Known SpectroSERVER Anomalies in
SPECTRUM 6.5
Problem 1: On the Windows NT platform, SPECTRUM may not recognize
NT user accounts because of case-sensitivity even though they exist in the
SPECTRUM User Database.
Solution: Ensure that the SPECTRUM user name and Windows NT
account name are spelled identically and have the same case.
Problem 2: On the Windows NT and Windows 2000 server, the operating
system is optimized to function as a file server by default. This causes the
virtual memory system to give precedence to file cache when deciding
which memory pages are eligible to be paged out. When large files are open
as in the case with large SpectroSERVER and DDM databases, this can
cause all of the available physical memory to be used for file cache. As
available physical memory gets low, SpectroSERVER (as well as other
applications) will have their executable code paged out in favor of
maintaining the file cache. This results in very poor application
performance. In extreme cases, SpectroSERVER itself may shut down with
a low memory error.
Solution: Change the default setting of the Windows paging algorithm.
On the Windows NT Server, change the setting located in:Control Panel->
Network-> Services-> Server-> Properties from “Optimize Throughput
for File Sharing” to “Balance.”
On Windows 2000 Server, change the setting located in: Settings->
Network and Dial-up Connections-> Local Area Connections->
Properties -> File and Printer Sharing for Microsoft Networks->
Properties from “Optimize Throughput for File Sharing” to “Balance.”
Problem 3: The Event Log and Alarm Manager will give you misleading
connection status. If the Archive Manager runs with the wrong landscape
handle, it will correctly generate an orange alarm indicating that no
connection has been established. Yet, the connection status dialog in
Alarm Manager and Event Log is green indicating that they are connected
to the Events Service.
