BYOD

There was a time when you had to go into the office to use the mainframe. Then, with SOA, we allowed people to access from browsers running on any devices anywhere. Nowadays, people are wanting additional flexibility and demanding that they can work using their preferred computing device, rather than one allocated to them by IT.
 
You can understand why. I know of a number of sites that still roll out XP laptops to staff because they didn’t like Vista. They have older software applications that stop them moving to Windows 7 and IE9. You can understand why their staff would be frustrated in that situation. People who own super whizzy iPads and Samsung Tabs, or top of the range smartphones that can do pretty much anything, find that going to the office is like going back in time – and they don’t want it. They want to use their own devices, which they’re familiar with and can carryout their own simple IT support on, to access their work applications. Hence the growth of BYOD – Bring Your Own Device.
 
There’s also a growing population of Mac users that find they don’t get any IT support from the usual IT channels. For them, a Google search will usually identify the cause of a problem and a solution, and so they can get on with their work. If you are a Mac user, there's plenty of Mac to MVS info at http://planetmvs.com/mvsintosh/index.html.
 
Nowadays, users at Windows-based sites can easily connect to things like a Citrix receiver and access a virtual work desktop on their hardware device of choice.
 
In a further complication, Canonical is developing an Ubuntu release that can run alongside Android on high-end dual-core smartphones. When the smartphone is docked, the user gets a full desktop experience. The Linux operating system shares the Android kernel, enabling the safe sharing of resources and data by going through the same kernel access layers. This offers all sorts of advantages. Users have a phone that works, plus, once docked, have a working computing environment. It’ll be interesting to see whether we see a lot more of Ubuntu for Android. Can you imagine being able to do that with Windows?
 
VMware’s Horizon mobile application (announced last summer) lets workers use personal mobile devices for work, while letting IT retain security and control over work-related apps on those phones. In effect a user has the handset they want and runs their work phone virtualized on the same hardware. The user gets the handset they want, and IT get the security they need.

And you can access the mainframe with your iPad. For example, you can have 3270 emulation – MochaSoft provide TN3270 from the Appstore. Rational HATS and WebSphere Application Server (WAS) can help make CICS access from an iPhone possible. Lotus Notes Traveler accounts allow users to access Notes from iPhones or iPads.

There’s a free Quick Reference for IBM System z mobile app available for Android, BlackBerry, and iPhone, which (IBM claims) provides quick and easy access to the latest System z product information, success stories, social networks, and z experts. You can get it from www-03.ibm.com/systems/z/resources/mobileapp/index.html.
 
Many software vendors are making use of the browser on tablet devices and smartphones to provide access to mainframe data – I’ve written about William Data Systems software in previous blogs, but they are a good example of a vendor embracing new technology to access mainframe performance info.
 
My opinion is that tablet devices are not quite there yet, and, like early laptops, will be a million times more useful and usable in a couple of years time. But plenty of people have them, and it makes sense for those people to access the applications they want on corporate systems, whether that’s a copy of Excel or a CICS transaction.
 
Watch out for more people demanding to bring their own device!

How to create an e-book

For those of you who’ve been living on Mars, an e-book is a book that you can read using an e-reader, such as a Kindle or using the Kindle app on your smartphone or tablet. And the great thing is that anyone can publish an e-book. You don’t need to find a publisher, you just need a computer. On the other hand, the really bad thing about it is that anyone can publish a book, no matter how little merit it my have!

Now, obviously, there must be technical standards, so that the e-book you create can be read on a standard device. But like everything in IT, there are more than enough standards. Amazon’s Kindle uses a version of mobi and calls it Kindle Format 8 (KF8). Apple has an iBook standard called EPUB for books available from its iTunes store. Barnes & Noble have their Nook standard. And there’s Kobo, Sony Reader, iRex Digital Reader, the iRiver Story, and probably lots of others - including simple PDFs. The majority of e-book formats are based on some kind of HTML (like a Web page).
 
