Dear Erman,

Is it possible to create dblink from 11.1 version ro 12.2 oracle database?

We are facing error while testing connectivity

ORA-28040 No Matching Authentication Protocol

We came across this note id 12c and Later Releases: ORA-28040 After Upgrade: No Matching Authentication Protocol (Doc ID 1957995.1)

Do we need add below parameters in 11.1 database or 12.2 database?Please suggest

SQLNET.ALLOWED_LOGON_VERSION_SERVER=11
SQLNET.ALLOWED_LOGON_VERSION_CLIENT=11


Thank You
