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

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

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
