955 Running the SOLe
On
line Test
The SDLC on line test verifies correct operation
of
the communications link between two systems,
or
between
the system and attached
SDLC devices (for example, IBM
5251
Model
12
or IBM 5294 controllers). To run
the
SDLC on line test to another system, a similar support program must be started
at
the remote location.
To run the
SDLC on line test to a remote work station, you must
use
the VARY command.
See
"329
Summary
of
Useful SSP Procedures" on page
3-11
to change the selected line to off-line.
1.
Key in SDLCTEST
on
the SSP command line and press the Enter key.
2.
Insert diskette
61,
when prompted for a diskette.
3.
Select:
a.
A line number to
be
tested.
b.
REQUESTOR (to start the SDLC test to another system or device) or RESPONDER (to answer the
SDLC test request from another system).
c.
YES to review or change the communications configuration. Always attempt to run the test with the
present configuration before making any changes unless you are attempting to run to a system or
device that the customer was not using. ALTERCOM changes the configuration only for the display
station
at
which it
is
run.
If
configuration
is
correct and diagnostics run
at
the system console, but
the customer
job
fails when it
is
run from another display station, repeat step 3
at
that display
station.
d. The hexadecimal address
of
the remote system, controller, or device to be tested.
Note:
If
the network
is
a point-to-point network, you can
use
hex
FF
as the address.
If
the network
is
a multipoint network, you must obtain the correct address from the customer.
4.
Select the test to be run.
5.
Select the number
of
times the test should be run. You should run two or more
of
the first
six
tests
at
least
10
times each.
6.
Analyze the results.
If
the test ends with no errors, the communications link
is
operating correctly now.
