If you are using Oracle Clusterware 10gR2 or above for RAC or just for a single instance using ASM, the Clusterware automatically starts and stops the Oracle database instances and listeners, so the following procedures are not necessary. Where the Clusterware is not being used, these methods allow you to automate the startup and shutdown of databases on Linux.
The "su" Command
The following represents the Oracle recommended method for automating database startup and shutdown of Oracle 9i instances on Linux, but it works equally well for Oracle 10g, 11G and 12c also. It can be used on any RHEL-style distribution, including Oracle Linux, up to an including RHEL7.
Once the instance is created, edit the "/etc/oratab" file setting the restart flag for each instance to 'Y'.
PROD:/u01/app/oracle/product/11.2.0/PROD:Y
Create a file called "/etc/init.d/oracle" as the root user, containing the following code.
#!/bin/sh
#
# /etc/rc.d/init.d/dbase
# Description: Starts and stops the Oracle database and listeners
# See how we were called.

Associate the "oracle" service with the appropriate run levels and set it to auto-start using the following command.
chkconfig --add oracle
For Multiple database please follow the steps. Edit the dbstart file on your first ORACLE_HOME as per the /etc/oratab and add the bellow lines to add the multiple listeners.
cd $ORACLE_HOME/bin
vim dbstart (Edit the file and add the oracle home and listener name)
