    documentation for ora-12505


    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.
    check if your parameters for

    Java Code:
    String url = "jdbc:oracle:thin:@" + serverName + ":" + portNumber
    					+ ":" + sid;
    			connection = DriverManager.getConnection(url, username, password);

    are ok. perhaps it helps: the default sid for oracle is ORCL and check if one listener is running.
