7 ADF Mobile Overview Visual Declarative Rapid Reuse Familiar Develop once, and deliver mobile optimized content to all devices. Mobile Browser Mobile Client

8 Richness of User Interaction Oracle ADF Mobile Platform ADF Mobile Browser ADF Mobile Client Delivers a rich mobile web experiences through AJAX and Web 2.0 technologies. UI rendering degrades gracefully to deliver HTML content to a wide set of consumer devices with basic HTML browsers. Native (Full Java Clients) Make business data available regardless of network connectivity. Deep integration with device services HTML (HTML Mobile Browser) AJAX (Smartphone Mobile Browsers) Device Service Access & Offline Support

20 Agenda <Insert Picture Here> Einführung Mobile Browser Mobile Client Mobile Database

21 Database Lite s Basic Components (Mobile Server and Client) Client Mobile Server Oracle Database Server Database Lite product Device / Sync Client OC4J or WLS Users Application ODBC / JDBC SQLite BDB Mobile Server MGP Oracle Database Server Database Lite product MGP = Message Generator Process

22 Key Synchronization Features Bi-directional Synchronization Oracle Database Lite supports upload and download of data during Synchronization. Synchronization can be customized to allow only upload. Synchronization can be customized to allow only download. Publish-Subscribe Model Developers can publish data subsets independent of their subscription by users Multi-platform Support Synchronization can be supported from multiple client platforms. Synchronization can be supported with Mobile Server running on multiple platforms. Selective Synchronization Full base table synchronization or subset of base tables

23 Key Synchronization Features Conflict/Error Detection and Resolution Database Lite provides built-in conflict resolution capabilities via the Server Wins/Client Wins rules. Conflict resolution can be further customized by customizing synchronization. Mobile Server administrator can further manage conflicts. Synchronization Styles Automatic Synchronization allows Database Lite to invoke synchronization in the background. Manual Synchronization allows user or application to control synchronization timing. Software Management and Distribution Database Lite synchronization supports software distribution and updates.

29 Performance Perspective Client Apply/Compose Network transfer/latency Mobile Server Processing MGP MGP Apply MGP Compose Total Response Time Usually the performance of the client database is not an issue The speed of the network is always a large element of the total response time, application design should ensure that client subscriptions are fast refreshed when possible to minimize network requirements. Mobile Server Processing is a affected by the total number of concurrent users, (MAX_Concurrent parameter in webtogo.ora parameter file) and memory tuning of JVM. MGP is usually the most resource intense process and the Compose Phase of MGP will constitute the larger part of total MGP time. This is affected by the Oracle Database instance and classic SQL tuning and instance tuning can make tremendous differences in the performance of MGP. Especially difficult issues involving elongated MGP time can best be diagnosed using the Consperf tool.
