The procedures described in the next four chapters are
based on the assumption that you will install the Tivoli® Data Warehouse database remotely from
the portal server.
There are two databases involved in IBM® Tivoli Monitoring:
- The Tivoli Enterprise Portal Server
database (or portal server database)
stores user data and information required for graphical presentation
on the user interface. The portal server database is
created automatically during configuration of the portal server.
It is always located on the same computer as the portal server.
- The Tivoli Data Warehouse
database (also called the warehouse database or data
warehouse) stores historical data for presentation in historical
data views. While it is possible for the warehouse database to be
located on the portal server (as
in the single computer deployment), it is best to create the database
on a remote computer to handle the warehousing needs of most production
environments.
No assumption is made about where you will install the
Warehouse Proxy Agents
and
Summarization and Pruning Agent.
Either of these agents may be installed on the same computer as the Tivoli Data Warehouse or on a
different computer:
- Installing the Warehouse Proxy Agent and Summarization and Pruning Agent on
the same computer as the data warehouse minimizes server deployments,
simplifies configuration, and eliminates network transmission overhead.
- If you install these components on different computers, ensure
that you have a high-speed network connection for best performance.
- In environments with more than one Warehouse Proxy Agent reporting
to the same hub monitoring server,
install each Warehouse Proxy on a separate computer.
