Oracle完整数据库实例迁移
[日期：2011-12-20] 来源：Linux社区 作者：sysadmin [字体：]
需求分析:
将源库所有表结构、表数据及表间约束关系整体迁移到目标实例；
删除目标数据库的所有表和用户，重建目标数据库的用户：
drop user user_name cascade;
create user user_name identified by password default tablespace tablespace_name;
grant connect,dba to user_name;
源库操作：
源库指定用户下导出所有表：
Exp username/pwd@link_name file=dmpfilename owner=user_name rows=y log=fullpath_logfilename
目标库操作：
导入数据不要约束和索引：
imp username/pwd@link_name file=dmpfilename rows=y ignore=y feedback=10000 constraints=n indexes=n log=fullpath_logfile.log full=y
导入约束和索引不导数据
imp username/pwd@link_name file=dmpfilename rows=n ignore=y constraints=y indexes=y log=fullpath_logfile.log full=y
验证迁移结果
在源、目标库分别运行下面脚本
