June 2017 Newsletter
Greetings iTech Fan,
i can do anything with iTech Solutions
As we come upon the end of June, we are approaching the vacation season here in the US. I hope you get to enjoy your summer. The first half of this year I can summarize with meeting customers. Whether it was at the many conferences we were exhibiting at, conferences we were speaking at, technical roadshows we did, or at customer locations, we saw so many customers during the first 6 months. Certainly, one of the highlights of my job. I do enjoy meeting and talking to customers, as do all the others here at iTech Solutions. It is always interesting hearing what they are doing.
The first half of 2017 (wow, where does time go that 2017 is now 1/2 over?) has seen us add additional staff, increase and expand the IBM i services that we are delivering, and continue to grow our remote System Administration services. Look for us to continue to grow those areas, and you will be seeing our new video series start to unfold during the summer. We will be starting with a video series of IBM i System Admin Tips and Techniques. I don’t think we will win any Oscars, but we will certainly make your life easier with these short videos.
The 2017 iTech Solutions IBM i State of the Union was completed in the beginning of May, and I hope you had a chance to read about where we see the platform currently, and predictions for the future. We have gotten some great feedback already from those who have read the 2017 State of the Union. Check out the iTech Solutions video on our 2017 IBM i State of the Union and later on in this newsletter you will see a link to read the entire document. Turn up your speakers, and click here, or the image below to watch the video.
This issue of our newsletter has 6 articles. The first article is on iTech Solutions 2017 IBM i State of the Union. The second article is on changing the subsystem that your ODBC jobs run in. The third article by Steve Pitcher is about Quickly Finding Large IFS Objects. The fourth article is a reprint of Pete’s Perspective in this month COMMON Connect newsletter. The fifth article lists some of the upcoming events in which iTech Solutions will be participating. The last article is for your reference with updated PTF information. Please note that for all 7.1 customers that are on the Quarterly or Semi-annual iTech Solutions PTF maintenance plan, we will be installing the latest PTFs as you are most likely now on Technology Refresh 11. For the 7.2 customers, we will be installing 7.2 Technology Refresh 6, and 7.3 will be Technology Refresh 2.
Some notes on the latest HMC release:
- HMC V8 R8.6.0 will be the last release to support POWER6.
- HMC V8 R8.6.0 will be the last release to allow ‘classic’ UI login (Not happy with that decision).
- HMC V8 R8.6.0 will be the last release that supports the model CR5, CR6 and C08.
- The HMC must be at version V8 R8.4.0 or later to be upgraded to HMC V8 R8.6.0. This requirement is enforced during installation.

IBM i State of the Union.
Last year we published our first annual iTech Solutions IBM i State of the Union looking at where the platform has been over the years and seeing what directions it is moving in. Being in touch with members of the IBM i community by visiting customers weekly and attending conferences provides the insight into what shops are doing. One thing is certain, no one is standing still. The IBM i (once known as the AS/400, iSeries, or System i) is still going strong; new applications are being developed, existing ones expanded and modernized, while integrating with a myriad of external sources. Those utilizing the capabilities of the system are forward thinking, innovative companies. Unfortunately, there are still companies trapped in the year 2000. There is a mix of both in this community, but we are seeing more of the former investing in their IBM i and upgrading to utilize the functionally the platform has to offer. Later, we will discuss both these types of organizations as they are interesting and affect us all, as professionals in this industry.
For over 29 years IBM i has gained a well-deserved reputation for security, reliability, and performance which is unbeaten. This is due to the tightly integrated and tested systems delivered by IBM Rochester remaining committed to the calling of being “easy to use and administer.” There is a persistent perception that businesses have moved away from the platform attributed to application availability, green screens dated reputation, emergence of other technologies, and potential lack of skilled professionals. However, companies should be aware this isn’t your grandfather’s AS/400. The playing field has changed. Making business decisions based on antiquated notions of this system being a “has been” is a disservice to the organization and the professionals supporting it. This is often seen……….