So, how do you create an e-book? Step 1 is to write something! E-books generally work best with text rather than text and pictures. And it seems Word is fine as the source of the text. Once you’ve done that, you need to create a nice cover, a contents list, and all the other things that you find in the front of a book. It seems to work better if you insert a page break at the end of each partial page or blank page.
 
If you want to publish for the Kindle, Amazon has KindleGen software available. I must admit, I couldn’t get it to work on my laptop. I put the files in the right place, ran it on a command line, etc. Kindle Previewer software lets you see how the layout of the book will appear on a Kindle.
 
If you have InDesign 5 or above, you can export to EPUB (for iTunes) and there is also a Kindle plug-in available.
 
I used Mobipocket from www.mobipocket.com/en/DownloadSoft/default.asp?Language=EN to convert my file. It didn’t like .docx, but was fine with .doc. However, I did lose lots of styling when I converted, so the document had to be reworked. As I said above, it’s not too clever with pictures and text boxes in a document. And that’s a problem with e-books at the moment. It’s important to keep your document as simple as possible. One other thing, the publisher edition of mobipocket protects the distribution of copyrighted content and includes Adobe PDF, Microsoft Word, and text file import wizards.
 
There’s also a piece of software called Calibre, which is available from http://calibre-ebook.com/download, that can be used to convert from one e-book format to another.
 
There are online services, like Lulu (www.lulu.com/uk/publish/ebooks/?cid=nav_ebks) that can help you publish your e-book. You upload your file, then create a cover, describe your book, pick a price, and promote your book. This gives you a route to Apple’s iBookstore, as well as selling it on Lulu’s Marketplace. In terms of royalties, Apple takes 30 percent, and Lulu takes 20 percent of the remainder.
 
If you want to publish through Barnes & Noble you can use the online service PubIt! (http://pubit.barnesandnoble.com/pubit_app/bn?t=pi_reg_home). Create an account then upload your e-book and cover art. Then PubIt! converts the digital files for viewing on Nook devices. And then you can sell it. Royalty rates range from 40 percent (for any book priced under $2.98 or over $10) to 65 percent (for any book priced between $2.99 and $9.99).
 
If you self publish to the Kindle, you earn the highest royalty rate if your book costs between $2.99 to $9.99 range. You get 70% of the price.
 
Using iTunes Connect gets your EPUB format book on the iBookstore shelves. There is an approval process, and you’ll need an iTunes account.
 
For $19.99 (and part of your royalty) you can use BookBrewer (http://bookbrewer.com/home), which lets you upload your cover, enter a description of your book, and copy and paste chapters. The e-book can then be sold through Amazon or Barnes & Noble.

Where am I in my investigation into e-books? I’ve created a book in Word that’s full of pictures with wrap-around text and text boxes with coloured backgrounds and shadows. It doesn’t convert very well. On the other hand, I have exported it as PDF and copied it onto my Android tablet into the Kindle app folder, and I can read my book using the Kindle app. (Older versions of the app don’t read PDFs.) My next task is to see whether I can ‘play’ with the HTML and create web pages that look more like my original Word pages and then go through the process again to get a good looking mobi file. At the moment, my PDF book doesn’t show up with the correct cover in the Kindle app.

If anyone’s got any suggestions, I’ll be interested to hear them.

Linux divisions

Linus Torvalds released Linux on 5 October 1991, and by 1998 IBM was experimenting with it. In 2000 it was properly available on mainframes – along with the specialty processor IFL (Integrated Facility for Linux). The rest, as they say, is history.

As well as mainframes, Linux, of course, runs on desktops and servers. The Mac OS is based on Unix, but Android – found on millions of smartphones and tablets – is based on Linux.

So what divisions am I talking about? The division between big iron and little? Well not really. In fact, interestingly, the people at William Data Systems have come out with a way of monitoring Linux whether it’s on a mainframe or server somewhere else in the world. As long as it has an IP address, they have a way of monitoring it (using z/OS as the hub).

No, the first division I want to look at is the division between the USA (or North America, I should say) and Europe. The recent Arcati Mainframe Yearbook user survey (still freely available at www.arcati.com/newyearbook12) came up with some interesting results. The survey found that  70% of European sites surveyed didn't have Linux, whereas only 28% of North American sites in the surveyed didn’t. That’s a huge difference. And if you were IBM, you might well be wondering why Linux isn’t selling into Europe so well as North America.

