[firebase-br] Servidores win 2000e 2003 - parte 4

[Valdir Marcos]

Pessoal, bom dia.

Na documentação do IB6 e na internet eu achei um conjunto de informações sobre o FB em servidores, em especial, sobre o Win NT.
Alguém poderia me dizer se essas informações que passarei nas próximas mensagens são válidas também para os servidores win 2000 e 2003?

Obrigado,

Operating system configuration

After you have equipped your server hardware appropriately, you should spend time

tuning your operating system for server performance.

Disabling screen savers

Screen savers can have a serious impact on the performance of a server. Because servers

are often set aside in a machine room, it's easy for the performance impact of a screen

saver to be overlooked. Screen savers demand a surprising amount of CPU resources to

run, and these programs run continuously, 24 hours a day.

Screen savers are evasive in their ability to disappear when a database administrator logs

in to the console to diagnose a mysterious drop in performance. The server seems

responsive to the DBA as soon as she touches the server, but the speed degrades soon

after she leaves the server.

Not all screen savers have the same performance cost. The Windows NT OpenGL screen

savers perform continuous floating-point computations to draw three-dimensional

shaded shapes in real time. They demand up to 90% of the system CPU, and cause

InterBase and other services to slow to one-tenth their normal speed.

The Windows Marquee screen saver is one of the least demanding ones, especially when

it is configured to pass text across the screen slowly. Some system administrators like to

configure a Marquee on each screen in the machine room, to display the respective

machine's hostname. This becomes a machine-name label, in raster form.

A screen saver can also be entertainment, but these should be reserved for workstations.

A server in a machine room should be unattended, not used as a workstation.

If you must have phosphor burn protection for a monitor that you leave on, get an Energy

Star approved monitor that has a power conservation mode. This mode blackens the

screen after a configurable period of idleness. This not only protects against phosphor

burn, but it conserves power. This is like a simple black screen saver, but it is handled by

the electronics of the monitor, instead of by software.

The best option is to simply turn off the monitor when you aren't using it. This saves the

phosphors, saves electricity, and decreases the amount of heat in the machine room.
