I am using Oracle 188.8.131.52 on Linux 6.8. I am using OSB to take a backup to tape. After an unknown host name error in the backup log, I edited the /etc/hosts file and restarted the server.
After restarting, when I enter obtool in the DB server (which is a client) it says
failed to read configuration data - Network is unreachable
Can anyone please throw me some light on this issue?
