ORA-21561:OID generation failed

遇到一个非常奇怪的问题，Linux5.8 + Oracle 11.2.0.3

启动数据库时候报错：

[oracle@tivoli02 ~]$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Thu Oct 23 21:23:16 2014

diagnostic_dest="/u01/app/oracle"
LOCAL_LISTENER='' <<<<<尽管置空也无济于事

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。
