• Digital Integration Hubs Emerge To Accelerate Transformations

  February 7, 2022 Alex Woodie

  A new design pattern called a digital integration hub is emerging to help organizations with legacy applications reap the benefits of digital transformation — not by moving off battle-hardened platforms and legacy ERP systems, but by piping data from them into a fast, new data store that interfaces with Web services.

  Former Gartner analyst Massimo Pezzini is credited with popularizing the digital integration hub (DIH) concept in 2019. The DIH essentially is a fast database, often implemented atop in-memory technology, that stores the data required to serve new applications implemented as part of a digital transformation project, such as big …

• No Plan To Support New Nav on Older IBM i Releases, IBM Says

  January 19, 2022 Alex Woodie

  IBM has no plans to support the new version of Navigator for i (i.e., “New Nav”) with older releases of the operating system, despite the existence of the severe Log4j security flaw in the heritage version of Navigator (“Old Nav”). The early, unexpected death of Old Nav also will hasten the adoption of New Nav for customers on current releases, and New Nav will become the default version with an update in March, IBM says.

  Earlier this month, IBM announced that no security patches would be forthcoming for Old Nav, which uses the Log4j code at the heart of a …

• IBM i Community Predictions For 2022, Part 1

  January 10, 2022 Alex Woodie

  While the month and year ostensibly are just values in the date field, when the calendar flips over from December to January, things feel different. There’s a greater sense of hope and optimism for what the new year will bring. Coming off another calamitous year filled with COVID-19, perhaps it’s we need that even more so this year.

  It has become an IT Jungle tradition to ask members of the IBM i community at the start of the year for their predictions. This year is no different, and so we’ll kick off the first part of our (most likely) two-part …

• Critical Log4j Vulnerability Hits Everything, Including the IBM i Server

  December 15, 2021 Alex Woodie

  Hackers gave themselves an early Christmas present this year with a critical security flaw in Log4j, a popular logging framework that is used across many programs, including some that run on IBM i. IBM i shops are encouraged to take this flaw very seriously, as the vulnerability already is being actively exploited in the wild. However, finding where Log4j exists in your stack is not always simple, which makes this particular flaw particularly nasty.

  The Log4j zero-day vulnerability, which was disclosed last week by security researchers with CERT New Zealand, was logged into the National Vulnerability Database as CVE-2021-44228 …

• Guru: Content Assist Plus in Run SQL Scripts

  November 29, 2021 Paul Tuohy

  By now, you should be well aware that Run SQL Scripts provides content assist (promoting) for Select statements (see Guru: ACS 1.1.8.3 Content Assist Includes Prompt For SQL! ). But did you know that you can also use content assist for stored procedures, table functions and parameters? Let’s see how it works, using some of the Integrated File System (IFS) procedures and functions provided by IBM i Services.

  Prompting a Stored Procedure

  Open Run SQL Scripts, type in:

  call qsys2.
  

  Then press F4 (or Ctrl+Space). You will be presented with a list of all the stored procedures in the schema …

• Security Threats, They Are a Changin’

  November 17, 2021 Alex Woodie

  Ransomware came into 2021 like a lion, but rather than going out like a lamb, it seemed to get bigger and meaner. Even IBM i shops, which so often are protected from the wider security storm, felt the panic and sense of helplessness of having their previous data held for ransom. But early indications are that the security threat we’re talking about this time next year may be entirely different.

  It’s tough to overestimate the impact that ransomware had on American businesses and other institutions through the course of the year. We had indications that something big was unfolding a …

• Consider Modernizing Your Approach to IBM i Security, Too

  November 10, 2021 Alex Woodie

  Many IBM i users are facing the reality that they need to modernize their IBM i applications, especially those based on monolithic blocks of fixed-format RPG. But other aspects of the IBM i experience can use some renovating too, including how organizations manage their security settings. Luckily, in the last few Technology Refreshes to IBM i, IBM has provided a slew of new SQL-based services for doing just that.

  Traditionally on IBM i, administrators had two main approaches for viewing and changing security settings. They could view and control the settings directly using commands, often automated through CL programs. Or …

• Guru: Abstract Data Types and RPG

  November 8, 2021 Ted Holt

  An abstract data type (ADT) is a type of data and a set of operations defined over that type of data. Using ADTs allows a programmer to work with data in terms of functionality rather than physical representation. The ADT is the basis of object-oriented programming. Does that mean that abstract data types don’t apply to procedural languages like RPG? Not at all. Quite the contrary.

  Before I show you how you can use abstract data types in RPG-based applications, let me further illustrate abstract data types with another, non-OO object — the user profile. The user profile is a …

• Technical Debt: The Silent Killer

  October 27, 2021 Alex Woodie

  There’s a dangerous malady afflicting companies that rely on the IBM i server to run their business applications. Left undiagnosed and untreated, it can debilitate an IT shop, rendering it unable to take advantage of new opportunities and respond to challenges. It’s called technical debt, and you or an organization you know may be suffering from it as we speak.

  Technical debt is a concept that is credited to Ward Cunningham, the American programmer and the co-author of Manifesto for Agile Software Development. “If you develop a program for a long period of time by only adding features but …

• The Mod Squad Comes Together to Modernize Old RPG

  October 6, 2021 Alex Woodie

  In the early 70s, a group of fictional social misfits joined up to solve crimes on the hit television series The Mod Squad. Now a group of real-life IBM i professionals of the same name are uniting to solve an equally pressing problem: modernizing old RPG code, including some that dates back to the 1970s.

  “You’ve heard of IBM‘s upward compatibility,” says Rich Ollari, an IBM i veteran who is one of the ringleaders of the new Mod Squad. “Code that ran back in the 80s, even the 70s, is still running today, and that’s what we’re fighting with. …