Changing the default Subsystems that your ODBC jobs run in.
Have you ever wanted to move certain users or maybe all your ODBC jobs into a different subsystem? The ODBC jobs normally run in QUSRWRK. There is a command that was introduced in 7.1 TR11 & 7.2 TR3 that will accomplish this for you. This is a great command if you are having some performance problem with ODBC jobs, or perhaps you want to control how much resources those jobs are taking up. You can use this with QRWTSRVR, QZDASOINIT, or QZRCSRVS servers.
The program is SET_SERVER_SBS_ROUTING and it will do just that. The SET_SERVER_SBS_ROUTING procedure provides the ability to configure some servers to utilize alternative subsystems based on the user profile that is establishing the connection. The user profile can be a group profile or a supplemental group profile.
This procedure allows an administrator to reposition specific users into alternate, non-default, subsystems. When configured, new incoming TCP/IP server connections will use the alternate subsystem. If the server is configured to route to a user-specified subsystem by incoming TCP/IP address as well, the job will first route to the subsystem configured for that TCP/IP address and then immediately attempt to route to the subsystem configured for the connecting user profile.
Here is an example of making new incoming Database server TCP/IP connections for user profile PETEM to route to subsystem ITECHSBS.
The user calling this procedure must have *SECADM special authority. The alternative subsystem must be configured so the Prestart Job Entry name matches the subsystem name. This is a great way to control the jobs on your system. For more help with performance, or other system issues contact iTech Solutions.
There are many ways to analyze your IBM i storage. With QSYS objects, it’s a simple matter of running a RTVDSKINF (Retrieve Disk Information) and analyzing the output of table QAEZDISK in QUSRSYS, or print a disk usage report with PRTDSKINF. The IFS can be analyzed a number of different ways but the most common way is to run a RTVDIRINF (Retrieve Directory Information) and then analyze the results with SQL. RTVDIRINF is a very powerful command because you can then analyze everything in the IFS including QSYS objects.
Sometimes you have to find out file size information but time or available disk space isn’t on your side. Below are two ways to get IFS object size information quickly:
In Qshell, you can use the Find command to list files that meet the search criteria. For instance, the command below will list the contents of the root directory and all subdirectories that are greater than 1 Gigabyte.
find / -xdev -size +`echo 1024*1024*1024 | bc`c –ls
The result set looks something like this after being entered into Qshell:

The –xdev parameter ensures that this find operation will only search underneath the IFS component of the root file system (skipping /QSYS.LIB, etc.). You have to do a little math in order to calculate the byte size. If you wanted to find a smaller size set of objects, you could echo 1024*1024*500 and it would be the equivalent of finding anything 500 MB. If you wanted to find files that were 20 GB, you would echo 1024*1024*1024*20.
If you’re really looking for a quick and dirty script, you could always run the following into a QP2TERM shell. It will only show the size of the contents of the current directory and the total size of subdirectories. Handy info if you want to drill down and find where the big files are hiding.
for i in *; do du -sk “$i”; done 1>/home/IFS_size.txt
You just need to CD to a directory, run the script and then it will create a text file underneath the /Home folder.

Pete’s Perspective: From Time Warp to the Future.
This is my article that I wrote for the COMMON Connect magazine this month June 2017.
I was at a client two weeks ago and thought I had traversed through a time machine. The entire company was stuck in the 80s. Unbelievably they had an integrated ERP system running on an actual AS/400! Nothing had been upgraded in years, if not decades. The employees were knowledgeable and the well-integrated ERP system was running the entire company. However, nothing was from this century. The programs were S/36, the data unusable via query, processing was slow, and everyone was running windows 98 on their desktops. I expected Austin Powers was going to come out of a room at any moment yelling, “Groovy baby.” I asked about their systems and education opportunities for the staff, not surprising no one could remember the last time anyone invested in their skills. In fact, they didn’t even know about COMMON.
I started to tell them about features and functionality of IBM i 7.2 and 7.3 and it was unbelievable this was the same platform running their business. It felt like telling a grandparent about their grandchildren’s accomplishments with mobile technology. Eyes were popping out of heads at the thought of all the untapped potential. What I talked about they thought was the future of business computing and in reality it is currently available.
This is why the IBM i has a perception problem.
I was at the COMMON Annual Conference this past May in Orlando and had a chance to talk with so many people, as always it was great. I presented five sessions and had wonderful opportunities to meet old and new friends throughout the conference. Personally, I learned much from discussions covering what is happening in all the varied shops comprising our community. Additionally, I enjoyed a few sessions between my duties as a volunteer and working my booth in the expo. The first session on Sunday I attended was IBM i and IBM Watson covering the application interfaces for connectivity and transition of data. IBM Watson, which will forever be known as the computer “who” beat Ken Jennings in Jeopardy, has passed the medical boards and is being used commercially to help doctors with diagnosing illnesses. Pretty impressive! Not surprising the room was filled to overflowing and a repeat was added later in the week.
I was extremely skeptical at first and thought, “let’s see how difficult this will be.” Logically I figured there would need to be some crazy interface or language in play. Then I realized, holy &*%#$ this is just too easy and being accomplished with RPG to boot! This is one of the benefits of education; it opens your eyes to new technology and what is out there and how it is shaping the world we live in. Now, most people who know me know that I am a system admin who can’t spell RPG however I found the examples being presented easy to follow.
After the session I wanted more information so I went to the IBM booth in the COMMON Expo. Instead of just telling me about Watson they had a demo. As we were in Universal Studios it was fitting that Watson was powering a Harry Potter Sorting Hat. The newest Hogwarts denizen was asked various questions, with tone and demeanor accounted for, and Watson branched into other inquires before putting you into your House. This was true cognitive computing capabilities using visual recognition, feeling detection, and more. Very cool using Watson for an actual application directly from my IBM i.
Cognitive Systems rely on collections of data and information. Looking around the world today data is no longer just in tables and files. The proliferation of different types of information requires new ways to analyze and query this flood.
I thought this technology would be cost prohibitive for anything other than large organizations however it was a pleasant surprise that small companies, even individuals, could afford to use Watson. Additionally, it was so easy to sign up for an account. I have said many times before this isn’t your grandfather’s AS/400 but if you are trapped in a time warp you might not know what power awaits your organization. For those of you back in the 80s and 90s it’s time to break out of your bubble and see what the IBM i offers your world. Not just Watson but everything else this machine can do.
An excellent place to learn about all the features and functions comprising the IBM i is the annual COMMON conference. Other opportunities are the upcoming virtual conference that you can attend from right at your desk, followed by the fall event October 1st to the 4th in St. Louis. If you are hanging with Austin Powers more than a few days of education might be needed but this is a great start. Even if you consider yourself up to date the innovation rolling out from IBM Rochester regularly is a reason for everyone to invest in their skills.
Now is the time to start, in a few years you don’t want to feel your career is stalled in the past. Or worse, be over.

