ORA-12514 TNS listener does not currently know of service requested in connect descriptor

user5108636Feb 5 2026

Hi All,

    I am using the Oracle APEX image on Virtualbox. Everything was working until the virtualbox has been restarted.

I am not sure, but looks like the database has not come back properly I believe.

When I use the SQLDeveloper to connect to the database, I get the ORA-12514 TNS listener does not currently know of service requested in connect descriptor error.

What should I do to verify the possible issues. Believe the database is not running. Please advise
