In

look

 

for

 

the

If

change

 

the

create

 

a

set

The

value

 

for

 

this

 

key

 

is

 

1

.

  

This

 

is

 

good

 

for

 

a

 

drive

 

that

 

will

 

contain

 

relatively

 

a

 

few

 

large

 

files.

 

Other

 

options

4

Unfortunately,

 

Microsoft

 

doesn't

 

give

 

any

 

clear

 

guidelines

 

as

 

to

 

what

 

distinguishes

 

Medium

 

from

 

Larger

 

and

 

Maximum

 

levels

 

of

 

files.

 

Suffice

 

it

 

to

 

say,

 

if

 

you

 

plan

 

to

 

store

 

lots

 

of

 

files

 

on

 

your

 

workstation,

 

you

 

may

 

want

 

to

 

consider

 

a

 

value

 

of

 

3

 

or

 

4

 

instead

 

of

 

the

 

default

 

value

 

of

Setup

 

If

 

you

 

set

 

up

 

your

 

Object

 

Directory

 

backup

 

tool,

 

make

 

sure

 

it

 

is

 

not

 

running

 

too

 

many

 

times

 

a

 

day

 

because

 

the

 

in

 

between

 

time

 

will

 

be

 

too

 

short.

 

This

 

will

 

cause

 

the

 

tool

 

to

 

run

 

constantly

 

causing

 

overload.

 

Do

 

not

 

use

 

the

 

object

 

change

 

tracker

 

in

 

big

 

database.

 

It

 

will

 

decrease

 

the

 

database

 

speed

 

about

 

100%!

   

 
 

Anti

Virus

 

Scanner

 

It

 

is

 

not

 

necessary

 

to

 

use

 

a

 

virus

 

scanner

 

on

 

the

 

database

 

(SBDATA).

 

Most

 

of

 

the

 

data

 

is

 

encrypted,

 

so

 

there

 

is

 

nothing

 

to

 

be

 

scanned

 

and

 

scanning

 

will

 

reduce

 

much

 

of

 

the

 

performance.

  

Switch

 

off

 

any

 

scanning

 

of

 

the

 

SBDATA

 

on

 

the

 

EEPC

 

Database

 

server.

 

Also,

 

exclude

 

the

 

SbDbServer

 

executable

 

from

 

scanning.

 

 

Also

 

if

 

your

 

Anti

 

Virus

 

program

 

has

 

high

risk/low

risk

 

process

 

detection

 

marking

 

all

 

the

 

EEM/EEPC

 

main

 

executables

 

on

 

the

 

server

 

as

 

low

 

risk
