A table mode export is specified using the
TABLES parameter. In table mode, only a specified set of tables, partitions, and their dependent objects are unloaded. Any object required to create the table, such as the owning schema, or types for columns, must already exist.
If you specify the
TRANSPORTABLE=ALWAYS parameter with the
TABLES parameter, then only object metadata is unloaded. To move the actual data, you copy the data files to the target database. This results in quicker export times. If you are moving data files between releases or platforms, then the data files may need to be processed by Oracle Recovery Manager (RMAN).
You must have the
DATAPUMP_EXP_FULL_DATABASE role to specify tables that are not in your own schema. Note that type definitions for columns are not exported in table mode. It is expected that the type definitions already exist in the target instance at import time. Also, as in schema exports, cross-schema references are not exported.
To recover tables and table partitions, you can also use RMAN backups and the RMAN
TABLE command. During this process, RMAN creates (and optionally imports) a Data Pump export dump file that contains the recovered objects. For more on this topic, see Oracle Database Backup and Recovery User's Guide.
