Web Services Distributed Management in a WAS ND cell
We can use Web Services Distributed Management (WSDM) to manage appserver instances within a WAS ND cell. The administrative support and visibility for WSDM in a cell is obtained through interaction with each WSDM application deployed on the application server.
WSDM is a system application and it is disabled by default when the product is installed. We must first enable WSDM before you can use it to manage the product resources. Use scripting to enable WSDM.
In the multinode WAS ND environment, the management code runs across a distributed network of Java virtual machines with a central access point as the dmgr process for the entire network or cell. Several different application server Java virtual machines might be managed within a cell. We can manage an application server Java virtual machines within a cell through the WSDM application installed on dmgr. The WSDM application acts as an administrative client to the managed application server. Figure 1 illustrates this environment with an Autonomic Computing Manager interacting with the single application server implementation of WSDM to expose the manageability of that application server. We can build a federated dmgr cell from individual appserver instances by running the addNode utility program to add the appserver instances to the centrally managed cell. After a node is added to the cell, the manager can still manage each application server within the cell through the installed WSDM application on the dmgr.
