查询oracle metalink了解到这是oracle 11.2.0.1自身的一个Bug 9445675（文档 ID 1361107.1），与oracle数据库的绑定变量有关  

根据trc文件提示到的sql可知，sql语句确实使用了绑定变量，解决改问题的方法有3种：

1、取消数据库的绑定变量窥探：alter system set "_optim_peek_user_binds"=false;

注意取消绑定变量窥探对数据库有影响，会改变sql的执行计划

2、对数据库打补丁

PSU 11.1.0.7.8 Patch 12419384 includes Patch:9703463

For 11.1.0.7, Patch 9243912

Patch:9703463  can also be applied individually but requires PSU 11.1.0.7.6 

Patch:8625762  may also be applicable to databases version 11.1.0.7

Patch:18841764 fixes the SQL Loader issue that may affect database version 12.1.0.2

3、升级数据库到11.2.0.3及以上版本

由于项目功能使用紧急，临时取消数据库绑定变量，应用功能能够正常使用，事后再做oracle 11.2.0.1 to 11.2.0.4的升级。
