script

 

is

 

located

 

in

 

the

 

\bin

 

directory

 

below

 

the

 

product

 

directory

 

(<ProductDir>).

 

Using

 

a

 

text

 

editor,

 

add

 

the

 

following

 

line

 

as

 

the

 

first

 

line

 

in

 

the

script:

 

export

This

 

line

 

restricts

 

heap

 

memory

 

usage

 

to

 

a

 

maximum

 

of

 

768

 

MB

 

(3

 

segments

 

*

 

256

 

MB).

 

If

 

the

 

process

 

memory

 

grows

 

larger

 

than

 

this

 

limit,

 

page

 

swapping

 

can

 

occur,

 

which

 

can

 

adversely

 

affect

 

the

 

performance

 

of

 

your

 

system.

Set

 

the

 

value

 

of

 

the

 

IPCCBaseAddress

 

property

 

to

 

11

 

or

 

12

.

 

For

 

more

 

information

 

on

 

this

 

property,

 

see

 

the

 

 

 

 

 

UNIX.

 

When

 

the

 

value

 

of

 

this

 

property

 

is

 

true

,

 

a

 

JMS-enabled

 

connector

 

can

 

ensure

 

that

 

duplicate

 

events

 

are

 

not

 

delivered

 

to

 

the

 

delivery

 

queue.

 

To

 

use

 

this

 

feature,

 

during

 

connector

 

development,

 

the

 

connector

 

must

 

have

 

a

 

unique

 

event

 

identifier

 

set

 

as

 

the

 

business

 

object

 

ObjectEventId

 

attribute

 

in

 

the

 

application-specific

 

code.

 

  

When

 

the

 

value

 

of

 

this

 

property

 

is

 

true

,

 

the

 

MonitorQueue

 

property

 

must

 

be

 

enabled

 

to

 

provide

 

guaranteed

 

event

 

delivery.

 

The

 

default

 

value

 

is

 

false

.

 

 

When

 

the

 

value

 

of

 

this

 

property

 

is

 

true

,

 

the

 

adapter

 

runtime

 

will

 

mark

 

the

 

incoming

 

ObjectEventID

 

as

 

a

 

foreign

 

key

 

for

 

flow

 

monitoring.

 

This

 

property

 

is

 

only

 

valid

 

if

 

the

 

BrokerType

 

property

 

is

 

set

 

to

 

ICS.

 

The

 

default

 

value

 

is

 

false

.

 

 

If

 

the

 

connector

 

experiences

 

an

 

error

 

while

 

processing

 

a

 

message,

 

it

 

moves

 

the

 

message

 

(and

 

a

 

status

 

indicator

 

and

 

description

 

of

 

the

 

problem)

 

to

 

the

 

queue

 

specified

 

in

 

the

 

FaultQueue

 

property.

 

The

 

default

 

value

 

is

 

<CONNECTORNAME>/FAULTQUEUE

.

 

 

The

 

jms.FactoryClassName

 

property

 

specifies

 

the

 

class

 

name

 

to

 

instantiate

 

for

 

a

 

JMS

 

provider.

 

This

 

property

 

must

 

be

 

set

 

if

 

the

 

value

 

of

 

the

 

DeliveryTransport

 

property

 

is

 

JMS

.

 

The

 

default

 

is

 

CxCommon.Messaging.jms.IBMMQSeriesFactory

.

 

 

The

 

jms.ListenerConcurrency

 

property

 

specifies

 

the

 

number

 

of

 

concurrent

 

listeners

 

for

 

the

 

JMS

 

controller.

 

It

 

specifies

 

the

 

number

 

of

 

threads

 

that

 

fetch

 

and

 

process

 

messages

 

concurrently

 

within

 

a

 

controller.

 

This

 

property

 

is

 

valid

 

only

 

if

 

the

 

value

 

of

 

the

 

jms.OptimizedTransport

 

property

 

is

 

true

.

 

The
