EZZ8331I

Explanation
 The DNS domain name could not be determined using
the specified mechanism.  This message is printed by the domainname
and dnsdomainname commands when the DNS domain name could not be found.
 If
the -c option was specified (the default mechanism), this could be
due to the DOMAINORIGIN keyword not being specified in the client
configuration file (TCPIP.DATA).
 If the -g option was specified,
this could be due to gethostname() returning only the host part of
the fully-qualified DNS name.

System action
 The command ends.

Operator response
 Run the command again using a different mechanism
(-c, -d, or -g option) for retrieving this information.

System programmer response
 Ensure that the DOMAINORIGIN keyword
is specified in the client configuration file (TCPIP.DATA).
