Hello,

i've trouble connecting to an Oracle Database 12c using Devart dotConnect. Last weekend a change in a Company Oracle Database took place, they enabled TLS Encrytion. Since today we get following error when trying to connect with dot connect in direct mode.
ORA-03113: end-of-file on communication channel.

Connecting without Direct mode oder SqlDeveloper working withot any problems. I didn't have access to the Database, on higher level then the ID provided me by the Company.

Is there anything we need to Activate in the OracleConnectionStringBuilder to use TLS in Direct mode?

Details of all :
Devart Version:
Devart.Data v. 5.0.1431.0
Devart.Data.Oracle v. 9.0.7.0

ORA-03113: end-of-file on communication channel

dotConnect for Oracle does not support encryption in the Direct mode. We will investigate the possibility of implementing encryption in the Direct mode, and notify you about the result. But we can't tell any timeframe at the moment.

Hey,
I have the same problem and I really hope you guys make it possible
Thumbs up!

I like dotConnect and I want to use it further for many years. Please find a solution.

Best regards...

Thank you, Boosa, for your feedback. As we wrote before, we will investigate the possibility of implementing encryption in the Direct mode, but we can't tell any timeframe at the moment.

SSL/TLS is supported in the Direct mode. Please upgrade to dotConnect for Oracle v9.11.1034. Refer to https://www.devart.com/dotconnect/oracl ... pport.html.
