故障现象  

环境：OS:RHEL 4.8   DB:10.2.0.4

今天在dbca创建数据库的时候报下面的错误

[oracle10g@rhel4 ~]$ dbca

原因很简单，由于最近测试GC的问题修改了主机名导致的。

故障处理结果

        经过处理，故障已经解决

故障解决过程

1，查看hosts文件

[oracle10g@rhel4 ~]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1       localhost.localdomain   localhost
192.168.111.2    rhel4.htz.pw           rhel4 
192.168.111.41        gc12r2.htz.pw   gc12r2 

2，查看主机名

[oracle10g@rhel4 ~]$ cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=rhel4.huang.com

3，修改后的network文件

[root@rhel4 ~]# cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=rhel4.htz.pw

4，重启主机

       重启主机后，再次执行DBCA，故障没有再出现
