Can anyone please tell me method for checking oracle data base network status?
@Cybernate response is fairly easy from a command prompt:
For DB that is running
C:\Users\user_name\tnsping db_name_thats_running

Attempting to contact (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = ######)(PORT = 1521))) (CONNECT_DATA = (SERVICE_NAME = db_name_thats_running)))
OK (80 msec)
For db that is not running
C:\Users\user_name\tnsping db_name_thats_not_running

Alternatively you could just use sql*plus or any other program to try to connect.
