OCI-12658

ANO service required but TNS version is incompatible

Cause

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.


Action

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