Start Query Studio in Preview Mode

You can configure Query Studio to start in preview mode. Users can then create or modify reports without retrieving actual data from the database. Instead, simulated data is shown.

If you later upgrade IBM Cognos 8, you must reapply this configuration.
Steps

1. Using IBM Cognos Configuration, stop IBM Cognos 8.
2. Rename the c8_location\templates\ps\async\system.xml.sample file to
system.xml.
Tip: To restore the regular mode, rename the
c8_location\templates\ps\async\system.xml file to system.xml.sample.

3. Using IBM Cognos Configuration, start IBM Cognos 8.
