I work with IBM Process Server currently. I created a little business process calling different web services (created with HATS). These web services are running quite long. Well the transaction time out came earlier than the webservice call could be requested. Well, my process test failed. This is the (important) part of the error message:

(in english ‘has timed out after 120 seconds.’)

To make it work I increased the Total transaction lifetime timeout. You will find this here:

servers -> Application servers -> [YOUR_SERVER maybe server1] -> Open Container Services -> Click to Transaction Service

You may also mark the correct checkbox to make the process long running.
