Space requirement estimates based on user-specified values
Standard space-estimation tools use IBM default DDL values for object attributes when calculating estimates.
In contrast, the Simple Space Estimation (SSE) feature allows you to replace those defaults with values that are specific to your objects. DASD MANAGER PLUS, Catalog Manager, and Change Manager support this feature.
For example, for a non-partitioned table space estimate, you can change the bolded fields on the panel displayed in Catalog Manager. SSE then estimates how much space will be required if you reorganize the table space. SSE displays estimates for the entire table space in the Estimated box on the right, and table-level estimates at the bottom of the panel.
For a description of each field that accepts user-specified values, see the online Help.
