问题总是会有的，有时候解决问题也是一种乐趣，而处理问题的关键是“不抛弃、不放弃”。
症状：
FC6（ kernel 2.6.18-1）上安装的Oracle10g
修改了IP地址，从原来的192.168.1.* 到 172.16.0.*
系统重启后，发现oracle监听无法启动。
提示：
ORA-00600: internal error code, arguments: [%s], [%s], [%s], [%s], [%s], [%s], [%s], [%s]
oracle数据库也无法启动，提示数据库无法连接。
看似很简单的问题，以下是曲折的问题解决过程：
googleing ： keywords： ORA-00600: internal error code, arguments:
翻了一通，说是什么头晕眼花，没有收获。
查询oracle的监听（listener.ora）配置。
# listener.ora Network Configuration File: /opt/oracle/product/10g/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /opt/oracle/product/10g)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost.localdomain)(PORT = 1521))
)
)
发现没有任何改动。
里面只有host配置，并没有具体指定某个IP。
重新修改网卡的IP地址：
vi /etc/sysconfig/network-scripts/ifcfg-eth0
# nVidia Corporation MCP61 Ethernet
DEVICE=eth0
HWADDR=10:c0:f8:b9:1c:30
IPADDR=172.16.0.252
NETMASK=255.255.255.0
ONBOOT=yes
GATEWAY=172.16.0.1
TYPE=Ethernet
Reboot Server 。。。
一分钟过后，oralce监听仍然无法启动。
#setup
直接配置网卡的设置
这里出现了错误，修改完ip后，无法save 只有quit。
提示如下：
出现一个未解决的异常。这极可能是一个程序错误，请将其崩溃组合码转储入一个文件，
然后在 https://bugzilla.redhat.com/bugzilla 提交一份关于 system-config-network 的详细错误报告。

googleing 。。。。。。。。。。。
未果。
郁闷中。难道让我重装oracle？
虽然作为一台测试服务器，重装oracle也是一件比较让人不爽的事情啊。
接着google。。。。。。 keywords： erverything （先看了会娱乐八卦再说。）
无果。。。
我无语了。。。
半小时后。
偶然发现Linux下面的提示如下：
[root@bogon]#
这个bogon是什么东东哩？
是不是中毒了，这台机器的防范可是超级薄弱啊，所有口令都是12345678，哈哈
赶紧看/var/log
看了一遍所有日志，和配置等等，没有发现异常。
使用了chkrootkit http://www.chkrootkit.org下载 chkrootkit.tar.gz 最新版本 chkrootkit-0.48
./chkrootkit > result.txt

#hostname
bogon
继续google... keywords: hostname bogon
解释说可能是内网防火墙所致，跟IP段或许有关系。
bogon是指那些不该出现在internet路由表中的地址
这些地址应该包括：
1，私有地址如10，172.16-32,192.168.....
2，还未正式分配出去的地址
Bogons are prefixes that should never appear in the Internet routing table, and obviously should not appear as the source address in any packets you receive.
联系起来最近的操作，恰恰证实了这一点。
昨天刚刚把ISA2004架设好，内网网段从192.168.1.0/24 改到了 172.16.0.1/24
但是究竟是什么修改了Linux的hostname了呢？
先不管他，修改hostname,改为原来的hostname。
#hostname localhost.localdomain
vi /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
172.16.0.252 localhost.localdomain localhost
#reboot
系统重启后提示变为：[root@localhost]
#hostname
localhost.localdomain
正常了，跟oracle中监听的配置一致。
切换到oracle用户。

总结：
如果您的oracle有这样的错误
ORA-00600: internal error code, arguments:
先看看是不是hostname被修改了？？
