1修改oratab文件

vi /etc/oratab#把后台一行的N改为Ydb01:/usr/oracle/app/product/11.2.0/dbhome_1:Y

2如果安装时/home/oracle/.bash_profile没加export ORACLE_SID=orcl，则要加上(/home/oracle/.bash_profile中的oracle为oracle的用户)

3编辑服务文件，加入开机启动

#!/bin/bash# oracle: Start/Stop Oracle Database 11g R2## chkconfig: 345 90 10# description: The Oracle Database is an Object-Relational Database Management System.## processname: oracle. /etc/rc.d/init.d/functionsLOCKFILE=/var/lock/subsys/oracle# 需要修改ORACLE_HOME和ORACLE_USER变量为自己安装环境的实际变量ORACLE_HOME=/data/oracle/product/12.1.0/db_1ORACLE_USER=oraclecase "$1" in'start')    if [ -f $LOCKFILE ]; then        echo $0 already running.        exit 1    fi    echo -n $"Starting Oracle Database:"    su - $ORACLE_USER -c "$ORACLE_HOME/bin/dbstart $ORACLE_HOME"    su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl start dbconsole"    touch $LOCKFILE    ;;'stop')    if [ ! -f $LOCKFILE ]; then        echo $0 already stopping.        exit 1    fi    echo -n $"Stopping Oracle Database:"    su - $ORACLE_USER -c "$ORACLE_HOME/bin/dbshut $ORACLE_HOME"    su - $ORACLE_USER -c "$ORACLE_HOME/bin/emctl stop dbconsole"    rm -f $LOCKFILE    ;;'restart')    $0 stop    $0 start    ;;'status')    if [ -f $LOCKFILE ]; then        echo $0 started.    else        echo $0 stopped.    fi    ;;*)    echo "Usage: $0 [start|stop|status]"    exit 1esacexit 0
