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.
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.
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.
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.
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…
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.
* 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.
By default, remote desktop connections on windows use port 3389. If you find the need to change this port, the following should help. Make sure you have “Allow remote connections to this computer” checked under “System Properties > Remote” before you begin.
