TOMAS - CONTINUOS
TOMAS is fully automated system and
requires no specialized crew, i.e. operates without any human interventions,
even in the case of unstable power supply. Computer and workstations could
be on for years, as well as TOMAS.
Usually, computer systems require
system and application programmers and operators for activating and deactivating
database, purging disks, running programs for report generation etc. TOMAS
performs this automatically and can operate for years, without any human
This is done in the following way:
Computer and TOMAS are on 24 hours/day,
Users perform only database updating or
making reports that are not in the informationbase.
Computer is connected to programmable
UPS device (Uninterrupted Power Supply) so that:
in case of power supply cut, computer
could work for further 15 min
...so that UPS could start:
the procedure for deactivating database
and the computer, 5 minutes after power supply is interrupted...
...and the procedure for activating computer
and database, when power supply is restored.
Normal daily deactivating and activating
of the database is automatically performed in pre-programmed time, e.g.
during night and takes 2 - 3 minutes. This is to be done:
To copy the database from central memory
to disks, for security reasons. Copy could be additionally done to external,
removable disks, to be held in safe place, for more security.
To purge scratch files that are generated
by daily use of TOMAS.
The resulting effects for the users are:
Informationbase is automatically updated
once or several times per day, at pre-programmed time. This could be done
at any time, i.e. while users are active.
permanent full availability of the information
increased reliability - no chance for
long life of the equipment, i.e. protection
of investment in information system
decreased total information costs, for
specialized crew is not needed and long life of the equipment.
