• Guru: Beware of SQL Precompiler Variables

  September 26, 2022 Ted Holt

  In a famous Henny Youngman joke, a patient says, “Doctor, it hurts when I do this,” to which the doctor replies, “Then don’t do that.” Corny jokes aside, I have spent decades trying to identify programming practices that hurt when I do them, and having identified them, cease to do them. A case in point is the misuse of the variables that the SQL precompiler defines in my RPG programs, variables such as SQLCODE, SQLSTATE, and SQLER3.

  “So what,” I hear you ask, “is the problem with these variables? ” Well, they’re global, and global variables are evil.   Global …

• Guru: Regular Expressions, Part 2

  August 15, 2022 Mike Larsen

  In the first part of this series, I showed how to replace characters in a string using SQL and regular expressions. This time, I’ll show other regular expressions that are available for us to use. The regular expression functions I’ll show are REGEXP_COUNT and REGEXP_LIKE and the examples come from production programs that I’ve recently implemented.

  In the first example (Figure 1), I want to get a count of the number of occurrences of a pattern within a string. To make this more interesting, I’m searching for two different patterns within a sting. To accomplish this objective, I used …

• Guru: Regular Expressions, Part 1

  July 25, 2022 Mike Larsen

  In the first part of this series, I will show how to replace characters in a string using SQL and regular expressions. I know I can replace characters using RPG or SQL, and they work great, but there are some cases where I find using regular expressions is a bit easier.

  For the examples I’ll show, I’m using the REGEXP_REPLACE function. REGEXP_REPLACE allows me to search for a particular value within a string and replace it with another value.

  In the first example (Figure 1), I want to search a string that has both letters and digits and I want …

• What Happens To IBM i In A “Zero Datacenter, Zero Mainframe” FedEx?

  July 18, 2022 Timothy Prickett Morgan

  Federal Express, the pioneer in overnight document delivery for business founded in Little Rock, Arkansas, in 1971 by Frederick Smith, did not start out in the ground shipping business. But it did start its datacenter operations on IBM mainframes, as any company needing complex and intense computing would at the time, and it chose Memphis, Tennessee, in the heart of America, as its headquarters and base of operations in 1973 when the company moved from a PhD thesis at Yale University to a true business.

  In 1983, FedEx made history by being the first company in the United States to …

• Guru: IBM i Experience Sharing, Case 5 – Using IBM i PDI Charts To Answer Performance Questions

  July 18, 2022 Satid Singkorapoom

  During my long career as an IBM i performance specialist, it was natural for people to ask me performance-related questions of various kinds. But in many cases, it seemed to me that the customer could not understand my answers, and I could not provide supporting evidence due to the lack of a performance reporting tool that could produce easy-to-understand explanatory information. The situation changed for the better with the availability of IBM i Performance Data Investigator (PDI) tool as of release 6.1. I would say that the PDI tool provides charts of information that resemble those used by business people …

• Exploring Security Applications for IBM i OLAP

  July 13, 2022 Alex Woodie

  The IBM i platform is typically thought of as a transactional server, and it does that job very well. But it also has solid analytical capabilities, thanks in large part to new OLAP features added many years ago with IBM i 7.3. Now the platform’s database guru, Scott Forstie, is looking for ways to promote greater use of these OLAP capabilities, and security is emerging as a top application.

  Sometimes it takes a while to figure out what a good thing you have. This appears to be the case with IBM i 7.3, which launched way back in 2016 and …

  In recent weeks, IBM has disclosed a handful of vulnerabilities in its IBM i operating system and related IBM i products, including Db2 Mirror, WebSphere, Navigator for i, the Java development and runtime tools, and OmniFind Text Search Server.
