IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
The data warehouse is remote from the portal server
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:
- Install 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.
