Fine-tune device application and Unwired Server performance by defining a cache update policy for mobile business object operations.
Setting a cache update policy for mobile business object (MBO) operations gives you more control of both Unwired Server interactions with the enterprise information system (EIS) to which the MBO is bound, and Unwired Server cache database (CDB) updates. Fine-tuning these interactions and updates improves both Unwired Server and device application performance.
While this type of bulk-fetch and CDB caching are effective in reducing the number of interactions required with the back-end EIS, and work well in some other cases (where MBO data is occasionally updated in the back-end), performance suffers if changes are initiated from Unwired Server (by way of MBO operations), or if changes are frequent.
A cache update policy provides alternative methods of updating the cache at finer granularity, which improves performance.
When an MBO operation is called, its cache update policy determines how operation results are applied to the CDB.
