DataPA allows users to combine multiple subjects into a single query. This potentially allows users to create queries that could run for extremely long periods of time and slow the server as a result.

To prevent this the administrator can set a "Time-Out" period on the server. If a server reaches this timeout period whilst processing a multi-subject query, it will exit and return an error to the user.

To set the server timeout period, you must enter an Environmental Variable from Progress Explorer. From Progress Explorer, right click on the AppServer you wish to configure and open the properties sheet. In the properties sheet, navigate to the "Environmental Variables" option and enter a new variable called PATimeOut. In the value field, enter the number of seconds for the Time Out period.

You will need to re-start the AppServer for your changes to take effect.
