services with the IBM Cognos Content Manager. During the normal operation of

IBM Cognos BI services, requests are load balanced across all available

services using a configurable, weighted round-robin algorithm to distribute

requests. You can tune the performance of IBM Cognos Platform by defining how

IBM Cognos Dispatcher handles requests and manages services.

Application tier: IBM Cognos Report Server

The main service that is responsible for application-tier processing is the report

or query service. IBM Cognos Dispatcher starts IBM Cognos Report Server

processes dynamically as needed to handle the request load. An administrator

can specify the maximum number of processes that these services can start, and

the minimum number of processes that should be running at non-peak times.

Application tier: IBM Cognos Content Manager

IBM Cognos Content Manager is the IBM Cognos Platform service that manages

the storage of the following client application data:

򐂰 Security settings and configurations

򐂰 Server configuration settings

򐂰 Packages

򐂰 Dashboards

򐂰 Metrics

򐂰 Report specifications

򐂰 Report output

You use IBM Cognos Content Manager to publish models, retrieve or store report

specifications, handle scheduling information and manage the IBM Cognos

security name space. IBM Cognos Content Manager maintains information in a

relational database that is referred to as the

content store database.
