Splitting a workload breaks it into one or more separate workloads recursively, creating new workloads from the existing workload classifications.

1 From the Candidate Workloads tree, right-click on the workload you want to split.

The shortcut menu displays.

2 Select Split.

The Split Workloads dialog box appears.

The following table describes the Split Workloads dialog box options.

 

Options

Description

Workload #1

Displays the source workload name. Below the name is its classification.

Include

Lists the classifications to be included before splitting the workload. Select the check box of the item to be included for the split.

Exclude

Lists the classifications to be excluded before splitting the workload. Select the check box of the item to be excluded for the split. The exclusion limits the split to requests that include the excluded object type. For more information, see “Classifying by Excluded Objects for Splitting and Merging Workloads” on page 139.

Note: If Teradata WA 15.10 is connected to Teradata Database 12.00, the Include or Exclude options can be used for each classification type. If the system is connected to Teradata Database 13.00 and higher, both Include and Exclude options can be used for each classification type.

Workload #2: (Evaluated First)

Displays the destination workload name. The destination workload name is created by adding the suffix _SP1 to the source workload name. Below the name is its classification.
