comment Why is a Full Database Backup (as opposed to a level 0 backup) required in Oracle after switching to ARCHIVELOG mode?
Ah, good to know. I found it confusing as "whole database backup" is mentioned nowhere in the section on incremental backups. Don't want to be -too- autistic on this, but it is -not- mentioned explicitly in the documentation that a level 0 backup is a whole database backup. So at the very least, the documentation is incomplete.

comment Can I delete an Oracle “Whole database backup” while a level 0 backup is being created?
This is from the 2 Day DBA manual. I'm running this for the first time, hence it starts with creating a level 0 backup. (page 9-23). So, it -is- creating a level 0 backup.

Your explanation confirms my suspicion. Just wanted to be sure my confusion was indeed caused by a mistake in the documentation. I'll do some testing later on and try to confirm...

So, a level 0 backup is also called a "whole database backup"? Or the first excerpt is wrong in saying that a whole database backup is required, and should have mentioned that a level 0 backup would also be ok?

comment Oracle 12c Express Enterprise Manager on Centos 6.5 is not reachable
Does your server have multiple network adaptors? Check listener.log at the time you try to connect to the webpage. Does it contain a TNS-12518 error? Is the IP address mentioned in this error the same as the IP address your hostname maps to? Or is it the IP address of one of the other adaptors? Is the problem solved if you disable the other adaptors?

host_address returns an ipv6 address, the host returns the hostname in uppercase, without the domain attached. I've also ran an RDA report, and that showed "DNS Lookup - FAILED". Also, Cloud Control fails to install when using the hostname, but works when using the IP address. I'm now certain this is some kind of DNS issue, I'm just clueless on how to debug/analyse...

I'm running all tests on the db host. Pinging hostname and ipaddress, and tnsping to CDB and PDB's works fine. Nice catch about the refused connections! I've restarted the listener, and used the hostname-EM-URL: same problem "webpage not available", and lsnerctl shows no entry yet for XDB. When using the ip-EM-URL EM loads (slowly) and I get an XDB entry, but no refused connections. I have no idea what to make of this, but maybe it does to you?

Any idea on how to debug, track the exact cause?

The hosts file is empty. Not sure how exactly the hostname is managed, but the network uses an ActiveDirectory server where the server is registered with its hostname, and the DNS servers recognise it as such.
