目录
Oracle数据泵Expdp/impdp导入导出详解
一、准备工作
- 创建directory 目录，用户导出的数据存放于此目录
SQL> create directory EXPDP_DUMP as '/test/expdp_dump';
2、查看创建的directory
SQL> select * from dba_directories;
3、授予EXPDP_DUMP目录权限给导出用户scott
SQL> grant read,write on directory EXPDP_DUMP to test;
4、删除 EXPDP_DUMP
SQL> drop directory EXPDP_DUMP;
二、数据导出（expdp）
- 参数ATTACH：连接到现有作业。
如：连接已经停止的作业继续备份

2、参数CLUSTER：利用集群资源并将 worker 进程分布在 Oracle RAC 上。
有效的关键字值为: [Y] 和 N。
如：
| 备份时worker 进程分布在 Oracle RAC 的多个实例上默认cluster=y，所以DIRECTORY必须在共享磁盘上，如果没有设置共享磁盘还是指定cluster=no来防止报错。 [oracle@neb /test/expdp_dump]$ expdp \"/ as sysdba \" DIRECTORY=EXPDP_DUMP LOGFILE=test.log DUMPFILE=testexp%u.dmp schemas=scott cluster=n parallel=4 Export: Release 11.2.0.3.0 - Production on Thu Dec 3 18:02:36 2015 Copyright (c) 1982,Data Mining and Real Application Testing options Starting "SYS"."SYS_EXPORT_SCHEMA_01": "/******** AS SYSDBA" DIRECTORY=EXPDP_DUMP LOGFILE=test.log DUMPFILE=testexp%u.dmp schemas=scott cluster=n parallel=4 Estimate in progress using BLOCKS method...

6、参数ESTIMATE={BLOCKS | STATISTICS}，设置为BLOCKS时,oracle会按照目标对象所占用的数据块个数乘以数据块尺寸估算对象占用的空间,设置为STATISTICS时,根据最近统计值估算对象占用空间

7、参数ESTIMATE_ONLY={Y|N} 指定是否只估算导出作业所占用的磁盘空间,默认值为N，设置为Y时,导出作用只估算对象所占用的磁盘空间,而不会执行导出作业,为N时,不仅估算对象所占用的磁盘空间,还会执行导出操作
如：
