User-written Clients That Use a Generated Proxy

A user-written client application can use a generated proxy to facilitate a flow to a target DPS. Each proxy is generated for a specific DPS. CA Gen provides support for the following types of generated proxies:

Each proxy exposes an interface, an API, which a user-written application uses to invoke the associated DPS. Each type of proxy has its own runtime.

Each proxy runtime offers one or more user exit functions that support customizing the proxy runtime. For more information about the user exit functions available for each of the proxy runtimes, see the User Exit Reference Guide.

Each proxy runtime provides an interface to one or more communication runtimes. For more information about the CA Gen provided communications support available for use each type of generated proxy, see Communications and Middleware.

For more information about how proxy clients select a communications runtime, see Overriding Communications Support at Execution Time.
