New pseudo columns added for triggers

I have written before about how to create triggers, RPG trigger and SQL trigger, and as I have written more, and talked with other people, SQL triggers are the better trigger.

This has been reinforced an addition to Db2 for i (SQL) as part of the latest rounds of Technology Refreshes, IBM i 7.6 TR2 and 7.5 TR8, what have been called "trigger pseudo columns":

• TRIGGER_FILE_NAME:  File that caused the trigger to execute
• TRIGGER_FILE_LIBRARY_NAME:  The library that contains that file
• TRIGGER_FILE_MEMBER_NAME:  Member in that file

I am going to add a trigger to the DDS file TESTFILE. First, I need to "clone" the file to make the trigger output file. I can do this simply with SQL:

01 CREATE TABLE MYLIB.TESTFTRG AS 02 (SELECT * FROM MYLIB.TESTFILE) DEFINITION ONLY

ACS release 1.1.9.14 out now

On Saturday, August 8, my ACS alerted me a new release, 1.1.9.14, is available.

IBM's ACS page stated that the new release remedied some vulnerabilities that have been found in all prior releases of ACS, and a number of CVE security fixes.

There are no new enhancements included.

QCMDEXC scalar function can write to job log

The QCMDEXC SQL scalar function is one of my favorite SQL features. I have used it many times in my work, and here in articles on this website. As part of the latest Technology Refresh, IBM i 7.6 TR2 and 7.5 TR8, it is further enhanced by now being able to write the command performed to the job log.

QCMDEXC scalar function now has two parameters:

1. COMMAND:  The CL command to perform
2. PRINT:  Whether the CL command should be written to the job log. This can contain the following:
   • ERROR:  Only write to the job log if the command fails
   • NONE:  No command is written to the job log. This is the default
   • VERBOSE:  The command is always written to the job log

Before I start describing in details what this change does, I need to have something I can do using the QCMDEXC scalar function. In this scenario I have a DDL table, TESTTABLE, that contains a list of files that I want to delete using a Delete File command, DTLF, in this scalar function.

I can show the contents of this table with the following:

01 SELECT * FROM TESTTABLE

Handling pipe separated data into a Db2 file

It started with a question:

If my file.txt is pipe filed separated, how can I make the records fall into the physical file to the corresponding fields.

A good question. Most of the time my incoming files are comma separated. The same methods I would use for those will work for pipe separated files too.

First I need a file with pipe separators. I made a copy of some of the columns from my PERSON DDL table to an output file in QTEMP:

01 CREATE TABLE QTEMP.OUTFILE AS 02 (SELECT PID,LNAME,FNAME FROM PERSON) 03 WITH DATA

RPGPGM.COM-unity on the West Coast

I was at OCEAN’s TechCon26 conference earlier this month, and I was able to enroll a few more people into the RPGPGM.COM-unity. You can see who these people are here.

If you see me at an IBM i event feel free to introduce yourself to me, ask for your own RPGPGM.COM-unity ribbon, and you will become part of this community. All I ask in return is a photograph of you with it.

It is now so easy to view CVE using SQL

Before I start describing how to use this new SQL Table Function, I need to explain what CVE are.

Common Vulnerabilities and Exposures, CVE, are standardized, publicly identified cybersecurity flaws in software or firmware. When IBM, or a researcher, find a flaw in IBM i, or related software, it is given a unique id. These ids are cataloged globally by the MITRE Corporation, and published with their severity and impacts.

You can learn more about CVE on IBM's "What is CVE?" page.

I cannot find a CL command that allows me to view CVE details. I would have to search for a particular CVE using the IBM Product Security Central page.

With the latest Technology Refreshes, IBM i 7.6 TR2 and 7.5 TR8, is a new SQL Table Function that allows me view, and search, all of CVE from my IBM i partition.

The CVE_INFO Table Function is found in the library SYSTOOL, it has one parameter the IBM i release number. I went through and checked for each release to find that V5R3 is the earliest there are results for:

First Technology Refreshes of 2026 released today

The PTFs for the Technology Refreshes, IBM i 7.6 TR2 and 7.5 TR8, announced two weeks ago are released today.

When you ask your Sys Admin to download and apply the PTFs don't forget to tell them that they need to download the latest PTFs for Database (Db2) and RPG too.

I am looking forward to "playing" with all the new and enhanced features added, and will be writing about them here, on RPGPGM.COM.

Program to alert when elapsed CPU percentage becomes too high

When I published my article about Program to alert when jobs' CPU percentage becomes too high someone messaged me asking could I think of something that would do the same when the total CPU exceeded a certain percentage. The answer is, of course, "Yes".

Before I create a program we need to consider the whether the partition that the program will be run on is "capped" or "uncapped". What does that mean?

When a partition is capped it cannot use more than its allocated processing units, in other words it can never exceed 100% CPU usage.

While an uncapped partition has its base entitlement of the processing units, but can borrow unused processing power from the other partitions if available. This means that its CPU usage can exceed 100% of the partition's resources.

This means that 90% CPU utilization could be more concerning on a capped than an uncapped. Keep this in mind when you look at my example program.

I always use ACS's Run SQL Scripts, RSS, to develop the SQL statements I will be including in a RPG program. I can get the elapsed CPU percentage from the SYSTEM_STATUS SQL table function:

New model of IBM Power 11 announced

Along with the announcement of the latest Technology Refreshes came another announcement for the smallest of the IBM Power11 servers, S1112.

I am not a hardware geek, more of a software one, but having read the announcement document I think it is something worth reporting upon.

S1112 is in the P05 software tier that can run IBM i AIX, Linux, or hybrid workloads on one server.

It comes in two configuations:

First TR of 2026

The deferred first Technology Refreshes of 2026 PTFs, IBM i 7.6 TR2 and 7.5 TR8, have been announced.

The first thing I do when any new TR announcement is made is to check out what enhancements have been made to Db2 for i (SQL) and RPG. Do note that there are a number of changes and additions made to IBM i 7.6 that have not been made to 7.5.

The SQL that have caught my eye are:

Spring 2026 Performance Guide available

A new version of IBM's "IBM i on Power – Performance FAQ" was published at the beginning of this month, and is available for download.

The guide provides us with tips on how to measure, and improve, the performance of your IBM Power server, IBM i partitions, Db2 database, and programs that run within it.

You will find the document here.

I always download it and read the passages I feel are relevant to my situation. I recommend you do the same.

More information regarding IBM Bob Premium Package

IBM made an announcement yesterday, Thursday July 9, with more information about the new IBM Bob Premium Package for i. This includes some more information about the additions to it.

I am not going to repeat what is says. Just provide you with the link to it here.
