Spotlight on DB2 6.9.3 - Getting Started Guide

Tablespace Analysis drilldown Ranges tab

The Ranges tab on the Tablespaces drilldown shows how ranges are defined for range partitioning in DMS tablespaces. When an aggregate tablespace row is selected, the tab shows partitioning information for a tablespace across all database partitions. When the row for an individual tablespace is selected, the tab shows partitioning information for the partition on which the tablespace is defied.

Note: Information in the Ranges tab applies only to DMS tablespaces. It does not apply to SMS tablespaces.

Columns in the Ranges tab

All columns available for the Ranges tab are listed below in alphabetic order. Initially, the tab contains Spotlight's default column selection. You can choose which columns to display and organize them in any order from left to right using the Organize Columns function. This can be selected from the right-click menu for column headers.
