Node rules identify the endpoints of the application pattern. There are two types of node rules:

“Mandatory Node Rules” on page 56

“Unifying Node Rules” on page 57
Connectivity rules identify the connections between the nodes. Connectivity rules also assign each node as a
source or target of the application pattern definition.
Node Rules
In Figure 6 ‐ 2 , there are three endpoints of the application pattern:

Oracle database

Jboss Server

Apache Server.
Figure 6-2. Application Pattern Endpoints
This application pattern definition requires three node rules to identify each endpoint.
Connectivity Rules
Connectivity rules identify the connections between the endpoints and are used to assign an endpoint as a
source or target of the application pattern.
Figure 6 ‐ 3 demonstrates a connectivity rule that includes JDBC and HTTP connections, as well as assigns the
Apache Server as a source to the Jboss Server (target) and the Jboss Server as a source to the Oracle database
(target).
Figure 6-3. Connections Between Endpoints
Mandatory Node Rules
Application pattern definitions also require that you define a node rule either as:

Mandatory

Optional
Mandatory elements must exist in the environment to be identified as an instance. They are core elements of
the application pattern definition.
Optional elements are not core and, if they exist, they are included in the discovered instance.
N
OTE
ADM requires that you define at least two node rules, one for the source and one for the target, plus
one connectivity rule for each application pattern definition.
