supervisory services and monitoring of message exchanges
are provided by TBT/400 :
basic operating essentials of a communications platform can
be resumed as follows:
the activity in progress
aware of the activity to follow
the transfers effected
into the errors and incidents
them and remedy them
supervisory aspects of TBT/400 are based on the above requirements.
its supervisory layer, TBT/400 allows
one to monitor at any given time the state of the communications
in progress, to follow or already effected.
is a permanent display of all the communication
elements specified in TBT/400.
various functionalities provide condensed views of the different
logical queues, but also exhaustive details of all
elements transmitted or to be transmitted, as well
as the data-file.
envelopes, acknowledgments of receipt, distribution advices,
are fully archived and reconciled with the messages
transmitted. These various elements are all available for
consultation via the supervisory menus.
addition, so as to optimize the job of the operator, multi-criteria
searches on important zones describing the transfers,
are possible for current or historical messages.
TBT/400 gives immediate
access to the list of erroneous transfers. These
are signaled in red (or double intensity for monochrome
screens) via the supervisory menus.
an application processing an incoming file, to assign a return
code to it. This authorizes, with a little work by the application, the
supervision of the processing of the incoming files.
function key gives access to spools of the job having processed
an incoming file. It is therefore almost instantaneous to recover
the 'JOBLOG' of a job which processed the files.
message can be retransmitted from the screen:
this allows, for example, the correction of the erroneous
application name for an incoming message, for internal
recycling and the automatic processing by the application.
essential network exchanges (e.g. identification) are archived including
the translation of known diagnostic codes to accelerate
is even possible to display, even amend, if one is
authorized, a file of TBT/400 transmitted or received (just
as far as a hexadecimal view if necessary), simply by using
a function key .
of printing the files received.
errors linked to the network (for example the X25 or BSC
line out of order) are signaled in the Operator
Message Queue. Functional errors (for example refusal
of a sign-on) are placed in a dedicated Message Queue accessible
directly from the TBT/400 menus.
option to trace exchanges can be activated allowing, in complex
cases, or for the final application testing, to have the
necessary elements to resolve problems.
All OS/400 commands useful
for monitoring the functioning of TBT/400 are taken
out of the hands of the users, so as to provide an easy aid,
the user not having to understand anything of the native OS/400 commands.
