| What would the MQ'ers out there say are the main differences between MQSeries Client and MQSeries Server. We have clients who want to use MQ client because it is FREE. |

How about:
- no asynchronous messaging between systems
- no /XA resource coordination with RDBMSs
- if OS/390 is the server, a significant charge for the MQ CAF
...
I'll leave it up to the others to add more.
Clients may be an OK choice in a LAN environment with little network latency/high availability, definitely THE choice for MQ functionality at the end user's desktop. It all depends on what applications you want to base on the MQ infrastructure. I don't think there is a hard and fast rule that you could apply.
Don't you like this answer?  It all depends.
 G'day to down under,
Stefan

Hi,
I would like to have just a comfirmation.
I have to do an MQseries client application that
receive messages and maybe send some ack or
error messages to a remote server.
"MqSeries client" is the only thing I need ?
Is it really free ?
Is it really free ? (to be sure)
Are there limitations to use only these clients components ?
NB : these questions may seem stupid
but I just want to be sure that it's free
(it's very very surprising...) and that there
no trap...
thanks |

| If you want to use the MQSeries client, you'll need to connect it to an MQSeries queue manager. You'll have to pay for the queue manager license. |

Thought this info might be of value to you:
Using MQSeries client is an efficient way of implementing MQSeries messaging and queuing. You can have an application that uses the MQI running on one machine and the queue manager running on a different machine, either physical or virtual. The benefits of doing this are:
· There is no need for a full MQSeries implementation on the client machine; for example, it could be a DOS, a Windows 3.1, or a Windows 95 platform.
· Hardware requirements on the client system are reduced.
· System administration requirements are reduced.
· An MQSeries application running on a client can connect to multiple queue managers on different systems.
· Alternative channels using different transmission protocols may be used.
What applications run on an MQSeries client? The full MQI is supported in the client environment and this enables almost any MQSeries application to be relinked to run on an MQSeries client. Link the application on the MQSeries client to the MQIC library, rather than to the MQI library. The exceptions are:
· An application that needs syncpoint coordination with other resource managers.
· Get(signal) on MVS/ESA is not supported.
Note: An application running on an MQSeries client may connect to more than one queue manager concurrently, or use a queue manager name with an asterisk (*) on an MQCONN or MQCONNX call. The application will have to be changed to link to the queue manager libraries instead of the client libraries.
WebSphere MQ Integrator client applications are applications that use the services provided by the message flows deployed within one or more brokers in the broker domain. These applications can use one of two techniques for gaining access to the broker’s services:
An application can use an MQSeries client connection. You can use all the MQSeries clients that are supported by MQSeries Version 5.1 or later. This allows you to connect applications running in a wide variety of environments into your broker domain. An application running on the same system as the queue manager to which it connects can also use a client connection. An application running on the same system as a broker can use a local connection to the queue manager that hosts that broker.
For more details about applications, putting and getting messages, and the use of MQSeries clients, see MQSeries Clients and the MQSeries Application Programming Guide. WebSphere MQ Integrator does not impose any particular conditions or restrictions on applications. |

Those of you who don't know where to download free client, here is the link:

Thanks all,
What are the different kinds of licences (server/queue manager....) ?
Where can I found and get them ?
If I've understood, it will depend on the client
architecture I will choose.
On the client machine I can have
- queue manager and queue
- queue
- nothing (everything on the server)
Are there other kind of architecture ?
Where can I find the advantages/defaults of theses client architectures ?
thanks |

Right answer is nothing.
Simplified, MQ client is only an API: libs & headers. |

| wouldn't another option be multiple brokers? |
