WSE • 3/21/97 16720 — 5 SE 6000 Security Management System
(iii) This system shall replace a failed Host CPU, shall have all necessary system
applications loaded, and shall be activated by connection to the proprietary security
key device utilized with Host system.
(iv) The Redundant Stand-By System shall only be activated only in the event of
hardware failure at the Primary System.
2) Host/LC:
(i) The second level of redundancy is available through the standard architectural
design of the SE 6000.
(ii) In the event of a failure of the LC computer, Host / LC design shall be implemented
through the configuration of Host to accommodate manual switchover to the LC
computer.
(iii) At the time of switchover the pollers shall be activated through Host rather than
through the LC. Host would then function as the LC for monitoring purposes until
the LC was again functional.
(iv) If a Host failure is experienced, the LC would continue to perform in its usual
manner.
3) Fault Resistent System (FRS):
(i) This level of redundancy shall support simultaneous reads and writes to two disks
of two duplicate platforms configured identically.
(ii) Under normal conditions the Primary Host would be the main functioning system
writing all transactions to the disk of the Secondary system in real-time.
(iii) In the event of Primary Host failure, the FRS CPU will automatically seize control of
the entire system until the Primary Host is restored and control returned to the
Primary Host.
C. Sortware Platform
1. Operating System: SCO UNIX.
2. Database Management System:
a. System shall utilize a high-performance relational database management system such as
UNIFY Accell/SQL.
b. The system shall be capable of multi-user and multi-database support in a UNIX
environment.
3. Advanced Visual Report Writer:
a. The system shall utilize a powerful visual information and retrieval tool to extend the
reporting power of UNIFY Accell SQL application development system.
b. The retrieval tool shall work seamlessly with Accell SQL to provide rapid generation of
custom reports and business graphics.
4. Screen Interface System (on Ethernet only):
a. X-windows capabilities shall be provided to support File Maintenance, Reporting, Monitor
and Graphics Windows.
b. These functions shall be available on the PC Terminals connected to the system, and shall
incorporate X-Windows software.
5. Networking:
a. Networking capability shall be necessary to implement large scale and/or multi-location
systems with security devices and/or computers distributed to remote locations while overall
control of the network is maintained at a central location. Local Area Networks (LANs) or
Wide Area Networks (WANs) connected via dedicated or dial up communications lines may
be required.
6. “C” Programming Language:
a. The application shall be written in the “C” programming language.
b. This standardization shall provide for greater ability to support and enhance the system in
the future.
