从oracledatabase 10g开始引入了data pump(数据泵)工具，它提供了一种基于服务器的数据导出导入使用程序。 所有的data pump都作为一个服务器进程，数据不再必须由一个客户程序处理。Data Pump工具的导出和导入实现Oracle数据库之间数据的传输。
Oracle数据泵(Data Dump)使用过程当中经常会遇到一些奇奇怪怪的错误案例，下面总结一些自己使用数据泵(Data Dump)过程当中遇到的问题以及解决方法。都是在使用过程中遇到的问题，以后陆续遇到数据泵(Data Dump)的错误案例，都会补充在此篇。
错误案例1：
ORA-39065： DISPATCH 中出现意外的主进程异常错误；ORA-44002: 对象名无效
Windows 平台错误提示：
Linux平台错误提示
解决方法：
[oracle@DB-Server admin]$ oerr ora 39065 39065, 00000, "unexpected master process exception in %s" // *Cause: An unhandled exception was detected internally within the master // control process for the Data Pump job. This is an internal error. // messages will detail the problems. // *Action: If problem persists, contact Oracle Customer Support. [oracle@DB-Server admin]$ oerr ora 39097 39097, 00000, "Data Pump job encountered unexpected error %s" // *Cause: An unexpected, potentially non-fatal error occurred while // processing a Data Pump job. // *Action: Contact Oracle Customer Support.
执行$ORACLE_HOME/rdbms/admin目录下面的catmet2.sql，utlrp.sql 两个SQL文件即可解决这个问题。
[oracle@DB-Server ~]$ cd $ORACLE_HOME/rdbms/admin [oracle@DB-Server admin]$ sqlplus / as sysdba SQL*Plus: Release 10.2.0.1.0 - Production on Sun Sep 7 08:24:23 2014 Copyright (c) 1982, 2005, Oracle. All rights reserved. Connected to an idle instance. SQL> @catmet2.sql SQL> @utlrp.sql
错误案例2：
使用expdp/impdp时遭遇ORA-39006: internal error;ORA-39213: Metadata processing is notavailable错误
[oracle@DB-Server backup]$ impdp frnt/frnt directory=dum_dir dumpfile=20120420.FRNT_02.dmp tablespaces=TBS_TR_DATA; Import: Release 10.2.0.1.0 - 64bit Production on Wednesday, 25 April, 2012 14:41:48 Copyright (c) 2003, 2005, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production With the Partitioning, OLAP and Data Mining options ORA-39006: internal error ORA-39213: Metadata processing is not available
解决方法：
错误原因如下所示，因为Data Pump不能使用Metadata API， 这个是因为XSL stylesheets 没有正确设置缘故。需要以SYSDBA执行dbms_metadata_util.load_stylesheets
[oracle@DB-Server admin]$ oerr ora 39213 39213, 00000, "Metadata processing is not available" // *Cause: The Data Pump could not use the Metadata API. Typically, // this is caused by the XSL stylesheets not being set up properly. // *Action: Connect AS SYSDBA and execute dbms_metadata_util.load_stylesheets // to reload the stylesheets.
SQL>exec dbms_metadata_util.load_stylesheets
错误案例3：
错误如下所示：
etl@NMS_ODS_NDB1[/jkfile/klbtmp]#expdp userid=username/password@tnsname dumpfile=ref.dmp directory=DUMP_TEST schemas=ref content=all logfile=ref.log Export: Release 10.2.0.3.0 - 64bit Production on Saturday, 02 March, 2013 10:28:25 Copyright (c) 2003, 2005, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production With the Partitioning, Real Application Clusters, OLAP and Data Mining options ORA-39002: invalid operation ORA-39070: Unable to open the log file. ORA-29283: invalid file operation ORA-06512: at "SYS.UTL_FILE", line 475 ORA-29283: invalid file operation
解决方法：
出现这个错误，需要检查DIRECTORY目录,创建DIRECTORY时，ORACLE并不检查操作系统目录是否已经存在
首先检查DIRECTORY目录DUMP_TEST对应的DIRECTORY_PATH，然后检查操作系统下，验证该目录是否存在。
SQL> SELECT * FROM DBA_DIRECTORIES WHERE DIRECTORY_NAME='DUMP_TEST'; OWNER DIRECTORY_NAME DIRECTORY_PATH ------------------------ ------------------------------ ----------------- SYS DUMP_TEST /jkfile/klbtmp/ SQL>
结果检查发现该目录被删除了，创建该目录即可解决问题。
另外一种情况，如果创建DIRECTORY目录时，出现了换行，也会出现上面错误信息,这种错误玩玩很难发现，非常折腾人。所以需要非常细心。
SQL> create directory DUMP_TEST as '/jkfile/klbtmp/
';
错误案例4：
如下所示：
etl@NMS_ODS_NDB1[/jkfile/work/klb]#expdp userid=etl/sunrise@wgods1 dumpfile=ref.dmp directory=DUMP_DIR schemas=ref content=all logfile=ref.log Export: Release 10.2.0.3.0 - 64bit Production on Saturday, 02 March, 2013 10:50:25 Copyright (c) 2003, 2005, Oracle. All rights reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production With the Partitioning, Real Application Clusters, OLAP and Data Mining options ORA-31631: privileges are required ORA-39109: Unprivileged users may not operate upon other users' schemas
解决方法：
主要是etl账号缺少exp_full_database 权限，给etl账号授予exp_full_database 权限后，上述问题解决。
# su - oracle $ sqlplus / as sysdba SQL*Plus: Release 10.2.0.3.0 - Production on Sat Mar 2 10:58:37 2013 Copyright (c) 1982, 2006, Oracle. All Rights Reserved. Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production With the Partitioning, Real Application Clusters, OLAP and Data Mining options SQL> grant exp_full_database to etl; Grant succeeded.
