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数据库的绑定变量窥探有关
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。
