This means you ought to have a began and completely functional oracle database instance in your machine.

Are you able to see following services running inside your virtual machine. run services.msc

  • OracleXE
  • OracleXEListener

If they're began and you will connect Oracle XE inside your virtual machine (Use XE's connect to start menu link for simple checking. )

Your issue is together with your network reference to VM as well as your Host machine. Turn to coworker's network connection configurations. Virtual Box version is below.


  • Not attached
  • Network Address Translation (NAT)
  • Bridged networking
  • Internal networking
  • Host-only networking
  • Generic networking

After you accomplish that , you have to improve your connection string if you're attempting to connect from Host to Virtual Machine. Give your Virtual Machine's IP inside your connection string.
