Listener refused connection with the following error ORA-12514

user5108636Dec 26 2017 — edited Dec 27 2017

Hi All,

I have setup a VM with Linux and Oracle Database. I am able to connect using SQLPlus locally to the database. However, when I try conecting from SQLDeveloper locally, I am getting this error message.

Listener refused the connection with the following error:ORA-12514. TNS Listener does not currently know of service requested in connect descriptor.

I tried suggestions from various forums and also tried tnsping <connect identifier>.

Still cannot figure what's going wrong with the connection. Please advise.

Thanks
