网上查的解决办法：
1:临时的解决方法
如果执行计划中是hashjoin造成的，在会话层中设置"_hash_join_enable"=false，如：altersessionset"_hash_join_enabled"=false亦可;
如果执行计划是hashgroupby造成的，设置"_gby_hash_aggregation_enabled"=false
2:根本的解决方法
2.1.优化sql语句，避免遇到bug；
2.2.升级
(1)将数据库升级psu到10.2.0.5.4和11.2可以修正该问题
(2)对于10.2.0.5.0到10.2.0.5.3的版本，打PATCH7612454来避免改错误(该补丁替换lib中的kcbl.o文件)。
通过临时解决办法解决问题示例：

altersessionset"_gby_hash_aggregation_enabled"=false

--先尝试一种，如果一种解决了，就没必要设置另外一种了。
然后再次执行上面的查询语句，不报错啦，嘎嘎
成功啦，(*^__^*)嘻嘻……
让开发人员在程序里加上这条命令即可。
