c:\expdp username/[email protected]/orcl DIRECTORY=dmp_dir SCHEMAS=schema_name(username) dumpfile=XXX.dmp logfile=XXX.log
-- content=metadata_only : 表結構
-- include=TABLE,VIEW,Procedure,sequence (表、視圖、存儲過程、序列)
c:\expdp username/[email protected]/orcl DIRECTORY=dmp_dir SCHEMAS=schema_name(username) dumpfile=XXX.dmp logfile=XXX.log CONTENT=METADATA_ONLY INCLUDE=TABLE,VIEW,Procedure,sequence
建立邏輯目錄，Oracle不會自動建立實際的實體目錄“D:\temp”(務必先手動建立此目錄然後再執行oracle 導出目錄定義)，僅僅是進行定義邏輯路徑dmp_dir；
sql>conn username/[email protected] as sysdba;
sql>create directory dmp_dir as 'd:\temp';
sql>select * from dba_directories;
oracle 定義路徑前必須建立實體位址，不然會出現如下錯誤。
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
确認目錄存在，當出現如下錯誤，看看是否有授權
ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-39087: directory name DUMP_DIR is invalid
解決方法：
grant read,write on directory dump_dir to username;
導出時出現如下錯誤，表示沒有給使用者授權(grant exp_full_database to username;)
ORA-31631: privileges are required
ORA-39161: Full database jobs require privileges
導入時出現如下錯誤，表示沒有給使用者授權(grant imp_full_database to username;)
ORA-31631: privileges are required
ORA-39122: Unprivileged users may not perform REMAP_SCHEMA remappings.
表空間已滿提示錯誤：
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$FT", line 1020
ORA-01658: unable to create INITIAL extent for segment in tablespace TS_PFM
檢視表空間情況：
SELECT a.tablespace_name "表空間名",
total / 1024 / 1024 "表空間大小機關[M]",
free / 1024 / 1024 "表空間剩餘大小機關[M]",
(total - free) / 1024 / 1024 "表空間使用大小機關[M]",
Round((total - free) / total, 4) * 100 "使用率 [%]"
FROM (SELECT tablespace_name, Sum(bytes) free
FROM DBA_FREE_SPACE
GROUP BY tablespace_name) a,
(SELECT tablespace_name, Sum(bytes) total
FROM DBA_DATA_FILES
GROUP BY tablespace_name) b
WHERE a.tablespace_name = b.tablespace_name;
解決方法：
-- 增加表空間容量
ALTER DATABASE DATAFILE 'D:\DEVELOP\DATABASE\TABLESPACE\TS_PFM.DBF' RESIZE 200M;
-- 修改表空間自動擴充
ALTER DATABASE DATAFILE 'D:\DEVELOP\DATABASE\TABLESPACE\TS_PFM.DBF' AUTOEXTEND ON NEXT 100M MAXSIZE 1G;
如果表空間設定了自動擴充，查詢到的表空間容量快滿了，手動執行表空間容量增加；我的就是設定了表空間自動擴充的，但是expdp 導出的時候還是報錯，通過手動增加容量解決問題。
檔案已存在提示錯誤，删除之前因為出現錯誤建立的檔案重新執行即可。
ORA-39001: invalid argument value
ORA-39000: bad dump file specification
ORA-31641: unable to create dump file "d:\temp\oracle\drm_pfm0711.dmp"
ORA-27038: created file already exists
OSD-04010: option specified, file already exists
根據使用者導出資料提示
ORA-31626: job does not exist
ORA-31633: unable to create master table "DRM_PFM.SYS_EXPORT_SCHEMA_05"
ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95
ORA-06512: at "SYS.KUPV$FT", line 1020
ORA-01950: no privileges on tablespace 'TS_PFM'
解決辦法
SQL> alter user username quota unlimited on tablespace_name ;
導入
角色确實不存在忽略即可，如果還是導入不了看看是否是表空間不足。
