Export Oracle Database Schema Without Data

Export Oracle Database Schema Without Data

Using Oracle Data Pump Utility

The Oracle Data Pump utility can export metadata only with the metadata_only flag. This process necessitates the creation of a new database instance, inclusive of all necessary logs and structures.

Using RMAN for Database Structure

RMAN is utilized for backing up entire databases but is not the tool for exporting schema without data.

Using dbms_metadata for Schema DDL

The dbms_metadata package is capable of exporting an entire schema's DDL, as well as the DDL of tablespaces, to extract the schema structure without the data.

Oracle Database Cloud Schema Service

The Oracle Database Cloud Schema Service facilitates the export of database schemas without data. The process supports secure FTP and cloud storage container methods for exporting.

Cloud Storage and Secure FTP

Oracle Storage Cloud Service can be employed to store the schema export in a cloud container, with the exported schema files being downloadable for two days post-initiation. Secure FTP remains an option for customers with previous Schema Service purchases.

Export Limitations

Note that the Schema Service limits to a maximum of 10 data export requests and does not include data unless specifically requested by selecting Include Data—which should be avoided for a metadata-only export.
