Splitting Workloads
Splitting a workload breaks it into one or more separate workloads recursively, creating new workloads from the existing workload classifications.
To split workloads
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 128. Note: If Teradata WA 15.00 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 15.0, 14.10, 14.0, 13.10, or 13.00, 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. |
Add New Classification |
Creates a new workload classification. |
Split |
Splits the source workload. The source workload’s classification is modified and a new split workload displays on the right panel. |
Advanced |
Activates the Copy, Move and Remove options. |
Copy |
Copies the selected classification criteria items from the source workload to the split workload. |
Move |
Moves selected items from the source workload to the split workload destination tree. |
Remove |
Removes the selected classification items from the split workload classification tree and move them back to the source workload tree. |
Accept |
Saves the changes and closes the Split Workloads dialog box. |
Cancel |
Discards the changes and closes the Split Workloads dialog box. |

Select individual clusters or select all clusters at the analysis parameter hierarchy (by clicking the ClientAddr check box to select all the clusters in that directory).
Each analysis parameter node (for example, UserName, AppID, and ClientAddr), contains cluster data that is either on the Included list or the Excluded list. Either include all clusters or exclude all clusters; it is not possible to do both.
10 Click Split.
The split workload is created and the existing source workload classification is modified. The name of the newly split workload contains the source workload classification’s name, suffixed with an SP1.