Let’s speculate. Is it that North America is well ahead of the curve in terms of take up of mainframe Linux? Is it that mainframe Linux is priced differently either side of the pond so it encourages the take up in the USA but not Europe? Or could it be that IFLs are marked up or down depending on whether the customer is EMEA-based or not? Are IFLs being bundled in with upgrades or not depending on where in the world you’re based? I have recently had some nudges and winks over prices, and it could well be that European mainframe users are being charged double what their US-based counterpart might expect to pay. I’d be interested to hear what figure people, who’ve recently negotiated with IBM, have haggled them down to. You might also wonder whether now is a good time to buy shares in SuSE, who have about an 80% share of the mainframe Linux market. Will we see it suddenly explode in Europe? Or not?

The other division that’s recently cropped up with Linux is how users navigate. I guess we’re all pretty much familiar with using drop-down menus to access what we want – and we can probably use them to find our way around familiar applications without even thinking about it. Even very young childen take to that way of navigating like it was second nature. But just recently we’ve seen the introduction of Heads Up Displays (HUDs) for Ubuntu’s Linux.

What you get is a sort of semi-transparent area at the top of the screen, which acts in some ways like the ribbon with Office. HUD provides a search style interface that uses a Vocabulary UI (VUI). Users start to type or say a command, and the HUD starts a smart look-ahead search through the application and system (indicator) menus. By combining fuzzy matching with a learning function, the HUD begins to ‘recognize’ the actions of each individual user.

If you want to give it a go, HUD will be available in Ubuntu 12.04 towards the end of April.

Now I’m guessing that, like Microsoft’s ribbon, and Marmite, users will either love it or hate it. The idea that it will use voice indicates to me that we’re back to the original Star Trek computer idea – a computer that you can talk to. This was an idea that went away for a while because, to be honest, voice reconition software just wasn’t up to the job. But now we’ve had Siri on iPhones for a while, and people are coming back to the idea that talking to a computer isn’t such a silly idea after all.

I’ve only spoken to one person who’s used the HUD and he was singing its praises. But he is very familiar with Linux and the Ubuntu distro, so maybe he had a clearer idea of what to ask the HUD to do for him – in terms of getting any work done – than, for example, I might have.

Perhaps one day we’ll see a HUD on mainframe Linux. And perhaps we’ll see more mainframe Linux sites in Europe, Middle East, and Africa. Or will the divisions continue?

Move over Google Docs, IBM’s back in the game!

Over the years, Microsoft has controlled the Office market – with Word and Excel being used everyday by millions of people. Even schools are teaching children to copy and paste etc using the familiar Microsoft products that they most likely also use at home.

People may fondly remember WordPerfect or VisiCalc, or may have tried OpenOffice and other alternatives to Microsoft, but for most organizations, the de facto standard has been MS Office.

And then, as the world became aware of cloud computing, those freethinkers at Google gave us GoogleDocs – an online equivalent for the basic Office functions. And the big advantage was that you could access your files from whichever computer you were on (provided you had Internet connectivity). There was no excuse about bringing the wrong memory stick and not having a copy of the document. I use the GoogleDoc plug-in to Office so that my files are stored in the cloud in case I need something at a client’s site.

Of course, Microsoft also has a cloud-based version of its Office suite called Microsoft Office 365.

But now IBM has thrown its hat in the ring. It has announced the beta of IBM Docs, which is tied into its SmartCloud for Social Business Suite. So how does IBM hit the ground running with its own Office suite? Well, it got its hands on Lotus Smartsuite in 1995, when it also got Lotus Notes.

IBM Docs allows organizations to collaborate on word processing, spreadsheets, and presentations. The plan is that there will only be a Web-based solution – no need for any browser plug-ins. In addition, its LotusLive has been rebadged as SmartCloud for Social Business. This provides users with easy access to social networking, file sharing, meetings, e-mail, calendars, and instant messaging.

