Step 1:
Login as root and create a file called /etc/init.d/oracle. Add the following lines in the script.
#!/bin/bash
#######################################################################
#
# Run-level Startup script for the Oracle Instance and Listener
#
# chkconfig: 345 98 34
# description: Startup/Shutdown script for 11g Oracle instances
#

#
# Note:
# cp $ORACLE_HOME/bin/dbstart $ORACLE_HOME/bin/dbstart.orig
# Make the following changes in $ORACLE_HOME/bin/dbstart
#
# Line#80 has the following:
# ORACLE_HOME_LISTNER=$1
#
# Replace it with the following two lines:
# export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
# ORACLE_HOME_LISTNER=$ORACLE_HOME
#
# cp $ORACLE_HOME/bin/dbshut $ORACLE_HOME/bin/dbshut.orig
# Make the following changes in $ORACLE_HOME/bin/dbshut
#
# Line#50 has the following:
# ORACLE_HOME_LISTNER=$1
#
# Replace it with the following two lines:
# export ORACLE_HOME=/u01/app/oracle/product/11.2.0/db_1
# ORACLE_HOME_LISTNER=$ORACLE_HOME
#
# save the file and proceed with the steps below
#

exit 0
clear
###################### END of SCRIPT ##############################
Step-2:
Change the permission of the script
chmod 750 /etc/init.d/oracle
Step-3:
Execute the following so that runlevel 3,4 & 5 will execute the script during system reboots.
chkconfig --level 345 oracle on
Step-4
Execute the script and verify everything is working as expected. Alternatively, you can download the script directory from here.
Additionally you can turn on and turn on with the following.
[root@bl-mm-db-dev ~]# /sbin/chkconfig oracle off
[root@bl-mm-db-dev ~]# /sbin/chkconfig --levels 345 oracle on
That's it. We are done.
