ORA-07445&ORA-00108错误案例

由于需要ORACLE的UAT测试环境，克隆了虚拟机后，修改IP地址后，启动实例遇到了ORA-07445 &ORA-00108错误.

案例环境：

SQL> select * from v$version;

解决方法:

 

在ORA-07445[kslgetl()+120]/ORA-00108错误解决这篇文章了解到可能是主机名不能被正常访问导致，于是从下面验证后，发现是自己不小心编辑/etc/hosts

[oracle@getlnx01uat ~]$ hostname

getlnx01uat.esquel.com

[oracle@getlnx01uat ~]$ ping getlnx01uat.esquel.com

PING getlnx01uat.esquel.com (192.168.xxx.xxx) 56(84) bytes of data.

[oracle@getlnx01uat ~]$ 

 

 

[oracle@getlnx01uat bdump]$ ls -l /etc/hosts

-rw-r--r-- 1 root root 260 Jun 11 13:52 /etc/hosts

[oracle@getlnx01uat bdump]$ hostname

getlnx01uat.esquel.com

[oracle@getlnx01uat bdump]$ ping getlnx01uat.esquel.com

ping: unknown host getlnx01uat.esquel.com

[oracle@getlnx01uat bdump]$ more /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1               localhost.localdomain  localhost

xxxx           getlnx01uat.com  getlnx01uat

如上所示，hostname为getlnx01uat.com，这个可能是我编辑/etc/hosts时，不小心误删除了一些hostname一些字符。编辑修改hostname后，重启数据库问题解决

[root@getlnx01uat ~]# more /etc/hosts

# Do not remove the following line, or various programs

# that require network functionality will fail.

127.0.0.1 localhost.localdomain localhost 

xxx.xxx.xxx.xxx getlnx01uat.esquel.com getlnx01uat
