To start and stop Oracle 10g using the "wajig start|stop" commands, we need to edit the /etc/oratab file, and create the appropriate script in /etc/init.d.
First edit the /etc/oratab file. The format of this file is:
SID:ORACLE_HOME:AUTO_START |
Put a Y in the AUTO_START field of the databases you want to start
automagically, and a N for the ones you don't. Your file might look
like this to start databases test1 and test2, and not start test3:
test1:/u01/app/oracle/product/10.1.0/db_1:Y test2:/u01/app/oracle/product/10.1.0/db_1:Y test3:/u01/app/oracle/product/10.1.0/db_1:N |
Now we need to create the init.d script.
#!/bin/bash
#
# Run-level Startup script for the Oracle Instance and Listener
#
# chkconfig: 345 91 19
# description: Startup/Shutdown Oracle listener and instance
ORA_HOME="/u01/app/oracle/product/10.1.0/Db\_1"
ORA_OWNR="oracle"
# if the executables do not exist -- display error
if [ ! -f $ORA_HOME/bin/dbstart -o ! -d $ORA_HOME ]
then
echo "Oracle startup: cannot start"
exit 1
fi
# depending on parameter -- startup, shutdown, restart
# of the instance and listener or usage display
case "$1" in
start)
# Oracle listener and instance startup
echo -n "Starting Oracle: "
su - $ORA_OWNR -c "$ORA_HOME/bin/lsnrctl start"
su - $ORA_OWNR -c $ORA_HOME/bin/dbstart
touch /var/lock/subsys/oracle
echo "OK"
;;
stop)
# Oracle listener and instance shutdown
echo -n "Shutdown Oracle: "
su - $ORA_OWNR -c "$ORA_HOME/bin/lsnrctl stop"
su - $ORA_OWNR -c $ORA_HOME/bin/dbshut
rm -f /var/lock/subsys/oracle
echo "OK"
;;
reload|restart)
$0 stop
$0 start
;;
*)
echo "Usage: $0 start|stop|restart|reload"
exit 1
esac
exit 0
|
(You may need to change the listener.ora to have the IP of the box, as opposed to the hostname, otherwise clients machines may not be able to connect.)
To make the script run at boot-time, and let you "wajig start|stop
oracle", do the following:
ln -s /etc/init.d/oracle /etc/rc.d/rc2.d/S99oracle ln -s /etc/init.d/oracle /etc/rc.d/rc3.d/S99oracle ln -s /etc/init.d/oracle /etc/rc.d/rc4.d/S99oracle ln -s /etc/init.d/oracle /etc/rc.d/rc0.d/K01oracle ln -s /etc/init.d/oracle /etc/rc.d/rc6.d/K01oracle |
Now we can start and stop oracle by:
wajig start oracle wajig stop oracle |
