Configuring Oracle Listener in OpenSuse Leap 15.0

Question

Having trouble getting Oracle XE 18c installed on OpenSuse Leap 15.0... When running the configuration script:

joshua@linux-t1zu:~> sudo /etc/init.d/oracle-xe-18c configure
[sudo] password for root: 
/bin/df: unrecognized option '--direct'
Try '/bin/df --help' for more information.
Specify a password to be used for database accounts. Oracle recommends that the password entered should be at least 8 characters in length, contain at least 1 uppercase character, 1 lower case character and 1 digit [0-9]. Note that the same password will be used for SYS, SYSTEM and PDBADMIN accounts:
Confirm the password:
Configuring Oracle Listener.
Listener configuration failed. Check log '/opt/oracle/cfgtoollogs/netca/netca_configure_out.log' for more details.

I see where it first says something along the lines of

Host name or host name resolution is misconfigured. linux-t1zu: linux-t1zu: Name or service not known

So does this mean I need to configure localhost? If it is already not? I'm honestly pretty much lost here. Any advice is greatly appreciated.

Answer 1

I was able to answer my own question. Reading this page from the Oracle Docs in the Networking section, I edited my /etc/hosts file as suggested, adding my hostname. At first, I did not add it in the Short-Hostname column and that did not work. However, going back and adding it there worked.

So like this:

In the terminal, if the output of

hostname

was tomtom

then my /etc/host file looked like this in the specific applicable portion:

    # IP-Address  Full-Qualified-Hostname  Short-Hostname
    #
    127.0.0.1         tomtom                   tomtom

Hope this answer helps any others facing this issue.
