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/ASCNULLS LAST)2) query having view on which view merge takes place3) there is FI usage i.e. order by column is fetched from Functional index Workaround alter session set "_replace_virtual_columns"=false;oralter session set "_simple_view_merging"=false;alter session set "complex_view_merging"=false;
