Also you can install it through JMeter Plugins, search “IBM MQ Support”.

Usage

After installing mqmeter, you can choose two kind of Java Sampler, these are:

MQClientSampler

Use it to put and get message (optional) on MQ queue. On JMeter add a Java Request Sampler and select the MQClientSampler class name. The following parameter are necessary.

• mq_manager: MQ Manager name. You can find it through IBM WebSphere MQ Explore or console.
• mq_queue_put: MQ Queue name to put message. Could be Local or Remote queue.
• mq_queue_get: MQ Queue name to get message. Could be Local or Remote queue. Leave it empty if you don’t want get response message.
• mq_correlate_msg: Correlate the response message with request message to get the right message from the queue. Put ‘messageId’ or ‘correlationId’ values. Leave it empty if you don’t want get response message.
• mq_wait_interval: Set wait interval that the get message call waits for a suitable message to arrive. Similar to time-out to get response message on queue.
• mq_hostname: Host name or ip address where MQ Server is running.
• mq_port: Port number of the MQ Server listener.
• mq_channel: The Server channel name on MQ Server.
• mq_user_id: The userID to connect to MQ server channel. Leave it empty if you don’t need user id to connect to MQ.
• mq_user_password: The user password to connect to MQ server channel. Leave it empty if you don’t need user id and password to connect to MQ.
• mq_use_mqcsp_authentication: The connection authentication used. Set false for Compatibility mode, or true for MQCSP authentication.
• mq_encoding_message: Character encoding standard for your message: For EBCDIC put Cp1047. ASCII just put ASCII.
• mq_message: The content of the message that you want.

MQPublishSampler

• mq_topic: MQ topic name to publish message.
• mq_hostname: Host name or ip address where MQ Server is running.
• mq_port: Port number of the MQ Server listener.
• mq_channel: The Server channel name on MQ Server.
• mq_user_id: The userID to connect to MQ server channel. Leave it empty if you don’t need user id to connect to MQ.
• mq_user_password: The user password to connect to MQ server channel. Leave it empty if you don’t need user id and password to connect to MQ.

• mq_message: The content of the message that you want.

Troubleshooting

When use the MQPublishSampler Java Sampler is possible that you get the below exception:

java.lang.NoSuchMethodError: com.ibm.mq.MQQueueManager.accessTopic(Ljava/lang/String;Ljava/lang/String;II)Lcom/ibm/mq/MQTopic;

It is throw because there is com.ibm.mq* jar file that is upload by JMeter and it does not have the methods related with topic or other MQ objects. It jar file isn’t related with mqmeter plugin but JMeter calls it first.

Checking JMeter lib and ext folders to remove com.ibm.mq* jar files that do not have methods or mq topic objects.
