recreate listener.ora

Hi Friends,

I accidentally deleted my listener.ora , how do I rebuild it?

I tried copying from other running listener.ora from other server and
edit the necessary path/dir,sid,host,etc like this below:

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

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(SID_NAME = hsodbc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = hsodbc)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(SID_NAME = orcl)
)
)

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.0.56)(PORT = 1521))
)
)

But i got error TNS-01150 : The address specified LISTENER name is incorrect

Pls help....

Thanks a lot

Don't you have a backup of your filesystems?

What about just running netmgr and setting the listener up again?

The easiest is to from $ORACLE_HOME/bin enter:
./netca
that will guide you through.
If you are running windows go to Programs -> oracle -> configuration.
One of the configurations is a network configuration.
