通过对上述trace信息的检查发现除了SQL auto adviser外，还有一条SQL语句出发了该问题，该sql 语句在plsql或者服务器端执行都会出现如下报错：
    ORA-03113: 通信通道的文件结尾
    会话 ID: 191 序列号: 1
同时出发ora-07445报错。
通过netalink查看发现应该是12C的一个bug，通过修改如下参数可解决：

ora-07445: exception encountered: core dump [evaudc()+180] Rediscovery Notes When query has all of below:
1) special ordering operator in outer query(example: ORDER BY ...DESC/ASC
NULLS LAST)
2) query having view on which view merge takes place
3) there is FI usage i.e. order by column is fetched from Functional index Workaround alter session set "_replace_virtual_columns"=false;
or
