Question

Is there any function in oracle database to provide the current connected server name (or ip) on which the database is running?

The question in other way,
in oracle tnsnames.ora file I have the following

ORA9 =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.14.208)(PORT = 1521))
      (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.14.209)(PORT = 1521))
    )
    (CONNECT_DATA =
      (SERVICE_NAME = orcl)
    )
  )

How to know if the connected server ip is 192.168.14.208 or 192.168.14.209 in my application?
