Adding Qualities of Service (QoS) qualifiers

QoS qualifiers can be specified for implementations, interfaces and partner references in the Properties view.

See "Quality of service: Qualifiers" topic under related concepts for more information on qualifiers. See "Processing events in a sequence" for detailed instructions for adding event sequencing qualifiers.

Follow these steps to add qualifiers:

  1. Select an artifact. Qualifiers can be set on interfaces, partner references, or implementations.
  2. In the Properties view, click the Details tab to set qualifiers on interfaces and references. Click the Implementation tab to set qualifiers for the component's implementation.

    Here is an example of the qualifiers page to for a partner reference:

    Here is an example of a qualifiers page for a mediation flow implementation:

  3. If required, expand the tree in the properties to select the element. Qualifiers are displayed in its own page. Click the Qualifiers tab to show the settings.
  4. In the Qualifier page, use the Add and Delete buttons (in the top part of the page) to add and remove qualifiers for the selected element. Qualifiers can be inherited from parent elements. Listed qualifiers in grey means that the qualifiers are inherited. You can click Override to override the parent qualifier with a different setting. Selecting the qualifier in the top part of the page will display its details in the lower part of the Qualifiers page. You can drag the separator bar between these two sections of the Qualifier page to expand the area that you want to view.

The following Properties view shows two qualifiers for the DelayedServicePortTypePartner reference; the Reliability qualifier is inherited from the References and the Suspend Transaction qualifier is specified for this reference:
