This week, for a change, I’m publishing a blog entry from Marcel den Hartog, Principal Product Marketing for CA Technologies Mainframe Solutions.
Many moons ago, some smart people invented machines to do things (that were previously done manually) faster, better, and more consistently. Good examples are the car industry, the way we make (made) light bulbs, and how we produce clothes or other fabrics. Not much later, people invented machines to automate administrative tasks, so we could calculate faster and have better insights in our financials, with fewer people than ever before. Programmable typewriters are an early example, but the first simple computers did exactly that, add and subtract numbers faster and with fewer errors than an employee could (and ideally with no errors at all!).
The main reason for people inventing “machines” like this was to do things more efficiently, which in turn would make them more competitive. It was as simple as that. True, the equipment was a bit more complex, but the advantages far outweighed the problems of complexity.
This is where Information Technology was born. We soon needed people to drive these “machines”, maintain them, and program them to perform new tasks. And before we knew it, we had simplified a lot of manual tasks, invented some that we didn’t even know existed, and, probably even more important, we were seen as just another part of the business. A part that was able to help the company to run more efficiently and become more competitive.
Automation, in the most general sense, also helped our civilization to evolve faster and faster. Automating more meant we had more time to study, more time to invent even better technology that could automate even more...
However, somehow, at some point in the recent past, something went wrong. We kept implementing more technology that helped us to automate more bits and pieces, but we somehow forgot the next step of automation – automating our automation. Sounds weird? Well, look at how many manual interventions today’s IT systems need to keep them healthy. Ask your IT peers why it still takes 10 days to implement a new server (or 3 days if you do it on a virtualized server farm). Go and ask your Help Desk staff how much time it takes for a performance issue to bubble up, and get fixed again. Ask your operations staff how many of their events (across platforms) have automated actions attached to them that do stuff that could replace manual interventions...
Now, please don’t get me wrong, I know that there are many IT departments that have implemented automation in their IT environment. But in all fairness, it’s not really enough to cope with the complexity of today’s environments. There is another reason, however, for bringing this up now. In the past four years, many IT departments have implemented virtualization in some way. Some have been more successful than others, but there is one thing most people seem to agree on: the current mix of servers – Enterprise Servers like the IBM mainframe, standalone Unix, Linux, and Windows servers, and many virtualized systems running different kinds of OSs – is already hard to manage, and automation is already quite difficult. If the signs are right, we will add a lot of new stuff making it even harder to monitor, manage, and control everything we have.
With the addition of support for mobile devices, Cloud initiatives, and Big Data, we will be confronted with new and unpredictable behaviours arising from our systems. So if there were ever a time to give some extra attention to automate the things we already have, it’s now – at least then we will be more prepared for the unknowns that these new initiatives will bring us. I really think that this is also one of the ways to demonstrate to “the business” that IT really is ready to bring in the new IT services that the business requires. In the past, IT has often been accused of spending too much money to “keep the lights on”. Part of this, as we all know, is the fact that we still spend too much money and time on manual work (and interventions ) to keep these same lights on.
Now, please go back to my first paragraph and tell me if this sounds familiar. The business is now ready for new initiatives like Cloud, Big Data, and more and better support for mobile devices because it will help them to work in a more cost-effective way. IT is also ready for the next step, when we will be required to automate more of what is now running the business, to make sure that it runs as an efficient engine that needs a lot less attention, but also to free up the resources needed to run the new services that the business requires us to run...
I think we can all agree that what I just wrote makes sense. So why not go back to history once more for a final lesson?
Many Fortune 500 companies still run the majority of their mission-critical business services on a mainframe. And for good reason: it is a reliable environment, cost effective, and it is a platform that doesn’t confront managers with a lot of surprises. Some people might call this “boring”, others would say that it’s the way things are supposed to be run. Because of the nature of the mainframe (it was once the ONLY platform to run IT services on) automation has been perfected on this platform in the past decades. Some companies have tens of thousands of “rules” that kick in once unexpected things happen. Looking for proof? See how many people the average mainframe is managed with, compare that with the amount of mission-critical transactions running on that same mainframe, and everybody will agree that you need fewer people to manage a mainframe than you do to manage other environments. With mainframes, you really can have IT made simple.
People learn from the past. Experience is what has brought mankind to where it is today. But for some strange reason, we tend to think of history as something that goes 50+ years back. In IT, going back in history to learn something simply means going back 6-10 years. Talk to your mainframe peers, learn from their experience, and find how you can benefit from their automation expertise. It will not only make your current infrastructure run better, it will also help you to demonstrate to the business that you are ready for the next bulk of new and innovative IT projects – and you will save some money at the same time. And who doesn’t want to do that these days?

The Arcati Mainframe Yearbook 2013 has been published
Every year, about this time, mainframe users are excited to get their hands on the latest edition of the Arcati Mainframe Yearbook. What makes the Yearbook stand out is that it’s an excellent reference work for all IBM mainframe professionals – no matter how many years of experience they have.
What makes this annual publication so important? The answer is that it provides a one-stop shop for everything a mainframer needs to know. For example, the technical specification section includes model numbers, MIPS, and MSUs for zEnterprise processors (zEC12s, z196s and z114s). There’s also a hardware timeline, and a display of mainframe operating system evolution.
In addition, there’s the glossary of terminology section explaining what all those acronyms stand for, in a way that means you can understand them.
One section provides a media guide for IBM mainframers. This includes information on newsletters, magazines, user groups, blogs, and social networking information resources for the z/OS environment. Amongst the things it highlights are Enterprise Tech Journal, IBM Listservs, SHARE’s Five Minute Briefing on the Data Center, Facebook (fan) pages, and LinkedIn discussions. As well as user groups such as SHARE and IDUG.
The vendor directory section contains an up-to-date list of vendors, consultants, and service providers working in the z/OS environment. There’s a summary of the products they supply and contact information. As usual, there are a number of new organizations in the list this year, and, sadly, a few familiar names have ceased trading.
The mainframe strategy section contains articles by industry gurus and vendors on topics such as: Where is the COBOL in your SOA?; Lost without a trace?; and Challenging times lead to new tools for z/OS control and network management.
For many people the highlight each year is the mainframe user survey. This illustrates just what’s been happening at users’ sites. It’s a good way for mainframers to compare what they are planning to do with what other sites have done. I will be looking at some of the survey highlights in a future blog.
The other great thing about the Yearbook – as far as many of the 20,000 people who download it are concerned – is that it is completely FREE.
It can only be free because some organizations have been prepared to sponsor it or advertise in it. This year’s sponsors were: Software AG, Software Diversified Services (SDS), and William Data Systems.
To see this year’s Arcati Mainframe Yearbook, click on www.arcati.com/newyearbook13. If you don’t want to download everything at once, again this year, each section is available as a separate PDF file.
Don’t miss out on this excellent publication.

How much data is enough?
In the past, the only way of storing data was in your head. So, in less developed societies, older people were revered because their heads contained information about how to deal with problems. They remembered how the tribe or village survived last time everywhere flooded or the last major drought. They knew high spots or springs that don’t dry up.
Many societies have tried to make this information available to others by creating songs or poems that recite the lore – so that future generations will not forget the deeds of great heroes, but, more importantly, the list of tips and tricks for surviving in difficult situations.
Then came writing. There was now the ability to list the kings, so it was obvious who should be the next ruler. Or to list the goods that were to be bartered for some other set of goods. Or to record just how many sheep and goats someone owned at the end of each year. And writing in stone, which could last for many years, was later replaced by writing on papyrus, and eventually on paper. With the advent of printing, it became possible to create definitive lists of laws or stories that everyone had access to (well, provided they could read!).
And in our headlong rush through time, we get to the early computers. People could store information on them – like the milk yields of their cows and how much food the herd consumed, or how many coffees were sold in each coffee shop in a chain, or what you wanted for Christmas. And not only could you store data, you could calculate answers to questions. But it was all pretty much driven by humans for humans. And generally you knew where it was stored – even if it was on a mainframe in a different country, you could find the address of site.
But now two of those factors are changing, and changing in a very big way. Now, a lot of the data isn’t created by humans, it’s coming from devices. Let me expand on that. Every time you use your credit card, information about your purchases and where you purchased them is very likely stored somewhere, so the retailer can target adverts at you, and so they have a better idea of what types of product sell well in different parts of the country. Requiring even less human intervention is all the footage that gets stored from security cameras. No humans are involved in the recording and storage. And there are many other examples of devices that just store information. As time goes on, and more-and-more information is stored, there’s going to be a requirement for more-and-more storage. I’m sure someone somewhere has worked out the numbers, but if 500GB of storage occupies half a square foot, and the amount of data stored doubles every year, then in 20 years time, the whole planet will be covered in storage devices to the depth of 18 inches!!
But where is your data? Originally it was on your hard drive or on DASD in your organization’s buildings. But nowadays, I have most of my customer-facing files on Google Drive, and, so long as I’m in a wifi area, I use the CloudOn app on my tablet to show customers PowerPoint presentations as well as Word documents and Excel spreadsheets. I also use Dropbox for sharing files with friends. The point I’m making is that I have no idea where those files are physically stored. And, for business files, that brings a huge security issue. For example, European organizations are pretty much prevented from using US-based, or indeterminate location, because they’re outside the EU.
It seems at this rate that there will always be more data to store (somewhere) – and hopefully there will always be enough storage, without covering the whole planet. But will there be any more knowledge in the world?

2012 at iTech-Ed Ltd
As it’s the start of the New Year, I thought I’d review events of 2012 through the lens of events at iTech-Ed Ltd.
In January, The Arcati Mainframe Yearbook 2012 was published. It had around 20,000 downloads during the course of the year, and I’m Editorial Director for this highly-respected annual source of mainframe information. My blog, “Gazing into the IT Crystal Ball...”, was published on the Destination z Web site. And the Virtual CICS user group meeting on 17 January had a presentation from IBM Hursley’s Andrew Smithson entitled, “CICS Transaction Gateway V8.1”.
In February, my blog “Staying in Touch With the Mainframe Community” was published on the Destination z Web site, and an earlier blog was quoted from on the Dancing Dinosaur site. The Virtual IMS user group had a presentations from Neil Price, a senior DBA and systems programmer with TNT Express ICS on 7 February. His talk was entitled, “Memoirs of a HALDBA”.
My article entitled: “The z114: Delivering Game-Changing Opportunities” was published in the March/April issue of z/Journal. My blog “Saving Money With Mainframes” can be found on the Destination z Web site. And of the 6 March, the Virtual CICS user group meeting had a presentation from Fundi Software’s Jim Martin entitled, “Analyzing CICS function shipping applications using Transaction Analysis Workbench”.
3 April saw a presentation to the Virtual IMS user group by Fundi Software’s James Martin, entitled, “Using IMS Performance Solution Pack for z/OS to analyze IMS performance problems”. And my blog “The Sincerest Form of Flattery” was published on the Destination z Web site.
In May, my blog “The Mainframe’s Potential to Get Social” was published on the Destination z Web site. And on 8 May, at the Virtual CICS user group meeting, Stephen Mitchell, Managing Director of Matter of Fact Software Limited, gave a presentation entitled, “Utilizing the Dojo Toolkit for Web browser-driven applications from CICS”.
The 12 June saw a presentation by GT Software’s Dusty Rivers to the Virtual IMS user group entitled, “Modernizing IMS”. And the Destination z Web site published my blog “Atomic Weapons and the Dawn of the Computer Age”.
On 10 July, Ezriel Gross, CEO of Circle Software Inc, gave a presentation to the Virtual CICS user group entitled, “CICS introduction to Web services for the system programmer”. Also in July, my blog “IBM and Augmented Reality” was published on the Destination z Web site.
The Virtual IMS user group enjoyed a presentation by SQData’s CEO, Scott Quillicy, on 7 August entitled, “Best practices: IMS to relational data movement”. My blog “BYOD and Network Security” was published on the Destination z Web site in August.
In September, my blog “IMS: There’s Still Life in the Old Dog!” appeared on the Destination z Web site. Also in September, the Virtual CICS user group enjoyed a presentation entitled, “Success paths for integrating CICS with new technologies” from Don Spoerke, Principle Solutions Engineer with GT Software.
October saw my blog “What’s New With CICS?” published here on the Destination z Web site. In the same month, IBM’s “Think BIG” Information On Demand conference site published “IOD from Afar” and “IOD News” on their official IOD blog site.
In November, Colin Pearce gave a very enjoyable and detailed presentation to the Virtual CICS user group about “CICS security”. The IBM ‘Proud to be part of z’ poster came out that month. Look out for the person in the bottom row, third from the left! And the Destination z Web site published my blog “New Poster Captures the Mainframer Mosiac”.
On 4 December, the Virtual IMS user group had a presentation by BMC’s Bill Chapin about “Nearing 24x7 availability with structure changes too!” Also in December, Trevor’s blog “Whatever Happened to the Network Guy?” was published on the Destination z Web site.
Also last year, I was made a 2012 IBM Champion – that’s four years in a row I’ve been an IBM Champion. I continued to blog at mainframeupdate.blogspot.com and it.toolbox.com/blogs/mainframe-world/. And I continued to tweet at twitter.com/t_eddolls, twitter.com/virtualims, and twitter.com/virtualcics. And on Facebook you can find me at fb.com/itech-ed, fb.com/VirtualIMS, and fb.com/VirtualCICS. And I have groups on LinkedIn for Virtual IMS (www.linkedin.com/groups?gid=379256) and Virtual CICS (www.linkedin.com/groups?gid=3847862) – come on LinkedIn, do short names! And I’m on Google plus (if you like, you can find me at gplus.to/teddolls).
And don’t forget, the Arcati Mainframe Yearbook 2013, will be published very shortly. And look out for this year’s meetings of the Virtual IMS and Virtual CICS user groups.

Shopping
It seems that as you get closer to Christmas and the New Year, everything starts to run down like an old clockwork toy. Meetings scheduled for 2013 seem ages away, even though some are at the beginning of January. And phone calls so often find the person you’re ringing out of the office – whether that’s doing a bit of family shopping or attending the numerous party and lunch invitations. And as for e-mail, people seem to leave their out-of-office message on permanently!
To be honest, I’ve been closeted away trying to get the bulk of the Arcati Mainframe Yearbook 2013 sorted out. I’ve been calculating the numbers for the user survey – and very interesting they are too. But I’ll talk more about them next year. I’ve been busy placing articles and organizing entries for vendors and consultants in the appropriate sections. So, no partying for me this week. BTW if you wanted to be included in the Yearbook, e-mail me immediately here.
I’ve also been working away at a speaker programme for the Virtual IMS user group and the Virtual CICS user group. The first meeting is on 15 January when IBM speakers will talk about the CICS V5.1 - Portfolio Update. But, as I say, it’s in January and seems an age away! If you or your company are interested presenting to either group during the year, then let me know here.
It seems that no matter whether you’re Christian, atheist, agnostic, or a person of any other faith, everyone likes a present from Father Christmas (Santa). So what do you buy the IT guy who seems to have pretty much everything? Somehow socks just don’t seem to show any real thought. Alcohol is usually well received, as are things from the more expensive end of the catalogue. But I’ve got a couple of other suggestions.
I’ve been playing with a magic magnetic balls cube. It’s 216 small magnetic balls that you can shape into all sorts of 3D things. And then you can scrunch them all up and start again. But the really hard part, is getting them back into the cube shape. Remember magnets repel as well as attract. So you can play with them for ages.
I’ve also been working with a variety of organizations on social media – getting Facebook fan pages set up, starting using Twitter, and putting videos on Youtube. And I found the like and dislike Facebook-like stamps can be quite fun. Whatever happened to the paperless office? As documents pass across my desk, I can (mainly for my own amusement) stamp them with a Like or Dislike (thumbs up or thumbs down). You’ll probably enjoy doing much the same!
