Oracle database connection

Any idea when the Preview will have the capability to refresh via Oracle ?

Oracle: ORA-12154: TNS:could not resolve the connect identifier specified

getting error while connecting to oracle database in BI desktop

In using the Database connection method, I have connected to Oracle database dbABC on a server dbsServer using specific credentials for dbABC. Now I want to connect to Oracle database dbDEF on the same server (dbsServer) using specific credentials for dbDEF. Power BI seems to default my second connection with the credentials for dbABC, so I can't see the tables in dbDEF. Is there a way to enter my new credentials to connect to dbDEF so I can see the appropriate tables?

Does PowerBI really connect to Oracle Database ? i have been getting this error message for a while now: Oracle: ORA-12154: TNS:could not resolve the connect identifier specified
