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. Use the OS X hosts version.
Double click on OS X hosts version. Allow the download, if prompted.
A dmg file referred as VirtualBox and the version can be found in Downloads (see example below for version 6.1.8). Double-click on the file to install VirtualBox.

A verifying process may occur before this screen is shown. Follow the two steps stated in the install program.

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.

Select the download button and click download anyway.

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 import. You just need to follow a series of steps.

When you are finished, the VirtualBox main interface should show the two Opal servers.

Configure the network

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.

You can also click on the Machine menu and the Settings option.

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 Tools, and a new window will pop up.

In the window, click on the create icon.
- Ensure Configure Adapter Manually is checked for vboxnet0
  - IPv4 address: 192.168.56.1
  - IPv4 Network Mask: 255.255.255.0
- Ensure Configure Adapter Manually is checked for vboxnet1
  - IPv4 address: 192.168.57.1
  - IPv4 Network Mask: 255.255.255.0

At the end of this process there should be two items with the name "vboxnet0" and "vboxnet1".

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). Click on Normal Start. If your security settings is preventing it starting the virtual machine, then click on Headless 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.

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

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.
