Overview of Store-and-Forward Messaging for Mobile Web Client Architecture

The architecture of Store-and-Forward Messaging for Mobile Web Client consists of Siebel Server elements, Siebel Mobile Web Client elements, and IBM MQe queueing software, in the context of a Siebel Business Application deployment that includes Siebel Remote.

Table 3 specifies the kinds of data synchronization that are handled by Store-and-Forward Messaging, and the kinds of data synchronization that are handled by Siebel Remote.

Figure 3 shows the components that are used to transmit messages from the Siebel Server and receive those messages on the Mobile Web Client using Store-and-Forward Messaging.

Figure 4 shows the components that are used to transmit messages from the Mobile Web Client and receive them on the Siebel Server using Store-and-Forward Messaging.

Figure 5 shows the mixture of Siebel Remote components and Store-and-Forward components that are used to transmit all file attachments from the Siebel Server and receive them on the Mobile Web Client.

Figure 6 shows the mixture of Siebel Remote components and Store-and-Forward components that are used to transmit large file attachments from the Mobile Web Client and receive them on the Siebel Server.

Store-and-Forward architectural elements are described in the following paragraphs. For information about Siebel Remote elements, see Siebel Remote and Replication Manager Administration Guide.

RTSDispatcher

This server component retrieves transactions from the transaction log and creates Store-and-Forward work items that identify which Mobile Web Clients will receive Store-and-Forward messages.

RTSExtractor

This server component extracts the needed data from the database and creates the appropriate Store-and-Forward messages.

RTSSender

This server component sends Store-and-Forward Messages to the designated Mobile Web Clients by means of IBM MQe, and then deletes the associated work item.

IBM MQe

IBM WebSphere MQ Everyplace (MQe) provides a secure transport layer for transmitting Store-and-Forward messages over wired and wireless networks. For more information about MQe, see About IBM WebSphere MQe.

RTSQApplier

This server component retrieves messages from the SMQ Receiver server component and applies the updates that are contained in the messages to the Siebel Server's database.

SMQ Receiver

This server component receives Store-and-Forward messages that Mobile Web Clients send by means of the transport service. SMQReceiver invokes the RTSQApplier component and passes the message to that component.

RTSClient

This architectural element is a background process on the Mobile Web Client. It performs the following functions:

• Sending database updates from the Mobile Web Client to the Siebel Server as Store-and-Forward messages
• Receiving Store-and-Forward messages from the Siebel Server and applying the database changes in the messages to the Mobile Web Client's local database.
