Configuring APPC Communication
Defining Modes and Classes of Service
The initial setting for the number of request units
(RUs) that the local LU can receive before it must send
a pacing response to the remote LU. This can be safely
set to
4
.
Setting it higher can improve performance in some
circumstances, but doing so also increases memory
usage.
Maximum window size
The maximum number of request units (RUs) that the
local LU can receive before it must send a pacing
response to the remote LU.
This value is optional. If it is not supplied, the
maximum receive pacing window is unlimited. If a
value is supplied, it is used to limit the size of the
receive pacing window for adaptive pacing adaptive
pacing . If adaptive pacing is not used, this value is
ignored.
The pacing window can be from
0
through
32767
bytes.
A value of
0
specifies an unlimited window.
If the adjacent node supports only fixed pacing, these
values determine the fixed-pacing window size; but the
adjacent node can still set a window size through
negotiation. If the adjacent node uses adaptive pacing,
these values set the initial window size.
Session timeout
The number of seconds (
0
-
65535
) that an LU 6.2
session using this mode must be inactive before it can
time out. Changing this value affects only sessions that
are activated using this definition (not sessions that
are already active).
If you use a value of
0
, sessions are timed out as soon
as they become free.
Maximum RU size
A range that determines how much data is buffered
before being sent to the partner LU.
The upper limit can be from
256
through
62440
bytes.
You can safely set the upper limit to
1024
bytes.
Setting it higher can improve performance in some
circumstances, but doing so also increases memory
usage.
