Server software requirements
• Windows NT Server 4.0 with
Service Pack 6a or
• Windows 2000 Server with
Service Pack 2
• Microsoft TCP/IP network
protocol
• Microsoft Internet Explorer 4.01
or later (for admin client only)
• Internet Information Server
version 3 or greater (IIS is inte-
grated into Windows 2000
Server but has to be installed
separately for Windows NT)
• Oracle 8i Standard Edition
version 8.1.7 (included with
ChemStore C/S server software)
Database size
The database size is selected at
installation time and should be
given careful consideration as
this will affect the total number
of runs which can be accessed
online and the frequency of
archive/dearchive operations.
Archive with delete (to recover
run space in the database) or
dearchive operations (to access
run data online). At installation
time you can either select from
the preconfigured databases con-
figurations listed in table 3, or
have a customized configuration.
Database Approx. Database
configuration no. of runs size
small £ 7500 4 GByte
medium £ 25000 10 GByte
large > 25000 40 GByte
Table 3
Database configurations
vary based on the size of the data-
base selected at installation time
and the number of concurrent
connections (the number of active
instruments acquiring samples to
the database and Agilent Chem-
Store C/S review clients) and the
backup requirements for the serv-
er database. Table 2 shows three
recommended server configura-
tions. In a very small networked
installation with less than three
clients and no need for advanced
security using RAID, the Chem-
store C/S Oracle database can
also run on a high-end PC using
Microsoft Windows NT server
software as operating system.
Note:
Planning the server disk configu-
ration is very important:
12 GByte (for small database) to
54 GByte (for large database)
hard disk, RAID 5 configuration is
recommended. Using a RAID 5
hard disk configuration (redun-
dancy and striping) yields less
free hard disk space than RAID 0
(no redundancy). For example, 3
disks of 9 GByte each using RAID
5 yields 18 GBytes while using
RAID 0 yields 27 GByte. RAID 5 is
recommended for maximum per-
formance and protection of your
data. For backup operation of the
database, the required disk space
must be duplicated, that is a 54
GByte RAID 5 configuration
should have an additional 54
GByte of disk space available for
database backup. When calculat-
ing server memory requirements,
calculate 8 MB of additional mem-
ory for each Agilent ChemStore
C/S client. For more details on
setup and configuration of the
server, please refer to the Agilent
ChemStore C/S Installation
manual.
