I have Cloud Control 12c Release 3 set up and monitoring many hosts and targets. However when monitoring my RAC (2 nodes), it cannot connect to the database instances (although it shows them as up). I get the message "IO Error: The Network Adapter could not establish the connection". I can see that the connect descriptior is using the vip, rather than the hostname.
How can I update the connect descriptor within Cloud Control to the correct values?
