Mon, Mar 30th 2015 5:33p   Mikkel Heisterberg
First, thanks to Mikkel for letting me publish this on his blog. I've always gone back and forth about starting my own blog in the past, but never did, hence why I needed some help to get this message out. So, why am I writing? I'm excited to announce that I have accepted a new role within my current company, Gore. I will be transitioning into our customer facing capabilities center in Newark, Delaware. I will be championing the digital experience in that facility as well as helping the exis

Have VMWare ESXi VM hardware look like the underlying hardware
Mon, Mar 30th 2015 5:28p   Mikkel Heisterberg
Had an issue today where I couldn't use the IBM OEM Windows 2012R2 media that IBM provided together with our new xServer because the media running in the ESXi VM didn't see the underlying IBM hardware. The solution was to set an ESXi option on the VM called SMBIOS.reflectHost = "TRUE" as described in this post (Unable to install Microsoft Windows Server 2012 on VMware ESXi host - IBM System x). That made the VM represent the underlying hardware.

git log to the rescue
Tue, Mar 17th 2015 8:46a   Mikkel Heisterberg
Today I needed to figure out when a certain setting (DisablePrint - funnily enough disables print in the OnTime Group Calendar Notes UI's) was added to OnTime Group Calendar and I just couldn't remember. So how would I find out? No way was I going to do diffs all the way back through all my tags. A bit of googling and voila! - git log to the rescue. Using a combination of git log and git tag I was able to find out in a couple of minutes. Besides being very cool and an excellent display of the

IBM announce dates for bringing TLS v. 1.2 to IBM Domino
Mon, Mar 16th 2015 3:02a   Mikkel Heisterberg
So in October of 2014 I wrote about the upcoming TLS (transport layer security) enhancements that IBM was planning to bring to IBM Domino as part of the industry wide panic about the POODLE attack which I still consider mainly theoretical. I was a bit critical towards IBM as they chose to patch their seriously lacking SSL v. 1.3 implementation and implement TLS v. 1.0 on top of IBM Domino v. 9.0.x (IBM Domino, POODLE, SHA-1 and why it's also sad when IBM decides to update the security stack).

Docker without sudo
Sat, Mar 14th 2015 3:14p   Mikkel Heisterberg
Using Docker looks very promising but having to use sudo all the time is really a killer. Luckily there's a way around it by adding users to the docker group and restarting the docker service. Add the docker group if it doesn't already exist: sudo groupadd docker Add the connected user "${USER}" to the docker group. Change the user name to match your preferred user: sudo gpasswd -a ${USER} docker Restart the Docker daemon: sudo service docker restart If you are on Ubuntu 14.04 and up use do

Stumbled on this very nice easy way to export to a delimited file from the DB2 Command Line Prompt (CLI) today. db2 "EXPORT TO OF DEL MODIFIED BY NOCHARDEL " i.e. db2 "EXPORT TO result.csv OF DEL MODIFIED BY NOCHARDEL select * from empinst.employee"

Was looking through widgets-config.xml for IBM Connections v.5 to diagnose a customer issue and stumbled on the below widgetDef attribute. Now I haven't tried it yet but it looks like you can use it to hide a certain widget on your own profile e.g. only show when viewing other peoples profile. Could be useful. hideWidgetForMyProfile="true"

Atlassian SourceTree Pro-Tip
Wed, Nov 26th 2014 1:01p   Mikkel Heisterberg
I'm finding myself use Atlassian SourceTree more and more for my Git work as it's both intuitive, fast and very pleasing to the eye. Yesterday at an Atlassian event (Getting Git Right) I noticed that the branches were nested in one of the demos. I wondered how they did that but it turns out to be very simple. If you (re)name a branch and use slashes (/) in the name then SourceTree will automatically nest them. Very nice and does make it easier to distinguish between feature, release, bugfix br

