    why can I log in using sql plus but not sql developer


      I am new to all of this and I am trying to use sql developer but I am not able to set up a connection. I am wondering if it is a problem with the hostname. my hostname is ol6-121.localdomain and not localhost. Why am I able to log in with sql plus but not sql developer? I am using the oracle VM virtualBox. I am using the practice hr schema.



      Figured out the problem had to change the MAC address to 080027F5C0DA in the network setting in the VirtualBox.
