Chapter 1 - IBM WebSphere MQ

Adapter

This chapter introduces the IBM WebSphere MQ adapter. You can use the adapter

with a Command Server, an Event Server, the Platform API, or with a map in a

map rule.

IBM WebSphere MQ software transports data between applications. For the

receiving application to be able to successfully use data, it (the data) must be

transformed. IBM WebSphere MQ can successfully move data in heterogeneous

computer networks, allowing systems of dissimilar computers to move data to and

from each other. Although data successfully arrives at a target, it often cannot be

used in its native form and must be transformed into a format acceptable for the

receiving application’s use.

NOTE: IBM WebSphere MQ for the NonStop server is only available as server

software.

Overview

The IBM WebSphere MQ adapter works with IBM WebSphere MQ to accomplish the

task of maintaining data compatibility, handling all kinds of data transformations

from the simplest to the most complex. The IBM WebSphere MQ adapter can be

used at either the source or target application, or at both. The adapter for IBM

WebSphere MQ is available as a server adapter to be used with IBM WebSphere

MQ server software.

IBM WebSphere MQ Message Content

The IBM WebSphere MQ message data content can be any content type. Under

some conditions, message data contains a message header known as an IBM

WebSphere MQ Message Descriptor structure. For example, if you use the IBM

WebSphere MQ Link for R/3, the input message data always contains a header

and a header must be created for an output message.

Use the IBM WebSphere MQ adapters to include the message header in the data

using the optional Header adapter command (

-HDR). When the command is

specified for an input message, the message header appears before the message

content. If the command is specified for an output message, the adapter assumes

that the first block of data supplied for the target consists of the appropriate size
