Modify common and policy properties for cache groups.
Each mobile application project contains a Cache Groups folder that contains all cache groups for the mobile business objects (MBOs) belonging to that project.
-
In WorkSpace Navigator, expand the mobile application project to access the Cache Groups folder.
-
Expand the Cache Groups folder, right-click the cache group you want to view or modify, and select Properties.
-
In the left pane, select either the Common
or Policies
tab, and view or modify:

Policies

- On Demand – application logic determines the refresh schedule. You can also use a Cache interval to trigger a cache refresh.
- Scheduled – On demand and Scheduled are mutually exclusive. The cache is refreshed when a scheduled task executes.
- Never – the cache never expires. This interval applies to both On demand and Scheduled policies.
- Cache interval – for use with On demand or Scheduled, allows you to associate an interval with the cache group. If an application tries to synchronize:
- Before the cache interval expires – the client application receives the data currently in the consolidated database (CDB).
- After the cache interval expires – the CDB is refreshed from the enterprise information system (EIS), and the client synchronizes with the data in the CDB.
If the cache interval is set to zero, each device-initiated synchronization refreshes the entire cache prior to synchronization. While this ensures the device receives up-to-date EIS data, it is costly in terms of resources.
A Scheduled cache policy does not support a zero interval.
