Define DB2 LUW Thresholds

You can use DB2 LUW thresholds to detect resource misuse or the beginning of system overload. Use the DB2 LUW Thresholds Editor to specify threshold properties.

Note: This topic applies to DB2 for LUW versions 9.5 and 9.7 only.

To define a DB2 LUW threshold

  1. Right-click Threshold in the Model Explorer and select New.

    A new threshold with the default name appears.

  2. Right-click the newly created threshold and select Properties.

    The DB2 LUW Threshold Editor opens.

  3. Work with the following options:
    Name

    Specifies the name of the threshold.

    Type

    Specifies the domain the threshold applies to. Select from the drop-down list; valid values are Database, Service Class, and Workload.

    Scope

    Specifies the threshold scope. Select from the drop-down list. Valid values are Database, Database Partition, or Workload Occurrence.

    Enabled

    Indicates whether or not the selected threshold is enabled.

    Generate

    Specifies whether or not to generate DDL for this object during Forward Engineering.

  4. Work with the following options on the General tab:
    Workload

    Specifies the workload for which you are defining threshold.

    Service Class

    Specifies the service class for which you are defining threshold.

    Threshold Predicate Type

    Specifies the threshold predicate type. Select from the drop-down list.

    Threshold Value

    Specifies a value for the threshold type.

    Threshold Collect Activity Data Type

    Specifies the activity data that the applicable threshold collects. Select from the drop-down list.

    Collect Activity Data for Partition Type

    Specifies the level at which you want to collect data about each activity that exceeded the threshold. Select from the drop-down list; valid values are Coordinator Partition and All Partitions.

    Threshold Action Execution Type

    Indicates the action executed when the threshold is exceeded. Select a value from the drop-down list. Valid values are Stop Execution, Continue, or Remap Activity.

  5. Click the Comment tab and enter any comments you want to associate with the threshold.
  6. Click the UDP tab to work with user-defined properties for the threshold.
  7. Click the Notes tab to view history information and view or edit user notes.
  8. Click Close.

    The DB2 LUW Threshold Editor closes.
