The Oracle DBA's

Receiving error: Application is getting below error post up gradation while trying to connect to DB ORA-28040: No matching authentication protocol Cause: It might want you to upgrade the JDBC version. Resolution: You may  align one parameter mentioned below in sqlnet.ora file:   sqlnet.allowed_logon_version_server=8   (A setting of 8 permits most password versions, and allows any combination of the dba_users.password_versions values 10g, 11g, and 12c.) OR you update your JDBC version and try to connect again. Thanks & Regards Nikhil Kumar.
