed.
I'm using the odp.net,managed package from NuGet v121.1.2. Server version is 11.2.0.3. I can connect using VS and other dev tools (TOAD) but can't from .net using the managed driver.
Any suggestions?
Thanks.
