TNS adapter error, No listener

Hi gurus, I am using oracle 8.1.7 std edition on RH Linux ES3.0. When I started the d/b I could not connect to oracle because of TNS error. I am trying to connect to oracle from the server (linux box itself) there are no clients connected to the server.

In order for the Oracle server to start automatically at system boot time, create the file /etc/init.d/oracle like this:

#!/bin/bash
#
# Run-level Startup script for the Oracle Instance and Listener
#
# chkconfig: 345 91 19
# description: Startup/Shutdown Oracle listener and instance

ORA_HOME="/u01/app/oracle/product/9.2.0.1.0"
ORA_OWNR="oracle"

# if the executables do not exist -- display error

if [ ! -f $ORA_HOME/bin/dbstart -o ! -d $ORA_HOME ]
then
        echo "Oracle startup: cannot start"
        exit 1
fi

# depending on parameter -- startup, shutdown, restart
# of the instance and listener or usage display

case "$1" in
    start)
        # Oracle listener and instance startup
        echo -n "Starting Oracle: "
        su - $ORA_OWNR -c "$ORA_HOME/bin/lsnrctl start"
        su - $ORA_OWNR -c $ORA_HOME/bin/dbstart
        touch /var/lock/subsys/oracle
        echo "OK"
        ;;
    stop)
       # Oracle listener and instance shutdown
        echo -n "Shutdown Oracle: "
        su - $ORA_OWNR -c "$ORA_HOME/bin/lsnrctl stop"
        su - $ORA_OWNR -c $ORA_HOME/bin/dbshut
        rm -f /var/lock/subsys/oracle
        echo "OK"
        ;;
    reload|restart)
        $0 stop
        $0 start
        ;;
    *)
        echo "Usage: $0 start|stop|restart|reload"
        exit 1
esac
exit 0

 

Now run chkconfig oracle for updating the run level information.

Try service oracle start|stop|restart to check that everything works as expected now.

You need to start the listener.   Before we go through the steps:  Has this ever worked?

also post the output from the following OS command:
lsnrctl status

So basically you're saying that the listener isn't starting up on boot of the box?

I'm not a Linux person and I've been away from UNIX for a few years but there should be symbolic links from the Linux startup scripts directories over to a script in $ORACLE_HOME/bin that should be starting the listener.  These links should have been created for you by the root.sh script.

After you installed Oracle, did you run the root.sh script as the root user?

if you are running from the server box itself then you should not need a listener.

ORACLE_SID=<DBSID>
export ORACLE_SID

sqlplus user/passwd

Cheers

JJSmith is correct. However, if you are planning on using DBA Studio or any other applications from the same machine then listener process will be required.
