We’ve been hearing from clients wondering whether they need commercial connectors to integrate open source technology with Db2, RPG, and COBOL data.
Liam Allan has shown the power of using open source tools that are available to everyone. He recommends accessing IBM i business logic and data using open source tools, without proprietary connectors.
We regularly turn to the IBM i (SQL) services that Scott Forstie’s team at IBM has been delivering. We love using them to get specific jobs done faster!
What’s not to love? SQL is a universal interface, based on IBM i’s revered crown jewel, Db2 for i. Code once, use many times from every conceivable kind of technology—on the box and off. Brilliant!

In recent years, Db2 for i Business Architect Scott Forstie and his team have rapidly strengthened the IBM i database, improving the sophistication of its SQL query engine, and adding to its galaxy of IBM i services. What’s more, they have several years’ worth of new enhancements in the pipeline.
CIOs and IT Directors can meet Scott at the CIO Summit on March 25, 2019, Charlotte, North Carolina, for an IBM i strategy briefing.
Presentation HandoutThe ever-expanding capabilities of Db2 for i can simplify development in open source languages such as PHP, Ruby, Node.js (JavaScript), and Python. These languages, known for their effectiveness in building web and mobile applications, can tap into the power of SQL.
So why complicate them with repetitive code that distracts from their power and simplicity?
Now that speedy PHP 7 is available for IBM i, we’ve been helping clients upgrade to this long-awaited release. Here are some resources for performing this popular upgrade.
It’s not always easy to locate the official documentation for all features of DB2 for IBM i. Using Google Search is hit or miss, with full-text searches often bringing irrelevant results from other varieties of DB2 or from older versions. Many people don’t know that complete reference manuals are available for almost every aspect of DB2 on i.
In just two weeks I’ll have the pleasure of joining some of the top IBM i development experts in Orlando for the RPG & DB2 Summit. Run by Susan Gantner, Jon Paris and Paul Tuohy, this conference is full of big personalities who create a warm, friendly environment that’s perfect for learning.
I enjoy the community feeling and how excited everyone is to solve development problems and share tips and techniques.
The RPG & DB2 Summit is one of the few training events that focuses exclusively on topics of interest to IBM i developers. That includes PHP and SQL, of course!
Check out the session grid and pay special attention to the Hands-on PHP Workshop on Monday, March 20, followed by several PHP and open source sessions given by yours truly and Zend’s Mike Pavlak, plus a whole array of SQL sessions. And maybe a few on RPG.
I think they should change the name of the conference to the RPG, PHP, SQL & DB2 Summit, don’t you?
Come join us!
The 2015 COMMON annual meeting and expo, now in its first day, is helping speakers and attendees create innovation through IBM i integration: open source, closed source, IBM and vendor solutions. For example, of my six presentations during this conference, two are collaborations:
The Art of Performance Diagnostics, with IBM’s Dawn May, allows us to show, among other topics, how IBM i’s integrated performance tools complement green-screen tools and third-party tools (in this case, Zend Server) to pinpoint and solve performance issues (here, PHP-and DB2-based applications).
PHP Tricks for RPG Developers, a talk jointly created by RPG and SQL expert Birgitta Hauser and me, combines RPG, PHP, and DB2, allowing RPG to achieve graphical (charts and graphs, PDF and Excel files) and internet (json-based web services, flexible email) functionality using native functions.
Conferences such as COMMON serve a need that’s difficult to replicate back at the office—brainstorming and sharing possibilities among interdisciplinary peers, or sitting side-by-side with like-minded colleagues who work for different employers, to try something new. This week, for example, some of us plan to share knowledge on compiling binaries in PASE and to further the potential of open source on IBM i. I’m looking forward to presenting my talks (both joint and solo) and helping to realize new ideas with forward-looking colleagues during the conference.

Between major IBM i releases, IBM ships frequent enhancements using the Technology Refresh (TR). Particular features are present with specific TR levels. SQL offers an easy way to identify the latest TR level on an IBM i system.
IBM i services comprise a collection of DB2 and SQL objects that provide a wealth of system information. The GROUP_PTF_INFO view will display an IBM i’s TR level to the user who runs this SQL:
|
1 2 3 4 5 |
SELECT CURRENT SERVER CONCAT ' is running ' CONCAT PTF_GROUP_TARGET_RELEASE CONCAT ' with TR level: ' CONCAT PTF_GROUP_LEVEL AS TR_LEVEL FROM QSYS2.GROUP_PTF_INFO WHERE PTF_GROUP_DESCRIPTION = 'TECHNOLOGY REFRESH' AND PTF_GROUP_STATUS = 'INSTALLED' ORDER BY PTF_GROUP_TARGET_RELEASE, PTF_GROUP_LEVEL DESC LIMIT 1; |
When run on my server, the result was a single column, TR_LEVEL, with the value:
|
1 |
SEIDENI is running V7R2M0 with TR level: 3 |
Time for me to upgrade, yes?
Here is my original post with older techniques:
I recently needed to know if a client’s IBM i 7.1 system had Technology Refresh 4 (TR4). If it did, I could use the relatively new INSERT with remote SUBSELECT technique, which allows a single SQL statement to copy DB2 data from one partition to another. Such are the benefits of keeping current with Technology Refreshes.
After reading an article on TRs by Steve Will, I decided to document how to determine which TRs are installed on an IBM i system.
TRs, which were introduced with IBM i 7.1, are packaged as Program Temporary Fixes (PTFs). They can be found with the DSPPTF command.
First, determine the product number of the licensed internal code of your system. For 7.1, the product number is 5770999.
Then use the DSPPTF command followed by this product number. For example:
|
1 |
DSPPTF 5770999 |
When run on my test system, this command produced a list of PTFs that included MF99007, MF99006, MF99005, MF99004, MF99003, MF99002, and MF99001.
Because Technology Refresh PTF numbers follow the format MF99nnn, where nnn is the TR number (bolded above), I knew that TR7, TR6, TR5, TR4, TR3, TR2, and TR1 were available. I was pleased to learn I could use TR4’s enhancements to DB2.
