WebLogic Datasource: ServiceName vs SID

if your DB is setup to use a Service Name rather than a SID, the URL syntax is slightly different:


jdbc:oracle:thin:@1.2.3.4:1521/SERVICENAME

instead of the usual

jdbc:oracle:thin:@1.2.3.4:1521:SERVICENAME


If you make a mistake, you will get the dreaded

Connection test failed.
Message icon - Error Listener refused the connection with the following error: ORA-12505, TNS:listener does not currently know of SID given in connect descriptor
