UUID is a good old problem when it comes to running SAP NetWeaver on Linux / SuSE. You have a problem when you log in to your SAP system and get an error message. The error message shows the root cause and solution: “The UUID daemon (uuidd) is not active (code 59999). Check SAP note 1391070.”
Solution
SAP NetWeaver isn’t meant to run in Docker. When the software was designed, Docker or event containerization wasn’t around (maybe SUN). NetWeaver assumes that it is executed inside a real Linux. And the Docker version of OpenSuSE isn’t 100% a real Linux. A lot of services you get “automatically” when installing OpenSuSE are not available. One of those is that the init.d system is not starting services. Because of this, there is no UUID daemon running.
Make sure that the UUIDD service is running. For a normal Linux distribution, I blogged about this at a previous blog of mine. In case you are using Docker with OpenSuSE, make sure that uuidd is installed and executed during the image creation:
Installation
RUN zypper --non-interactive install --replacefiles uuidd
Execution
RUN mkdir /run/uuidd && chown uuidd /var/run/uuidd && /usr/sbin/uuidd
Result
With the UUIDD running, the logon to SAP NetWEeaver ABAP is working. No restart of NetWeaver is needed.
The difference is that in Gregor’s version you download the NW ABAP installation files and when the container is build, you go manually through the installation. My Dockerfile assumes that you have downloaded the NW 7.51 ABAP installation files already and will automate the installation. Once you have downloaded the installation files from SAP you can make them locally available and create new Docker images / containers based on these, without having to download almost 16 GB again. And the installation script will run without prompting for user input.
Another differentiation is that you can “easily” change the Dockerfile to install NetWeaver 7.50 of the developer edition.
Pre-requisites
To be able to run the Dockerfile, you need
Docker installed
Downloaded and extracted installation files of SAP NW ABAP Developer Edition
Internet connection
Installation
1 Get the Dockerfile
From my GitHub repository, you can find a Dockerfile that helps you to create a Docker image and container that will install your downloaded NetWeaver version. All you need is the Dockerfile, so a simple download is sufficient. You can also download the file by cloning the GitHub repository: https://github.com/tobiashofmann/sap-nw-abap-docker
Un-compress them into a folder named NW751. The folder must be at the same location where your Dockerfile is.
Build the Docker image
Build the Docker image
Command:
docker build -t nwabap .
Sample output
After the build is finished, the last line you should see is
Successfully tagged nwabap:latest
To see the ID and name of the newly created image, run the following command:
docker images
Sample output
The command lists the ID, tag and size of the image. As you can see, it’s a 15 GB Docker image. Using this image, you can start a container and install NW ABAP 7.51 DE inside the container.
Create container from image
You can now create a container from the image. You’ll have to connect to the container and run the installation script run.sh. The file was created during docker build. It will run SAP’s install.sh and fill in the input automatically.
docker run -P -h vhcalnplci --name nwabap751 -it nwabap:latest /bin/bash
This will start the container and log you in. What you’ll get is the bash shell.
bash-4.3#
In case you have Kitematic installed, you can see the running container listed.
The container configuration for the ports is also visible there. The ports are automatically mapped by Docker. The message server port 3200 is accessible through localhost:32771, and the HTTP port 8000 through localhost:32769. This mapping can be changed either inside Kitematic or when the container is started on the command shell.
Run ls to see the content of the current directory. You can see the install.sh file from SAP (feel free to start the installation manually) and the run.sh script that will automate the installation.
Start installation
Run the script run.sh to install SAP NetWeaver ABAP 7.51. The script will enter all information requested by install.sh automatically. The installation will take some time, +/- 20 minutes.
./run.sh
Sample output

The installation worked when the script ends and you can see the output:
After installing Personas 3.0 SP4, you have to do some additional tasks in your system to really enjoy the power of Personas 3.0. These steps are outlined in the release note 2376426, as well in the note 2383296 and 2376427. Both SAP Note are going to be uploaded manually to my NetWeaver system, as I do not have a connection to SAP. You can follow the steps my other blog on how to do this.
Check that Personas 3 add-on and is already installed. SP04 is a support package, therefore SPAM is used to install it. SP4 needs SPAM with patch 63 in NetWeaver 7.5. Ensure to update first your SPAM to the right version. See my other blog on how to update SPAM. Before you can update, check that there are not objects locked in a transport request.
Update
Transaction: SPAM
Client: 000
User: user with right permissions
Check that SPAM status is green and no queue is defined.
Upload SAR file: Support Package -> Load packages -> From Front End
Decompress.
Check the uploaded package. Select new support package under directory and then display.
The status needs to be yellow (not yet imported) and the perquisite set 01 all must be green and ok.
Select the package and click on Queue to define a new queue.
This SP04 is not protected with a password.
Select No. This brings you back to SPAM main screen. The status is now yellow and next action is given as import queue.
Import queue. Go to: Support Package -> Import queue.
You can now go get a coffee or follow the status messages in the status bar.
At the end of the import, a dialog is shown. It should be a nice “success!!” dialog, I got this:
What happened is that I applied a Personas 3 note that changed some standard objects. The dialog is SAP’s polite reminder to check if I want to keep these changes or discard them and let Personas 3 SP03 overwrite them. I want to not keep them and let Personas 3 use its own repository objects, so I selected continue. At the end you’ll see a short walk through what you should do (analyse the stuff, etc), although this isn’t possible in my demo system, as I do not have a SAP Note connection – something needed to run the validation.
