In 12c Flex, Oracle says that we can install the 12c database in Hub node and leaf nodes are ASM clients.
I want to know if I can configure my application servers as leaf node? Is it possible for me to have my leaf node configured as an application server and thus talking to the Hub node which has the database?
Also, how does the leaf node communicate with the Hub node? Through a private interconnect? or through something else?
I am sorry I couldn't quite find the documentation for this which helps me understand these two things clearly.
Thanks in advance!
