Oracle 12c (direct mode) : ORA-03113: end-of-file on communication channel

Post by dcoracle600pro » Thu 06 Jul 2017 10:31

My application use 9.4 version of devart.

With 9.4, I can connect to Oracle 11.2 database.
With 9.4, I cannot connect to Oracle 12c (12.2.0.1.0). When I execute Open() instruction, I have this exception : ORA-03113: end-of-file on communication channel.

You can see in my print screen the details of the problem.

Hopefully it will be resolved soon.

We have fixed the bug with the "ORA-03113" error when a Windows account is not in a domain in the Direct mode. We will post here when the corresponding build of dotConnect for Oracle is available for download.

I have the same problem but in Oracle 11R2 (Devart version 9.4).
The windows account was not in a domain and the direct connection wasn't possible.

In solution, I changed the listener authentification mode in NONE instead of NTS

How specifically did you do this?
