This is a relatively new example of how to use JMeter with WebSphere MQ. This approach is a clever way of inserting messages into MQ using a JMS sampler (point to point) with a JNDI binding within MQ.
I had not heard of this approach before and am sure it will ...

Recently had a requirement to construct a LoadRunner harness that could sftp files (over ssh) to and from remote servers. As some of the harnesses were already written in Java (for loading of JMS queues) it made sense to use a Java Vuser to achieve the result required.
A work colleague ...

This is a short post on how to establish JDBC connectivity to a MySQL database when using the Java Vuser type within LoadRunner. Stuart describes a situation in which you might want to do this here. I'm not sure why but the example code is missing from his site, so ...

The following scripts are examples on how to generate load for the BEA WebLogic implementation of JMS. Specifically I demonstrate how to place messages on a queue and how to publish messages to a topic using a Java Vuser within LoadRunner.

Am really starting to enjoy the power and portability of using Java in my load testing efforts, especially when the environments in which you work are often limited in terms of tool sets you're allowed to use. For example the current Solaris environment I work in doesn't have a C ...

When load testing MQ you are no doubt going to need to be able to monitor queue statistics in terms of how many messages have been enqueued and dequeued within a given timeframe. You can use native runmqsc commands to query queues in order to find current queue depths but ...

Recently I wrote a test harness that had a 'discovery' mode. That is, given a target service level agreement (SLA), what transaction pacing or throughput did the load harness have to apply in order to achieve the SLA response times. Now my maths is a tad scratchy, but I knew ...

This is another blog in a similar vein to "No LoadRunner, No Problems" where I needed to write a custom test harness for MQ server. IBM kindly provide a complete Java API for getting in to the nitty gritty of MQ messages. Much can be learnt from WebSphere MQ sample ...
