Configuring APPC Communication

Defining TPs

Defining TPs

This section explains how to define an APPC TP.

In most cases, you do not need to define TPs that run on the SNAplus2 system; but you do need to configure a TP definition in the following cases:

APPC Characteristics

If the TP on the SNAplus2 computer is the invoking TP (or source TP—the TP that starts the APPC conversation) and you do not need to restrict access to the TP, you do not need to define the TP. You can, however, define an APPC TP, as described in “TP Definition Parameters”, to specify the following characteristics:

To define conversation security for the TP.

To indicate whether the TP uses basic or mapped conversations.

To specify sync point processing.

To specify handling of PIP data.

Invokable TPs

To enable a TP to be started automatically in response to an incoming allocation request, define it as an invokable TP as described in “TP Invocation Parameters”.

An invokable TP (or target TP) is one that is started in response to an incoming allocation request. You must create a TP definition for an invokable TP. An invokable TP can be an APPC TP that issues RECEIVE_ALLOCATE, or a CPI-C application that issues Accept_Conversation or Accept_Incoming.

In this section, the phrase “Receive_Allocate” is used to indicate any of these three API calls.

You can also define an invokable TP to route incoming allocation requests to a running TP.
