Hi,
What are the main advantages/differences of using MQSeries server against MQSeries client, I know that:
- Clients don't provide synchronous, whereas MQSeries server is asynchronous
- Clients connect to a queue manager, which might resides locally or remotely.
- It is more expensive to buy MQSeries server
- There is nothing to admionister on a client machine, whereas on the MQSeries server machine, you will need to look after queue manager and its objects.
What I am not sure of is that, does mqseries client provide assured delivery of messages?

There is a section in the Clients manual that gives a discussion on why you might want to use clients. As far as your points:
- An MQSeries client application requires a synchronous connection to the qmgr. If this connection goes down, your program becomes responsible for the messages.
- You can use a client connection to a qmgr that is either local (on the same machine) or remote (on a different machine).
- MQSeries servers are more expensive. However, they do give you the benefit of being able to store messages.
- The client does have some administration in that you have to take care of either the client connection table or the use of the MQSERVER environment variable. |

The other thing to keep in mind is that you can't just buy the client.
Clients have to connect to a server somewhere. |
