Installing SAP HANA, express edition Server + Apps, with Docker

Download and install Docker Enterprise Edition for SUSE Enterprise Linux Server. Visit the Docker Enterprise Edition SUSE Enterprise Linux Server page for information on how to install Docker on your SLES system.

Note:
Ensure your proxy settings have been properly set up. See HTTP/HTTPS proxy in the Docker documentation.

If your host file system is xfs, you can recommend the storage driver through the devicemapper in Docker. Add -s devicemapper to the DOCKER_OPTS property in the docker file.

The minimum recommended storage size is 50G. For example:

DOCKER_OPTS="-s devicemapper --storage-opt dm.basesize=50G"

For Ubuntu and Debian, the DOCKER_OPTS property can be found at /etc/default/docker.

For Fedora, SuSE, and Centos, the DOCKER_OPTS property can be found at /etc/sysconfig/docker.

Restart the Docker service.

For example, on SuSE:

sudo systemctl restart docker.service

For more information on the storage driver, visit the Docker storage drivers documentation page.

To log into your Docker account, run:

sudo docker login

Follow the prompts and provide your Docker ID and password.

Test your Docker installation by running the “Hello World” container application. Run the following command from your Docker-enabled command prompt:

sudo docker run --name helloWorld alpine echo hello

If successful, the following should display:

Unable to find image 'alpine:latest' locally
latest: Pulling from library/alpine
88286f41530e: Pull complete
Digest: sha256:<log_number>
Status: Downloaded newer image for alpine:latest
hello

If hello is printed, you have successfully pulled the container image alpine (a demo Linux distribution), and ran the instance of the container helloWorld, and ran the command echo with an input parameter of hello.

If you did not get this output, the Docker installation has not been completed or the Docker daemon can not connect to the internet. Review the process and check the Docker Documentation for more information in troubleshooting your Docker installation.

Remove the alpine image with the following command:

sudo docker image rm alpine -f

Go to the Docker Store.

Click on the search bar and search for “SAP HANA, express edition”.

Choose SAP HANA, express edition (database and application services).

Click on the Setup Instructions button.

Copy the Docker pull address. Here is an example:

sudo docker pull store/saplabs/hanaexpressxsa:2.00.030.00.20180403.2

Open your Docker-enabled command line and use the Docker pull address to download the image.

This loads the SAP HANA, express edition image. To ensure that the image was loaded successfully, run:

sudo docker images

The SAP HANA, express edition image will be listed as hanaexpressxsa.

Note:
You may have to log into your Docker account to pull the image. From your Docker-enabled command line, run docker login and follow the prompts to enter your Docker ID and password. Once you have logged in, try the pull command again.

Before you can start the container, ensure that the following parameters are set in your host’s /etc/sysctl.conf file. The host can be a virtual machine, physical machine, or a cloud instance.

fs.file-max=20000000
fs.aio-max-nr=262144
vm.memory_failure_early_kill=1
vm.max_map_count=135217728
net.ipv4.ip_local_port_range=40000 60999

To edit the sysctl.conf file, use the vi command to open the file and press i to switch to interactive mode. Edit the file as necessary, hit the esc key, and type and enter :wq! to write and save the changes.

Load the changes by running:

sudo /sbin/sysctl -p

The hxehost IP address is private to the installation. In order for applications to access hxehost, add the hxehost IP address to your machine’s hostname map. The hostname map is your machine’s /etc/hosts file. You must edit /etc/hosts if you want to access any XS Advanced applications or use HANA Cockpit from your machine.

Use the following command:

sudo sh - c 'echo <hxehost_IP_address>    hxehost >> /etc/hosts'

To make your system more secure, you specify your own password before you create your container. This is done by creating a json file as opposed to having a default password. The file can be stored locally or on another system accessible by URL. If the file is to be stored locally, store it in the /data/ directory you created earlier.

Create the json file:

vi <file_name>.json

Press i to start editing and use one of the following formats to create the file:

{
"master_password" : "<password>"
}  

or:

{
"system_user_password" : "<password",
"default_tenant_system_user_password" : "<second_password>"
}

Here is an example:

{
  "master_password" : "SAPhxe123"
}

Press esc and then enter wq! to write and save the file.

