Page 2 Configuration and Tuning of Sybase System 11 for Microsoft Windows NT on Compaq Servers
administrative tasks for that domain. This leaves all of the server resources available for running
Sybase SQL Server. This is the optimal system to install and run Sybase SQL Server. As a
Windows NT Workgroup server, the management of the entire network, users, and shared
resources is on a per system basis. The throughput of the Sybase SQL Server depends on the
level of requests from other users on the network.
To receive optimal performance of Sybase SQL Server on your Windows NT network, ideally use
four servers. The first server would be configured as the Primary Domain Controller with
Windows Internet Name Service (WINS), Dynamic Host Configuration Protocol (DHCP), and
Gateway system. This system would incur all of the overhead of user logins, network gateway
functions and user permissions. The second server would be configured as the Backup Domain
Controller. The third server, configured as a server participating in a Windows NT Domain,
would be dedicated as the Sybase SQL Server. The fourth server, also configured as a server
participating in a Windows NT Domain, would provide shared file and print services.
For additional information on Domain Controllers, refer to the Windows NT Server, Concepts
and Planning Guide.

System Processor Planning

The objective of this section is to outline the configurations of the Compaq ProLiant Family of
Servers and to provide some performance information necessary to determine the best
configuration for your environment. As is the case throughout the document, certain level of
experimentation and internal performance testing in your own environment can be expected.

UniProcessor and MultiProcessor Support from Compaq

Windows NT utilizes different versions of the following files for single processor and multiple
processor systems:
HAL.DLL
KERNEL32.DLL
NTDLL.DLL
NTOSKRNL.EXE
WINSRV.DLL
The Windows NT installation program automatically selects the correct versions of these files
according to the number of processors installed. However, if you upgrade your system from one
system processor to two or more, you must install the multi-processor support files
the SETUP.CMD file on the Windows NT SSD from Compaq

Processor Scalability

This procedure is not necessary if you already have a MultiProcessor configuration and you add another
processor.

The Compaq Support Software Diskette for Windows NT 3.5x (NT SSD) contains the latest drivers and
utilities that enable you to take advantage of specific capabilities offered on Compaq products. Always
make sure you have applied the latest available NT SSD. You can verify the currently installed versions
of these files via the File Manager, Properties option.
