Diagnostic software programs monitor system operations, detect faults, and
clear faults. Some programs run continuously, while some are scheduled.
Diagnostic programs are resident or non-resident software programs.
Resident programs, such as the Error Monitor and Resident Trunk
Diagnostic, are always present in system memory. Non-resident programs,
such as the Input/Output Diagnostic and Core Equipment Diagnostic, are
used as Midnight and Background Routines or for interactive diagnostics.
Non-resident programs are loaded from the system disk and are run as
scheduled or upon request.
See the Software Input/Output: Maintenance (553-3001-511) and Software
Input/Output: System Messages (553-3001-411) for detailed information on
all diagnostic programs.
Non-resident programs are also called overlays or loads. They are identified
by a title and a number preceded by the mnemonic for load (for example,
Trunk Diagnostic — LD 36).
MG 1000T
The MG 1000T platform supports the same overlay commands and
associated TN format (c u) as the CS 1000S system.
CS 1000E
The CS 1000E Core Call Server and MG 1000Es support the overlay
commands and TN format (l s c u) associated with Large Systems.
The Call Server also supports additional maintenance functions in Overlays
30, 31, 32, 34, 36, 38, 45, 46, 77, and 80 in the same manner as CS 1000S
systems, while maintaining the l s c u TN format.
