To use WS-ReliableMessaging, you attach a standard WS-Policy, which includes reliable messaging assertions, to a web service descriptor. For more information about defining your own policies, see Web Services Developer’s Guide. For instructions about attaching a WS-Policy to a web service descriptor, see webMethods Service Development Help.

To use WS-ReliableMessaging, you can attach a pre-defined WS-Policy named ReliableMessaging that Integration Server provides. This policy is available in the following directory:

Integration Server uses a unique reliable messaging sequence key to track the progress of a set of messages that are exchanged reliably between a web service provider and consumer.

Integration Server supports only the In Order delivery assurance for reliable messaging.

You use the Integration Server Administrator to configure reliable messaging for web services. By default, Integration Server applies the reliable messaging configuration defined on the Settings > Web Services > Reliable Messaging > Edit Configuration page to all web service providers and consumers. If you want to override the server-level reliable messaging configuration for a specific web service provider or consumer, define reliable messaging properties for the associated web service endpoint alias.

Integration Server provides pub.soap.wsrm built-in services to create and manage reliable messaging sequences. For more information about these built-in services, see webMethods Integration Server Built-In Services Reference SOAP Folder.
