Communications applications that are used in an APPC (advanced program-to-program) environment are also available to be used in an APPN and HPR environment; only the method by which data is transported is changed. APPC delivers the data from applications higher in the SNA layers down to APPN for transportation through the network. For more information on communications applications, see the following:

• User-written APPC applications

• Distributed data management (DDM)

• Application programming interface (API) performance considerations

When you encounter problems that indicate that the route to the remote location cannot be found, you can attempt to make the connection again with the Start Pass-Through (STRPASTHR) command. See the Solve remote communication problems using STRPASTHR topic for more information.
