Please note that the Oracle VirtualBox machines are for testing and education purposes only, as such are unsupported and should not to be used in production environment. The machines contain no firewall and selinux has been disabled.

Memory

Each virtual machine is configured by default with 2.3 Gb of memory, which is the minimum required. 

...

Note that the maximum amount of memory that an Oracle XE 11g database uses cannot exceed 1 Gb, even if more is available. The other memory is configured for non-Oracle operating system processes.

CPU

Most modern computers, even laptops, have multi-core CPUs. Each virtual machine is configured by default with 2 virtual CPUs. Oracle XE 11g will consume, at most, the processing resources equivalent to one CPU. The other CPU is configured for other, non-Oracle operating system processes.

Disk

Each machine has one 30 Gb disk. The disk is configured as a dynamic VirtualBox disk and only consumes the space required by it's contents. The initial contents of the disks take up about 12 Gb of space but the disk can grow up to 30 Gb if required.

Audio

No audio device has been configured for the virtual machines.

Network Adapters

Each virtual machine has a single Host-only network adapter configured on the default Host-only network of 192.168.56.0/24.

...

Tip

The Host-only network will enable you to use client tools on your host machine to connect to the databases on the virtual machines. So you can use tools like SQL*Developer or TOAD etc on your host.

 

Serial Ports

No serial ports have been configured for the virtual machines.

USB Ports

Each machine has been configured with 1.0 USB controller although this is not used as part of the Rep Attack. A USB 2.0 controller has not been configured as this requires the installation of the Oracle specific extensions to VirtualBox.

Shared Folders

A common shared folder has been configured on each virtual machine. These are used to transfer files to and from the virtual machines from the host. 

...

Tip

The virtual machines are not connected to the internet so if you want to download something, use the internet connection on the host and place the file in the shared directory.

Snapshots

The virtual machines execute from an 'Initial" snapshot that allows you to restore the machines back to their original starting position.
