本文介绍如何在Oracle数据库中使用ASM磁盘组进行EXPDP逻辑导出操作，并解决了导出过程中日志文件存放的问题。

在客户系统中，由于空间问题，想要将expdp的逻辑导出文件存储到ASM磁盘组中。

经过测试，expdp导出文件完全可以放在ASM磁盘组中，但是日志文件需要放在文件系统上。

首先建立磁盘组中的Directory：

SQL> create or replace directory obak as '+ORADATA/obak';

Directory created.

手工创建目录：

[oracle@oracle ~]$ export ORACLE_SID=+ASM1
[oracle@oracle ~]$ asmcmd
ASMCMD> ls
ORADATA/
RECOVER/
ASMCMD> cd ORADATA
ASMCMD> ls
ORADB/
ASMCMD> mkdir obak
ASMCMD> ls
ORADB/
obak/
ASMCMD> exit

如果直接执行导出，会出现错误：

[oracle@oracledb3 ~]$ expdp eygle/eygle DUMPFILE=eygle.dmp DIRECTORY=OBAK CONTENT=METADATA_ONLY

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

此时需要找到一个文件系统的路径：

SQL> select directory_name, directory_path from dba_directories;

DIRECTORY_NAME
------------------------------
DIRECTORY_PATH
---------------------------------------------------------------------------------------------------
DATA_PUMP_DIR
/opt/app/oracle/product/10.2.0/db_1/rdbms/log/

OBAK
+ORADATA/obak

现在为LOGFILE指定独立的路径，即可导出成功：

[oracle@oracle ~]$ expdp eygle/eygleDUMPFILE=eygle.dmp DIRECTORY=OBAK CONTENT=METADATA_ONLY logfile=DATA_PUMP_DIR:expdp01.log
