Is it possible that Smart view Installer 18.104.22.168.x, to have the Smart view executable like earlier versions when clicked on Tools->Install->Smart view in Workspace console?
NO it is not possible.
In 22.214.171.124.x, users are no longer prompted to download Smart View from the server, but instead the link in workspace redirects you to Oracle Techniet where you can download the latest version of Smart View.
In workspace this can be changed in server settings on the workspace console using an admin user.
i.e Navigate->Administer->Workspace settings->Server Settings.
