Listener Configuration
I created a testing oracle database server installed with Oracle 12cR2 database. It is a virtual machine with Oracle Linux 7.4 installed.
For whatever reason, once I created the listener, it always bonding with tcp6 instead of tcp. I disabled ipv6 and the bonding is back to tcp. However, when I created the new listener, the hostname is automatically to ol7-122.localdomain. When I changed to the IP or DNS name of the server, the listener couldn't be started. Anyone has any suggestion on troubleshooting?
Thanks,
Ling
