Performance
-By distributing load to unused resources minimizes hardware bottlenecks
Without the maintenance overhead of Resonate
-Resonate Central Dispatch is no longer supported as of Siebel 7.7
-Availability
If a load-balanced component becomes unavailable on one server, it can still be accessed through other load-balanced servers
-Security
Simple firewall configuration – 1 VIP/Vport only
Allows change of port used (I.e. HTTP Tunneling)
Round-robin through SWSE naming directory
Load balance by number of running tasks of OM instances
Listen to both static and configurable port
Support SISNAPI reconnect out of box
-When to Use
When all destination servers are of the same capacity
When customer does not want to purchase a HTTP 3rd Party load balancer

Manages network connections to the application servers
Requests a new network connection for each new user session
Connection is generally persistent, until processes terminated at either end points or SISNAPI connection timeout
-Contains two layers
Web framework layer –interacts with web client infrastructure
Session manager layer – manages SISNAPI connections to the application server
Siebel-Provided load balancing logic resides in the Session Manager layer

9. Siebel File System
-The Siebel File System consists of a shared directory that is network-accessible to the Siebel Server and contains the physical files used by Siebel clients. To gain access to files, web clients connect directly to the appropriate Siebel Server to request file uploads or downloads. The Siebel Server then accesses the Siebel File System using the File System Manager (FSM) server component. File System Manager will process these requests through interaction with the Siebel File System directory.
-When using Siebel Mobile Web Client in connected mode (also known as the Dedicated Web Client), you may want to connect directly to the Siebel File System without going through the File System Manager
