Oracle Expdp Impdp 数据泵导入导出

导出 

sql>conn username/password@orcl as sysdba;
sql>create directory dmp_dir as 'd:\temp';
sql>select * from dba_directories;

sql>grant read,write on directory dmp_dir to username;

sql>grant exp_full_database to username;
sql>grant imp_full_database to username;

sql>alter user username quota unlimited on user_tablespace ; 

c:\expdp username/password@ip/orcl DIRECTORY=dmp_dir SCHEMAS=schema_name(username) dumpfile=XXX.dmp logfile=XXX.log 

-- content=metadata_only : 表结构
-- include=TABLE,VIEW,Procedure,sequence (表、视图、存储过程、序列)
c:\expdp username/password@ip/orcl DIRECTORY=dmp_dir SCHEMAS=schema_name(username) dumpfile=XXX.dmp logfile=XXX.log CONTENT=METADATA_ONLY INCLUDE=TABLE,VIEW,Procedure,sequence

新建逻辑目录，Oracle不会自动建立实际的物理目录“D:\temp”（务必先手动建立此目录而后再执行oracle 导出目录定义），仅仅是进行定义逻辑路径dmp_dir；   

sql>conn username/password@orcl as sysdba;
sql>create directory dmp_dir as 'd:\temp';
sql>select * from dba_directories;

oracle 定义路径前必须建立物理地址，否则会出现以下错误。   

    ORA-39002: invalid operation
    ORA-39070: Unable to open the log file.
    ORA-29283: invalid file operation
    ORA-06512: at "SYS.UTL_FILE", line 536
    ORA-29283: invalid file operation

确认目录存在，当出现以下错误，看看是否有受权 

ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-39087: directory name DUMP_DIR is invalid

解决方法：

grant read,write on directory dump_dir to username;

导出时出现以下错误，表示没有给用户受权（grant exp_full_database to username;）

    ORA-31631: privileges are required

    ORA-39161: Full database jobs require privileges

导入时出现以下错误，表示没有给用户受权（grant imp_full_database to username;）

    ORA-31631: privileges are required

    ORA-39122: Unprivileged users may not perform REMAP_SCHEMA remappings.

表空间已满提示错误：

    ORA-31626: job does not exist
    ORA-31633: unable to create master table "DRM_PFM.SYS_EXPORT_FULL_06"
    ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
    ORA-06512: at "SYS.KUPV$FT", line 1020
    ORA-01658: unable to create INITIAL extent for segment in tablespace TS_PFM

查看表空间状况：

SELECT a.tablespace_name "表空间名",
       total / 1024 / 1024 "表空间大小单位[M]",
       free / 1024 / 1024 "表空间剩余大小单位[M]",
       (total - free) / 1024 / 1024 "表空间使用大小单位[M]",
       Round((total - free) / total, 4) * 100 "使用率   [%]"
  FROM (SELECT tablespace_name, Sum(bytes) free
          FROM DBA_FREE_SPACE
         GROUP BY tablespace_name) a,
       (SELECT tablespace_name, Sum(bytes) total
          FROM DBA_DATA_FILES
         GROUP BY tablespace_name) b
 WHERE a.tablespace_name = b.tablespace_name;

解决方法：

-- 增长表空间容量
ALTER DATABASE DATAFILE 'D:\DEVELOP\DATABASE\TABLESPACE\TS_PFM.DBF' RESIZE 200M;

-- 修改表空间自动扩展
ALTER DATABASE DATAFILE 'D:\DEVELOP\DATABASE\TABLESPACE\TS_PFM.DBF' AUTOEXTEND ON NEXT 100M MAXSIZE 1G;

        若是表空间设置了自动扩展，查询到的表空间容量快满了，手动执行表空间容量增长；个人就是设置了表空间自动扩展的，可是expdp 导出的时候仍是报错，经过手动增长容量解决问题。   

文件已存在提示错误，删除以前由于出现错误建立的文件从新执行便可。

    ORA-39001: invalid argument value
    ORA-39000: bad dump file specification
    ORA-31641: unable to create dump file "d:\temp\oracle\drm_pfm0711.dmp"
    ORA-27038: created file already exists
    OSD-04010: <create> option specified, file already exists

根据用户导出数据提示

ORA-31626: job does not exist
ORA-31633: unable to create master table "DRM_PFM.SYS_EXPORT_SCHEMA_05"
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT", line 1020
ORA-01950: no privileges on tablespace 'TS_PFM'

解决办法

SQL> alter user username quota unlimited on tablespace_name ;

 

导入

角色确实不存在忽略便可，若是仍是导入不了看看是不是表空间不足。
