Hi Ingmar

You can code the idle() event of the application object. Just do a HALT CLOSE in that event. The "CLOSE" will guarantee that any code in the application's close() event will be executed first.

See on how to setup the Idle() event: https://docs.appeon.com/pb2019/powerscript_reference/ch10s307.html

For good practice: do an "Idle(0)" before doing the HALT CLOSE to off the timer on the idle event.

Thanks for this.

I actually need the opposite feature, a "stay alive" option. After X minutes I will sent a query t o the database to keep my connection open!

Hi Olan,

We do the "exact" same thing for our Oracle database connection, but ... we do it with a timer() on a timer event of our mdi frame window. Theoretically, if a user just opens some window, and does nothing else (database related), like for example: "moving the mouse around for some minutes", then your idle() event isn't fired (since the app isn't 'idle'). You could still be disconnected from the database, since the idle event of the app object won't run and your "heart beat select" won't execute.

regards
