Can you show how you are creating the database? – Rahul Tripathi
check this stackoverflow.com/questions/18192521/… and this docs.oracle.com/cd/B19306_01/server.102/b14219/net12500.htm – Moudiz
have you taken a look at docs.oracle.com/cd/B19306_01/server.102/b14219/net12500.htm ? go to 12505 and try what it says there – Jeremy C.

try this. source from docs.oracle

ORA-12505: TNS:listener does not currently know of SID given in connect descriptor
 Cause: 
The listener received a request to establish a connection to a database or other service. The connect descriptor received by the listener specified a SID for an instance (usually a database instance) that either has not yet dynamically registered with the listener or has not been statically configured for the listener. This may be a temporary condition such as after the listener has started, but before the database instance has registered with the listener.
Action: 
- Wait a moment and try to connect a second time.

- Check which instances are currently known by the listener by executing: lsnrctl services <listener name>

- Check that the SID parameter in the connect descriptor specifies an instance known by the listener.

- Check for an event in the listener.log file.
