这篇文章主要介绍“怎么将Expdp备份数据转到ASM中”，在日常操作中，相信很多人在怎么将Expdp备份数据转到ASM中问题上存在疑惑，小编查阅了各式资料，整理出简单好用的操作方法，希望对大家解答”怎么将Expdp备份数据转到ASM中”的疑惑有所帮助！接下来，请跟着小编一起来学习吧！
一、问题描述
需求要使用expdp备份数据，检查系统空间很小，不够放备份文件。直接给系统加空间不就得了，可是这样一来就要耽误时间，还要联系一大堆人员。此时ASM空间是很充足的，可不可以使用呢。接着就有以下的操作了。
二、实验
1.数据库建立directory
SYS@PROD1 > create directory databk as '+data/backup'; Directory created. . [oracle@sam1 ~]$ expdp system/oracle direcotry=databk dumpfile=all.dmp full=y LRM-00101: unknown parameter name 'direcotry' [oracle@sam1 ~]$ expdp system/oracle directory=databk dumpfile=all.dmp full=y Export: Release 11.2.0.3.0 - Production on Sat Feb 15 08:13:57 2020 Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved. Connected to: Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production With the Partitioning, Real Application Clusters, Automatic Storage Management, OLAP, Data Mining and Real Application Testing 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 536 ORA-29283: invalid file operation
此时会有以上报错，原因是日志无法写入ASM当中导致。可以以下两种方式解决：
A.使用NOLOGFILE=YES选项禁用日志。
B.将日志指定到系统的目录。
2.测试NOLOGFILE=YES 成功完成备份
[oracle@sam1 ~]$ expdp system/oracle directory=databk dumpfile=all.dmp full=y NOLOGFILE=YES Export: Release 11.2.0.3.0 - Production on Mon Feb 24 01:22:35 2020 Copyright (c) 1982, 2011, Oracle and/or its affiliates.

3.测试将log写到其他位置 成功完成备份
需要建立一个放log的directory
SYS@PROD1 > create directory logdump as '/home/oracle'; Directory created. [oracle@sam1 ~]$ expdp system/oracle directory=databk dumpfile=scott.dmp schemas=scott logfile=logdump:expdp_scott.log Export: Release 11.2.0.3.0 - Production on Mon Feb 24 04:50:37 2020 Copyright (c) 1982, 2011, Oracle and/or its affiliates.