The Web site at https://greenhouse.lotus.com/wpsgh/wcm/connect/lotus+greenhouse/lotus+greenhouse+next+site/home/labs/ibm+docs says: “IBM Docs is a new office productivity suite for working on documents, spreadsheets and presentations – together – in the cloud. With IBM Docs there is no desktop software. You only need a browser and an account, and you are able to easily create professional looking documents and share them with others. IBM Docs is simple yet powerful – letting you get started quickly, but delivering the advanced features you need. 

Once you’ve signed up, you can create and share documents, you can comment on documents, and you can assign parts of documents to teams to complete. In effect, everything you would look for in a cloud-based Office equivalent. Does it provide workflow features like Microsoft’s SharePoint? I don’t know the answer to that yet.

Will it work? It will be interesting to see. The linking with social networking is something that many enterprise organisations will find beneficial. There’s certainly room for another heavyweight to enter the fray. And it should be beneficial for us users if the big players offer more-and-more facilities for us to use as a way of keeping our interest and our business.

I’m sure we’ll be getting far more information about this initiative (and it is still in beta), but I thought it was worth noting now. Personally, I’d like to see a cloud version of the Adobe suite – InDesign, PhotoShop, Dreamweaver, etc.

More data stored off mainframes – user survey finding

The Arcati Mainframe Yearbook 2012 is now available for download from www.arcati.com/newyearbook12 – and it’s FREE. Each new Yearbook is always greeted with enthusiasm by mainframers everywhere because it is such a unique source of information. And each year, many people find the results of the user survey especially interesting. And this year, for the very first time, survey respondents indicated that, at their sites, more data was stored off mainframes than on.

This surprising result came from the 100 respondents who completed the survey on the Arcati Web site   between 1 November and 2 December 2011. 40% were from Europe and 50% from North America, with 10% from the rest of the world.

46% of the respondents worked in companies with upwards of 10,000 employees worldwide, while 10% of respondents had 0-200 staff, 6% had 201-1000, 28% had 1001 to 5000, and 10% had 5001-10,000 staff. In terms of MIPS, 34% of respondents had fewer than 1000 MIPS installed, 40% fell into the mid-sized category between 1000 and 10,000 MIPS, and 26% were at the high end.

Looking at MIPS growth produced some interesting results. Larger, more mature businesses (above 10,000 MIPS) were almost all experiencing some growth, but predominantly in 0 to 10% per year category. Sites in the 1000-10,000 MIPS range were showing a range of results with some sites suggesting a decline while others predicted growth of up to 50%. Sites below 1000 MIPS were experiencing a more complex future, with most expecting a small growth, but almost as many expecting no growth or negative growth (a business-speak euphemism for decline). The mainframe market does appear to be quite fragmented with competitive pressures at the lower end of the mainframe market, and some respondents commented about lack of understanding amongst management about the value of mainframe computing.

It was interesting to see that 6% of respondents had the zEnterprise z114s, with 19% having the z196s models installed. I expect that future surveys we’ll ask how sites are making use of the extra features on these models. Previous surveys have shown that there is a willingness amongst mainframes (especially larger ones) to purchase new models as they become available. In order to benefit from the new features

The big talking point during 2011 was cloud computing and whether mainframers really have been doing it since the 1960s and the impact of offering software (and anything else) as a service. The survey asked whether respondents currently used their mainframe for cloud computing. Just 12% (up from last year’s 2%) of respondents said they did. 34% said they didn’t, and the rest weren’t sure. It’s still early days for a cloud computing initiative to move off the PowerPoint slides and into the business environment, so the survey asked whether respondents were planning to adopt cloud computing as a strategy. 40% said they weren’t at present. Just 18% thought some mainframe applications would be cloud-enabled in the future. It will be interesting to follow these figures in future surveys.

The survey asked respondents which specialty processors (IFL, zIIP, and zAAP) they had. 16% of sites had all three (up from last year’s value of 6%) and a further 20% of sites had two of the three specialty processors (down from last year’s 28%). More sites had zIIP processors (48%) than any other. 36% had IFL processors, and 30% had zAAP specialty processors. 28% of sites don’t have a specialty processor installed.

