Name

 

Indexing

 

(DBCFG.INI)

 

Name

 

indexing

 

should

 

be

 

enabled

 

on

 

all

 

databases

 

especially

 

those

 

with

 

over

 

1000

 

endpoints

 

or

 

users.

 

It

 

will

 

be

 

noticeably

 

faster

 

and

 

improve

 

performance.

  

 

To

 

do

 

this,

 

create

 

a

 

basic

 

text

 

file

 

called

 

DBCFG.INI;

 

file

 

and

 

copy

 

it

 

to

 

the

 

SBDATA

 

folder

 

(assuming

 

default

 

location

 

for

 

Object

 

Directory)

 

and

 

edit

 

as

 

below:

 

 
 

Warnings

 

 

Do

 

not

 

use

 

Single

 

File

 

mode

 

as

 

shown

 

in

 

the

 

options

 

below.

 

It

 

can

 

be

 

used

 

for

 

small

 

databases

 

but

 

not

 

recommended

 

as

 

it

 

can

 

be

 

much

 

slower.

 

 

The

 

Find

 

function

 

does

 

not

 

use

 

the

 

name

 

cache

 

and

 

therefore

 

searches

 

the

 

complete

 

database

 

sequentially.

 

 

DBCFG.INI

 

Sections

 

are

 

added

 

defined

 

by

 

[]

 

with

 

the

 

options

 

in

 

each

 

section

 

added

 

as

 

below.

 

[NameIndex]

 

Enabled=Yes

 

This

 

must

 

be

 

set

 

to

 

"Yes"

 

for

 

the

 

name

 

index/caching

 

to

 

be

 

used

 

by

 

programs

 

running

 

for

 

this

 

directory.

 

LockTimeout=3000

 

This

 

option

 

controls

 

how

 

long

 

the

 

process

 

will

 

retry

 

access

 

to

 

the

 

index

 

file

 

if

 

it

 

is

 

locked.

 

You

 

can

 

decrease

 

this

 

value

 

if

 

the

 

administrator

 

experiences

 

long

 

waiting

 

times

 

during

 

installation,

 

for

 

example

 

 

1000,

 

however,

 

only

 

in

 

databases

 

smaller

 

than

 

5000

 

systems,

 

otherwise

 

you

 

find

 

the

 

number

 

by

 

multiplying

 

the

 

number

 

of

 

users

 

or

 

systems

 

in

 

the

 

database

 

by

 

0.6.

 

 

Example:

 

If

 

the

 

number

 

of

 

users

 

in

 

the

 

database

 

is

 

10,000,

 

the

 

Locktimeout

 

should

 

be

 

6000.

 

The

 

default

 

value

 

is

 

3000.

 

The

 

value

 

is

 

in

 

100ths

 

of

 

a

 

second.

 

In

 

case

 

of

 

multiple

 

servers,

 

the

 

timeout

 

can

 

exceed

 

due

 

to

 

many

 

simultaneous

 

connections.

 

In

 

that

 

case

 

the

 

value

 

needs

 

to

 

be

 

increased

 

to

 

30000.

 

 

LockSleep=10

 

This

 

option

 

controls

 

how

 

long

 

the

 

process

 

will

 

sleep

 

(wait)

 

before

 

re

trying

 

opening

 

a

 

locked

 

file.

 

The

 

value

 

is

 

in

 

1000ths

 

of

 

a

 

second.

 

In

 

case

 

of

 

multiple

 

servers,

 

the

 

locksleep

 

might

 

need

 

to

 

be

 

increased

 

due

 

to

 

many

 

lock

 

timeouts.

 

In

 

that

 

case

 

the

 

value

 

needs

 

to

 

be

 

increased

 

to

 

100

 

or

 

even

 

1000.

 

 

HashCount=16

 

This

 

option

 

controls

 

how

 

many

 

"buckets"

 

the

 

hash

 

of

 

the

 

name

 

is

 

split

 

into.

 

It

 

should

 

be

 

between

 

1

 

and

 

256

 

(default

 

16).

 

Generally,

 

a

 

good

 

value

 

can

 

be

 

calculated

 

by

 

taking

 

the

 

square

 

root

 

of

 

the

 

number

 

of

 

users.

 

However,

 

for

 

optimal

 

performance

 

this

 

value

 

should

 

be

 

tuned

 

by

 

testing.

 

 

MinEntrySize=16

 

 

This

 

is

 

the

 

minimum

 

space

 

to

 

allocate

 

per

 

object

 

name

 

in

 

the

 

index

 

file.

 

The

 

default

 

of

 

16

 

is

 

a

 

good

 

value

 

if

 

the

 

names

 

do

 

not

 

exceed

 

16

 

characters.

 

You

 

do

 

not

 

need

 

to

 

specify

 

the

 

value

 

if

 

the

 

names

 

do

 

not

 

exceed

 

16

 

characters.
