Changing Synchronization Parameters

Synchronization parameters let an application change the parameters that retrieve data from an MBO during a synchronization session.

Note: This topic is not applicable for DOE-based applications.

The primary purpose of synchronization parameters is to partition data. Change the synchronization parameters to affect the data you are working with (including searches), and synchronization.

When a synchronization parameter value is changed, the call to save automatically propagates the change to the Unwired Server.

Consider the Customer MBO that has a cityname synchronization parameter. This example shows how to retrieve customer data corresponding to Kansas City.

CustomerSynchronizationParameters *sp = [Customer getSynchronizationParameters];
sp.size = 3;
sp.user = @"testuser";
sp.cityname = @"Kansas City";
[sp save];
while ([SUP101_SUP101DB hasPendingOperations])
    [NSThread sleepForTimeInterval:0.2];

Note: The Sybase Unwired Platform server will not send MBO data to a device if an MBO has synchronization parameters defined, unless the application client code calls the save method. The next synchronize call will retrieve data from the server. This is true even if default values are defined for its synchronization parameters.
