It is usually worthwhile to take a few minutes after you have
created an Alphablox cube to ensure that the measures, dimensions, and levels
are defined correctly. If you find any errors, you can easily correct them.
To do a review on an Alphablox cube, perform the following steps:
- Log into the Alphablox home page as the admin user or as a user
who is a member of the administrators group.
- Click the Administration tab.
- Click the Cubes link.
- Select the Alphablox cube from the list of cubes and click the Edit button.
A page showing the Edit Alphablox Cube General tab appears.
- Verify that the data source specified in the Relational Data Source text
box references the desired relational database. You might need to check the
settings for the data source on the Data Sources administration page.
- Before attempting to start the Alphablox cube, verify that Enabled is
selected next to the Alphablox Cube Name text box. If it is not enabled,
you will see an error message when attempting to start the cube.
- Verify that your measures are properly created:
- Click the Measures node to verify that the table specified in the Measures
Fact Table text box is the correct table in the relational schema, the
name is spelled correctly, and the name is a fully-qualified name.
- For each defined measure, check that the desired aggregation is specified
in the Expression text box.
- Verify that all the desired dimensions have been correctly defined, and
that the names are correct. For each dimension, check the following:
- Verify that you had added any required fact table join and dimension joins,
and that the expressions are correct.
- Verify that the levels are correctly specified and appear in the correct
order. The first level should be the most summarized level, and each successive
level should be the next level down in the hierarchy. For example, if the
hierarchy for the Time dimension is Year, Month, Day,
then Year should be the first level, followed by Month , followed
by Day .
- Verify that any attributes that you have defined are correct, including
the expected names and expressions.
- Click the Schedule tab and verify that all the settings are the
way you want them.
- Click the Tuning tab and verify that all the settings are the way
you want them.
After completing this review of your Alphablox cube, you can
start the cube. For details on starting an Alphablox cube, see Starting, stopping, and rebuilding cubes.
