SharePoint : SPJOBLockType

Specifies the lock type for a given timer job definition.


There are 3 Locks available..
  1. SPJobLockType.None -- if you set it none, the instance will run in all the available servers in the Farm (e.g. Application Server Timer Job)
  2. SPJobLockType.ContentDatabase – this will cause 3 instances to be running in each of the Web-Frontends.in short, it’s almost the same as the Job one, meaning that it only runs one server.
  3. SPJobLockType.Job – this will cause only one instance of the job to run on any of the front-end servers. (Note: it is possible to see multiple instances listed in the Job Status .. but if you look at the time it was last run.. only one would have run lately.
