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:
