Listener not being created

[premchand Singh]

hi i am trying to create new DB in oracle 10G , but while creating it i am getting the following error...

ORACLE- 12560:TNS: Protocol Adopter error...
i came to know there is need to create some listeners for this...so in "tnsnames.ora" under ADMIN i tried to configure it but i am getting how to do it...
the contains that is already here in the "tnsnames.ora" file is as follows:

# tnsnames.ora Network Configuration File: D:\oracle\product\10.2.0\db_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 129.221.10.78)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

EXTPROC_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
(CONNECT_DATA =
(SID = PLSExtProc)
(PRESENTATION = RO)
)
)

Someone please advice me how to configure the same...

Thanks in advance:

I am moving this to the oracle forum, where people should know much more about setting up an oracle database.
