Scheduled Task timed out

I have used the Scheduled Task Manager to schedule an aspx page that reads and xml file and updates the sql backend with the readed data.

The page start to execute and reads and update the database with out any problem as long as the xml file does have less that 70 records (nodes), but if I need to upload more data the process stops and reports a 'Timeout' message.

Is there a way to increse the assigned execution time to this aspx page only, if this is possible how could I do it, in order to process two or three times more record for each execution of the scheduled task?

 

Can you tell how to increase the execution timeout on the whole application or pintpoint the url where I can learn how to do it?
