I am just starting to get my feet wet in Red Hat Linux 7.2 and Oracle 12c. So I spent last weekend devoted to in an attempt to see if I could stand up Oracle 12c on RHEL 7.2.
This error solution is very simple, first, let's understand why this error occurs. It basically has two reasons which are:
1) Your database and service name is not properly set in Oracle environment it should be same everywhere check below parameter values
-ORACLE_SID in oracle environment.
-SID_NAME in tnsnames.ora file.
-SERVICE_NAME in listener.ora file.
2) Host name/IP address is missing, not correct or spelling mistake, so please check the below.
-Check the IP ADDRESS in /etc/hosts file.
-It should be same in listener.ora and tnsnames.ora file
-And it should be able to ping from the local and remote server.
Now see I've also faced the same problem and resolved:

Thanks!
You should check listener log for details.
Find listener log location with:
$ lsnrctl stat
