I want try to use FAN (Fast Application Notification) in Java Application. I found, that FAN cannot work without Grid and / or RAC. I found a lot of answers, how I can install Grid and RAC on multiple machines (clusters). But I didn't find nothing, how I can install Grid and Oracle Database (in my situation 19c) on same machine right. Is it possible?
I tried to install Grid with DB on my machine already. But I have problems with Listener. Because I have 2 ORACLE_HOME (one for Grid and second for DB).
Can somebody help me with it?
As far as your listener goes, one single listener, running from one single oracle home, is quite capable of - indeed, WAS DESIGNED FOR - handling multiple databases of multiple versions running from multiple homes. In the case of a grid infrastructure environment - both the grid home and the separate database home on one server, the listener should be running from the grid home. You do not need (or want) a listener for every home on the server, and you do not need (or want) a listener for every database on the server. The listener is just a switchboard, listening for incoming database connection requests, then servicing those requests regardless of which home a database is running from.
