Trend analysis report shows no data.
Trend analysis uses the statistics in Space manager Repository. If no statistics available in Space manager Repository for the objects, trend analysis is not available for those objects as well.
Run Analysis thru Space manager GUI by following:
1. Instant Analysis
Instant Analysis can be opened from many of these points, including Object Properties, Chained Row Repair, the Sizing Worksheet, certain reports and Tablespace Maps. Launch methods consist of the Analyze button and the Instant Analysis shortcut menu option.
2. Collecting Statistics with Analysis Groups
Analysis groups consist of one or more objects for which statistics should be collected with the same options at the same frequency.
a. Go to Manage menu | click on New Analysis Group
b. Follow steps in the Analysis wizard
Once the statistics are collected into Space manager repository, then rerun the trend analysis report
