Automating Database Startup and Shutdown on Linux 11g R2

I followed this link


Create a file called "/etc/init.d/dbora" as the root user, containing the following
vi /etc/init.d/dbora #!/bin/sh
# chkconfig: 345 99 10
# description: Oracle auto start-stop script.
#
# Set ORA_OWNER to the user id of the owner of the
# Oracle database software.

ORA_OWNER=oracle

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 "/home/oracle/scripts/startup.sh >> /home/oracle/scripts/startup_shutdown.log 2>&1"
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 "/home/oracle/scripts/shutdown.sh >> /home/oracle/scripts/startup_shutdown.log 2>&1"
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

Next, we must create the "startup.sh" and "shutdown.sh" scripts in the "/home/oracle/scripts". First create the directory.

# mkdir -p /home/oracle/scripts
# chown oracle.oinstall /home/oracle/scripts


The "/home/oracle/scripts/startup.sh" script should contain the following commands.


#!/bin/bash

export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=maniner.domain
export ORACLE_UNQNAME=orcl
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export PATH=/usr/sbin:$ORACLE_HOME/bin:$PATH

export ORACLE_SID=orcl
ORAENV_ASK=NO
. oraenv
ORAENV_ASK=YES

# Start Listener
lsnrctl start

# Start Database
sqlplus / as sysdba << EOF
STARTUP;
EXIT;
EOF


The "/home/oracle/scripts/shutdown.sh" script is similar.


#!/bin/bash

export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_HOSTNAME=maniner.domain
export ORACLE_UNQNAME=orcl
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/11.2.0/db_1
export PATH=/usr/sbin:$ORACLE_HOME/bin:$PATH

export ORACLE_SID=orcl
ORAENV_ASK=NO
. oraenv
ORAENV_ASK=YES

# Stop Database
sqlplus / as sysdba << EOF
SHUTDOWN IMMEDIATE;
EXIT;
EOF

# Stop Listener
lsnrctl stop



Note. You could move the environment settings into the "dbora" file or into a separate file that is sourced in the startup and shutdown script. I kept it local to the script so you could see the type of things that need to be set in case you have to write a script to deal with multiple installations, instances and listeners.

Make sure the permissions and ownership of the files is correct.

# chmod u+x /home/oracle/scripts/startup.sh /home/oracle/scripts/shutdown.sh
# chown oracle.oinstall /home/oracle/scripts/startup.sh /home/oracle/scripts/shutdown.sh



The listener and database will now start and stop automatically with the machine. You can test them using the following command as the "root" user.

# service dbora start
# service dbora stop




Check by rebooting the system ,its magic :) Oracle will start by itself
