Frequency based bucketing counts the number of members in each bucket, and then
determines the buckets that exceed the maximum bucket frequency number.
About this task
Use this procedure to enable frequency based bucketing on a particular bucketing
group. You must be in the Configuration perspective.
Note: If your deployment uses synchronous entity management, then dynamic frequency based bucketing
(DFBB) is not possible. For more information about synchronous and asynchronous entity management,
see
Entity managers.
Procedure
- In the toolbar, select Advanced Interface from
the Editor interface list.
- In the configuration editor, select the Algorithms view.
- Select the bucketing group.
- In the Properties view, set the Maximum
bucket size property in the Properties view to a value
greater than 0. If Maximum bucket size is greater
than 0, Maximum attribute tokens must be greater
than Minimum attribute tokens.
- Redeploy the algorithm to the InfoSphere® MDM instance.
- Generate your frequency files by running the Generate Frequency Stats
(mpxfreq) utility. Set the Generate frequency tables for
frequency-based bucketing option. The output of mpxfreq must be
copied into the project from InfoSphere MDM through the
Jobs view by running the Get job results action on the successful Generate
Frequency Stats (mpxfreq) job.
- Deploy the configuration to the InfoSphere MDM instance.
