Migrate a v6.1 WS-Notification configuration from WAS v6.1 to v7.0 or later
We can migrate an existing v6.1 WS-Notification configuration to run in a WAS v7.0 or later environment. This topic assumes that we have the following configuration:
- An existing server or cluster installation of WAS v6.1 that is ready for migration, including at least one WS-Notification service, service point, and underlying service integration bus.
- Existing subscriptions with associated messages pending notification.
- Existing operational WS-Notification client and web service applications that are known to transmit and receive notifications through the existing Version 6.1 WS-Notification service.
When you migrate the system from WAS v6.1 to v7.0 or later, any existing WS-Notification configuration (for example WS-Notification services, service points, administered subscribers), and the associated service integration bus resources (for example inbound services and endpoint listeners) are automatically migrated to valid configuration elements within the new installation. The services and service points are migrated to v6.1 WS-Notification services and service points, the endpoint URLs for the service points are unchanged, and the functions supported are exactly the same as in WAS v6.1. For example, reliable notification is not possible with v6.1 WS-Notification services and service points.
Any messages pending notification are delivered following the update and server startup sequence.
For network deployment scenarios where a dmgr is upgraded to WAS v7.0 or later before its federated servers, the federated servers are not available as bus members for v7.0 WS-Notification service points.
Procedure
- Migrate your product configuration from WAS v6.1 to v7.0 or later.
- Check that notifications are being published and consumed correctly in your migrated system.
Initiate the program, process, or application that includes the WS-Notification client (or clients), and that causes notifications to be requested and transmitted.
Results
The WS-Notification services and resources are migrated to Version 6.1 WS-Notification services and resources that run under WAS v7.0 or later. Any messages pending notification are delivered.
What to do next
You are now ready (optionally) to prepare your migrated Version 6.1 WS-Notification configuration for reliable notification.
