WS-ReliableMessaging policy binding
To configure a web service application to use WS-ReliableMessaging, you attach a policy set that contains a WS-ReliableMessaging policy type. This policy type offers a range of qualities of service: managed persistent, managed non-persistent, or unmanaged non-persistent. The managed qualities of service, managed persistent and managed non-persistent, are supported by the service integration bus. Use this page to select the bus and messaging engine to use for the reliable messaging protocol state.
- (This is the default binding for client and provider policy set attachments within WebSphere® Application Server Version 6.1 applications, and attachments to service applications that are deployed to a Version 6.1 server.)
- (This binding is used for the specified provider policy set.)
- (This binding is used for the specified client policy set.)
- You only have to specify a binding to a bus and messaging engine if you are using a managed quality of service. If your chosen quality of service is Unmanaged Non-Persistent, any binding that you specify is ignored. The quality of service is defined on the WS-ReliableMessaging settings form for your chosen policy set. For more information, see Configuring the WS-ReliableMessaging policy.
- When many applications use the same messaging engine, it can impact performance. Factors to consider include the number of applications that are already binding to the messaging engine, the CPU utilization, and the message throughput. To improve performance for a single server configuration, create a new messaging engine to bind to your application.
