TNS-12658

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

Causa: 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, and so on) be used.

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