my tnsnames.ora entry is

newDB = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.46)(PORT = 1521)))(CONNECT_DATA = (SID = newDB)(SERVER = DEDICATED)))

when started the listener, iam getting the message
The listener supports no services

I guess this is the root cause of the error.

Is anything wrong with my listener.ora and tnsnames.ora ?
