【2】问题的解决方法

Metalink上面居然没有发现症状一样的问题，关于ORA-03137的错误，问题有很多，常见的问题有JDBC、绑定变量窥视、ORACLE的BUG等，Metalink也提供了一系列的排查方法，具体如下：

2.1 绑定变量的窥视

解决方法：SQL> alter system set "_optim_peek_user_binds"=false;

弊端：关闭绑定变量的窥视，会导致当SQL语句使用绑定变量的时候，产生的执行计划可能会出现不准，在生产环境中要长期关闭该特性需要认真测试；

2.2 更新数据库最新的PSU，当通过禁用绑定变量后数据库不再报错，可以应用每个数据库最新的PSU。或者当禁用绑定变量的时候也继续报错，也可以考虑应用PSU进行测试；

以下是相关的PSU信息：
PSU 11.1.0.7.8 Patch 12419384 includes Patch:9703463.
For 11.1.0.7, Patch 9243912 can be applied on top of 11.1.0.7.8 ( no conflict).
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
2.3 更新数据库到11.2.0.3这个版本
在ORACLE 11.2.0.3这个版本中可以解决所有的ORA-3137的错误；

2.4 联系ORACLE SUPPORT解决这个问题 经过以上操作，你都踩到这个地雷了，说明楼主平时烧香少，，需要联系ORALCE的大神么出手；

【3】总结：经过验证发现运行alter system set "_optim_peek_user_binds"=false后报错就消失了；
