Oracle 数据备份与恢复

导出数据： 编写创建路径文件：create_dir.sql create or replace directory dmpdir as 'E:\app\tmp';
grant read, write on directory dmpdir to test;
exit 编写执行导出Bat文件：export.bat sqlplus system/root123@MYTEST @create_dir.sql
expdp system/root123@MYTEST schemas=test directory=dmpdir dumpfile=MYTEST.DMP MYTEST要备份的数据库 导入数据 编写创建User文件：create_user.sqldrop user test2 cascade;
create user test2 identified by password;
grant connect, resource to test2;
create or replace directory dmpdir as 'E:\app\tmp';
grant read, write on directory dmpdir to test2;
exit 编写执行导入Bat文件：restore.bat sqlplus system/root123@localhost:1521/MYTEST @create_user.sql
impdp system/root123@localhost:1521/MYTEST schemas=test directory=dmpdir dumpfile=MYTEST.DMP table_exists_action=replace remap_schema=test:test2
