Dropping a histogram template

You can drop a histogram template if you no longer require it.

Before you begin

To drop a histogram template, you require WLMADM or DBADM authority.

See Workload management DDL statements for more information about prerequisites.

You cannot drop the SYSDEFAULTHISTOGRAM histogram template.

You cannot drop a histogram template if it is being referenced by a service subclass, work action, or workload. You can view the service subclasses and work actions that reference a histogram template by querying the SYSCAT.HISTOGRAMTEMPLATESUSE view.

Procedure

To drop a histogram template:

  1. Use the DROP HISTOGRAM TEMPLATE statement.
  2. Commit your changes.
    When you commit your changes the histogram is removed from the SYSCAT.HISTOGRAMTEMPLATES view, and its bins are removed from the SYSCAT.HISTOGRAMTEMPLATEBINS view.
