Overriding Communications Support at Execution Time › Execution Time Configuration

Execution Time Configuration

For designating which communications type a client use to process a cooperative flow occurs when the client application initiates a flow to a target server. The ability to override the communication type at execution time eliminates the need to re-generate the client application to switch the type of transport to be used to process a given cooperative flow request.

In addition to the communication type, CA Gen lets the attributes that are associated with a selected communications type be set (or overridden) at execution time. The following bullets show two opportunities to influence the values of the communication attributes:

• An external configuration file that is known as the Comm Config file
• User exits invoked from each of the various Communication Runtimes

Proxies offer an API to override their Generation Time Configuration. A developer of a user-written application that use a generated CA Gen proxy can override the communications properties of the proxy by using the generated comCfg interface for that proxy.

Note: For more information about how to override a proxy communication configuration, see the Distributed Processing—Proxy User Guide.
