(Doc ID 2023160.1)
Last updated on OCTOBER 21, 2024
Applies to:
JDBC - Version 10.2.0 and laterOracle Net Services - Version 12.1.0.2 to 12.1.0.2 [Release 12.1]
Information in this document applies to any platform.
Symptoms
On : 10.2.0.4 version, Thin JDBC driver
When trying to connect to Oracle database 12.1.0.2 using JDBC 10.2.0.4 (using file ojdbc14.jar), error ORA-28040 No matching authentication protocol is returned even though sqlnet.ora file on server side is changed to include :
SQLNET.ALLOWED_LOGON_VERSION_CLIENT=8
SQLNET.ALLOWED_LOGON_VERSION_SERVER=8
and listener is restarted (stop/start).
According to <Document: 401934.1> Starting With Oracle JDBC Drivers, JDBC 10.2.1 must be able to connect to Oracle 12.1.0. But, it does not.
If JDBC is replaced with 11.2.0 (file ojdbc5.jar), there is no error.
