SSSE Architecture

Figure 2 illustrates the SSSE Architecture. Each SSSE user's machine interacts with the Siebel database and the Microsoft Exchange Server Host. The communications that occur between the Siebel Database and the PIMSI Engine and PIMSI Dispatcher servers are separate from the communications that occur between the Siebel Database and individual SSSE user machines. The Exchange Connector Host acts as an intermediary for communications between PIMSI Engine and the Microsoft Exchange Server Host.

If your implementation includes firewalls between SSSE components, you may need to open specific ports in the firewall to allow the various parts of the implementation to communicate with each other. For more information about using SSSE with firewalls, see Configuring Firewalls for Use With SSSE.