The survey inquired about what proportion of enterprise data resides on the mainframe and what on other platforms. This produced, for the first year ever, the surprising result that more than half of the respondents use other platforms to manage the lion’s share of their corporate data. 44 percent of sites surveyed have more data on their mainframes, whereas 56 percent of the sites surveyed have more data stored on other platforms. Unfortunately, the survey was unable to drill down to find out why, but we can speculate that it may simply be the growth of data associated with the non-mainframe side of the business. It could be a result of the quantity of e-mails that organizations store for their staff. It could be that non-mainframe data is less well managed and ‘spreads’ into larger data sizes. Perhaps non-mainframe databases are less space efficient. Or maybe, people just create and save Excel spreadsheets and Word documents on Windows servers, where they wouldn’t keep equivalent files on mainframes. Or perhaps sites move their mainframe archive data off the mainframe, but still have it available online on, for example, a Linux distributed system. I’d be interested to hear yiour views on this.

The comments in the survey identified management ignorance of the power and benefits of using a mainframe. This is now a perennial reason given for the decline in mainframe computing within organizations. But cost was also highlighted as a factor mitigating against the successful growth of mainframe computing. One respondent suggested, “software costs are sinking the mainframe”.

Anyway, full details of the responses to many other questions can be found in the user survey section of the Yearbook. It’s well worth a read.

The Yearbook can only be free to mainframers because of the support given by sponsors. This year’s sponsors were: CA Technologies, Serena Software, Software AG, Software Diversified Services (SDS), Type80 Security Software, and William Data Systems.

The Arcati Mainframe Yearbook 2012 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 (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 simply what all those acronyms stand for, but 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 zJournal, INSIGHT-SPECTRA, 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. 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: Why incremental process-driven IT modernization is relevant for your business; Network management for the modern data centre; Next-generation mainframe management; Best practices for application release management; Peeling the onion of SFTP: options for securing file transfer to and from z/OS.

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 my next blog.

The other great thing about the Yearbook – as far as many of the 15,000 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: CA Technologies, Serena Software, Software AG, Software Diversified Services (SDS), Type80 Security Software, and William Data Systems.

To see this year's Arcati Mainframe Yearbook, click on www.arcati.com/newyearbook12. If you don't want to download a large PDF, again this year, each section is available as a separate PDF file.

Don't miss out on this excellent publication.

SharePoint 2007 site collection auditing

We start the year with another in our series of SharePoint hints and tips from our expert Darren Pritchard. This time he’s looking at how to sucessfully audit SharePoint site collections.

To enable/disable SharePoint auditing:

1. Open the site that you wish to audit
2. Click ‘Site Actions’
3. Select ‘Site Settings’
4. Click ‘Modify All Site Settings’
5. Under ‘Site Collection Administration’ you have ‘Site collection audit settings’
6. You would see Figure 1.
7. Here you can select what you wish to audit
8. Be very careful, SharePoint will not automatically purge these audit logs. They will continue to grow as long as they are enabled. I have seen content databases with 80GB of audit files!

Figure 1: Configure Audit settings page

To trim audit files:

1. Create the batch file shown in Figure 2. Note: CONTENTDATABASE is the name of the database within SQL.
2. Save it as ‘Purge Audit Logs.bat’
3. This will need to be run on your SharePoint Web frontend server as an Administrator. Do not be alarmed if it takes a little while to run. The time it takes depends on the amount of audit logs you are trying to trim.

SET STSADM="c:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\12\bin\STSADM.EXE"

%stsadm% -o trimauditlog -date -databasename

Pause

Figure 2: Purge Audit Logs.bat

I would suggest running this on a system without users because it may have an impact on performance.

If you have large amounts of audit log files, I would recommend running the trim command on a month’s worth of audit logs at a time. The SQL transaction log file will grow very large during the trim process.

Once you have trimmed the audit logs you will need to run a shrink database task within SQL to reclaim the space used during the trim process.

I'd like to thank Darren for his continuing contributions, and a happy New Year to everyone.
