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> @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
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：

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

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> 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：

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：

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。
