Cognos 8 Business Intelligence (BI) V8.4 on AIX best practices

Cognos 8 Content Manager
Content Manager is the Cognos 8 service that manages the storage of customer application data,
including security, configuration data, models, metrics, report specifications and report output. Content
Manager is needed to publish models, retrieve or store report specifications, handle scheduling
information and manage the Cognos name space. Content Manager maintains information in a relational
database that is referred to as the content-store database. A minimum of one Content Manager service is
required for each Cognos 8 implementation. Content Manager performance can benefit from the
availability of high-speed RAM resources and typically requires one processor for every four Report
Server processors.
Cognos 8 data-source performance
Query performance is typically bound to the performance of the server that hosts the data source for
Cognos 8, which can access many data sources including relational and OLAP sources. Relational data
source that are tuned to meet the requirements of Cognos 8 BI reports naturally perform better than those
that are not. Relational database-management systems (RDBMSs) should be monitored and tuned by an
experienced database administrator to achieve optimum database performance.
Cognos 8 BI deployment practices
Server components within all three tiers can easily scale to meet a variety of very large BI processing
requirements. At the Web tier, Cognos 8 Gateway instances are comparably lightweight and can,
therefore, handle large user loads. You can also deploy multiple Gateway instances to meet requirements
for additional user load, server availability or other service-level agreements (SLAs). At the application
tier, both the Cognos 8 Report Server and Content Manager components can scale to meet application-
processing requirements. You can deploy multiple Content Manager instances in an active or standby
configuration to provide high availability. Content Manager Server hardware can also scale vertically to
provide increased throughput. Cognos 8 Report Server performs the heavy lifting within a Cognos 8
server platform. You can deploy multiple Report Server instances to meet the processing requirements of
very large applications and user populations. Report Server performance is tied to overall system
performance and, therefore, can be affected by processor clock speed and I/O performance.
The first step to creating a proper Cognos 8 BI environment begins with a successful installation. Use the
Cognos 8 BI Installation and Configuration Guide to lead you through the installation and initial
configuration process. Selecting the appropriate deployment options comes next. The previous section
provides a brief introduction to deployment suggestions for Cognos 8 BI. For more detailed information
about Cognos 8 architecture and server deployment options, read the Cognos 8 BI Architecture and
Deployment Guide (http://support.cognos.com, navigate to the Documentation page and select the
Cognos 8 Business Intelligence 8.4 product). In addition, useful information about tuning the Cognos 8
server platform is available in chapter 7 and chapter 8 of that guide.
After you have Cognos 8 BI installed and tuned, you can use the built-in tools to monitor performance.
For information related to monitoring Cognos 8 system performance metrics by using Cognos 8
Administration Console, read chapter 4 of the Cognos 8 BI Administration and Security Guide
(http://support.cognos.com, navigate to the Documentation page and select the Cognos 8 Business
Intelligence 8.4 product).
