DataBindings.cpx Properties: Synchronization Mode
Note that the trade-off for the Immediate mode is that, in some circumstances, errors such as a database problem may surface mid-way through a page rendering. However, this is a very rare scenario. Batch mode is better suited to applications where the BC runs on a separate tier other than the application and you need to reduce the traffic between them. The synchronize mode property was set to ‘batch’ in 10.1.3.
