ORA-12528 TNS Listner When I try to connect the database using sql developer it gives the error below:

ORA-12505 TNS:listner does not currently know of SID given in connect descriptor

I have tried all the suggestions that I found on this website, but in vain, they are not working. 

I checked the instance and database status, they are started and active. But why I still can not connect to that?

When I try the oracle - default database, that is ok, but I want to connect to my own database, So can you help me to solve that problem?
This means the that the listener is up and running, but the SID or SERVICE_NAME in the CONNECT_DATA section of your net service connect descriptor does not specify a SID or SERVICE_NAME that the listener is aware of.  The listener does not know where to send your connection.

See the full text of the error message:

$oerr ora 12505
12505, 00000, "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 &lt;listener name&gt;
//  - 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.


Hope that helps.
