Synchronization
The Synchronization property indicates whether the runtime has the latest configuration for an object. An object is shown as Out of Sync when the runtime is not running the latest configuration and otherwise is shown as In sync.
For example, if you modify a port number of a node after its installation, the runtime would have the older port number, and node will show as Out of sync. To sync the runtime node with the latest configuration, you must execute one or more actions.
Only the properties that change the behavior of an object at runtime are tracked using the synchronization flag. For example, modifying an object's permissions does not make the object go out of sync because permissions are used only by Administrator and are not sent to the runtime.
Administrator displays only whether an object is in sync or not. Hover over the Out of Sync text to see the change that caused it to have a different configuration than what is in the runtime. For example if you distribute the application to a second node the hover text will say Distribution Config. If more than one type of change is causing the object to be out of sync, all of them will be displayed separated by semicolons. You may need to refresh the master list to observe a change to the synchronization state or reason. Clicking the Out of Sync text opens a dialog box Synchronization Details that provides more information about the changes.
