Installing SAS Viya 4 (2021.1.2) Locally

I have been wanting to get SAS® Viya 4 running locally on our lab hardware to further investigate the REST APIs, and having just finished the installation, I thought I’d jot down a few notes.

SAS Viya 4 has initially been released for the main cloud providers: Microsoft Azure (AKS) first, and now Amazon (EKS) and Google (GKE) too. I understand that RedHat OpenShift support will be coming later this year.

I’d heard it was also possible to get it running in a local on-premise Kubernetes (K8s) environment with some prep work Continue reading “Installing SAS Viya 4 (2021.1.2) Locally”

Java Look & Feel with SAS Management Console on Linux

As someone who specialises in SAS® metadata security, I spend a lot of time using the Authorization tab in SAS Management Console. I also use Linux a great deal. When I run SAS Management Console on Linux, I’ve noticed that the check box background colours on the Authorization tab don’t render correctly (for me at least). I only ever see white background check boxes when I expect to also see green and gray ones: green indicating an ACT; white indicating an ACE; and gray indicating indirect. These colours are important indicators for the source of access controls so not being able to see them is a problem!

It occurred to me that I might be able to resolve this by specifying a Java System Property in the sasmc.ini file to change the Java Look & Feel.

I first tried changing the default look & feel (using ‑Dswing.defaultlaf) but that didn’t work. What did work is changing the default system look & feel (with ‑Dswing.systemlaf). Continue reading “Java Look & Feel with SAS Management Console on Linux”

Auto Creation of Linux Home Directories for SAS Users

In a previous post I’ve described a method for configuring Active Directory Authentication for SAS® on Linux (with realmd). One of the packages that’s installed is oddjob-mkhomedir. This package normally handles any requirement for auto-creating home directories for those AD users on Linux. Unfortunately it doesn’t seem to get used by the SAS Object Spawner. I ran into this issue again today when logging into SAS Studio 4.2 as an AD user on the SAS Viya™ 3.2 platform. I wasn’t able to login because the AD user’s Linux home directory didn’t exist and hadn’t been auto created. After manually creating the home directory the login succeeded. I would rather get auto-creation working so I wouldn’t need to manually create home directories for each SAS user that was likely to use SAS Studio. Thankfully I was able to find a solution that I’ll describe in this post. Continue reading “Auto Creation of Linux Home Directories for SAS Users”

Active Directory Authentication for SAS on Linux (with realmd)

This is another post in the series about configuring a SAS platform on Linux to use Integrated Windows Authentication (IWA), in this post I’m going to jot down some notes on steps 1-7 – configuring the Linux server for Active Directory (AD) Authentication.

Some time has passed since I wrote the original post, and a few things have changed. I’m now running SAS 9.4 M3, but this post should equally apply to SAS 9.4 M2. I have also switched the Linux distribution from Debian to CentOS 7.1. I am also using a much simpler method of joining the Linux server to the AD domain, using the realmd package (previously there were lots of individual steps using the underlying packages but realmd automates most of this). In this post I’m going to outline the simpler method using realmd of course.

Here goes … Continue reading “Active Directory Authentication for SAS on Linux (with realmd)”

SAS Download Manager in Console Mode

SAS® 9.4 M3 is now available (as discussed by Andy Ratcliffe in his recent NOTE: blog post), so I’m downloading a new SAS depot using the SAS Download Manager. I’m downloading it onto a Linux server that happens to have X11 available, but I’m choosing to use console (text) mode, rather than the default X11 windowed mode.

Using SAS Download Manager in console mode is my preferred method because I find it more flexible. Why Console mode? I know from experience that a SAS depot download is going to take a few hours and, if I run SAS Download Manager in windowed mode, I risk losing the remote X connection if there are any network disruptions between me and the server. By running SAS Download Manager in console mode, in combination with screen over an SSH session, I can easily disconnect/reconnect as required. I can disconnect (Control-A D) when I leave the office to go home, and reconnect (screen -r) when I get home to check on progress. I can also get screen to capture a log of the session in a text file (screen -L).

Of course, I could have used a Windows or Mac version of the SAS Download Manager to download onto a laptop and then upload onto the server, but that ties the laptop to a single location for the duration of the download. Plus if I’m not near the server at the time, I’d have to download and then upload nearly 50GB of SAS depot. If I’m traveling with my 4G mobile broadband connection, the server also has a much faster and much cheaper internet connection than I do! These are some of the reasons I prefer console mode.
