执行以下命令静默卸载Oracle数据库软件
执行以下命令静默卸载Oracle数据库软件
$./runInstaller -silent -deinstall -removeallfiles -removeAllPatches "REMOVE_HOMES=" -responseFile ~/enterprise.rsp---------------------------------------------------------------------------------------（一）图形界面开始安装：
1.以oracle用户登录X-WINDOWS系统，进行Oracle的安装（远程安装需打开XDM）：[ linux 5}
export DISPLAY=
cd /opt/database (或者你解压缩安装程序包的目录）
./runInstaller 或者./runInstaller
-ignoreSysPrereqs
过一会儿就会出现Oracle的X安装界面注意：
1、选择advance install
2、数据库home设置为/opt/oracle/10.2.0.1
3、数据库全局名称设置为ge01
4、数据库字符集选Simplified Chinese ZHS16GBK2.其他用默认设置！
注意：安装过程中会提示以root用户登陆执行一些脚本 ，执行后再按“ok”按钮继续安装。
3、登陆并启动数据库的操作。

ORACLE instance shut down.4, dbstart脚本修改
数据库创建完成后，修改vi /etc/oratab，把ge01:/opt/oracle/10.2.0.1:N那一行最后的N改成Y，
修改vi /opt/oracle/10.2.0.1/bin/dbstart中ORACLE_HOME_LISTNER=/opt/oracle/10.2.0.1
然后执行dbstart启动数据库数据库可能无法启动，报告Can’t find init file …的错误，需要复制一个初始化文件:
cp /opt/oracle/admin/ge01/pfile/init.ora.* /opt/oracle/10.2.0.1/dbs/initge01.ora
重新执行dbstart就可以了。可以执行dbshut 停止ORACLEvi /etc/rc.local 加入下面一行 起动ORACLE ON system boot
su - oracle -c "lsnrctl start"
su - oracle -c "dbstart" 5. 为了root方便管理，可以写一个启动脚本
vi /etc/init.d/ora10g
#!/bin/bash
#
# chkconfig: 2345 91 19
# description: starts the oracle listener and instance status() {
pid=`ps -ef | grep ora_pmon |
grep -v grep | awk '{print $8}'`
if [ "X$pid" = "X" ]
then
echo
"oracle10g is not running."
exit 1
else
echo
"oracle10g is running."
exit 0
fi
}case "$1" in
start)
#startup the
listener and instance
echo -n
"oracle begin to startup: "
su - oracle
-c "lsnrctl start"
su - oracle
-c dbstart
echo
"oracle10g started"
;;
stop)
# stop
listener, apache and database
echo -n
"oracle begin to shutdown:"
su - oracle
-c "lsnrctl stop"
su - oracle
-c dbshut
echo
"oracle10g shutdowned"
;;
reload|restart)
$0 stop
$0
start
;;
'status')
status
;;
*)
echo "Usage:
ora10g [start|stop|reload|restart]"
exit 1
esac
exit 0 存为ora10g后，然后
chmod a+x /etc/init.d/ora10g
即可在以后以root身份运行/etc/rc.d/init.d/ora10g start |stop 来管oracle的启动和停止了。
如果要将这个脚本加入到系统中使其可开机运行，那么要运行以下命令：
chkconfig --level 35 ora10g on
6, 关于数据库删除重新安装的问题:
1 . 去除 /usr/local/bin 目录 下的 coraenv dbhome oraenv
2 . 去除 /etc/oratab , /etc/oracle
3 . 去掉安装 目录 /opt/oracle 目录下的 product admin oradata oralnventor 目录 。
# userdel -r oracle
# groupdel dba oinstall
rm -rf /tmp/ora*
rm -rf /opt/oracle/*
rm -rf /opt/ORCLfmap
rm -f /etc/ora*
rm -f /usr/local/bin/oraenv
rm -f /usr/local/bin/coraenv
rm -f /usr/local/bin/dbhome
7.修改Oracle10g数据库字符集
