How To Extract Datapump File From ASM Diskgroup To Local Filesystem?

(Doc ID 566941.1)



适用于：

Oracle Database - Enterprise Edition - Version 11.1.0.6 to 11.1.0.7 [Release 11.1]

目标：

从11.1.0.6開始， asmcmd 提供了cp命令，该cp命令跟os上的cp命令类似。

你能够使用asmcmd cp命令 copy 出asm磁盘组中的全部文件。



解决方式：

举例：

1）在asm实例中建立一个directory

SQL> show parameter instance_name



NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------

instance_name                        string      +ASM



SQL> alter diskgroup FRA add directory '+FRA/dumpsets';



Diskgroup altered.



2）在数据库实例中建立一个directory--用于存放dmp文件

SQL>  show parameter instance_name



NAME                                 TYPE        VALUE

------------------------------------ ----------- ------------------------------  

instance_name                        string      DB11G



SQL> create directory dumpsets as '+FRA/dumpsets';



Directory created.



3）在os上建立一个directory并在database 实例中。为此os directory 建立 db中的directory。该 os directory用于存放导出产生的logfile



SQL> ! mkdir /home/oracle/dumpsets



SQL> !ls -ld /home/oracle/dumpsets

drwxr-xr-x  2 oracle oinstall 4096 May  7 10:20 /home/oracle/dumpsets



SQL> create directory logfile_dest as '/home/oracle/dumpsets';



Directory created.





4）运行expdp导出数据

expdp  userid=system/storage01 directory='DUMPSETS' dumpfile=expdp_5_5.dat job_name=full_export logfile=logfile_dest:exp5_5.log

******************************************************************************

Dump file set for SYSTEM.FULL_EXPORT is:

  +FRA/dumpsets/expdp_5_5.dat





5）dmp文件被创建在了+FRA/dumpsets/下。



ASMCMD> ls -l  +FRA/dumpsets/expdp_5_5.dat

Type     Redund  Striped  Time             Sys  Name

                                           N    expdp_5_5.dat => +FRA/DB11G/DUMPSET/SYSTEMFULL_EXPORT_71029_1.303.654085391


                                           

6）将此dmp文件从asm 磁盘组中复制到os 的directory中。

ASMCMD> pwd  

+fra/dumpsets

ASMCMD> ls

expdp_5_5.dat

ASMCMD>  cp expdp_5_5.dat /home/oracle/dumpsets/expdp_5_5.dat

source +fra/dumpsets/expdp_5_5.dat

target /home/oracle/dumpsets/expdp_5_5.dat

copying file(s)...

file, /home/oracle/dumpsets/expdp_5_5.dat, copy committed.

ASMCMD> exit

$> ls -l /home/oracle/dumpsets/expdp_5_5.dat
