This tutorial walks you through the sample common data object code, then describes how to use different data objects for input, output, and common data. How to develop a client application and service to share data among all tasks in a session. The data is shared by all invocations of tasks within the same session.
Common data is data that can be made available to service instances for the duration of a session.
Use common data when you need to set up the initial state of a service, and you only want to do it once, not on every task. Common data is useful for passing data from a client to a service. The service loads the data when the session is created.
You can use common data, for example, to set the environment in the service that is common to all tasks in a session. This way you only need to set the environment once, when the session is created.
Symphony attempts to use the same service instance for all tasks in a session. A service instance is made available to other sessions only when session workload completes, a session is closed or aborted, or when another session of higher priority is assigned the service instance.
When you add an application through the DE PMC, you must use the Add Application wizard. This wizard defines a consumer location to associate with your application, deploys your service package, and registers your application. After completing the steps with the wizard, your application should be ready to use.
