Mapping resources and components to environments

Edit online
You can specify where components are deployed by adding a resource or resource group to the environment. Then, map the components to those resources.

About this task

Resources and resource groups identify the agents that do the work of deploying components and provide other configuration information. You must identify the resources for the environment and then specify which components run on which resources.

If you are using IBM® WebSphere® Application Server, you can import information from cells as resources; see Importing resources from WebSphere Application Server.

Procedure

  1. To open the environment, click Applications > application > environment.
  2. Click Add Base Resources to display the Add Resource to Environment window for the selected environment.
    All previously defined resources are available for use, as shown in the following figure:
    Selecting resources for an environment
  3. Select the check box that is associated with the resource or resource group to use.
    You can select more than one resource. Selecting a resource that was previously added to the environment has no effect. Adding more than 10 base resources in an environment may result in performance issues.
  4. Click OK. The selected resource or resource group is added to the environment.
  5. To remove a base resource from the environment, in the same row as the resource, click Actions > Remove From Environment.
    Removing a base resource removes its child resources as well. Starting from v7.0.5.1, you can delete a resource from the environment. Note that deleting a resource from the environment resource tree deletes the resource from the system. Delete a resource from the system as follows:
    1. Go to Settings > System Settings.
    2. Enable Deleting Resources from Environment Resource Tree, confirm, and save your changes.
    3. Go back to your environment resource tree, in the same row as the resource, click Actions > Delete.
  6. Map each component in the application to the resources.
    Each component must be mapped to at least one resource. You can map the same component to multiple resources. Or to specify that the component is deployed more than once to the environment, you can map the component multiple times to the same resource. There are several ways to map components to resources:
    • To add components one at a time, in the same row as the resource, click Actions > Add Component, and then select the component.
    • To drag components, click Show > Components. Then, in the list of components that are associated with the application, drag one or more components to the resource.
    • To add multiple components at once, ensure that each component has the same tag. Then, in the same row as the resource, click Actions > Add Component Tag, and specify the tag that identifies the components.

Results

The environment is populated with resources and components.

What to do next

Note: For z/OS deployments, you must use a one-to-one (1:1) mapping between environments and resources. This practice ensures that each resource is assigned exclusively to a single environment within the application context.
After mapping components and resources, create an application process. For information about creating application processes, see Creating application processes.
