Gaining insight into the Performance of camunda Process Engine

Written by Daniel Meyer on , under Execution category.
The camunda process engine has a very active codebase and is constantly evolving. Only last week we did a major refactoring, re-implementing the way the BPMN Boundary Event, Event Subprocess, Terminate End Event and similar constructs work. In summer we introduced an activity instance model and rewrote the history implementation, turning it into a fire-and-forget event stream. We also constantly add new features such as incidents and many others. When doing such refactorings, the extensive process engine testsuite gives us the confidence that we do not break existing functionality from a functional perspective (process engine currently has 1669 Testases, over 500 were added last year).

Get your Tasklist as RSS Feed

Written by Jakob Freund on , under Execution category.
I don't like watching my Tasklist all day. Getting email notifications for tasks that I should complete is nice, but sometimes I don't want to complete the task right after being notified but still need to keep in mind there is something pending. This is how I came to create a simple PHP script that exposes my tasks as an RSS Feed. I can use that in my personal master dashboard (Microsoft Outlook) to keep track of my camunda Tasklist.

camunda Modeler as a standalone tool

Written by Nico Rehwaldt on , under Execution category.
As a small little side project I was working on a standalone version of the camunda BPMN 2.0 modeling plugin for Eclipse. The camunda Modeler standalone offers nice little features to better integrate with the operating system and focuses 100% on process modeling. It is available for Mac, Linux and Windows. Update (2014-02-05) The project is now an official part of camunda BPM. Read the offical announcement or check out its home on camunda.org.

How to use Generated Task Forms with camunda BPM - Screencast

Written by Daniel Meyer on , under Execution category.
I prepared a screencast in which I show how to use the Generated Task Forms Feature we introduced with camunda BPM 7.1.0-alpha1. Generated task forms allow you to create simple task forms without the need to write any HTML code. Please also have a look at the Generated Task Forms Quickstart. I dedicate the first 3 minutes to show you guys how to do the project setup. If you are familiar with setting up a camunda ServletProcessApplication, you can skip ahead to about 3:00 and start there.

Monitor collaborating executable BPMN 2.0 processes in cockpit

Written by Bernd Rücker on , under Execution category.
In a current customer project we faced the issue that there were two executable processes - independent of each other. So far - so normal. But these two processes had to sync status here and there - so they were clearly related, but not by using a Call Activity. BPMN 2.0 allows this by communication via messages as shown in the following example. But how to keep track of this in monitoring? We developed a small cockpit plugin to show the related process instances - see below.
