Error :*** Alert: Your local host name database file (typically /etc/hosts) is not configured properly. This file should have an entry of the form: 

 <IP_ADDRESS> <FULLY_QUALIFIED_HOSTNAME> <ALIASES> 

On Solaris systems, the following files should also contain the fully qualified hostname, including the domain name:

/etc/nodename, /etc/net/ticlts/hosts, /etc/net/ticots/hosts, /etc/net/ticotsord/hosts, and any files in /etc whose names begin with "hostname" 

In some of the above files, the hostname may occur more than once, in which case all occurrences should be changed. Please correct your local host name database file, reboot the host, and restart the installation. Failure to properly configure this file may result in product runtime issues regarding proper hostname resolution. ***

原因

  • /etc/hosts の設定不良。
  • 」という書式で記述していなかった。具体的には以下の通り。

正: 192.168.0.21 oas.ablog.com oas

対処

  • /etc/hosts の記述を修正する。
