I am assuming that you mean something along the lines of a change occcurs in the database, a database trigger fires, and an apex application gets notified in some way and refreshes its screen?

If thats the case, then there does not appear to be a native way in Apex to do that.

I asked some Apex people on ideas to do it - some of their input paraphrased below:

In web apps, generally speaking, we need to use web sockets to push data from the server to the client so you’d have to place a web server that supports this in front of ORDS, for example, Node4ORDS ( https://github.com/OraOpenSource/node4ords )

Then you could use CQN to push from DB to Node.js. See https://jsao.io/2015/02/real-time-data-with-node-js-socket-io-and-oracle-database/ for some details on this.
