I need help with the network configuration of an oracle database. The database is installed in a virtual box guest:
VirtualBox - host: Fedora 30
VirtualBox - guest: Oracle Linux 8
Oracle database 18c: installed in guest, port is 1521, service name XE
I used a network bridge to access the guest from the host e.g. via ssh. That works. But although the firewall inside the guest is switched off I cannot connect to the database. I am trying to connect with a tool like dbeaver or sqldeveloper. On the host no oracle client is running. I don't know whether that is ok. It looks like I am missing some configuration.
tnsnames.ora and listener.ora are like standard (localhost, port 1521, xe).
Could anybody help me?
