安裝過程中長時間無反應，日誌中報Caught UnknownHostException

在安裝資料庫時，出現如下介面後，長時間無反應

從日誌中，我們可以看到如下資訊

[oracle@racdg logs]$ tail -f oraInstall2013-08-15_09-06-19AM.err

Caught UnknownHostException: racdg: racdg

在/etc/hosts中新增IP和主機名的對應關係

[root@racdg ~]# vi /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1               localhost.localdomain localhost

::1             localhost6.localdomain6 localhost6

 

192.168.152.200 racdg

 

退出，重新安裝，該問題解決。
