Websphere 7 response time

[Lei]

In one of my application, the big query from database will cost more than one minute to return and show the results. The websphere default configuration will report some internal server error (code 500) to the user. I think there should be one place to tune the paramerters in websphere like response time. Although it's not a good design to let the query running this long but how to deal with this situation based on current condition?
