Define a SQL Server Workload Group

Use the SQL Server Workload Group Editor in a SQL Server physical model to create a workload group and associate the workload group with a resource pool, and to define the resource policies for session requests. A workload group allows the aggregate monitoring of resource consumption and the application of a uniform policy to all of the requests in the group.

To define a SQL Server workload group

  1. Click Target - SQL Server, Workload Groups on the Model menu.

    The SQL Server Workload Group Editor opens.

  2. Select the workload group in the Navigation Grid that you want to define and work with the following options:

    Note: Click New New icon in property editors to create a new object on the toolbar to create a new workload group. Use the Enter filter text box to filter a very large list of workload groups to quickly locate the one that you want to define.

    Name

    Specifies the name of the workload group. You can change the name of the workload group in this field.

    Resource Pool

    Specifies the resource pool used by the workload group.

    Importance

    Specifies the relative importance of a request in the workload group.

    Generate

    Generates SQL during forward engineering. Clear the check box if you do not want to generate SQL.

  3. Click the General tab and work with the following options:
    Maximum Requests

    Specifies the maximum number of concurrent requests for the workload group.

    Request Maximum Memory Grant Percentage

    Specifies the maximum amount of memory that a single request can take from the pool.

    Request Maximum CPU Time

    Specifies the maximum amount of CPU time, in seconds, that a request can use.

    Request Memory Grant Timeout

    Specifies the maximum time, in seconds, that a query can wait for a memory grant (work buffer memory) to become available.

    Maximum Degree of Parallelism

    Specifies the maximum degree of parallelism (DOP) for parallel requests. Enter a value in the field.

  4. (Optional) Click the Comment tab and enter any comments that you want to associate with the object.
  5. (Optional) Click the UDP tab to work with user-defined properties for the object.
  6. (Optional) Click the Notes tab to view and edit user notes.
  7. Click Close.

    The workload group is defined and the SQL Server Workload Group Editor closes.