Loading widget data in IBM Connections 5 by the aggregator
Wed, Nov 19th 2014 3:07a   Mikkel Heisterberg
One of the areas that changed fundamentally in IBM Connections 5 is how widget resources (JavaScript and CSS) is loaded by the browser. In prior versions the resources were loaded by the end-user browser through the AJAX proxy in IBM Connections Profiles or Communities depending on the feature in use. Starting with IBM Connections 5 the resources are aggregated and loaded by the Common feature that now also caches the resources. For end users this is great as speed and performance improves but f

An important tool results from the whole POODLE/SHA-2 debacle
Mon, Nov 10th 2014 1:41a   Mikkel Heisterberg
My stance on the POODLE / SHA-2 issues with Domino is well known and I haven't been holding anything back. And now - after a while - IBM is starting to release the promised tools to lay the foundation for SHA-2 signature support and TLS 1.0 support on IBM Domino. As part of my IBM Support Updates today I saw and entry called "Planned SHA-2 deliveries for IBM Domino 9.x". This is a technote outlining how IBM is bringing TLS 1.0 and SHA-2 support. This is all well and good and great that IBM st

IBM Domino, POODLE, SHA-1 and why it's also sad when IBM decides to update the security stack
Mon, Oct 27th 2014 2:00a   Mikkel Heisterberg
Over the last few weeks the news hit about the PODDLE attack and the withdrawal of SHA-1 as an acceptable hash algorithm by Google Chrome. This is turn has prompted IBM to update the security stack in IBM Domino for all web protocols incl HTTP, LDAP and SMTP. While this is VERY good news and it will be very welcomed that we do no longer have to resort to fronting IBM Domino by IBM HTTP Server or Apache to get adequate TLS protocol support I find the whole situation a bit sad.

Mac Yosemite, Java, IBM Notes and OnTime Group Calendar
Fri, Oct 17th 2014 1:51a   Mikkel Heisterberg
After upgrading my Mac to OS X Yosemite (10.10) I had to reinstall Java to make IBM Notes startup just like Rene describes. To install go to the download page for Java on apple.com, download and install. It takes around 5 minutes and you are ready to go. Once installed the Java runtime makes IBM Notes fly again and I can confirm that the OnTime Group Calendar UI's run just fine on OS X Yosemite.

In case you haven't heard about WebSphere Application Server Liberty Profile and you are doing any work with J(2)EE servers you really should do your self the favour and read up on it. In essence it's the best thing since sliced bread for application developers that target WebSphere Application Server and here's why: It downloads and installs in less that 5 minutes It's binary compatible with the full WebSphere Application Server so you can be certain that code that runs on Liberty Profile

Premaster RSA secret error with 4096-bit encryption in WAS ISC
Sun, Jun 15th 2014 11:40p   Mikkel Heisterberg
Had a customer the other day that couldn't import their SSL certificate into the WebSphere Application Server (WAS) Integrated Solutions Console (ISC) due to a "RSA premaster secret" error being shown when attempting the import. A PMR with IBM Support confirmed my suspicion that export restrictions was in play. Here is the response from IBM Support. The premaster RSA secret error with 4096-bit encryption is usually due to the unrestricted JCE policy requirement. Please, try to install the

Fixing an IBM Connections Social Mail CPU spike problem
Wed, May 7th 2014 12:28a   Mikkel Heisterberg
The other day we did a test upgrade of our internal IBM Connections 4.5 environment from CR3 to CR4 before doing the real upgrade. After the upgrade the CPU of the WebSphere Application Server node (we are in a single node architecture) would spike to a 100%. After some digging and perusing of log files we narrowed the problem down to IBM Social Mail and that component being loaded. Actually even more specifically to the Discovery Servlet which is used to discover the mail service for a particul

It's been a while!

Wow! Blogging hasn't really been my thing for a while. Actually I realize that I've flow a bit below the radar for the last couple of months. November saw the birth of our second child (a son, Matheo) and we're still adjusting a bit to the life as a two-kids family though it's getting easier. I sure enjoyed going to Summer Time this year as it means that he wakes up at 6am instead of 5am. Besides that 2013 ended in work, work and preparations for Connect 2014.
