Combine playback (refresh) and synchronization (sync) parameters to control the way that data is cached in the consolidated database (CDB) in Unwired Server, and filtered and returned to a device application.
Mobile business object (MBO) playback and sync parameters affect the data returned from the enterprise information system (EIS) to the Unwired Server cache, called the consolidated database, or CDB, as well as filtering the data before it is returned to the device application.
| Parameters | Result |
|---|---|
| Playback=none sync=none |
The entire table is downloaded to the device. For example: select * from sampledb.dba.customer |
| Playback=none sync=region |
Only customers of a specific region are downloaded to the device. Typically, region is paired with a personalization key. For example, a sales representative living and working in the western region is interested only in customers from that region, which can also be set as the default value: select cust_id, cust_name, region from sampledb.dba.customer where region=@OP["region"="western"] |
| Playback=region sync=region |
Occurs if customer playback requires a region parameter (which is also the sync parameter). This scenario is more likely for Web service and SAP MBOs than for database MBOs. |
| Playback=username, password sync=region |
Playback only for a particular user (with proper authentication) using the username and password parameters, but synchronize based on the region: select cust_id, cust_name, region from sampledb.dba.customer where region=@OP["region"="western"], for user A. |
