  1. EPM 2007Server-Side Events A Statusing Example msepm.hsquared.be

  2. Agenda • Eventing Architecture • Server-side events and the Queue • Creating an Event Handler • A statusing example • Deploying an Event Handler • Event Handlers and config files

  3. Eventing Architecture • Eventing Service is part of core SSP application • Event Handlers in WSS config DB at PWA site level • Independent event handlers for each PWA • PWA includes Event Catalog to manage custom Event Handlers • Multiple event handlers possible • Pre and post events

  4. Event Handler: sequence Event Source Event Handler Call PSI method Raise Event Event Arguments Invoke Event Handler Cancel pre-event Modified Event Arguments Run custom code End Continue

  5. Pre/Post events and the PS Queue • Pre-events • fired when the Queue job is about to start • NOT when you perform the action! • Post-events • fired when the queue job completed successfully • If queue job fails or is cancelled, the post-event will not fire

  6. Pre/Post events and the PS Queue • Exceptions • Some PSI calls have no corresponding queue job • Pre-event fired before action is performed • Post-event fired after action completed • Ex.: StatusingStatusUpdating, StatusingStatusUpdated

  7. Creating an Event Handler • Create a class library project • Set references • Microsoft.Office.Project.Server.Events.Receivers.dll • Microsoft.Office.Project.Server.Library.dll • Develop the event handler code • Deploy the event handler • Register the event handler with Project Server using Project Web Access

  8. Demo Creating a Project Server custom Event Handler

  9. Statusing limitations • Only published updates in Reporting DB • Not possible to report on ‘missing’ updates • Difficult to implement task update checks • Impossible to detect 0h registrations • No incremental export possible

  10. Event Handler solution • Insert task updates in a custom DB • Add status to keep track of approval status • Saved, submitted, accepted, rejected • Add timestamp and/or export state • Allows for incremental exports

  11. Event Handler solution EPM 2007 DB • Task Updates • Save Event Service Queue • Task Updates • Submit • Accept • Reject Custom DB

  12. Demo Creating a custom Statusing solution

  13. Other scenario’s • Building an incremental export module • Building a real-time export module • Real-time timesheet reporting • No more waiting for queue • Use pre-event to implement task update quality checks

  14. Remarks • NOT a replacement for out-of-the-box statusing flow • Go in and out • Events stop normal code execution. Make sure you don’t add delays! • Keep an eye on performance! • Might be necessary to offload the custom DB to a dedicated server

  15. Deploying the Event Handler • Two options • GAC • Shared assembly • Sign with strong name key! • Bin directory • Code isolation • Register Event Handler in PWA

  16. Configuration File • Event Handler = assembly • No assembly config file • Add configsource to config of calling .dll • Microsoft.Office.Project.Server.Eventing.exe.config • <appSettingsconfigSource=“NameOfYourEventHandler.dll.config"></appSettings>

  17. Demo Event Handler and Configuration File

  18. Questions ? • http://msepm.hsquared.be • Slideshow • Partial Code Sample • Project 2007 SDK
