13.5 Oracle9i Mobile Server
The Oracle9i Mobile Server is part of Oracle9i Application Server (AS). It works with native synchronization clients distributed with Oracle9i Lite databases. The 9i synchronization engine has the following features.If our application was created using the Oracle9i Lite Mobile Development Kit, the Mobile Server could automatically generate synchronization logic for the application.Oracle9i Lite supports synchronization over any TCP/IP-based network, including HTTP, CDPD, and 802.11b Wireless LAN. We may also add new transports by using the Mobile Server Open Transport APIs.The synchronization server provides rich controls over conflict resolution, data subsetting, and security settings.The Mobile Server supports asynchronous synchronization. During "rush hours," each device just submits the synchronization content in a queue and leaves. The server processes the queue when it is not busy. The client later retrieves updates from the server from another queue. This allows it to support a large number of mobile devices at a time.
The Oracle Mobile Server synchronization engine is also available programmatically through administration and clientside APIs. However, those APIs are available only in C/C++, not in Java yet. |