This file serves as the master password for your SAP HANA, express edition users. The password must comply with these rules:

• At least 8 characters
• At least 1 uppercase letter
• At least 1 lowercase letter
• At least 1 number
• Can contain special characters, but not ` (backtick), $ (dollar sign), \ (backslash), ' (single quote), or " (double quotation marks).
• Cannot contain dictionary words
• Cannot contain simplistic or systemic values, like strings in ascending or descending numerical or alphabetical order

You must then add permissions for this file to be readable by the hxeadm user in the container. Change permissions with:

sudo chmod 600 /data/<directory_name>/<file_name>.json
sudo chown 12000:79 /data/<directory_name>/<file_name>.json

Be sure to do this with each json file you use for your Docker containers.

Make a note of the path to the json file. You will need this to load the SAP HANA, express edition container.

Use the SAP HANA, express edition image to create a container.

sudo docker run -p 39013:39013 -p 39015:39015 -p 39041-39045:39041-39045 -p 1128-1129:1128-1129 -p 59013-59014:59013-59014  -p 39030-39033:39030-39033 -p 51000-51060:51000-51060  -p 53075:53075  \

--sysctl kernel.shmmax=1073741824 \
--sysctl net.ipv4.ip_local_port_range='40000 60999' \
--sysctl kernel.shmmni=524288 \
--sysctl kernel.shmall=8388608 \

--proxy-host <proxy_hostname> \
--proxy-port <proxy_port> \
--no-proxy <no_proxy>

Example:

sudo docker run -p 39013:39013 -p 39015:39015 -p 39041-39045:39041-39045 -p 1128-1129:1128-1129 -p 59013-59014:59013-59014  -p 39030-39033:39030-39033 -p 51000-51060:51000-51060  -p 53075:53075  \
-v /data/express_edition:/hana/mounts \
--ulimit nofile=1048576:1048576 \

--agree-to-sap-license \
--passwords-url file:///hana/password.json \
--proxy-host <proxy_hostname> \
--proxy-port <proxy_port> \
--no-proxy <no_proxy>

This example creates the SAP HANA, express edition container with the name express_edition. This process will take several minutes. The prompt will read Startup finished once the container has been successfully running. This container starts in detached mode so you will need to open another command prompt to continue.

Note:
If you placed the password file in /data/<directory_name>/<file_name>.json, substitute file://<path_to_json_file> with file:///hana/mounts/<file_name>.json.

Note:
Check if the password file /hana/mounts/<file_name>.json was deleted after the SAP HANA, express edition container starts. If not, you can manually delete it. If the JSON file you are using is an http or https URL, you can leave out the -v option.

Note:
Ignore --proxy-host, --proxy-port, --no-proxy if you do not have a proxy server.

Note:
For Linux kernel versions earlier than 4, omit the net.ipv4.ip_local_port_range option.

To start your SAP HANA, express edition container, run the following command:

sudo docker exec -it <container_name> bash

Example:

sudo docker exec -it express_edition bash

When you are logged into the SAP HANA, express edition container, you can test your installation by entering the following:

whoami

You should be logged in as hxeadm, the default SAP HANA, express edition user.

You can also enter the following:

HDB info

And you should see the following services running:

• hdbnameserver
• hdbcompileserver
• hdbdiserver
• hdbwebdispatcher

You can log into the system database with the following command:

hdbsql -i 90 -d <system_database> -u SYSTEM -p <password>

You can log into your tenant database with the following command:

hdbsql -i 90 -d <tenant_database> -u SYSTEM -p <password>

JDBC

To log into your system database via JDBC, use the following command:

jdbc:sap://<ip_address>:39013/databaseName=<database_name>

To log into your tenant database via JDBC, use the following command:

jdbc:sap://<ip_address>:39015/databaseName=<tenant_name>

After you have logged in, view the list of XSA applications. Enter:

xs apps

Note:
When you run the xs apps command for the first time, it may take 1-2 minutes for the system to return the list of XSA applications.

Check that the application webide shows STARTED in the list of XSA applications, and has 1/1 instances. (If the list shows 0/1 in the instance column, the application is not started.)

Note:
Normally it only takes a few minutes for XSA services to start. However. depending on your machine, it can take over 30 minutes for XSA services to begin. If the service doesn’t show STARTED and doesn’t show 1/1 instances, keep waiting until the service is enabled.

Make a note of the URL for webide.

Note:
The command xs apps | grep webide returns the webide row only.

Test your Web IDE connection. Enter the URL for Web IDE in a web browser.

Example: https://hxehost:53075

Log on to Web IDE using the XSA_DEV user and the password you made during installation.

If you are prompted to change your password, follow the instructions.
