I wanted to show how easy it was to expose a CICS file as a ATOM feed and then consume it within a AJAX web page. This would allow me to respond to a users request via a web page without having to reload the entire page. Making the UI cleaner, more efficient and well 'sexier'!
The demo took very little time to create. I took the CICS File A sample and quickly created the necessary CICS resources to allow CICS to expose it as a ATOM feed. A quick test in the browser showed me that all was working well and that I now had a REST style interface for my file. CICS still handled the file and ensured that authentication was properly handled. My existing demos that use that file didn't have to change, BUT I had managed to levarge this file to new consumers. Ah my next point - writing that AJAX web page.
In a real company this would mean that we would be able to create web 2.0 components that connected directly to CICS. This would provide a up to date interface that customers expect. You wouldn't even think that CICS was involved.

As I am an IBMr I am really proud to have been asked to speak at this conference and am really looking forward to meeting our customers and showing them some of the cool functions of our software.
Over the week I will be presenting on:
Old Stager Vs Greenhorn - this wasn't my title but during the session I will be comparing application development environments on the mainframe and on other related platforms. I will be showing where modern application development paradigms fit within the mainframe and where they don't. As a point of fact I will be showing Rational Application Developer for System z. This tool forms part of the IBM Software development platform and allows mainframe based application developers to write applications that will allow them to make the most of the mainframe.
Securing CICS Web services. Did you know that CICS can be a first class participant in SOA and webservices? well it can and it does the job with usual CICS QoS. One question that we are often asked is how can we strategically propagate a users credentials with the webservice to ensure that the CICS application uses the correct ID to access confidential data. This session is going to get very technical. However by the end you will understand what options are available to you and which may be the right option for your enterprise.
Simple Sample web 2.0 example. Web 2.0 is it just a buzzword or does it really exist? was there a web 1.0? were there bug fixes between version 1 and 2? If the answer is yes to any of the above questions what does that mean to CICS. Does CICS need to play in web 2.0 and why would it be useful. In this session I will be picking through the buzzwords to understand what CICS can do to allow Web 2.0 applications to access your data in a way that reduces risk to your existing workload and allow you to create situational applications quickly.
Why I am speaking about these topics. Surely it would be better to get a development lead to talk instead of the tester. However as a system tester it is my job to understand the value a customer would receive from the new function. Thus I have experience in applying the technologies to other parts of the enterprise.
Also Please remember I am not a salesperson so each of my sessions will be from my PoV giving you real scenarios that I have created.
If you are planning to come to impact and would like to have a more indepth chat about any of the technologies then please:
Catch me at the end of a session
Speak to any IMPACT organiser who can contact me for you

Look forward to seeing you at Impact

A single CICS region can only connect to a single queue manager or a single queue sharing group. Thus we can always assume that the queue manager that you want to connect to is the same one that CICS is connected to.
However since the java MQ api requires you to specify a queue manager name in the constructor, as a developer this can make you think "err where do I get the queue manager name from". The JCICS api doesn't contain a way of getting to it.
The easiest solution is to construct a queuemanager object by passing an empty (not null) string into the constructor. When you later attempt to get or put a message to that queue, CICS will ensure that we use the correct queue manager.
That's what I learnt today and it made writing my CICS java MQ application a lot easier

Now the key to losing weight is to simply use more energy than you eat, simple surely?
Working out the energy in value is easy, just use food wrappers and the information is there. However calculating the energy used is a lot harder. Gym equipment can help but isn't completly accurate, also what about energy burned when not connected to a treadmill? Just writing a blog - that must use energy!
So I wish that the human body had a data access port (USB would be my preference) to allow me to download how much energy I have used and such like. This would also make a docotrs job a lot easier as they would never need to run any diagnostic tests, just connect you to their laptop and get a complete view of your health.
We could even write software to interpret the data, similar to the jvm health checker. I think this could be a really good idea.
Alas since we don't have such a wonderful port I guess that I will just have to go and get weighed again tomorrow and hope that I am a little thinner and lighter than I was a week ago
