Handheld Synchronization

A Handheld synchronization server component run on the Siebel application server can accept concurrent synchronization requests from multiple synchronization clients. When connecting directly to a server, the Siebel Handheld Sync client synchronizes its data directly to a server database. Companion Sync allows users to synchronize the Handheld Database to the local database on a companion PC device and invokes Siebel Remote to synchronize a local database with the server database.

In Direct Server Sync mode, the Siebel Handheld Synchronization client uses the HTTP(S) protocol over a network connection to communicate with the handheld synchronization server. Users should configure their handheld devices for communication over the desired network.

A companion synchronization server runs on a companion personal computer with a Mobile Web Client installation and supports synchronization with a data source specified in a client configuration; the database resides on the companion PC.

Companion Sync

Companion Sync allows users to synchronize the Siebel Handheld application and database with a Siebel Remote database on a Mobile Web Client.

Microsoft ActiveSync is used to connect the handheld device and the companion PC through a serial or USB connection. The user launches Siebel Handheld Sync from companion PC or the device. The user can change the default filters using Siebel Handheld Sync.

Direct Server Sync

Direct Server Sync allows users to synchronize their Siebel Handheld application and database directly with the Siebel server. The user connects the handheld device to the Siebel application server through a network connection that uses the HTTP protocol. The connection runs through a IIS Web server to the application server, where the Sync server components are installed and running.

Direct Server Sync via Proxy

Direct Server Sync via Proxy (DSSvP) allows users to synchronize their Siebel Handheld application and database directly with the Siebel server. The user connects the handheld device to the Siebel application server through ActiveSync and the network connection established by the companion PC. The connection runs through a IIS Web server to the application server, where the Sync server components are installed.
