How to communicate with TIBCO EMS Server using Loadrunner?

Question

I am new to TIBCO and trying to communicate with EMS Server using loadrunner.

The communication between the client and server takes place generally over TCP.

I have following details with me:

• URL: tcp://someserver.com:port
• Username:
• Password:
• Queue Connection Factory: QueueConnectionFactory

Did any one try publishing messages on EMS Server with Loadrunner.

Please suggest on how can I start scripting?

Answer 1

I believe you should be using tibjmsnaming:// not tcp. and Keep the needed JMS/EMS libraries available in the Path.

you should be using WebServices template. I remember publishing messages to Load runner long back.

Answer 2

You have a number of paths to any JMS compliant target. Some use web services protocol. My preference is a small Java template virtual user leveraging the appropriate connection factory elements. Very likely your queue solution also has a C level interface which could be incorporated into a C template virtual user. You have options for a virtual user developed in Visual Studio (see documentation, advanced topics) using C++/C#/VB. If you have an existing client you may even be able to record a "push" and a "pop" from the queues with Winsock and manipulate the appropriate buffers for exercise - I have used this path with MQ in the past.

So, lots of options based upon your skills, your licensed virtual user types, etc...

After searching it on google and trying out with different protocols, i found out a simple way to publish message on EMS server.
As EMS is an extension of JMS(java messaging service) we have to use jms protocol to communicate with EMS.
Using a java vuser in VUGEN is the best option.
Below is the code you can paste in actions.java file.

public int action() throws Throwable {
        String serverUrl = "tcp://localhost:7222";
        String userName = "admin";
        String password = "admin";

        String queueName = "your queue name";

        try {
        System.out.println("Sending JMS message to server " + serverUrl + "...");

        QueueConnectionFactory factory = new TibjmsQueueConnectionFactory(serverUrl);
        QueueConnection connection = factory.createQueueConnection(userName, password);
        QueueSession session = connection.createQueueSession(false, javax.jms.Session.AUTO_ACKNOWLEDGE);

        // Use createQueue() to enable sending into dynamic queues.
        Queue senderQueue = session.createQueue(queueName);
        QueueSender sender = session.createSender(senderQueue);

        /* publish messages */

        TextMessage jmsMessage = session.createTextMessage("your message");
        //String text = (String) data.elementAt(i);
        //jmsMessage.setText(text);
        sender.send(jmsMessage);
        System.out.println("Sent message!");


        connection.close();
        } catch (JMSException e) {
        e.printStackTrace();
        System.exit(0);
    }
        return 0;
}//end of action
