Hi everybody,
I am having difficulty in starting the listener process. Following errors are being generated when I try to start.:

LSNRCTL> status
Connecting to (DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=cosngtvs2)(PORT=1521)))
TNS-01103: Protocol specific component of the address is incorrectly specified
TNS-12541: TNS:no listener
TNS-12560: TNS:protocol adopter error
TNS-00511: No listener
DEC OSF/1 AXP Error:61: Connection refused


LSNRCTL> start
Starting /tools/oracle/product/8.1.6.0.0 - Production
NL-00280: error creating log stream /tools/oracle/product/8.1.6/network/log/listener.log
NL-00278: cannot open log file
SNL-00016: snlfohd: error opening file
DEC OSF/1 AXP Error:13: Permission denied

Can someone help me in identifying the problem and starting the process?
