TN3270 Init Status Delay Timer
ID: Q138016
|
The information in this article applies to:
-
Microsoft SNA Server, versions 2.11, 3.0, 4.0
SUMMARY
The TN3270 Service can be configured to support the "Init Status Delay"
timer. This timer inhibits the TN3270 Server from sending status messages
to the TN3270 client during session establishment. To enable the "Init
Status Delay" timer, do the following:
SNA Server 2.11
- Go to TN3270 Admin, Select the Options button.
- Input the desired value.
- Select OK
- You must restart the TN3270 service for the changes to take effect.
SNA Server 3.0
- Under TN3270 Servers folder, select the TN3270 Server you wish to change.
- Go to the View | Properties to display the <TN3270 Server> Properties
dialog box.
- Select the Settings tab and input the desired value.
- Select OK
- You must restart the TN3270 service for the changes to take effect.
When a client connects to the TN3270 Server, the TN3270 Server sends the
TN3270 client messages to display on the client terminal, such as "Client
request pending" or "host LU found". To avoid a flurry of these messages if
the connection comes up quickly, the TN3270 Server does not send any of the
messages while the Init Status Delay timer is running.
MORE INFORMATION
The following example shows the client receiving multiple status messages
while an SDLC link service is activating. The timer is set for 2 seconds as
noted in these outputs:
TEV_SNAInitTimerStarted
Delay=2000 seconds
NOTE: The trace file shows this value incorrectly by a factor of x1000
seconds.

The last example shows the timer set to 200 seconds, and the timer being
canceled. The client does not receive any status messages because the link
activates before the timer expires.
NOTE: The timer is set for 200 seconds TEV_SNAInitTimerStarted:
Delay=200000 seconds. The trace file shows this value incorrectly by a
factor of x1000 seconds.
