Perfharness is a flexible and modular Java package for performance testing of HTTP, JMS, MQ and other transport scenarios. It provides a complete set of transport functionality, as well as many other features such as throttled operation (a fixed rate and/or number of messages), multiple destinations, live performance reporting, JNDI. It is one of the many tools used by performance teams for IBM MQ and IBM Integration Bus in order to conduct tests ranging from a single client to more than 10,000 clients. Customers also use the tool to test their own systems and validate they perform accordingly.

The top level folders in the repository are Eclipse projects.

• Download the repository zip file and extract into a temporary directory.
• Import the projects using the Import Wizard selecting "Existing Projects into Workspace".
• Select the 5 projects and make sure "Copy projects to workspace" is ticked when importing.

This should result in you having a workspace with the following projects:

Building Perfharness in Eclipse requires some extra dependancies importing to the workspace. Depending on the modules you would like to build please import the following files into the PerfHarnessPrereqs project, these files are either available on the web from Apache or from the respective product installations. JMSPerfharness requires WebSphere MQ8, MQJavaPerfHarness requires WebSphere MQ7 (or above) and the Perfharness and HTTPPerfharness modules have no prereqs

See the MQ knowledge center for details of the IBM Classes for Java. E.g. for MQ V9: Developing JMS and Java applications

Additional Pre-reqs for AMQP Channel Module

• The Java AMQP Client required by this module can be download from https://developer.ibm.com/messaging/ibm-mq-light-downloads and selecting "Download from Maven Central". Refer to the AMQP Client READ.md as further pre-reqs jars are required.

• The allclient.jar is required from the a MQ V9.0 installation.

• Copy all of the pre-req jars into /lib of the AMQPPerfharness.

Once you have imported the pre-reqs you are ready to run within Eclipse or compile the jar for using on other machines. If you would like to run perfharness create a new Run Configuration for a Java application. Generally we would recommend running from Eclipse for functional and setup testing but for real performance testing using the jar from the command-line on a server.

Select "JMSPerfHarnessMain" as the Project and "JMSPerfHarness" as the Main Class as shown below

On the "Arguments Tab" insert the appropriate set of program arguments such as (MQ Receiver Example):

Select the Classpath tab, highlight the "User Entries" section and click the Add button. Add all of the PerfHarness projects to the classpath. This should result in a configuration such as this:

Click "Run"

There are 4 scripts which can be used to compile Perfharness.jar depending on whether you want all the capability or a specific one. The 4 scripts are:

• Perfharness/build_all.xml - Used for building the whole package.
• Perfharness/build_HTTP&TCPIP.xml - Used for building only the http & tcpip modules.
• Perfharness/build_JMS.xml - Used for building the JMSMQ module.
• Perfharness/build_MQ.xml - Used for building the MQ module.

To compile perfharness.jar right click the the appropriate .xml file and select "Run As" then "1 Ant Build".

This should launch the build process which will produce the jar file perfharness.jar
