Configuration Management Service (CMS)
Real-Time Data
The real-time client process on the Distributor AW keeps the real-time data in the
local database up-to-date. It receives real-time data from the real-time server
approximately every ten seconds. Old real-time data is constantly overwritten by
new real-time data.
For information on how real-time data is delivered, see Chapter 2, “Fault
Tolerance.”
Configuration Management Service (CMS)
In integrated environments, the Configuration Management Service (CMS)
coordinates the configuration of objects common to both ICM software and to
application instances such as Cisco E-Mail Manager and Cisco Collaboration
Server. CMS also authenticates agents when they log in. Common objects are
stored both in the application instance local database and the ICM central
database. The copy of the data in the ICM central database is used for integrated
reporting and for authentication of agents. The copies of the data in the
application instance databases is used for application specific reporting and for
application operation.
CMS includes the following components:
• A set of client libraries that reside on the application instance system and are
called by the application.
• A service process that runs on an ICM Distributor.
The server process reads configuration data from the Distributor database and
writes configuration data to the ICM via the Central Controller API (CCAPI).
The CMS client library communicates with the CMS server process using a
message bus. Figure 3-2 shows the CMS integrated architecture.
