Database Autostartup Steps :
1> Make /etc/oratab file entry Y as :
orcl:/u01/app/oracle/product/10.2.0/db_1:Y
2>Create a file called "/etc/rc.d/init.d/oracle" as the root user, containing the following.
--------------------------------------
#!/bin/sh
# chkconfig: 345 99 10
# description: Oracle auto start-stop script.
#
# Set ORA_HOME to be equivalent to the $ORACLE_HOME
# from which you wish to execute dbstart and dbshut;
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database in ORA_HOME.
ORA_HOME=/u01/app/oracle/product/10.2.0/db_1
ORA_OWNER=oracle
if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi
case "$1" in
'start')
# Start the Oracle databases:
# The following command assumes that the oracle login
# will not prompt the user for any values
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl start"
su - $ORA_OWNER -c $ORA_HOME/bin/dbstart
;;
'stop')
# Stop the Oracle databases:
# The following command assumes that the oracle login
# will not prompt the user for any values
su - $ORA_OWNER -c $ORA_HOME/bin/dbshut
su - $ORA_OWNER -c "$ORA_HOME/bin/lsnrctl stop"

3>Use the chmod command to set the privileges to 755.
