Error:Network Adapter could not establish the connection
posted 4 years ago
I installed Oracle SQL Developer ,i am trying to create a new connection but i am getting this error message "The Network Adapter could not establish the connection".
The hostname is :localhost
Oracle is running ,i checked it in the task manager .I dont know what a tns file is .This is my first time installing or running oracle ,i just have a basic idea of some of the oracle commands.The oracle sql developer tool is opening when i run through command prompt .
