Dear Al,
I found one issue at tns entry of database/ When I use host name as ip address, it gives error. When I use host name as server name, it proceeded without error. Below is the error and tns entry at database. But what ever use in host name at client side, it gives same error.
May be it would help you to assist me to rectify the problem..

Dear BlackSwan,
There is only one oracle home 2 databases at server.
I have installed 10g client again to check, whether same problem is persisting or not? Still, the same error persist.
Below is the path-
C:\Users\Administrator>path
PATH=D:\oracle\product\10.2.0\client_1\bin;F:\app\Administrator\product\11.2.0\dbhome_1\bin;C:\Windows\system32;C:\Windows;C:\Windows\System
32\Wbem;C:\Windows\System32\WindowsPowerShell\v1.0\;C:\Windows\System32\Windows System Resource Manager\bin;;C:\Windows\idmu\common
Request you to elaborate your view. May be your valuable inputs may come out with great results.
Regards,
Ashish Kumar Mahanta

Dear Michel,
It is happening for only one database. Because, client is able to connect to other database with ip address.

Tns-entry at both database & client is same -
UICUINTG =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.140.128)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = UICUINTG)
)
)
Parallely, I am taking help of network team to find out the conflict of ip address and host name.
Regards,
Ashish
