Overview of Deployment for the Siebel Handheld Application Client

This topic provides an overview of important factors to consider when planning a Siebel Handheld application deployment using Direct Server Synchronization (DSS). One aspect of successful planning and execution of a Handheld application deployment using DSS is to understand hardware and network requirements. While these factors are generally applicable to all deployments, there are unique aspects to each customer configuration and implementation strategy. Therefore, it is highly recommended that customers conduct detailed configuration, sizing, and production readiness reviews with Siebel Expert Services. This is especially important for complex deployments, such as those supporting large numbers of users over wide geographic areas.

You can also improve the performance and scalability of DSS deployments by working with the Siebel application server component parameters. For more information about the Siebel application server, see Optimizing Siebel Server Process Management for Direct Server Synchronization.

NOTE:  The recommendations in this chapter are general ones and are intended to raise your awareness of the key factors in Siebel Handheld application synchronization, performance, and scalability. These factors must be confirmed for your actual environment, and the usage patterns in your enterprise must be taken into consideration.

Siebel Server Topology Overview   

The diagram in Figure 4 shows the servers and components that are required to deploy Direct Server Synchronization for a Handheld application. The components are the Siebel Handheld application database, Siebel Server, Siebel Web engine, and Siebel Handheld application. The synchronization components are the synchronization engine for the Siebel Handheld application which resides on Siebel Server, and the Siebel Handheld Synchronization Client which resides on the Siebel Handheld application.

Recommended Hardware and Network Configuration

There are many factors to take into account when designing and implementing your server and network hardware and architecture, and sizing your Siebel Handheld application database. The critical factor in sizing the implementation for a Siebel Handheld application is the expected peak synchronization load. Specific Handheld application variables to consider in calculating this load are: the number of concurrent users, number of transactions, and size of the data file. These variables must be considered within the context of the hardware specifications, including memory and processor speed.
