Software AG introduces version 6.5 of the webMethods WebSphere MQ Adapter.
This is a major release of the adapter that provides several features to help
you manage your WebSphere MQ integrations more
easily. The WebSphere MQ Adapter provides seamless
and real-time communication to and from WebSphere MQ
without requiring changes to the WebSphere MQ system.
Now you can leverage your existing WebSphere MQ
information flow to collaborate with your customers, suppliers, and other
business partners via webMethods Fabric.
The WebSphere MQ
Adapter now simplifies the management of your large scale WebSphere
MQ integrations by allowing you to configure a single listener that can listen
to multiple queues on a queue manager, reducing the number of adapter
connections and listener notifications that must be managed in your
environment. This release of the adapter introduces a new type of listener
called a Multi-Queue Listener, which you configure to listen to multiple queues
on a single queue manager. For each queue you define in a Multi-Queue
Listener's adapter connection, the adapter will create a child listener to
receive MQ messages. When you manage a Multi-Queue Listener, all of the child
listeners associated with it inherit its properties.
For example, any adapter notifications associated with the Multi-Queue Listener
are automatically associated with all of the child listeners, greatly reducing
the number of notifications you must configure.
The adapter provides a new adapter service
called the InquireQueueManager service, which enables
you to inquire properties of a WebSphere MQ queue and
queue manager. The output of this service provides useful information about the
properties of queues, such as the current depth of the queue, as well as
properties of queue managers, such as the queue manager's dead letter queue
name and connection count. Because these properties are returned in the output
of the adapter service, this service enables you to design Java or flow
services and make logical branches based on the data returned by the service.
The adapter provides a new adapter service
called the PCFCommand service that enables you to
issue Programmable Command Formats (PCF) commands directly from your Java and
flow services. You can use this service to issue PCF commands to fetch
information about Websphere MQ objects (such as queue
managers, queues, and channels), and also to perform administrative functions
on these objects.
This feature enables the Put and RequestReply adapter services to send messages to a queue
that is defined on a remote queue manager even though the adapter is connected
to a local queue manager, without having to define a remote queue on the local
queue manager. This feature makes it possible to send data to remote
"Reply To" queues and "Reply To" queue managers, and is
also helpful in conserving the number of connections opened on multiple Websphere MQ servers.
The adapter now enables you to add
user-defined fields to the JMSProperties header, as
well as to add user-defined headers in the Get, Peek, Put, and RequestReply services, and Listener Notifications.
The webMethods WebSphere MQ Adapter 6.5 is compatible with the webMethods WebSphere MQ Adapter
6.0 and 6.0 SP1. That is, you can use the webMethods WebSphere MQ Adapter 6.5 to run or edit services and
listeners you generated using the WebSphere MQ
Adapter 6.0 and 6.0 SP1.
For a list of all the changes and issues
resolved since the last release, see the readme file for webMethods
WebSphere MQ Adapter on the Software AG Documentation
Web site at http://documentation.softwareag.com/ or in the directories in which
you installed webMethods WebSphere
MQ Adapter 6.5.
For information about previous releases of
the webMethods WebSphere MQ
Adapter, see the release notes for those releases, below.
The webMethods WebSphere MQ Adapter supports WebSphere
MQ 5.1, 5.2, 5.3, and 6.0.
For a complete listing of the versions of WebSphere MQ and of webMethods
Integration Server with which the adapter works, see the webMethods WebSphere MQ Adapter
Installation and User’s Guide 6.5.
The webMethods WebSphere MQ Adapter provides seamless and real-time
communication to and from the WebSphere MQ system
without requiring changes to the WebSphere MQ system.
Now, companies can leverage their existing WebSphere
MQ information flow to collaborate with their customers, suppliers, and other
business partners via the webMethods integration
platform.
For example, you can retrieve a purchase
order from a WebSphere MQ server and route the
purchase order to a supplier over the Internet. Additionally, you can query
order status information against suppliers' extranets and deliver the
information to a back-end system through the WebSphere
MQ server.
The WebSphere MQ
Adapter enables you to establish and manage connections to your WebSphere MQ queue managers. Connections, connection pools,
and sessions are fully managed by the adapter. Through these connections you
can create and run your WebSphere MQ integrations.
When developing your integrations, you use
the adapter and its webMethods Developer screens to
view WebSphere MQ queues. From the list of queues,
you select those on which you want to perform operations.
The WebSphere MQ
Adapter provides service templates for interactions with the WebSphere MQ queue managers and queues. This makes it easy
to develop adapter services to interact with WebSphere
MQ.
Service templates represent specific WebSphere MQ operations. For example, a WebSphere
MQ Adapter service that puts a message on a queue is based on the Put service
template included with the adapter. You can create specific adapter services
using the templates and invoke them from your integration flows.
The WebSphere MQ
Adapter provides the ability to generate adapter services that implement the
following WebSphere MQ operations:
|
Put |
Opens a session to a WebSphere MQ Queue Manager and delivers a message to a specified queue. |
|
Get |
Opens a session to a WebSphere MQ Queue Manager and retrieves a message from a specified queue. |
|
Peek |
Opens a session to a WebSphere MQ Queue Manager and retrieves a copy of a message without removing the original message from a specified queue. |
|
Request/Reply |
Opens a session to a WebSphere MQ Queue Manager. This service delivers a message to a specified queue and retrieves a corresponding response from the sent message. |
The WebSphere
MQ Adapter provides listeners and listener notifications to perform the
following functions:
A listener continually
monitors a queue for messages. When a message appears on a queue, the listener fetches
the message, based on the filter criteria that you selected when you configured
the listener. The listener passes the message to the listener notification.
Unlike the Put and Get adapter services, you never invoke a listener directly
from a service or client. Instead, a listener is a real-time process that you
configure, enable, and disable using the Administrator.
A listener notification works in conjunction
with a listener to filter and process messages in the WebSphere
MQ Adapter. When a listener detects a message on a queue, the listener performs
a "Get" to retrieve the message, and passes the message to the
listener notification. The listener notification receives the message and
performs an additional filter on the message, based on the filter criteria that
you selected when you configured the listener notification. The listener
notification processes the message either synchronously or asynchronously.
The webMethods WebSphere MQ Adapter 6.0 is a new adapter and is not
compatible with integrations built using the webMethods
WebSphere MQ Adapter 3.0. That is, you cannot use the
webMethods WebSphere MQ
Adapter 6.0 to run or edit services you generated using the earlier WebSphere MQ adapters, and vice versa.
However, you can run the webMethods
WebSphere MQ Adapter 6.0 on the same Integration
Server with earlier webMethods WebSphere
MQ adapters.
