auto start/stop Oracle on linux

The following sample is for Oracle 12c:

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’.

TSH1:/u01/app/oracle/product/9.2.0:Y

Create a file called “/etc/init.d/dbora” as the root user, containing the following code.

#!/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_HOME=/u01/app/oracle/product/11.1.0/db_1
#ORA_HOME=/u01/app/oracle/product/11.2.0/db_1
ORA_HOME=/u01/app/oracle/product/12.1.0/db_1
ORA_OWNER=oracle
export ORACLE_UNQNAME=db12c

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
        # Remove "&" if you don't want startup as a background process.
        su $ORA_OWNER -c "$ORA_HOME/bin/dbstart $ORA_HOME" &
        touch /var/lock/subsys/dbora
        ;;
    '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 $ORA_HOME"
        rm -f /var/lock/subsys/dbora
        ;;
esac

Use the chmod command to set the privileges to 750.

chmod 750 /etc/init.d/dbora

Associate the “dbora” service with the appropriate run levels and set it to auto-start using the following command.

chkconfig --add dbora

The relevant instances should now startup/shutdown automatically at system startup/shutdown.
