collected from N number of instruments had to be
stored and made available to engineers across the company. The
challenge was to provide a cost effective solution
as well as a robust system that can handle the traffic as well as
Durability Solution: We realized
from the beginning that the system has to take advantage of a web
browser software since it is readily available at everyone's desktop. Also
to allow for a robust system capable of handling queries
and information retrieval we selected Oracle 8.0 database
with Web Server and Java
Development Suite. [Figure 1]

of Data & Graphs.
Understanding the overhead associated
with web server software in addition to the data acquisition software
[LabVIEW 5.01 of National Instruments was the data acquisition software]
we chose two computer systems- DAQ system and Database System.
- DAQ: An
HP-Vectra 300 MhZ system equipped with an RS-232 multiplexer
provided enough power to continously monitor all equipment. Using
Microsoft ODBC driver the DAQ computer continously (or
based on a set interval as provided by operator). This
system was only connected to the Database computer through
TCP/IP and was NOT connected to the corporate intranet.
- Database: HP-Netserver
II was with redundant power supplies and 19 GB hard drive
equipped with Seagate Backup Exec was chosen for the
Oracle 8.0 database. This system was connected
to the corporate intranet, while the DAQ system was only
connected to this server via a second Ethernet card. This
network allowed for engineers to simply view the graphs/reports/
and status of all chambers using their web browsers. The
DAQ System was completely off the network, hence keeping
it away from any traffic or requests that could possibly
slow it down.
