Recently, I had to develop a timed job (an instant one-time job) on the SharePoint 2010.
During the development, I asked myself how I can debug the just created job, so I started searching for a solution.
First, the creation / instantiation of the timed job executes on behalf of the currently loggedin user and is executed in the current web-request. So the debugging of this part of the code is quite simple:
Here a screenshot of the Add to process window to select multiple w3wp.exe processes:
This way, you can debug the creation of your timed job.
Now the main issue is, how you can debug the job-processing self. For this, you have to consider some points:
- The execution of your job is running in a different process (owstimer.exe)
- The job is called asynchronous, so you cannot define exactly when (at which second) the job is running
- If the service "SharePoint 2010 Timer" is not running on the machine, the job will never be executed
- Additionally (perhaps a bug): Sometimes, the breakpoints are not breaking, even if you attached the correct source to the correct process. In this case, you have to restart the "SharePoint 2010 Timer" service and everything works fine.
So to debug the job-processing, you have to follow these steps:
Here is a screenshot too about the attaching to a process, but this time, the owstimer.exe is selected:
This way, you can easily debug your SPJobDefinition code.
