DataSHIELD support is freely available in the DataSHIELD forum by the DataSHIELD community. Please use this as the first port of call for any problems you may be having, it is monitored closely for new threads.

The minimum computer specification for installing the DataSHIELD training environment is:

Ideally 12GB+ of RAM. Each VM is allocated 4GB RAM, and some needs to be spare for other applications.
Reasonably powerful processor (for example: Intel i5 or i7).
16GB space on the hard disk.
- 7GB per VM + VirtualBox installation requirement (215 MB)
Administrator rights on the computer. If you do not have administrator rights to install software on your computer contact your IT support to get the following installed on your machine.

Download and install VirtualBox

Download VirtualBox from here.
Double click on the downloaded executable file and click Next and Yes to install the default settings.

Download and install the Opal tutorial servers

Download the Opal servers (synthetic data are included)

These Opal servers are 1-2 GB in size and may take some time to download.

Right click and open each of the Opal tutorial servers in a new window.

Download Training VMs

dstutorial-100 (Opal Server 1)

dstutorial-101 (Opal Server 2)

Select the download button and click download anyway.

You may see a network error warning, this is because the file is too big to preview in Google Drive. To continue, press the downloadbutton.

Import the Opal tutorial servers into VirtualBox

To install each Opal tutorial server, select File from the top menu and then Import Appliance..., browse to each downloaded tutorial file and install.
When you are finished, the VirtualBox main interface should show the two Opal servers.

Configure the network

Importing the Opal servers should create the correct settings, however please check your settings match those below.

Setting up the VirtualBox network adapter

Select one of the Virtual Machines (VMs) and click on the orange cog settings on the top bar, right hand portion of the screen.

Inside that window and under the tab Network, ensure that
- Under Adapter 1, Enable Network Adapter is checked and it is Attached to: NAT.
- Under Adapter 2, Enable Network Adapter is checked and it is Attached to: Host-only Adapter.

Repeat this for the other VM by first selecting it on the list.

Next we need to ensure DHCP server is not enabled.
Click on File,... Host Network Manager, and a new window will pop up.

In the window, there should be one item with the name "Virtualbox Host-Only Ethernet Adapter"

In the furthest righthand column is the "DHCP Server". This should be unchecked- not enabled.
Next, rightclick on the name "Virtualbox Host-Only Ethernet Adapter", and select Properties.

This will give an options bar at the bottom of this window.

Ensure Configure Adapter Manually is checked and
- IPv4 address: 192.168.56.1
- IPv4 Network Mask: 255.255.255.0

Starting the Opal Servers

Start the Opal Servers

To start an Opal server, open VirtualBox ,click on a server and click on the green arrow that says Start (or just double click on the Opal server name).

Depending on how powerful your computer is, the Opal servers may take a few minutes to boot and for Opal to start.

If you are presented with more than one Operating System in the black 'Oracle VM VirtualBox' window select the first option by pressing enter on your keyboard.

Be aware, once the VM windows have started, clicking inside them can cause your mouse pointer to become captured. The default key to escape this is Right-Ctrl

The Opal web interface

This is a simple check to tell if the VMs have started.
By going to the Opal web interface by opening a web browser and typing the IP address of each:
- http://192.168.56.100:8080
  http://192.168.56.101:8080

Because these VMs are internal to your computer, there is no need for encryption, so port :8080 is safe. In addition you should be able to login to the local servers even if you have no internet access.

Trouble logging into Opal web interface

Try using port 8443 > https:/192.168.56.100:8443 and https:/192.168.56.101:8443 .You will get a warning when connecting to 8443 because the SSL certificate is self-signed.

Opal is running and ready if the opal login screen is available. You do not need to login; just check that a login webpage is available.

If at this point your Opal server(s) are not working, right click on an Opal server name and select Settings. Select System and enable I/O APICand disable Hardware Clock in UTC time. Restart the Opal servers

Should you require logging into the Opal web interface e.g. to upload your own data etc:
