环境：Version Cognos10.2 单机 非集群
运行报表的时候经常遇到：
错误信息为：
The secondary request failed. The requested session does not exist and the secondary request does not contain enough information to recreate the session. Contact your Administrator.
解决思路：
1：由于是单机排除集群服务的问题
2：JS请求太多 ，超时
那么就是2的问题了
解决办法：在JS关于自动提交的地方修改setTimeOut
把setTimeout的值修改为500,保存js脚本 问题解决.
出现问题记得去官网：

非常感谢：
I solved this for me with a higher timeout value.
setTimeout("promptButtonFinish();",1000);
I looks like the report page needs some time to load. If the load
time takes longer than the timeout value, you get the error mentioned above.
I had the timeout set to 100 and got the error randomly, depending on server and query performance.
