Hi,

I worked with regular WebSphereMQ Server and know all the concepts. I would like to use the internal MQ Server provided with WebSphereMQ Application Server 5.1. What is the difference between this internal MQ Server and regular MQ Server?

I just need to create a Queue and post messages onto that with in WebSphere Appserver and create Message Driven Beans to pick them and process.

Can anyone explain how this internal MQ Server works?

I saw crtmmqm.exe command in the bin directory which helps to create a Queue Manager, but I didn't see runmqm to run on it for creating Queues.

Thanks,
Bharat

The embedded JMS is a stripped down version of the full MQ product. Some of the utilities that you would use to administer full MQ aren't shipped since you are supposed to be using WAS to administer it. When the AppServer starts up, if you have your JMSServer set to started, you'll get your qmgr (and broker) started. You'll see entries for both in your SystemOut.log.

In order to define queues, you use the list box that is under your server's JMS Server component. You put the name in the box and WAS sees to it that the queues are created.

As far as MDBs are concerned, you'll need to define WebSphere JMS resources for your QCF/Q or TCF/Topic. You then create a listener port that points to these, and deploy your MDB against this port.

Hope this helps.

Also, never, never, never use the crtmqm or dltmqm command to create and delete the qmgr that is associated with WAS. There is more to it. There are a couple of scripts (createmq, deletemq) that are supplied that can be used.

WSAD 5.1 adds a third option, the 'MQ simulator', this is a pure java JMS implementation with no persistence, remote queuing or clients. It runs in the WAS JVM, and can only be accessed within the WAS JVM. It was desgined to be lightweight for unit testing purposes, and cannot be used within WAS (only available within WSAD test environments).
