implement subscription to db events

vbuehringerMar 3 2015 — edited Mar 4 2015

in the evolution from rest-services to websockets it should be possible to leverage the publish/subscribe functionality

inside oracle-db

a node program registering for db-events with callbacks would be the natural solution for reacting to events in the database and propagate

the changes via websockets to the webclients

the functionality is already in the oci-driver

Look at CREATE USER IDENTIFIED GLOBALLY ..
I'v never done it myself, but saw a colleague demonstrate it once at a conference. I believe you have to install Oracle Internet Directory (OID), and you can then sync that with LDAP. Sorry I can't provide more details, but at least I can confirm that it is possible. Perhaps someone else will weigh in with more details.
This should help you get started: https://docs.oracle.com/en/middleware/idm/internet-directory/12.2.1.3/index.html
