JMS is a standard that defines how you can access enterprise messaging systems from Java programs. Say you want to send data from your application to a single queue. Adjust accordingly if you are using your own objects, or go to Ready, Set, Connect to get started.
If not, you need to set up authorisation on the queue manager to accept connection from the application through a named channel and the application has to be authorised to put and get messages to and from the queue.
If you already have a JMS application but want some help with performance or debugging, try this tutorial. On Linux, depending on which package you downloaded you need to run it to install. For example, if you downloaded ibm-java-sdk Lets get the sample from GitHub, save it on your local machine and look through some of the key JMS constructs and where you can add the host, port, channel and queue details so your sample can connect to the queue manager.
Replace the host, port and app password variables to match your queue manager configuration. Create the connection factory programatically by using WMQConstants parameters. Your application can use these extensions to create connection factories and destinations dynamically, at runtime, and set MQ specific object properties.
You need to include declarations for the ibm. The following MQ Constants properties are used by the connection factory to create a connection when the application is run:. In production, you would use a JNDI store to look this information up. An additional property for the connection factory object is connection mode.
Applications can connect to the queue manager in client or bindings modes. Use the connection factory to create the context and use the context to create the destination. Use the context to create the producer. The producer sends the message using the destination to put the message to the right queue:. Use the context to create the consumer.
The consumer uses the destination to receive the message from the right queue. To compile the sample, go to your MQClient directory. Use javac to compile your application. If you want to make sure your JMS application is going to perform reliably and well, have a look at this tutorial. This tutorial is based on JMS 2. Earlier versions can still be used to support backward compatibility. Check out the JMS 2.
How can get the queue depth?
JMS takes messaging objects that are common to different messaging providers and defines them in a way that can be reused regardless of the JMS messaging provider. It also provides facilities for encapsulating concepts that are specific to each provider, in a way that can minimise how much a developer needs to know about how each messaging provider works. Figure 1. JMS Administered objects are connection factory and destination.
The objects or interfaces that JMS 2. Queue — administered object that encapsulates the identity of a message destination for point to point messaging. Topic — administered object that encapsulates the identity of a message destination for publish subscribe messaging. Destination — the common supertype of Queue and Topic objects. Connection factory — administered object used by a client to create a connection. Figure 2. In production environments, your JMS administered objects would access information about the objects on the provider MQ server side, from a JNDI store that is separate from the client and the messaging server.
Your application would not use each MQ parameter directly as this means it would be tightly coupled to the queue manager, channel and the queue. Each time something changed with any of those, you would have to make changes to your application too.Monitoring a queue on WMQ.
This is a kind of very basic activity on an MQ infrastructure. And there are plenty of sample programs written in Java and other languages available free on internet to get a queue depth of a particular queue. The program here is of no much difference. Its a sample utility to monitor a queue for a particular time period on particular interval and capture the metrics in to an excel sheet for easy reference.

In production, we have a good size and number of logs. However, it is a busy queue manager and the logs can overwrite in a matter of hours in typical operation. In development, log numbers and sizes are much more limited. Also, I've never seen enqueue rates this high. We saw a CPU spike in development, but no other apparent impact to system resources.
The logs overwrote themselves within the same minute, though. Two questions: 1. We've seen posts about rates much higher than this, but we've never had such rates at our site before.

Can anyone help in doing the code in java of getting the depth of the queues. I want to write a jsp to read the queue names and their depth while running the report. How do I do that? If I had to do that I'll expose it in a Mbean. For monitoring and checking the status of resources, such as queue depths, there are a couple of options. You can access these Mbeans through wsadmin or programmatically. Secondly, you can use the traditional WMQ administration utilities, such as runmqsc or MQExplorer, to look at queues and other resources.
If you do use these utilities, it is essential that you do not make any configuration changes to the Application Server queue manager and queues. These resources are under the control of Application Server. Making changes to these resources using the MQ utilities results in a non-functioning configuration. How are we doing?

Queue Depth - JMS. Hi, Is there any way by which we can find Number of messages available in the Queue at a given point of time Programatically. Steve Wink. This is a notable omission from the JMS spec. You can get the depth by browsing every message in the queue, but obviously this is pretty wasteful.
Some of the underlying queueing systems e. Trimoorthy Kotte. Apologies, I missed out the text last time I was posting the reply. You might have similar APIs available in other app servers. Babu Rengarajan. I tried way of getting queue depth, it works locally where no user name and password is given on was server.
When i applied this program for production was server where user name and password has been given.
It is given authentication problem. Joe Hepp. Here is how we do the browsing method to get a count via JMS. It is wasteful but this is used in a batch retry situation so we aren't concerned with performance.
