Known Anomalies: SpectroSERVER
Item Description Solution
1 On Windows NT, SPECTRUM does not
recognize user accounts because of
case-sensitivity, even when the user
accounts exist in the SPECTRUM user
database.
Ensure the SPECTRUM username and
Windows NT account name are spelled
identically and have the same case.
2 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.
