dbms_datapump metadata_remap tips

Oracle Database Tips by Donald BurlesonJuly 21, 2015

I need to find, from a Data Pump export (expdp) dump file, the value of "fromuser" as it existed during the export.  I need it because I use the schema owner as an argument for metadata_remap proc in dbms_datapump.

Answer: (By Kamran Agayev A.)  Data Pump export represents the data in XML format, so you should be able to see everything in the export file.

There's no fromuser parameter in Data Pump and it's been changed to schemas parameter in Data Pump.

By defining this parameter you specify the schema owner from which you want to export all objects.

To find out the original schema referenced in the Data Pump export dump file, you can use sqlfile clause of the impdp which creates set of sql commands using dump file. From that file you can get the schema name in the create table commands.

Also see my Data Pump sqlfile parameter tips.
