Know Your PTF Group Level Currency In 30 Seconds Or Less!
August 4, 2015 Larry Bolhuis
… Read moreThe IBM i is one of the easiest to maintain operating systems going. A big part of that is because IBM provides the hardware, operating system, and updates. Clearly the number of permutations are reduced dramatically. In addition, some problematic areas, such as video drivers, simply don’t exist in IBM i. So that’s it then, no need to update because we live in Utopia, right? Well, not so fast!
Just because IBM provides all the pieces doesn’t mean they are either perfect or complete. Besides, there are many components and these are constantly being updated. Two examples are node.js and

Where Do Library Lists Reside?
August 4, 2015 Ted Holt
… Read moreI often sit and ponder the mysteries of life. For example, why do some people use C to write business applications? Why does the text of message SQL6789 end in a period instead of a question mark? And, recently, why do people circumvent powerful features of the robust IBM i operating system? Let me show you what I mean.
The circumvented feature that is on my mind at present is the library list. In case you’re new to the IBM i world, the library list is a list of libraries that the system searches when looking for an object. It’s

An Introduction To Processing XML With RPG, Part 1: The Basics
August 4, 2015 Jon Paris
… Read moreNote: The code accompanying this article is available for download here.
RPG IV’s built-in XML support has been available for some time now, having been originally introduced with V5R4 back in 2006. Due to deficiencies in that release, many RPG’ers chose not to use RPG to process XML. Fortunately, IBM has corrected those deficiencies, and RPG provides a smart way to read XML. Here’s how it’s done.
In that first release, the most powerful of the op codes, XML-INTO, had some gaps in its support that sometimes made it difficult to use without pre-processing the XML. In addition, the

Strong Dollar Hurts Power Systems Sales In Q2
July 27, 2015 Timothy Prickett Morgan
… Read moreIt is a story that every big multinational public organization is telling as they reveal their financial results for the second quarter of the year. Economic uncertainty in parts of Europe, South America, and Asia have pushed up the value of the U.S. dollar relative to the other currencies, which is great if you are an American traveling. But if you are an American corporation bringing a big chunk of your overseas sales back home for financial reporting, it is not so much fun.
Such is the case with IBM‘s Power Systems line during the quarter ended in June,

How Much Temporary Storage Is In Use And Who Is Using It?
July 21, 2015 Pete Massiello
… Read moreI recently visited the site of a company that had a problem of increasing disk utilization. The staff had run all the GO DISKTASK reports and nothing seemed to be getting bigger. Unfortunately, there hasn’t been an easy way of finding who is using temporary storage. Displaying the amount of used temporary storage was so obscure that most System Administrators had no idea where to look. Let me show you how to see: (1) the amount of temporary storage that is being used; and (2) the jobs are using the most.
Temporary storage is mostly associated with jobs on your

Clamoring For Attention
July 21, 2015 Ted Holt
… Read moreYou know how to send a message to the system operator message queue. Here’s some code you can use when you need that message to stand out.
Here’s the CL code.

IBM’s Migration Plan To PurePower Systems
July 13, 2015 Timothy Prickett Morgan
… Read moreMore than anything else, IBM is a systems company, and it always has been. We could argue about whether or not Big Blue should have ever exited the application software business, as it started to do in the late 1980s and finished off doing in the early 1990s, but I don’t think there would be much of an argument that IBM has been and should continue to be a supplier of full systems of servers, storage, networking, and systems software like operating systems, middleware, and databases.
Thankfully, even IBM does not seem to be of two minds about this, as

Security Architecture For Business Applications
July 7, 2015 Patrick Botz
… Read moreDevelopers can make it infinitely less complex to manage the security of a system and can significantly improve the security of any computer system by following a simple architecture in their applications. Conversely, not following a similar architecture makes it virtually impossible for any administrator to both maintain the best security possible and avoid failed and crashed applications.
Nearly everyone in most IT shops assumes that it is the system (or security) administrator’s responsibility to manage access control for the data on the system. They also assume it is the administrator’s responsibility to fix any authority failure issues encountered by

How To Create Updateable Views
July 7, 2015 Ted Holt
… Read moreIt has been said that perception is more important than reality. I agree, especially when such perception is implemented as a view in a relational database. When creating a view, it is good to keep two things in mind.
First, consider that a view may be updateable or read-only. An updateable view allows the user to update rows in the table through the view, but also to insert new rows and delete rows. Read-only views may only be used when retrieving data. Both types of view are superb, and each type has its uses.
One strong advantage of updateable views

Looking For Stuff With iSphere
July 7, 2015 Susan Gantner
… Read moreIn my last tip I introduced you to the iSphere RDi plug-in. In this tip I’ll cover a few other features in iSphere that I find very useful. This time I’ll focus on a couple of options within iSphere that can help you search for things and subsequently edit them. The two things we’ll be searching are source members and message files.
Looking For Stuff In Source Files
Let’s start out with the iSphere Source File Search. This is a feature similar to PDM’s option 25 – Find String Using PDM (FNDSTRPDM). It lets you search for a string of
