Configuring the Hardware and Installing Windows NT 85
Figure 47. Server Service Tuning
You can specify how much memory is reserved for the operating system indirectly
by specifying how much memory (relatively) to give to server processes.
You have four choices:
1.
Minimize Memory Used: this choice will minimize the memory used for disk
cache and maximize the memory available for the operating system. However,
on file servers, the resulting performance would not be desirable. Therefore,
only use this choice for Windows NT workstations.
2.
Balance: this choice will attempt to balance the use of real memory between
the operating system and the disk cache. This is a good choice for a
non-dedicated server that is also used as a workstation.
3.
Maximize Throughput for File Sharing: this choice will yield the best
performance in the file server environment but will necessitate a significant
amount of swapping in the machine unless you have enough memory in your
system to ensure that both the disk cache and the operating system have
adequate resources.
4.
Maximize Throughput for Network Application: this choice is the
recommended setting for machines used as application servers and database
server. SAP recommends in its installation manuals that you use this setting
for your application and database servers.
2.13.8 Installing Windows NT Driver for the ASMA Card
• To install the Windows NT driver for the ASMA card, insert the Advanced
Systems Management Adapter configuration update utility and device driver
diskette in the floppy drive.
• Please use the ASMA configuration diskette from the ASMA card installation
steps from 2.11, “Configurating the Advanced System Management Adapter”
on page 51. These installation steps created an SM.INI file on this diskette
which is needed during this driver installation.
• Go to Windows NT command prompt.
• Change to the diskette drive root directory and execute the program
\NT\Setup.exe .
• The program will copy a driver and a library file (DLL) in your Windows NT
system directory and set some registry entries. During the driver installation
you will see messages on your screen like this.
