Regional Node
A regional node is a separate Siebel Enterprise Server that includes a Siebel database, Siebel Servers, and Siebel File System that support a set of connected users. The set of registered users at the regional node determines the set of connected users.
Each regional node is a child of a parent node. A parent node is another Siebel Enterprise Server that is the headquarters node or another regional node. A regional node contains a full copy of data or a subset of data from the parent node. This copy includes database records and file attachments. A regional node is typically geographically separated from the headquarters node, but this configuration is not required.
Replication Agent
The Replication Agent server component runs on the Siebel Server on the regional node. To keep data current at these locations, it periodically synchronizes the regional database with the parent database. Replication Agent runs as a service mode task, which is a type of task that runs continuously after it starts.
