Hi Malik , how scan listener connect to local listener to get the information any connecting there and how it communicating can u explain?
@stalinjaviermaciasgomez3676
@stalinjaviermaciasgomez3676 3 года назад
Correct me if I'm wrong, please. If we don´t have a local listener in X node, the SCAN listener will try to establish a connection but it will fail, therefore it will try to connect to another node until it finds an available local_listener to connect to the database. The advantage of having a local_listener in the nodes is to receive the incoming connections to connect to the database. This can be translated as load balancing, SCAN listener will try to establish a connection to the listener with less load. Thanks for your tutorials Malik, they have been very useful. Regards.

Nopes its not like that. If you have local listener then scan will pass the connection to local listener otherwise scan it self will connect to database.
