problem in listner

[gopu_g]

I am not able to startup the listner, earlier it was running fine and i did't alter the listner file also.but when i shut down the db and started the listner i am getting this error.

TNS-01155: Incorrectly specified SID_LIST_LISTENER parameter in LISTENER.ORA
NL-00303: syntax error in NV string



this is my listner.ora file

# LISTENER.ORA Network Configuration File: /oracle/u01/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC))
)
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = blrgesun)(PORT = 1521))
)
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /oracle/u01)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = blrgeora)
(ORACLE_HOME = /oracle/u01)
(SID_NAME = blrgeora)
)
)


Thanks in advance

You need to re-create the listener.ora using the Net8 Assistant/netca

ya for me also the problem is solved, thanks for the solution,but i did't get what is the error in that.

The listener.ora file was copied from a previous version of Oracle.
The file contains different syntax for the database and environment
variables. When you try to use this file with Oracle v8.0.5, it
cannot understand the parameters listed in the listener.ora file.

gopu_g,
One possibility is that your original listener.ora file got deleted from OS. And when you started the listener next time, it got created with default parameters, which weren't as per your original listener's parameters. It could also be that your original listener's name was something else from the default LISTENER.

HTH,
