----- Current SQL Statement for this session (sql_id=fcugjhv161x8v) -----

SELECT *               FROM (SELECT 

由select语句引起。

mos上给出这是bug

This problem is introduced by the fix for 11659002 included in 11.2.0.3.

With that fix there is a small timing window where SELECT statements could hit

ORA-600 when the select uses a partitioned index that is concurrently dropped

right around the time of the parse (hard or soft) of the SELECT.

当使用分区索引时，并发drop会引发此bug。
