WebSphere Message Broker Part time Development

If you are looking for WebSphere Message Broker V6/V7 development for your company please contact me. I am an certified WebSphere Message Broker Developer.

WebSphere Message Broker Hypervisor Edition

Websphere Message Broker JMS flow

Below is a basic Websphere Message Broker JMS flow using Websphere MQ JMS.

Setup of Websphere MQ for JMS flow:

Step 1: Create JMS Initial Context

Step 2: Create Connection Factory

Specify the WMB Queue Manager as the JMS Queue Manager

Easy way to JMS Queues it to create a Lcoal Queue and right clicking on it and selecting ‘Create JMS Queue’

Step 3: Specify a JMS Destination

Step 4: Deploy and Test the flow

JMS flow is great for integrating with Websphere Application Server where an application executes code and put the result on a JMS queue, the JMS picks the information up and processes by doing validation, transformation and mediation.

Important to note is that Websphere Message Broker only supports Websphere JMS and no other JMS provider.

Websphere Transformation Error Handling in Websphere Message Broker

How to catch Websphere Transformation Extender Error in Websphere Message Broker:

I have created a flow that will validate a message (WTX Validate) and also catch any error:

The Transformation Errors can be put on a Queue to be consumed by an Monitoring tool, Exported to a file for debugging.

Install Websphere Message Broker V7 on AIX

Install Websphere Message Broker V7 on AIX:

FTP all the relevant files to your AIX machine, this software includes:

1. Websphere MQ for AIX

2. Websphere Message Broker for AIX

Websphere MQ must first be installed before attempting to install WMB as WMB requires lib files from MQ.

Step 1: Open a command window and extract Websphere MQ, next run: sudo smitty

Step 2: Define the file path location of MQ for AIX: /installs/WebsphereMQ

Step 3: Define the “ALL” software needs to be installed and change the license agreement to “YES”

Step 4: Successful install of Websphere MQ

Install Webphere Message Broker:

Step 1: Open command line and navigate to the messagebroker1_runtime folder

Step 2: Run the following commnad: sudo ./setupaix -console

Step 3: Go through the Broker Wizard and confirm that Broker was installed successfully.

After installation navigate to: /opt/mqsi/7.0/bin

Run the following command: sudo ./ mqsicreatebroker WBRK_DEV -q WMQ_DEV

Confirm that broker has been created successfully.

Confirm that you MQ QueueManager listerner was created and started, if it was not started use the following command:

runmqlsr -t tcp -p 1414 -m WMQ_DEV

See link for more information:

http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp?topic=/com.ibm.mq.csqzah.doc/qc10410_.htm
