Listener unable to start, TNS 01150

Question

HI ALL,
I am using oracle 10g in RHEL, i am trying to start the listener, but its not starting.
This is my listener.ora file:
LISTENER =
     (ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
     (ORACLE_HOME = D:\oracle\product\10.1.0\Db_1\)
     (SID_NAME = primary)
(SID_DESC =
     (ORACLE_HOME = D:\oracle\product\10.1.0\Db_1\)
     (SID_NAME = pstandby)
Kindly advice me. primary and pstandby both are connection string

As per your information oracle 10g on RHEL this listener file does not seem to be generated on Linux, seems more like from windows installation.
1) was the listener file modified or hostname changed or copied from other server?
2) What does tnsping to your primary or pstandby show.
3) try removing any space in the listener definition and then restart listener
LISTENER =(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=localhost)(PORT=1521)))
SID_LIST_LISTENER =(SID_LIST=(SID_DESC=(ORACLE_HOME=D:\oracle\product\10.1.0\Db_1\)(SID_NAME=primary))
(SID_DESC=(ORACLE_HOME=D:\oracle\product\10.1.0\Db_1\)(SID_NAME=pstandby)))
*note* also try the actual ip address instead of localhostSanjay
