Cisco Cisco Unified IP Interactive Voice Response (IVR) 8.0(1) 管理员指南

This section provides information about control center terminology.

Cluster. A Unified CCX cluster (often referred to as cluster in this manual) 
consists of one or more servers (nodes) that are running Unified CCX 
components in your Unified CCX deployment. If you deploy Unified CCX 
components on a single server, the Unified CCX cluster consists of that 
server. If you deploy Unified CCX on multiple servers, the cluster includes 
the Unified CCX server and standby servers on which you installed Unified 
CCX. The Unified CCX cluster supports up to two Unified CCX servers, one 
designated as the active Unified CCX server and the other designated as the 
standby Unified CCX server for high availability purposes.

Support for High Availability and remote servers is available only in 
multiple-server deployments.

Cluster profile. The Unified CCX Administration web page (home page) 
displays information about the cluster profile. A cluster profile includes data 
relating to the Unified CCX servers, components, and licenses installed in a 
cluster. 

Node (server). A computer that belongs to a cluster.

Active Server. The active server provides all system services and resources. 
You can deploy one active server in each Unified CCX subsystem. If the 
active server fails, the Unified CCX subsystem automatically fails over to the 
standby server (see 

Standby Server. You can deploy up to two servers in each Unified CCX 
system for high availability—one active server (master) and one standby (not 
active) server. With high availability, if an active server becomes 
unavailable, the standby server immediately and automatically becomes the 
active server (see
