Dear all,
We both know that, in previous version, ASM Instance running on the same host with DB Instance. The DB Instance will do the local connect via IPC to ASM Instance.
Now with Oracle Flex ASM 12c, DB Instance can connect to remote ASM Instance.
1) ASM Instance now will register with ASM Listener which only running on the same host with ASM Instance. Is this correct ?
2) If we have 5 nodes cluster, we decide to use 1 dedicate physical network for ASM network and ASM cardinality =3. So we will have 3 ASM Instance running on 3 host and also have 3 ASM listener running on the same hosts ??
3) How can DB Instance know exactly what ASM Instance it have to connect to? What is its IP address and port ?
4) Oracle say that "Database instances are connection load balanced across the set of available ASM instances". How ? We do not have anything like SCAN for this connection.
5) I see that now ASM Instance have it own password file. What will use this password file ?
Hoping to see your sharing. Many thanks
