Hi,
im facing a problem with concurrent updates and i'm not sure how this should be handled.

I have a web application (webservice -> spring -> hibernate) which (simplified) handles a counter in the db. the webservice is called with a value x, which has to be added to the current value in the database.

to make it a bit more complicated there are three server instances which are working on the same database.

now my question is -> how do i handle the lost update problem for concurrent writes?
Is there a standard way to handle this problems?
