and values of a valid IBM WebSphere MQ Message Descriptor structure. When the

Header adapter command (

-HDR) is specified, any of the message header

components may be included in mapping rules.

For mapping purposes, definitions for the message descriptors and the IBM

WebSphere MQ Link for the R/3 header are provided in the mg.mtt type tree,

located in the examples\adapters\mq folder.

Transmission Queues

An IBM WebSphere MQ transmission queue is a local queue that stores messages

destined for a remote queue. The messages are forwarded to their destination

queue through a message channel when a communication program and link are

available. The channel provides a one-way link to the remote queue manager.

Messages are queued at the transmission queue until the channel can accept

them. A message channel agent (channel program) that actually transmits the

message must be associated with the transmission queue and the remote queue

manager. When the message has been transmitted, it is deleted from the

transmission queue. The channel definition must specify a transmission queue

name at the transmitting end of the message channel.

The IBM WebSphere MQ adapter supports the definition of transmission queues for

data targets with the Transmission Queue Name adapter command (

-XQN) and

the Transmission Error Queue Name adapter command (

-XEQN).

System and Configuration Requirements

The adapters for the IBM WebSphere MQ messaging system can be installed and

operated in a Windows environment. The adapters must be installed on a machine

running the IBM WebSphere MQ server software.

For general system requirements when using adapters, refer to the Getting

Started book.

This section identifies the requirements to install and run the IBM WebSphere MQ

adapters in an environment running IBM WebSphere MQ server software.

In addition to the general requirements detailed in the Getting Started book, the

following are requirements to install and run the IBM WebSphere MQ messaging

adapter:

• Language Environment release 1.5 or higher

• Three tracks of disk space for the load library
