Configuring a Cache Group

Select and configure a cache group. The cache is part of the SAP Mobile Server cache database (CDB) that is used to store data that is uploaded and downloaded from EIS servers and mobile clients during synchronization.

• MBO Data in the CDB
  A data cache is a copy of MBO data that is stored in a specific area of the cache database (CDB). It is used as the data repository for replication and messaging MBOs that are deployed to SAP Mobile Server. "CDB" and "cache" and "MBO data" can sometimes used interchangeably, even though the CDB includes runtime data as well.
• Configuring On Demand Cache Group Properties
  Specify the duration of cache data validity by configuring SAP Mobile Server updates to mobile business object (MBO) data for an on demand cache group.
• Configuring Scheduled Cache Group Properties
  Specify the duration of cache data validity by configuring SAP Mobile Server updates to mobile business object (MBO) data for a scheduled cache group.
• Online Refresh Policy
  MBOs that use an Online refresh policy indicates that the MBOs are to be used only in Hybrid App applications where access to real-time enterprise information system (EIS) data is required (cache validity is zero).
• DCN Refresh Policy
  The cache refresh and schedule options are disabled for DCN (data change notification) policy, since data never expires and is not refreshed based on client demand or a schedule.
• EIS Managed Refresh Policy
  MBOs that use an EIS managed refresh policy indicates that the enterprise information system (EIS) initiates the connection to SAP Mobile Server to retrieve updates.
• Purging the Synchronization Cache Manually
  You can manually purge the synchronization at the package level.
