From SOA Suite 11g PS2, the Jdeveloper (11gPS2) will have 3 views for a BPEL process.
The 3 views are
- BPEL normal view
- Monitor view
There will be an option on the top right corner of the BPEL process view to select the different views. The sensors are not visible anymore as part of the tabs in any of the activities or structure view. This has been moved and consolidated into a view called Monitor which will help you in creating Sensor and sensor events and publish it to different destinations. There are some new features like Business indicators, counters and intervals introduced for process and business monitoring
