Oracle Solution for Error ora-12658

ORA-12658: ANO service required but TNS version is incompatible

What triggered the Error:

A client process that is running an earlier version of TNS attempted to connect but the connection failed because the server process required that an ANO service (authentication, encryption, etc.) be used.

What should we do to fix it:

Relink the calling executable and retry the connection or eliminate the requirement that the service be used on the server side.
