oracle11g expdp报错 ORA-06512: at "SYS.UTL_FILE", line 536
1，在linux命令行里面expdp导出数据报错：
[oracle@ocrm ~]$ expdp \'crm_user/crm010209\' directory=DIR_DUMPtables=bis_store dumpfile=bis_store_wubo_bak_$(date +%Y%m%d)_02.dmp

[oracle@ocrm ~]$
分析，可能是导出的directory无效，需要重新设置下。
2，查看directory是否存在
SQL> select * from dba_directories whereDIRECTORY_NAME='DIR_DUMP';
OWNER DIRECTORY_NAME
------------------------------------------------------------
DIRECTORY_PATH
--------------------------------------------------------------------------------
SYS DIR_DUMP
/oracle/expdir/

[oracle@ocrm ~]$ ll /oracle/expdir/
ls: cannot access /oracle/expdir/: No suchfile or directory
[oracle@ocrm ~]$
果然这个目录无效，看了需要重建目录了。
3，重建目录
[oracle@ocrm ~]$ mkdir -p /oracle/expdir/
[oracle@ocrm ~]$
4，再重新导出成功
[oracle@ocrm ~]$ expdp \'crm_user/crm010209\' directory=DIR_DUMPtables=bis_store dumpfile=bis_store_wubo_bak_$(date +%Y%m%d)_02.dmp
