NOTE
Refer to Appendix A of this manual, for SADIE tape
release 3.2 test descriptions.
SADIE is a stand-alone diagnostic executive
and
diagnostic
library.
It provides thorough testing of all mainframe com-
ponents.
SADIE is based on the construction,
modification,
storage,
and
execution
of
test
lists.
The commands to
operate on these test lists are displayed in a menu-oriented
format
on the CRT to minimize the documentation support re-
quired and to allow
a
first-time
user
to
execute
SADIE
without
constant
reference
to an instruction manual.
The
SADIE program code and associated data sets
reside
on
the
SADIE
diagnostic
tape
cartridge, which is inserted in the
tape slot and run whenever degraded system operational capa-
bility
is
suspected.
The object code for SADIE resides in
the lower part of a memory segment; the diagnostic test
re-
sides in the upper part of the segment.
5.11.1.
Purpose of SADIE:
The basic purpose of. SADIE is to
test
the· system
hardware.
To do this, SADIE allows con-
struction and execution of test lists." A test list consists
of
lines
executed
sequentially.
A line contains either a
test or a control statement, up to four parameters necessary
for
execution
of
the test or contrQl statement, and a re-
petiti6n count for all noninteractive tests.
Normal sequen-
tial
execution of a test list can be altered by a GOTO con-
trol statement or interrupted by a PAUSE
control
statement
in
the list.
There are control statements to specify line-
printer test output as well as the
visual
display
output.
Other
control
statements
specify that that the tests that
follow should pause on a hard-error condition.
Every
test
list
includes a termination line consisting of an EOL (end-
of-list) in the test-name
field
of
the
display.
Single
tests can also be executed. SADIE considers a single test to
be a two-line test, where the second line is the EOL.
As a test list executes, errors are logged into a cumulative
error
log and an error summary log for the test.
The cumu-
lative log contains the last 20 error messages.
The
error
summary contains the number of laps completed, the number of
hard and soft errors, and the completion status of each line
in the list.
Both logs remain available until the next test
list is run or until the end of the SADIE session.
