這篇文章主要介紹“怎么將Expdp備份數(shù)據(jù)轉(zhuǎn)到ASM中”,在日常操作中,相信很多人在怎么將Expdp備份數(shù)據(jù)轉(zhuǎn)到ASM中問(wèn)題上存在疑惑,小編查閱了各式資料,整理出簡(jiǎn)單好用的操作方法,希望對(duì)大家解答”怎么將Expdp備份數(shù)據(jù)轉(zhuǎn)到ASM中”的疑惑有所幫助!接下來(lái),請(qǐng)跟著小編一起來(lái)學(xué)習(xí)吧!
一、問(wèn)題描述
需求要使用expdp備份數(shù)據(jù),檢查系統(tǒng)空間很小,不夠放備份文件。直接給系統(tǒng)加空間不就得了,可是這樣一來(lái)就要耽誤時(shí)間,還要聯(lián)系一大堆人員。此時(shí)ASM空間是很充足的,可不可以使用呢。接著就有以下的操作了。
二、實(shí)驗(yàn)
1.數(shù)據(jù)庫(kù)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
此時(shí)會(huì)有以上報(bào)錯(cuò),原因是日志無(wú)法寫入ASM當(dāng)中導(dǎo)致??梢砸韵聝煞N方式解決:
A.使用NOLOGFILE=YES選項(xiàng)禁用日志。
B.將日志指定到系統(tǒng)的目錄。
2.測(cè)試NOLOGFILE=YES 成功完成備份
[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.測(cè)試將log寫到其他位置 成功完成備份
需要建立一個(gè)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.
