c:\expdp username/[email protected]/orcl DIRECTORY=dmp_dir SCHEMAS=schema_name(username) dumpfile=XXX.dmp logfile=XXX.log

新建逻辑目录，Oracle不会自动创建实际的物理目录“D:\temp”(务必先手动创建此目录然后再执行oracle 导出目录定义)，仅仅是进行定义逻辑路径dmp_dir；
sql>conn username/[email protected] as sysdba;
sql>create directory dmp_dir as 'd:\temp';
sql>select * from dba_directories;
oracle 定义路径前必须创建物理地址，不然会出现如下错误。
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，当出现如下错误，看看是否有授权
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;
导出时出现如下错误，表示没有给用户授权(grant exp_full_database to username;)
ORA-31631: privileges are required
ORA-39161: Full database jobs require privileges
导入时出现如下错误，表示没有给用户授权(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$FT", line 1020
ORA-01658: unable to create INITIAL extent for segment in tablespace TS_PFM
查看表空间情况：
SELECT a.tablespace_name "表空间名",
total / 1024 / 1024 "表空间大小单位[M]",
free / 1024 / 1024 "表空间剩余大小单位[M]",
(total - free) / 1024 / 1024 "表空间使用大小单位[M]",
Round((total - free) / total, 4) * 100 "使用率 [%]"
FROM (SELECT tablespace_name, Sum(bytes) free
FROM DBA_FREE_SPACE
GROUP BY tablespace_name) a,
(SELECT tablespace_name, Sum(bytes) total
FROM DBA_DATA_FILES
GROUP BY tablespace_name) b
WHERE a.tablespace_name = b.tablespace_name;
解决方法：
-- 增加表空间容量
ALTER DATABASE DATAFILE 'D:\DEVELOP\DATABASE\TABLESPACE\TS_PFM.DBF' RESIZE 200M;
-- 修改表空间自动扩展
ALTER DATABASE DATAFILE 'D:\DEVELOP\DATABASE\TABLESPACE\TS_PFM.DBF' AUTOEXTEND ON NEXT 100M MAXSIZE 1G;
如果表空间设置了自动扩展，查询到的表空间容量快满了，手动执行表空间容量增加；我的就是设置了表空间自动扩展的，但是expdp 导出的时候还是报错，通过手动增加容量解决问题。
文件已存在提示错误，删除之前因为出现错误创建的文件重新执行即可。
ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-31641: unable to create dump file "d:\temp\oracle\drm_pfm0711.dmp"
ORA-27038: created file already exists
OSD-04010: option specified, file already exists
根据用户导出数据提示
ORA-31626: job does not exist
ORA-31633: unable to create master table "DRM_PFM.SYS_EXPORT_SCHEMA_05"
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$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即可，如果还是导入不了看看是否是表空间不足。
