SpectroSERVER
SPECTRUM Installation/Uninstallation Programs
Known Anomalies: SpectroSERVER
Item Description Solution
1 On the Windows NT/2000 server, the
operating system is optimized to
function as a file server by default. This
causes the virtual memory system to
assign precedence to the file cache when
deciding which memory pages are
eligible to be paged out.
When large files are open, such as with
SpectroSERVER and DDM databases, all
of the available physical memory is
assigned to the file cache.
As available physical memory is
allocated, SpectroSERVER, as well as
other applications, have their executable
code paged out in favor of maintaining
the file cache. This results in poor
application performance. In extreme
cases, SpectroSERVER shuts down with
a low memory error.
Change the default setting of the
Windows paging algorithm using one of
the following methods:
Windows NT Server
1. Select Control Panel > Network >
Services > Server > Properties.
2. Change property from Optimize
Throughput for File Sharing to
Balance.
Windows 2000 Server
1. Select Settings > Network and
Dial-up Connections > Local
Area Connections > Properties >
File and Printer Sharing for
Microsoft Networks >
Properties.
2. Change property from Optimize
Throughput for File Sharing to
Balance.

Item Description Solution
1 When you install SPECTRUM on Windows
NT/2000 with a user name containing a
space (for example, NT SPECTRUM) the
installation appears to run successfully
until the very end, then you receive a
message similar to the following:
sed: Unterminated ‘s’ command
You could possibly receive this message
several times.
Avoid spaces in SPECTRUM user names.