There are lots more ideas at www.paramountzone.com, such as touch-screen gloves, iHat music hat, USB mug warmer, flying monkeys, a one million pound bank note, alcohol breath tester keyring, tap shower radio, and light changing glow ball.
And, for the mainframer in your life, you could try to get hold of a “Proud to be part of z” poster. You can see a copy here.
So, whatever you’re doing over the next couple of weeks, have a great time. See you next year.

Putting it all together
I was chatting to Tony Amies, product architect at William Data Systems, about the best way to get information from a mainframe (and about what’s happening on that mainframe) out to someone who has access to a browser. He had a number of nifty techniques that I’d like to share with you.
Assuming you want to get the information from your mainframe to a browser, your first really big decision is do you want to go with two-tier architecture, or do you want to go with three-tier architecture? Tony’s advice was that two-tier was enough.
That leads to the second really important decision to be made, which is where should the processing take place? You’ve got to look at what needs to be done and then make a choice about which platform does that work best on. So, for example, and perhaps quite obviously, if you want to monitor what’s going on with IP, FTP, or EE (Enterprise Extender) on your mainframe, you want that processing to take place on the mainframe. That all seems fairly easy!
But what do you want to do with your results from those different monitors (and indeed any other monitoring software you have running)? Do you want to look like mission control and have a 3270 screen for each monitor that’s running. Now, I remember how impressed visitors used to be when they saw something like that, but if my plan is to get the information to laptop or tablet device running a browser, then I probably need to consolidate the different feeds first. And, again, I want to do that on the mainframe, in the same LPAR (Logical PARtition) that the monitors are running in. It makes sense because much less work has to be done than if I choose to send that data somewhere else for processing.
If you’re familiar with WDS products, you know about their ZEN monitor for their other products. They’re written in Assemble and C and they use a little DLL inside each product that talks to a DLL in ZEN and you can see a nice display of what’s going on – on everything. As a side note, using the DLLs allows the products to talk to each other, so that if the IP monitor spots something, then the IP trace tool can be used to investigate further.
So, using the two-tier architecture, ZEN is logically split into two parts. One part is mainframe friendly and one part is Web friendly. Associated with the Web-friendly part of ZEN are the necessary JavaScript libraries and JQuery libraries, and the usual HTML bits. If you’ve not come across JQuery before, it’s like a lot of clever JavaScript that’s been already written that you can use to make your Web site look very modern. Lots of sites use the jQuery lightBox plugin to show photos.
There’s always a problem with busy Web pages in that lots of information has to come from the server to the browser, resulting in lots of network traffic – and if you’re monitoring your mainframe’s network from a browser there can be even more. So the first technique they’ve used is AJAX (Asynchronous JavaScript and XML), which means that only the parts of the Web page that have changed are sent, the rest of the page stays the same. They also use JSON (JavaScript Object Notation) as a lightweight data-interchange format.
But there’s always an issue with any User Interface and that’s how to separate the actual user interface itself from the business logic behind it. In technical terms, these are known as the view model and the data model. To make this work as effectively as possible, they’re using MVVM (Model View ViewModel), which is a framework or architectural pattern coming originally from Microsoft, but now extended to include JavaScript MVVM. You can get a clearer idea of the sorts of things they’ve done – and perhaps the sorts of things you could do from knockoutjs.com. The site describes itself as “simplifying dynamic javaScript UIs by applying the Model-View-ViewModel (MVVM) pattern”. The WDS developers also familiarized themselves with prototypejs.org, a site describing itself as “a foundation for ambitious web user interfaces”. They go on to say: “Prototype takes the complexity out of client-side web programming”.
For WDS, basically an object is requested from the browser by the user. This goes up to ZEN. Using JSON, a data object comes down and binds with the layout defined in the MVVM skeleton. As a user, you see dynamically updated information in your browser. If one new value affects other values, those other values are automatically update appropriately.
I’m not endorsing WDS’s products, I’m saying that they have very effectively made use of the very latest technology at the browser end to make their product work very efficiently. I’m suggesting that the two-tier architecture with really clever stuff on the browser side is definitely worth taking a look at.
