今晚使用 DBCA 建库的时候，进入如下界面后，把机器开着就去洗澡去了。 结果洗完澡回来，发现进度条还是 2%，感觉不对劲，于是就进安装界面显示的安装日志看看，发现数据库报： ORA-21561: OID generation failed [oracle@prod dss]$ pwd /u01/app/oracle/cf

经过反复排查，发现这台虚拟机是复制的，我修改 /etc/sysconfig/network-scripts/ifcfg-eth0 和 /etc/sysconfig/network 文件后，忘记修改了 /etc/hosts 文件。

/etc/hosts 文件中的 host IP 与 hostname 映射仍然是源主机的，果断改正后重启服务器，然后重新安装就很快 pass 了。
