Causes the object to save its state and propagate changes to all the computers in the server farm.
|Update()||Causes the service to update its state and propagate the changes throughout the farm. (Inherited from SPWindowsService.)|
|Update(Boolean)||Causes the object to save its state and propagate changes to all the computers in the server farm, optionally throwing an exception if the object already exists in the configuration store. (Inherited from SPPersistedObject.)|
Microsoft SharePoint Foundation uses optimistic concurrency to synchronize updates to persisted objects. You are prevented from corrupting data if you try to update your object on two servers at once (for example, through the timer service). However, because one of the updates might fail, you should avoid updating objects from an automated process.
