Operational Decision Manager virtual application patterns provide artifacts that define a running Operational Decision Manager environment after the pattern is deployed.
IBM Operational Decision Manager Application Pattern is made of components that provide the functions and interaction between functions to create an operational IBM ODM application environment when a pattern is deployed in the cloud. To provide a working Operational Decision Manager environment in the cloud, you define the properties of the related components. When the patterns that contain these components are deployed, the components become virtual machines in the virtual application instance. All IBM ODM Application Pattern components are under the IBM ODM Components section on the left panel of the Virtual Application Builder window when you are editing a virtual application pattern.
To create a working Operational Decision Manager environment, you define the relationship between the components through links when you are editing a pattern in the Virtual Application Builder window.
You can further define the components of a pattern by adding policies. Policies can be applied globally at the application level or specified for individual components. For example, a scaling policy defines criteria for dynamically adding resources from the virtual application.
Two virtual applications might include identical components but require different policies to achieve different service-level agreements. For example, you can add a decision management scaling policy to the application component and specify requirements, such as a processor usage threshold to trigger scaling the application. At deployment time, the topology of the virtual application is configured to dynamically scale the application.
Policies can be applied only to particular types of components.
