oracle11g windows迁移至linux

原创cube_six_hujw 最后发布于2018-03-02 11:46:06

概述：跨操作系统平台数据库迁移，windows to linux 步骤记录；

实验步骤：

（一）、linux平台安装好数据库软件及配置好监听；

（二）、备份windows数据库；

（三）、linux平台进行数据库恢复操作；

（四）、linux平台进行数据库恢复后的相关操作；

windows 备份数据库：

run {
configure device type disk parallelism 4;
backup database format ‘C:\bak\full_%U‘;
 }

模拟数据库还在运行，多切换几个日志进行归档：

alter system switch logfile; （多次执行）

备份控制文件

alter database backup  controlfile to ‘C:\bak\ctl.bak‘;

将备份文件、备份控制文件、全量的归档 传输与linux平台

linux平台进行恢复操作：

启动linux至nomount状态：

[[email protected] dbs]$ cat initcube.ora 
db_name=‘cube‘
memory_target=500M
processes = 150
audit_file_dest=‘/u01/ora/app/admin/cube/adump‘

undo_tablespace=‘UNDOTBS1‘
control_files = (/u01/ora/app/data/control1.ctl, /u01/ora/app/data/control2.ctl)

oracle11g windows迁移至linux的相关文章

MySQL数据库从windows迁移到linux

前几天搭建了lamp环境,想把之前写的小东西迁到linux上运行,涉及到把mysql数据库的文件迁移到linux上,直接用fileZilla传过去应该不行,我试了下,反正没成功.下面是我采用的方法: (一)用mysqldump命令导出数据库文件: 在windows下cd到Mysql的bin目录: c:/data.txt这个目录和导出的文本名可以自己随便取,-B 后面的是表名,我要导出的表明叫user.输入密码之后,就可以去保存的目录下看看有没有数据文件了,有的话就成功了,感觉可能失败的地方就是没

Mysql从Windows迁移到Linux，遇到的坑

最近有个项目从Windows上迁移到Linux上,数据库在迁移成功,但是项目无法启动 [BPM] 2018-09-23 17:04:52 ERROR [localhost-startStop-1] ContextLoader.initWebApplicationContext(307) | Context initialization failed org.springframework.beans.factory.BeanCreationException: Error creating be

将mysql数据从Windows迁移到Linux中

1.先在windows上将数据都导出一个文件.(这里以某个数据库为例) 导出整个数据库 mysqldump -u 用户名 -p密码 数据库名 > 导出的文件名 导出指定表 mysqldump -u 用户名 -p密码 数据库名 表名1 表名2 ... > 导出的 文件名 2.将数据从Windows拷贝到Linux中. 3.登录Linux的MySql数据库 4.创建与windows同名的数据库名. mysql> create database qt; 查看字符集是否与windows一致,不一

MYSQL大小写（由于数据由windows迁移到Linux导致）

今日从sqlserver上迁移了一个数据库到Linux的MySQL中,迁移成功了,但是应用却跑不通,查看日志发现,提示找不到表,我注意到,表名都是存在大小写的,而MySQL中的表名都是小写的.这提醒了我,莫非MySQL 中表名是大小写敏感的?一查果然如此.解决方案如下: 1.用ROOT登录,修改/etc/my.cnf 2.在[mysqld]下加入一行:lower_case_table_names=1 3.重新启动数据库即可 其中 lower_case_table_names=1 参数缺省地在 W

Windows下Svn服务器迁移至linux

Svn windows迁移至linux 需求:svn服务器从windows系统无缝迁移至linux系统中 实施: 一:准备工作 1,linux服务器一台 2,原svn-windows服务器安装代码及配置文件一份. 二:步骤 01:windows服务器操作 如图为windows svn 服务器图例 查找他的目录地址为:D:\Repositories 因为只有一个项目故进入此项目里找到需要的文件 注释:  conf  为用户账户及密码配置文件 Dav   为web认证文件 Db   为数据文件 Ho

如何利用mono把.net windows service程序迁移到linux上

How to migrate a .NET Windows Service application to Linux using mono? 写在最前:之所以用要把windows程序迁移到Linux上,主要是由于一些成本问题,这个就不多解释了. 如何把之前用.net写的windows服务程序迁移到linux上运行.答案是有很多种的,今天我只提一下mono(我只实验了mono,呵呵). 如何在Linux部署mono,并成功的运行.net程序,还请大家多多查询吧,我在这方面也只是搭建成功了,遇到的问

SVN从win迁移到Linux上

工作需要把SVN从win迁移到Linux上,花了几天时间看资料搞定,简单记录一下: 公司用的SVN环境为 Windows server 2003 ,VisualSVN 2.1.5版本 1.dump出SVN数据并上传到Linux 在Repositories处先导出其项目名列表,然后编写一个简单的bat脚本进行dump: 比如: @echo off svnadmin dump C:\Repositories\baijiu > C:/test/baijiu.dump svnadmin dump C:\
