Administer reliable web services

To configure a web service application to use WS-ReliableMessaging, you attach a policy set containing a WS-ReliableMessaging policy type. This policy type offers a range of qualities of service: managed persistent, managed non-persistent, or unmanaged non-persistent. WS-ReliableMessaging is an interoperability standard for the reliable transmission of messages between two endpoints. To administer WS-ReliableMessaging for an application, you take the following broad actions:

1. Attach a reliable messaging policy set (either a default policy set or one that we have created) to an aspect of the application (that is, application level or web service level). Policy sets define the reliability level (quality of service) and other configuration options to apply to your reliable messaging application.
2. Define the bindings for each attachment to a policy set that specifies a managed quality of service. That is, choose the service integration bus and messaging engine to use to maintain the state for the managed persistent and managed non-persistent qualities of service.

At any stage, we can set a property that configures endpoints to only support clients that use reliable messaging. This setting is reflected by WS-Policy if engaged.

If wer WS-ReliableMessaging application runs inside the web container and uses a managed quality of service, we can also use WS-ReliableMessaging to provide transactional recoverable messaging.

• Configure a WS-ReliableMessaging policy set.

  We can do this or using wsadmin. We can also configure WS-SecureConversation to work with WS-ReliableMessaging.

• Attach and bind a WS-ReliableMessaging policy set to a web service application

  We can do this or using wsadmin.

• Configure endpoints to only support clients that use reliable messaging.
• Provide transactional recoverable messaging through WS-ReliableMessaging.

Subtopics

• Configure a WS-ReliableMessaging policy set
  To configure a web service application to use WS-ReliableMessaging, you attach a policy set containing a WS-ReliableMessaging policy type. This policy type offers a range of qualities of service: managed persistent, managed non-persistent, or unmanaged non-persistent. Use the dmgr console to configure a policy set for reliable messaging.
• Attaching and binding a WS-ReliableMessaging policy set to a web service application
  To configure a web service application to use WS-ReliableMessaging, you attach a policy set containing a WS-ReliableMessaging policy type. This policy type offers a range of qualities of service: managed persistent, managed non-persistent, or unmanaged non-persistent. Use the dmgr console to attach the policy set to the application, and (for managed qualities of service) define bindings to a service integration bus and messaging engine.
• Configure endpoints to only support clients that use WS-ReliableMessaging
  By default, when a WS-ReliableMessaging enabled policy set is attached to an endpoint, the server supports clients that use reliable messaging and clients that do not use reliable messaging. In this version of the product, we can configure endpoints to only support clients that use reliable messaging.
• Providing transactional recoverable messaging through WS-ReliableMessaging
  If your WS-ReliableMessaging application runs inside the web container and uses a managed quality of service, we can use WS-ReliableMessaging to provide transactional recoverable messaging.
• WS-ReliableMessaging - dmgr console panels
  Links to topics that describe the contents of the dmgr console panels used to configure and operate WS-ReliableMessaging. Each topic gives details of the purpose and use of a panel, the dmgr console navigation path to the panel, and the values that we can set in each field of the panel.
