安装Database软件……

升级Database软件……

以oracle用户执行netca……

#设置开机启动数据库和监听
1、#在/etc/rc.local中加入
su - oracle -c "lsnrctl start"
su - oracle -c "dbstart"
2、#修改/etc/oratab中内容
$ORACLE_SID:$ORACLE_HOME:Y
3、修改$ORACLE_HOME/bin/dbstart文件中
3.1、ORACLE_HOME_LISTENER=$ORACLE_HOME
3.2、LOG=$ORACLE_HOME_LISTENER/network/log/listener.log
4、以root身份执行
cd /etc/init.d
touch oracledb
