A deployment specification specifies a set of properties that determine execution parameters of a component artifact that is deployed on a node. A deployment specification can be aimed at a specific type of container. An artifact that reifies or implements deployment specification properties is a deployment descriptor.

*Description

In the metamodel, a DeploymentSpecification is a subtype of Artifact. It defines a set of deployment properties that are specific to a certain Container type. An instance of a DeploymentSpecification with specific values for these properties may be contained in a complex Artifact.

*Attributes

ComponentDeployments Package

Issue 9191 - add multiplicities

• deploymentLocation : String [0..1] The location where an Artifact is deployed onto a Node. This is typically a 'directory' or 'memory address.'

• executionLocation : String [0..1] The location where a component Artifact executes. This may be a local or remote location.

*Associations

ComponentDeployments Package

• deployment : Deployment [0..1] The deployment with which the DeploymentSpecification is associated.

*Constraints

[1] The DeploymentTarget of a DeploymentSpecification is a kind of ExecutionEnvironment .

Issue 8139 - add OCL for both constraints

self.deployment->forAll (d | d.location..oclIsKindOf(ExecutionEnvironment ))

[2] The deployedElements of a DeploymentTarget that are involved in a Deployment that has an associated DeploymentSpecification is a kind of Component (i.e., the configured components).

self.deployment->forAll (d | d.location.deployedElements->forAll (de | de.oclIsKindOf(Component)))

*Semantics

A Deployment specification is a general mechanism to parameterize a Deployment relationship, as is common in various hardware and software technologies. The deployment specification element is expected to be extended in specific component profiles. Non-normative examples of the standard stereotypes that a profile might add to deployment specification are, for example, «concurrencyMode» with tagged values {thread, process, none}, or «transactionMode» with tagged values {transaction, nestedTransaction, none}.

*Notation

Issue 7362 - Clarifying example in Figure 10.11.

A DeploymentSpecification is graphically displayed as a classifier rectangle (Figure 10.11) attached to a component artifact deployed on a container using a regular dependency arrow.
