The process of developing a WebSphere MQ cooperative application is similar to building other types of CA Gen cooperative applications. The CA Gen Design tool provides a set of integrated facilities that allow an application developer to specify different aspects of the CA Gen cooperative application. These tools include the following facilities:
In addition to the tools used to design an application, CA Gen provides a set of integrated tools to describe the construction characteristics of the various components that make up the modeled application. These integrated tools allow you to perform the following tasks:
Within a model, each defined component has a set of properties that can be added to the model definition of the application. For a cooperative application, there is a set of properties that apply to a window manager, and a set of properties that apply to a server manager. Each individual property typically has a default value, although the construction tools allow overriding of the various property value settings.
In addition, the target execution environment of the application component can be detailed and added to the model definition of the application. Environment parameters are used when generating a given application component, and each application component can have its own set of environment parameters, or it can make use of a set of default environment parameters defined for the entire application.
When an application component is generated, the values of the environment parameters determine which of the property values of the component are relevant. For example, WebSphere MQ properties are only referenced when generating a WebSphere MQ application component, and TCP/IP properties are only referenced when generating a TCP/IP application component.
The transport mechanism used by a DPC (window manager, or proxy) to flow to a DPS (server manager) is a characteristic of the execution environment of the server manager. The associated environment parameters of the server manager define its communication method and the TP Monitor environment into which it is deployed. That is, the specific transport mechanism generated for a window manager or proxy to use for a given DPC-to-DPS flow, is determined by the environment parameters associated with the server manager containing the target DPS.
Within construction, the component of an application can have its properties and environment parameters detailed using either the packaging or the generation tool.
