Web Services Distributed Management support in the appserver
Deprecated Feature: Web Services Distributed Management (WSDM) is a deprecated feature in WAS ND v7.0
The Web Services Distributed Management (WSDM) support for a Web service in WAS runs within an appserver that has exposed management functions.
The WSDM application is packaged as a Java EE EAR file and deployed as a system application.
WSDM is disabled by default. You must enable WSDM.
WSDM support for WAS consists of two parts:
- runtime environment
- resource model and service implementation
Web Services Distributed Management runtime environment and support
The WSDM runtime environment interacts with the underlying Web services platform to service requests and responses, leveraging...
- WS-Addressing
- WS-ResourceFramework
- WS-Notification
For each request, the WSDM runtime environment routes the request to the appropriate resource service implementation based on the endpoint reference, (EPR), defined by the WS-Addressing specification.
Each EPR contains...
- target address
- runtime specific data
- reference properties
After the resource service implementation returns a response, the WSDM runtime environment wraps the response into an appropriate SOAP message format specified in the Management Using Web Services (MUWS) spec and returns the response back to the requester. The appserver leverages Apache Muse 2.0 to provide runtime and development support for WSDM.
WSDM resource model and service implementation
The resource model defines interfaces and includes capabilities defined in the two WSDM specifications...
- Management Using Web Services (MUWS)
- Management of Web Services (MOWS)
The implementation does not introduce new functions into WAS ND, but rather, an alternative interface for accessing existing administration and programming functions. Each resource is associated with a WSDL file that contains the definition of its manageability capabilities.
Security
The implementation is attached to the WSSecurity default policy set and runs the admin operations from the client user identity. This user identity must have privileges to perform any admin action. It is the role of the autonomic computing (AC) manager that makes requests for the WSDM implementation to verify the user of that manager has appropriate authorization to perform administration and any other functions exposed by the AC manager.
The benefit of WSDM support in the appserver is that WAS ND can participate in multiple product management solutions in a standard way.
