Presence Work Server
|Purpose:||Task execution (debug, schedule, on demand, SOAP)|
|Started By:||Heartbeat Server via Remote Program Call Server|
|License Type:||One license per server|
The Presence Work Server (also known as just the Presence Server) is the main Presence execution server. It's primary job is to Presence Tasks, and it does so in the following manners:
- Scheduled Task Execution
- On Demand Task Execution
- Task Debugging
- SOAP-invoked Task Execution
One or more Presence Servers can be installed on different machines (or Virtual Machines) to form a load balanced network. This allows you to scale up your Presence installation as your requirements grow.
The Presence Server uses a number of TCP/IP ports for internal communication. These are documented in the Server Ports page.
When multiple Work Servers are in place Tasks will be executed on an appropriate server based on Load Balancing settings.
