What is Oracle Notification Services(ONS) in oracle clusterware?
meda Changed status to publish 24/09/2022
It is a feature of oracle clusterware and is responsible for publishing the up and down events on which the oracle fast application notification (FAN) and fast connect failover (FCF) rely on to provide users with fast connection failover to the surviving node during a database instance failure. And the instance failure event triggers the reconfiguration of instance resources.
