AIXpert Blog is about the AIX operating system from IBM running on POWER based machines called Power Systems and software related to it like IBM Systems Director, PowerVM for virtualisation and PowerSC for security plus performance monitoring and nmon
This is part 2 of Systems Director licensing or at least working out what you are doing with System Director that requires a license. In part 1, we looked at listing (via the command line) the POWER machines that Systems Director was connected too. This time we what to find out the machines that Active Energy Manager (AEM) is controlling. Once you have installed AEM it is tempting to start monitoring and controlling all your Power Systems electrical use and temperatures but you should only use AEM if you have a license for AEM for each...

In case, you did not notice (as its the silly summer season) AIX 7 is shipping in 19 days time. See the official AIX 7 Announcement Letter for all the details This is a whole 2 months early - well done guys.
At a recent POWER & AIX Workshop, I was challenged when I stated that you can download IBM Systems Director (ISD) and run it at no costs. Granted: If you want IBM Support for ISD functions then you do need to purchase the license and SWMA for every endpoint (think HMC and every core of any machine that ISD is controlling). Compared to other systems management tools (I have worked with in the past) the ISD prices are very low so its worth asking for the local currency price. I also think most people (including myself) will get stuck on... [More]
Following on from my previous AIXpert blog on 1st July 2013 - "Core files filling important filesystems? Want email alerts about each core dump?" it was pointed out to me by AIX guru Mathew Accapadi that we can for many years use the ODM and AIX error reporting framework to send emails on the generation of core files. See the previous blog on how to force the core files to a particular directory - and not allow them to fill up important system directories. On the alternative reporting method see below:

There were a number of announcements made today by Power
Systems including new hardware features, a new platform management console, and
new PowerVM virtualization capabilities.
Two new Power Systems blade servers were announced, the PS703 and PS704 . The PS703 blade supports up to 16 processor cores in a single
BladeCenter slot and the PS704 supports up to 32 cores in a double-wide
blade. The PS703 and PS704 also support
a new solid state drive option.
The Power 750 Express server has new processor options or 4, 6 or 8
We have all heard the old story of a computer company that was so successful that is had to move to smaller premises! The point being that they upgraded the computers to much smaller but more powerful ones and did not need the floor space. Well, it is happening to me! My Advanced Technical Support group are moving from IBM Bedfont Lakes (near Heathrow), UK from building 2 to building 3. That might not sound like much and it is only a stones throw away but we are going from 10 racks down to 3 racks. The old POWER5 machines that were not... [More]
I regularly get asked a question like: I have 4 months of data from 25 machines and have to develop a Capacity Planning model to size these LPARs on to new machines but I am having problems with having so much data. What can you recommend? We need graphs of
CPU compared to Entitlement
CPU Physical CPU use
Maximum real memory use
Sometimes this data is needed as input in to the Workload Estimator tool or Server Consolidation tools.
I am getting asked more about security these days than in the previous decade - perhaps there is renewed focus on this area as we hear about hacker groups taking what they want from organisations and companies in the News every day. Below is an answer I gave to a recent email question on what AIX offers on the security side, spotting vital files being changed and what parts of PowerSC to use for quick wins.
For AIX security the three big hitters for "out of the box" AIX hardening are:
Ditch telnet/ftp in the... [More]
In case, you missed it : AIX became 25 years old, today . AIX is IBM's name for their UNIX, it stands for Advanced Interactive eXecutive and based on AT&T's UNIX System 5.2 and 5.3. I was not at the launch of the IBM RT (the computer on which it ran) but I know people that were apparently there was a lot of dry ice on the stage. Nor was I with IBM at the time but working for a small software developer company. I do remember, having a loan RT from IBM for porting our software and was impressed with the rugged machine. We weren't given... [More]
Hi, I am just back from the Prague Technical University last week. Everything worked well at the conference at the Hilton and the sessions were excellent - even the ones that I ran :-) but I keep making one mistake ... I volunteer to give an extra session or two. I ran the following sessions: Systems Director Lecture for AIX/POWER Users This covers the basics for a techie that needs to get it running including the architecture/components, pre-requisites, Advanced plug-in selection, The Systems Director Editions for reduced cost, compared...

This picture was taken by Shawn Mullen - Security Architect for AIX and cool speaker at the event too. It was taken outside of the Gala Dinner on the Wednesday evening - where we had good food and "interesting" Czech musical entertainment at the beautiful historic Zofin Palace on an island in the main river. From left to right are some of the top speakers at the conference: Ignoring the waiter with the excellent champagne!

Hot news this morning is IBM announcing the updating of the Lower End Power 710/730 and Power 720/740 models to include Power7+ processor with 2.5 larger L3 cache, Active Memory Expansion accelerator, and GHz boost Double the memory size This gives a large performance boost and drastically higher "bangs per buck" as the Americans say or "Value for money" as we Brits say. Almost everything else is the same so if you know the older models it is easy to understand Announcement letters for the new Power7+ models: Power 710 ,... [More]
I have long thought it is rather silly that IBM Systems Director can't give you a list the licenses that you should have! It does, after all, know what machines it is controlling and the data is in the database. Perhaps, that will come in the future. What can we do in the short term? Generally, I like to do everything from the graphical user interface (GUI) . I have not got time to learn and use both GUI and CLI. The system configuration data can be extracted using the command line interface (CLI) on the Systems Director server, so I spent... [More]

five years ago on January 21, 1986, IBM Austin launched a new operating system
called IBM RT Personal Computer A dvanced I nteractive e X ecutive
-- better known as AIX-- with a new system called the IBM RT
PC. The system ran on a RISC processor codenamed “ROMP” (for Research Office
Products Division MultiProcessor) and was originally marketed as an engineering
the RT was an unremarkable hardware platform it did represent the first time
that IBM really started to get serious about UNIX (AIX version 1 was... [More]
