You may may an issue requiring the use of a thick JDBC driver, but a number of sources suggest adding this string to sqlnet.ora on both the client and server:

SQLNET.ALLOWED_LOGON_VERSION = 10

But Oracle Developer 6i is very old, right? Considered upgrading?

The problem solved

the parameter value must be 8
SQLNET.ALLOWED_LOGON_VERSION=8

on server only



Bug 14575666

In 12.1, the default value for the SQLNET.ALLOWED_LOGON_VERSION parameter has been updated to 11. This means that database clients using pre-11g JDBC thin drivers cannot authenticate to 12.1 database servers unless theSQLNET.ALLOWED_LOGON_VERSION parameter is set to the old default of 8.

This will cause a 10.2.0.5 Oracle RAC database creation using DBCA to fail with the ORA-28040: No matching authentication protocol error in 12.1 Oracle ASM and Oracle Grid Infrastructure environments.

Workaround:  Set SQLNET.ALLOWED_LOGON_VERSION=8 in the $crs_home/network/admin/sqlnet.ora file.
