在执行dbca的时候，抛出libclntsh.so.11.1+0x6ef23e的异常。
oracle官方给出的原因是：
If the hostname in the /etc/sysconfig/network config file is set as "localhost",it will generate the error when using DBCA to create Database Instance and then the DBCA will be crashed.
There are more detail infomations in the hs_err_pidxxxxxx.log log file about the getting hostname as bellow:
解决方案：
1、修改主机名
#vi /etc/sysconfig/network
HOSTNAME=new_hostname
2、修改/etc/hosts对应的地址和名称
#vi /etc/hosts
172.24.1.12 new_hostname
重启服务器后，该异常消除。
