WebSphere ESB 602: Administrative dynamicity

In WebSphere ESB 6.0.1, the amount of post-deployment administration you could carry out was limited to the ability to view module import and export details, and the capability to modify the target of an import with an SCA binding. Within WebSphere ESB 6.0.2 we have greatly improved the influence the administrator can have on a deployed mediation flow in two ways.

The first of these is to extend the ability to re-target endpoints to include Web Services endpoints. Thus, an administrator can override the endpoint URL for SOAP/HTTP and SOAP/JMS endpoints. This administrative capability is in addition to the new dynamic endpoint selection functionality I’ve already talked about and is more static in nature. You might ask which one takes precedence and the answer is any endpoint dynamically selected by the mediation flow.

More significantly, we’ve introduced the concept of module properties. An Integration Developer can now opt to promote certain properties of primitives within the mediation flow up to the module, where they will be exposed for viewing and modification by the administrator post-deployment. This leads to a number of interesting possibilities, from being able to make small changes to the behaviour of the flow such as whether or not a Message Logger logs within a global or local transaction, to more creative uses which can have an effect on the outcome of the flow. The combination of administrative properties, the Message Element Setter and a Message Filter primitive is a prime example of a possible application of the latter.
