Data Source = LOCALHOST , User = SYSTEM , Password = xxxxx

its works fine in Computer A. Even i can connect it as
Data Source = 10.20.30.40 , User = SYSTEM , Password = xxxxx

How I can Connect from Computer B - to - Computer A ?

    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = XE)

EXTPROC_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC_FOR_XE))

    (CONNECT_DATA =
      (SID = PLSExtProc)
      (PRESENTATION = RO)
    )

ORACLR_CONNECTION_DATA =
  (DESCRIPTION =
    (ADDRESS_LIST =

Thanks for your support guys..

Now i'm clear with tnsnames.ora

my mistake is

XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = TOPAZ)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)

In XE datasource i need to give my current IP and configure it as
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 198.233.6.7)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)

If you want to check whether your Database is connected,
in cmdprompt
c:/>tnsping XE
it should reply
OK<;>
Then it means your connection is works fine...

Happy coding...

Cheers.,
Karthick

u can just specify the destination oracle db server name in any system which r in lan can connect to that db only

use oracleclient class to interact with oracle db
