Conﬁguring APPC Communication

Deﬁning TPs

For an invokable TP, you can also specify a timeout

value, to limit the wait for an allocation request. (You

can only conﬁgure this option using command-line

administration.)

SNAplus2 uses the invokable TP deﬁnition for the

following purposes:

• When a TP issues Receive_Allocate, SNAplus2

searches for an invokable TP deﬁnition with the

appropriate TP name. If the deﬁnition exists, and

includes a value for the Receive_Allocate timeout,

SNAplus2 uses this value when processing the

Receive_Allocate; otherwise it uses the default (no

timeout, which causes the TP to wait indeﬁnitely).

• When an incoming Allocate request arrives at the

target system, and the requested TP is not already

running with a Receive_Allocate outstanding,

SNAplus2 searches for a TP deﬁnition with the TP

name speciﬁed on the incoming Allocate. If the

deﬁnition exists, SNAplus2 uses the information in

this deﬁnition to start the TP (if multiple instances

are permitted or the TP is not already running), or

to determine that it should queue the incoming

Allocate (if the TP is already running and multiple

instances are not permitted ).

If necessary, you can conﬁgure both types of deﬁnitions for the same TP

(for example, to deﬁne conversation security for an invokable TP).

To conﬁgure a TP deﬁnition, use one of the following methods:

To deﬁne APPC characteristics:

Use either of the following methods:

Motif administration program

Select APPC and Transaction Programs from the

Services menu on the Node window. When SNAplus2

displays the TP window, select the bottom pane and

click on the Add button, or select an existing TP

deﬁnition and click on the Zoom button.

Command-line administration program

Issue the snapadmin define_tp command.

To deﬁne an invocable TP:
