Deep Data Mining Blog: Dump the Oracle Schema

Sunday, December 07, 2014

We can use Oracle data pump utility to dump the whole schema or selected database objects. The following command dump the schema.

$ expdp prod/XXXX schemas=prod directory=ORA_DATA_EBS_BK dumpfile=prod_bk.dmp logfile=prod_bk.log

The above command creates two files under directory ORA_DATA_EBS_BK.

-rw-r--r-- 1 oracle dba       5129 Dec  7 08:07 prod_bk.log
-rw-r----- 1 oracle dba    2650112 Dec  7 08:07 prod_bk.dmp

We can import them back into a database using impdp command.

$ impdp prod/XXXX schemas=prod directory=ORA_DATA_EBS_BK dumpfile=prod_bk.dmp