People are always asking me how often they should be performing PTF maintenance, and when is the right time to upgrade their operating system. I updated this article from last month with the current levels of PTFs. Let’s look at PTFs. First, PTFs are Program Temporary Fixes that are created by IBM to fix a problem that has occurred or to possibly prevent a problem from occurring. In addition, some times PTFs add new functionality, security, or improve performance. Therefore, I am always dumbfounded as to why customers do not perform PTF maintenance on their machine at least quarterly. If IBM has come out with a fix for your disk drives, why do you want to wait for your disk drive to fail with that problem, only to be told that there is a fix for that problem, and if you had applied the PTF beforehand, you would have averted the problem. Therefore, I think a quarterly PTF maintenance strategy is a smart move. Many of our customers are on our quarterly PTF maintenance program, and that provides them with the peace of mind of knowing their system is up to date on PTFs. Below is a table of the major group PTFs for the last few releases. This is what we are installing for our customers on iTech Solutions Quarterly Maintenance program.
The easiest way to check your levels is to issue the command WRKPTFGRP. They should all have a status of installed, and you should be up to the latest for all the above, based upon your release. Now there are more groups than the ones listed above, but these are the general ones that most people require. We can help you know which group PTFs you should be installing on your machine based upon your licensed programs. Here is a nice tidbit. The Cumulative PTF package number is broken down as YDDD, where Y is the year and DDD is the day it was released. Therefore, if we look at the cumulative package for V7R1, the ID is 16120. We can determine that it was created on the 120th day of 2016, which is April 29th, 2016. Look at your machine and this will give you a quick indication of just how far out of date in PTFs you may be.
If you have a Hardware Management Console (HMC,) you should be running:
|HMC (CR4 last release)||V7R7.9||
If we have a model listed above in the HMC column that is the highest level of firmware that model of the HMC can be upgraded to.
- Note that release 8.8.x does not support any POWER5 servers.
- Version 7.7.9 is not supported as of 12/30/2016 and cannot be installed on HMC models C03, C04 or CR2.
- If an HMC is used to manage any POWER7 processor based server, the HMC must be a model CR3 or later model rack-mount HMC or C05 or later desk side HMC.
- HMC V8R8.1 is supported on rack-mount models CR5, CR6, CR7 and CR8; and on desktop model C08. These listed models meet or exceed the V8R8.1 minimum memory requirement of 2GB however 4GB is recommended.
- If you want to manage a POWER8 machine, you need to be on at least HMC 8.8.1
Some notes on the new HMC release V8R8.6 that just came out:
- Will be the last release to support POWER6.
- Will be the last release to allow ‘classic’ UI login.
- Will be the last release that supports the model CR5, CR6 and C08.
- The HMC must be at version V8 R8.4.0 or later to be upgraded to HMC V8 R8.6.0. This requirement is enforced during installation.
If you have a Flexible Service Processor (FSP) your firmware should be:
|Power5 or 5+||520, 515, 525, 550, 570||SF240_418_382||last|
|Power6||940x, M15, M25, M50||EL350_176_038||last|
|8203-E4A, 8204-E8A, 8204-E4A||EL350_176_038||last|
|MMA, 560, 570||EM350_176_038||last|
|Power7||8231-E1B, 8202-E4B, 8231-E2B, 8205-E6B, 8233-E8B, 8236-E8C||AL730_152_035|
|8231-E1C, 8202-E4C, 8205-E6C||AL740_161_042|
|Power7+||8231-E1D, 8202-E4D, 8231-E2D, 8205-E6D||AL770_112_032|
|Power8||8408-E8E, 8284-21A, 8284-22A, 8286-41A, or 8286-42A||
|9119-MHE or 9119-MME||SC860_082_056|