错误案例5：
etl@NMS_ODS_NDB1[/etl1_cx/etl]expdp etl/sunrise@wgods1 dumpfile=DM.TM_ALARM_LOG.dmp directory=DUMP_DIR tables=DM.TM_ALARM_LOG query='DATE_CD >=20121201 AND DATE_CD <=20130131'; LRM-00101: unknown parameter name '>'
解决方法：
etl@NMS_ODS_NDB1[/etl1_cx/etl]expdp etl/sunrise@wgods1 dumpfile=DM.TM_ALARM_LOG.dmp directory=DUMP_DIR tables=DM.TM_ALARM_LOG query="DATE_CD \>\=20121201 AND DATE_CD \<\=20130131";
错误案例6：
LRM-00121: 'DATA_ONLY' is not an allowable value for 'compression'。如下所示：
etl@NMS_ODS_NDB1[/etl1_cx/etl]#expdp etl/sunrise@wgods1 dumpfile=ref.dmp directory=DUMP_DIR dumpfile=DM.TM_ALARM_LOG201212.dmp tables=DM.TM_ALARM_LOG COMPRESSION=DATA_ONLY query='DATE_CD >=20121201 AND DATE_CD <=20130131'; LRM-00121: 'DATA_ONLY' is not an allowable value for 'compression'
解决方法：
首先查看EXPDP工具的版本，如下所示：
etl@NMS_ODS_NDB1[/etl1_cx/etl]#expdp version Export: Release 10.2.0.3.0 - 64bit Production on Monday, 04 March, 2013 14:46:47 Copyright (c) 2003, 2005, Oracle. All rights reserved. Password:
请注意，在ORACLE 10g下 COMPRESSION只有METADATA_ONLY和NONE两个选项，ORACLE 11g下才有DATA_ONLY选项。所以报如上错误。所以在使用前，请注意一下EXPDP工具的版本。
错误案例7：
[oracle@DB-Server]$ expdp system/***** TABLES=INVENRTY.INV_STK_HD dumpfile=INV_STK_HD.dmp logfile=1.log DIRECTORY=CUR_DUMP_DIR Export: Release 10.2.0.4.0 - Production on Sunday, 14 July, 2013 8:27:16 Copyright (c) 2003, 2007, Oracle. All rights reserved. Connected to: Oracle Database 10g Release 10.2.0.4.0 - Production ORA-31626: job does not exist ORA-31637: cannot create job SYS_EXPORT_TABLE_01 for user SYSTEM ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95 ORA-06512: at "SYS.KUPV$FT_INT", line 600 ORA-39080: failed to create queues "KUPC$C_1_20130714082716" and "KUPC$S_1_20130714082716" for Data Pump job ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95 ORA-06512: at "SYS.KUPC$QUE_INT", line 1606 ORA-00832: no streams pool created and cannot automatically create one
解决方法：
这个案例我以前已经介绍过，具体参考我的博客 Expdp 导数错误 ORA-00832
错误案例8：
[oracle@testlnx01 u03]$ cd tmp/ [oracle@testlnx01 tmp]$ expdp system/***** directory=DUMPDIR dumpfile=ESCMUSER.dmp schemas=ESCMUSER logfile=ESCMUSER.log Export: Release 10.2.0.4.0 - 64bit Production on Wednesday, 27 August, 2014 16:30:46 Copyright (c) 2003, 2007, Oracle. All rights reserved. Connected to: Oracle Database 10g Release 10.2.0.4.0 - 64bit Production ORA-31626: job does not exist ORA-31633: unable to create master table "SYSTEM.SYS_EXPORT_SCHEMA_05" ORA-06512: at "SYS.DBMS_SYS_ERROR", line 95 ORA-06512: at "SYS.KUPV$FT", line 871 ORA-00959: tablespace 'TOOLS' does not exist
解决方法：
这个案例有点特别，刚遇到的时候，确实有点莫名其妙，经过苦苦求索、求证后才发现，本来有一个TOOLS的表空间，不知道是哪位头脑发热的人，居然指定SYSTEM用户的默认表空间为TOOLS，但是这个表空间又被人删除了。于是便有了这样一个案例。
SQL> ALTER USER SYSTEM DEFAULT TABLESPACE SYSTEM; User altered.
修改用户SYSTEM的默认表空间后，问题解决。
以上就是Oracle数据泵(Data Dump)使用过程当中经常会遇到一些奇奇怪怪的错误案例的详细内容，更多请关注0133技术站其它相关文章！
