IBM Tivoli Monitoring, Version 6.3 Fix Pack 2
Warehouse Summarization and Pruning Agent
The Summarization and Pruning Agent is a unique agent that performs the aggregation and pruning functions for the historical detailed data on the Tivoli Data Warehouse. The Summarization and Pruning Agent has advanced configuration options that enable customization of the historical data storage. One Summarization and Pruning Agent manages the historical data in the Tivoli Data Warehouse.
The Summarization and Pruning Agent can be placed on the Tivoli Data Warehouse database server to minimize network transmission delay during its processing. If the Summarization and Pruning Agent is placed on a separate server, ensure that it connects to the database server with a high-speed network connection of 100 Megabits per second or higher. For large environments, the database server must have at least four processors and a large number of disks, with maintenance by a skilled database administrator.
Performance enhancements were added into the Summarization and Pruning Agent for the IBM Tivoli Monitoring V6.2.1 release. Some of the enhancements require a new database schema. The warehouse will function without the schema changes, but will not take advantage of some of the performance improvements. For the enhancements that do not require a new schema, there are minor database changes that are documented in Schema Publication Tool. In a new Tivoli Monitoring environment, the warehouse database schema will be created using the new schema. If the Tivoli Monitoring V6.3 environment was updated from a release that used the old schema, the database will continue to use the old schema and will not benefit from the improvements. To take advantage of the performance improvements in an upgraded environment, you will need to create a new warehouse database with a new schema. If desired, you can migrate the data from your old warehouse database into your new warehouse database.
