APPC Subsystem Configuration
Configuring the APPC Subsystem
Fields TP Name Required. The name of a new remotely initiated TP
you want to configure or an existing remotely initiated
TP whose configuration you want to modify. A TP name
can be up to 8 alphanumeric characters; the first
character must be alphabetic. Up to 256 TP names may
be configured.
The remote TP sends a TP name to indicate the local
TP with which it wants a conversation. When the APPC
subsystem receives the local TP name from the remote
TP, it streams a job that runs the local TP. The job
name for each remotely initiated local TP is configured
in the “APPC: Transaction Program Data” screen.
The TP Name field must match the TP name sent by the
remote TP. It must also match the
LocalTPName
parameter of the local TP’s TPStarted intrinsic call,
and it must match the
LocalTPName parameter of the
local TP’s MCGetAllocate intrinsic call.
NOTE On older versions of the APPC subsystem, the remote TP sends the job
name in its allocate request. To avoid changing remote Taps that work
with older versions of the APPC subsystem, make the TP Name field of
the “APPC: Select Transaction Program” screen (and the
LocalTPName
parameter in the local TP) match the name of the job file and the job
name in the JOB card statement of the file.
New Name The new name you want to assign to a configured TP.
To rename a TP, enter its old name in the TP Name
field, enter its new name in the New Name field, and
press
[f4] (Rename).
Figure 4-14 shows how remotely initiated TPs are started. All of the
following values must match:
• The TP Name configured in the “APPC: Select Transaction Program”
screen.
• The local TP name sent by the remote TP in the allocate request.
• The
LocalTPName parameter of the TPStarted intrinsic.
• The
LocalTPName parameter of the MCGetAllocate intrinsic.