Assuming you want to get the information from your mainframe to a browser, your first really big decision is do you want to go with two-tier architecture, or do you want to go with three-tier architecture? Tony’s advice was that two-tier was enough.
That leads to the second really important decision to be made, which is where should the processing take place? You’ve got to look at what needs to be done and then make a choice about which platform does that work best on. So, for example, and perhaps quite obviously, if you want to monitor what’s going on with IP, FTP, or EE (Enterprise Extender) on your mainframe, you want that processing to take place on the mainframe. That all seems fairly easy!

Computer futures
It’s December. It’s the time of the year when people are either reviewing what kind of a year it has been for them or predicting the future. I thought that this week I’d look forward to next year.
The big news for mainframe users is, of course, the price hike promised by IBM. If you go to http://www-01.ibm.com/common/ssi/ShowDoc.wss?docURL=/common/ssi/rep_ca/9/897/ENUS312-129/index.html&lang=en&request_locale=en you can see that from 1 July, the price of Flat Workload License Charges (FWLC) will increase.
According to Timothy Prickett Morgan writing for The Register: “IBM has a wide variety of monthly software pricing schemes for its System z mainframes, but the FLMC scheme is interesting in that it applies to all machines regardless of size or vintage equally and as you increase the capacity of the mainframe, the software fees stay flat.
“The bad thing about the FWLC scheme is that it does not have what IBM calls sub-capacity pricing, where customers use virtualization to isolate capacity on a particular mainframe and then only get charged for that software based on the MSUs consumed in that logical partition.” MSUs are Metered Service Units. It looks like the average price rise will be around the 10 percent level.
We probably won’t be making use of Application Performance Management Software as a Service (perhaps more easily written as APM SaaS). A survey conducted by IDG Research Services online among members of the CIO Forum on LinkedIn during August found that 61 percent of organizations have no plans to implement APM SaaS. But around a quarter (24 percent) already use APM SaaS in some capacity, with a mere 4 percent are using an APM SaaS vendor to monitor all their critical applications.
A CA Technologies survey found that 80 percent of Australian organizations are expected to face a shortage of mainframe skills in the future, with 57 percent already experiencing difficulties. The skills shortage issue is one that IBM, CA, and other companies are addressing with graduate and undergraduate programmes of study on mainframes.
The good news from the survey is that the mainframe is also playing an increasingly strategic role in managing the evolving needs of the enterprise. Again this comes as a surprise to no-one who knows about mainframes. With the growth in use of Linux on the mainframe, organizations can save lots of their budget. And the new hybrid models allow sites to get the best of all worlds.
The survey also found that 36 percent of respondents anticipate an increase in hardware spending in the next 12 to 18 months. Good news for hardware vendors. 44 percent of respondents are planning to increase their spending on mainframe-related services.
And while our focus is on mainframes, we all use laptops, tablets, and smartphones, so it’s interesting to see that Steven Sinofsky has left Microsoft. Who’s he, you say? Well, he was one of the driving forces behind Windows 8. Similarly, Scott Forstall has left Apple. Both were working to get laptops, tablets, and smartphones to use much the same interface and appear to the user to all have the same look-and-feel. Perhaps that touchscreen-style way of working will make its way to the interface to mainframe applications? Or perhaps in many ways it has in so far as remote access to mainframes can be achieved over the Internet from a browser on any platform.
I definitely predict more things will decide they are ‘cloud’ things. Mainframe users have been saying all along that they used to sit at a terminal and not worry where the application software lived, or where the data was stored – they just knew it was ‘out there’ and got on with their work. I’m sure this ‘cavalier’ attitude is one most users would like to be able to embrace. We’ve all had the problem with a file being on our office computer when we need it in the evening or weekend, or being on our home computer on Monday morning when we’re in the office. IT departments can sweat the security issues, but users will love the idea of it all (data and apps) being out there and available from anywhere.
Finally, if you’re a vendor, don’t forget to update your information in the Arcati Mainframe Yearbook 2013 – you can do it here. And if you’re a mainframe user, then help us by completing the user survey here.
