Diagnostic software programs monitor system operations, detect faults, and
clear faults. Some programs run continuously; some are scheduled.
Diagnostic programs are resident or non-resident. 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 Common 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.
Non-resident programs are called overlay programs or loads. They are
identified by a title and a number preceded by the mnemonic for load (for
example, Trunk Diagnostic—LD 36).
See X11 Administration (553-3001-311) for detailed information on all
diagnostic programs.
The Error Monitor is a resident program that continuously tracks call
processing. The Error Monitor generates system messages if it detects invalid
or incorrectly formatted call-processing information.
System messages generated by the Error Monitor are preceded by the
mnemonic ERR, which usually indicates hardware faults, or the mnemonic
BUG, which usually indicates software problems. With prompt ERRM in the
Configuration Record (LD 17), you can instruct the system to print or not
print ERR or BUG messages.
Refer to X11 System Messages (553-3001-411) for help in interpreting system
messages, including ERR and BUG.
The Initialize Program momentarily interrupts call processing as it clears
common equipment faults. It then rebuilds call-dependent data and generates
system messages, with the mnemonic INI, that indicate the status of the
system. This process is called an initialization.
