启动数据库时候报错：

然后尝试DBCA创建数据库时报错ORA-21561:
在操作过程中发现有异样，检查服务器启动运行时间
[oracle@tivoli02 dbs]$ uptime
?21:54:40 up? 5:07,? 5 users,? load average: 2.18, 2.12, 1.91
说明五个小时前操作系统重启过,再检查/etc/hosts发现主机条目被人修改过,本机IP所对应的主机名域名部分被删除.
新增一个别名,且该别名带有域名
如? tivoli02.robo.com
后来上MOS查了一下，ORA-21561其实是ORACLE未公开的BUG:
Bug 12597261: "ORA-21561 IF HOSTNAME ENVIRONMENT VARIABLE IS NOT FULLY QUALIFIED"
因此，在服务器上做任何改动都需要谨慎，尤其是运行时间长的服务器，存在即有原因。
