Sorting Alternative Dimensions and Measures in Qlik Sense

Alternative Dimensions and Measures have been in Qlik Sense since version 2.2 (see a video on Qlik’s site describing how to use them) – but there isn’t yet an easy way to sort them (as of version 3.2.2).


This bar chart object has multiple alternative dimensions and measures (note the arrows next the the axis titles)


When configuring charts with alternative dims and measures you’ll find you can only configure the sort order for the currently active dimensions and measures – nothing else will be visible or configurable.

Integrating QlikView into SalesForce SFDC with SSO – forcing TLS1.1 or higher

Integrating some QlikView screens into Salesforce, and using Salesforce to authenticate your users is actually very simple. Joe Bickley from Qlik wrote about setting up Salesforce SSO back in 2012 – and I thought I’d have a go.

The only road block encountered along the way was Salesforce’s decision to disable TLS 1.0. They have a number of very good reasons, including the famous Poodle vulnerability. It meant I experienced the error below:

UNSUPPORTED_CLIENT: TLS 1.0 has been disabled in this organization. Please use TLS 1.1 or higher when connecting to Salesforce using https.


AppExchangeAPI.GetUserInfoResult userInfoResult = binding.getUserInfo();

This isn’t yet a mandatory change for production organisations, but it will be by 22/07/2017. Any development organisation will have it enabled by default, without any method for disabling. Other services do not have a disable date at the time of writing this post.

Uh oh, things aren’t well with SFDCLogin.aspx

Setting up a CentOS 7 local development VM with LAMP (Linux, Apache, MariaDB/MySQL, PHP+PHPMyAdmin)

I’m going to build a local VM with the following requirements:
1) It can host PHP/SQL-based websites
2) It has PHPMyAdmin to help administer any SQL databases
3) It matches available builds from popular providers (i.e. you can provision it in a similar way on Azure or AWS, but with a public domain name)
4) It only has a single account (this is not recommended for public systems)
5) I can access the web root using SFTP

As I already have several CentOS builds that have always been pre-setup with CPanel (and because CentOS is free), I’ve decided to do this build from scratch and without a control panel. I’m not going to be configuring options like multiple user accounts, so things will be fairly simple.

I’ll do it in steps (and test each time) to make sure everything’s working correctly. You could install everything all at once, but that would make it much harder to troubleshoot if an element didn’t work.

Installing a SSL certificate to Qlik Sense Enterprise on Windows Server 2012 R2

Updated on 22/12/2017 to add two other ways of generating a CSR (see below).

In this post I’m going to look at how quick and easy (and cheap) it is to procure and install a SSL certificate on your Qlik Sense deployment. This assumes you are starting with only the self signed certificates, and that you want to use a certificate generated by a signing authority for use on an externally facing site.

A couple of things to note:

  • I’m using Qlik Sense Enterprise 3.1 with a single-node deployment using the default settings
  • You have a choice of verification methods – I chose to use DNS by adding a CNAME (pointer) to my chosen domain, and managed this through a linux DNS host. You can also verify through email or http (placement of a file)
  • I’ve used a basic certificate from PositiveSSL that offers only domain validation (DV). Certificates offering greater levels of protection and assurance are also available
  • The server is running Windows Server 2012 R2 with IIS 8, which is up-to-date with the latest updates at time of writing (January 2017)


On a clean installation of Qlik Sense Enterprise, you’ll note that the domain fails SSL validation in most browsers. Why? Because the certificate is one that has been generated by your server, and not by a “trusted” certificate authority. Have a read of this page about Certificate Authorities if you’re after further detail.

What is Big Data? Thinking about a definition suitable for me

I recently worked on an app that was loading from several hundred gigabytes of CSVs, and attempting to perform expensive transformations on these files in Qlik Sense. Normally this isn’t a problem, but due to the way the transformation was written, the result was a saturated server…and I found myself reflecting what “Big Data” means to different people (and to myself).

A recruiter’s post on LinkedIn also made me chuckle, as it highlights the disparity between definitions well. From my view of big data, I doubt that someone working in that field is likely to be interested in a role where one of the three core job skills is Excel…


Strong in Data Manipulation/Excel/Big Data – so which is it?


My observation is that there are two camps – one side that classifies using the “V’s”, and another using an altogether simpler definition! Continue reading “What is Big Data? Thinking about a definition suitable for me”

CentOS 7 Linux Minimal Install – ifconfig: command not found (let’s use ip instead)

As someone who doesn’t closely follow what’s happening with Linux tools, I recently tried a minimal CentOS 7 install, and found out by chance that a command I use a lot on Windows has been deprecated in a number of Linux releases.

Not having run into this before, my first thought was to see if it was in the core repos.

yum provides ifconfig

ifconfig is part of the net-tools package

SEATT updated to 1.4.0

I’ve updated Simple Event Attendance (SEATT WordPress plugin) to version 1.4.0. This brings bug fixes, and updates in line with the release of WordPress 4.5.3, as well as the upcoming 4.6.0 release.

The plugin can now also be found on GitHub: to help you track changes if you’ve made any modifications yourself.

This covered some of the feature requests at, as well as fixes for get_currentuserinfo in WP 4.5:

* Replaced get_currentuserinfo with wp_get_current_user to fix deprecation issue
* Fixed bug where users couldn’t register to an event with limit set to 0 (unlimited)
* Fixed bug where server time was used rather than blog local time on front end form
* Updated admin and template to allow use of TinyMCE for WYSIWYG editor. Can now also add images, colours etc.

Qlik Sense and general port troubleshooting on Windows Server 2012 R2

One of the beauties of Qlik Sense Enterprise is that it can be installed on nearly any Windows machine, with very few pre-requisites.

One of the drawbacks is that you may then be tempted to load it onto a multi-purpose box, or at the very least, one with a number of core Windows roles installed (especially if you’re just testing).

Uh oh, it's a 404
Uh oh, it’s a 404

This post is going to offer some quick ways of resolving port clashes, and working out what’s binding where without changing the core Qlik Sense Enterprise installation.
