WebSphere Application Server V7.0: Concepts ... - IBM Redbooks

► Server scope
The server scope value limits the visibility to the named server. This is the
most specific scope for defining resources. The resource factories that are
defined within the server scope are available for applications that are
deployed on this server and override any resource factories that have the
same JNDI name defined within the node and cell scopes. The resource
factories that are defined within the node and cell scopes are available for this
server to use, in addition to the resource factories that are defined within this
server scope.
► Application scope
The application scope value limits the visibility to the named application.
Application scope resources cannot be configured from the Integrated
Solutions Console. Use Rational Application Developer Assembly and Deploy
V7.5, or the wsadmin tool to view or modify the application scope resource
configuration. The resource factories that are defined within the application
scope are available for this application to use only. The application scope
overrides all other scopes.
You can define resources at multiple scopes but the definition at the most specific
scope is used.
When selecting a scope, the following rules apply:
► The application scope has precedence over all the scopes.
► The server scope has precedence over the node, cell, and cluster scopes.
► The cluster scope has precedence over the node and cell scopes.
► The node scope has precedence over the cell scope.
When viewing resources, you can select the scope to narrow the list to just the
resources defined at the scope. Alternatively, you can select to view resources
for all scopes. Resources are always created at the currently selected scope.
Resources created at a given scope might be visible to lower scope. For
example, a data source created at a node level might be visible to servers within
the node.
