oracle启动脚本

1.修改oratab,因为我们需要使用dbstart utility

[root@ora01 ~]# vi /etc/oratab
orcl:/u01/app/oracle/product/10.2.0/db_1:Y

2.修改启动文件/u01/app/oracle/product/10.2.0/db_1/bin/dbstart

78 ORACLE_HOME_LISTNER=/u01/app/oracle/product/10.2.0/db_1/

3.增加启动脚本touch /etc/init.d/oracle;chmod +x /etc/init.d/oracle

#!/bin/bash
#/etc/init.d/oracle  chmod +x oracle
# oracle This shell script takes care of starting and stopping
# the MySQL subsystem (mysqld).
# chkconfig: - 90 10
# description: Oracle database server.
# processname: oracle
ORA_HOME=/u01/app/oracle/product/10.2.0/db_1
ORA_OWNER=oracle

prog="Oracle"

# Source function library.
. /etc/rc.d/init.d/functions

if [ ! -f $ORA_HOME/bin/dbstart ]
then
echo "Oracle startup: cannot start"
exit
fi

start(){
su - $ORA_OWNER -c $ORA_HOME/bin/dbstart >/dev/null 2>&1 &
ret=$?
if [ $ret -eq 0 ]; then
action $"Starting $prog: " /bin/true
else
action $"Starting $prog: " /bin/false
fi
[ $ret -eq 0 ] && touch /var/lock/subsys/oracled
return $ret
}

stop(){
su - $ORA_OWNER -c $ORA_HOME/bin/dbshut >/dev/null 2>&1
ret=$?
if [ $ret -eq 0 ]; then
action $"Stopping $prog: " /bin/true
else
action $"Stopping $prog: " /bin/false
fi
[ $ret -eq 0 ] && rm -f /var/lock/subsys/oracled
return $ret
}
restart(){
stop
start

}
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
restart)
restart
;;
condrestart)
condrestart
;;
*)
echo $"Usage: $0 {start|stop|restart}"
exit 1
esac

4.以root用户启动关闭oracle

[root@ora01 ~]# /etc/init.d/oracle start
[root@ora01 ~]# /etc/init.d/oracle stop

在使用drbd，heartbeat做HA时可以将listener和数据库启动分开。
