Optimization
You must configure the Dataset Attributes Database feature to optimize performance. Otherwise, the amount of data that you collect might consume excessive system resources. See Configuring the Dataset Attribute Database feature and also Optimizing data collection for the Dataset Attributes Database feature.
For example, you can optimize configuration of the following behaviors:
- Exclusion of specific SMS Storage Groups and Volumes
- Collection interval
- Number of items listed in the Summary reports
- Inclusion of catalog data
Note: Data collected for the Dataset Attributes Database is maintained in an in-memory data space for high-performance access. The data is not saved to disk, except for those Summary tables that have been configured for historical collection. For this reason, following a restart of the Tivoli® Enterprise Monitoring Server address space, the database must be rebuilt by initiation of a collection cycle, either manually or at a scheduled time.
