Export Modes	Mode Description Full Use the FULL parameter: Exports the entire database is unloaded. EXP_FULL_DATABASE role required. Schema Use the SCHEMAS parameter: The default export mode. If you have the EXP_FULL_DATABASE role, then you can specify a list of schemas and optionally include the schema definitions themselves, as well as system privilege grants to those schemas. If you do not have the EXP_FULL_DATABASE role, you can export only your own schema. Table Use the TABLES parameter. A specified set of tables, partitions, and their dependent objects are unloaded. You must have the EXP_FULL_DATABASE role to specify tables that are not in your own schema. All specified tables must reside in a single 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. Tablespace Use the TABLESPACES parameter. Only tables contained in a specified set of tablespaces are unloaded. If a table is unloaded, its data, metadata, and dependent objects are also unloaded. In tablespace mode, if any part of a table resides in the specified set, then that table and all of its dependent objects are exported. Privileged users get all tables. Nonprivileged users get only the tables in their own schemas. Transportable Tablespace Use the TRANSPORT_TABLESPACES parameter. In transportable tablespace mode, only the metadata for tables, and dependent objects, within a specified set of tablespaces are unloaded. EXP_FULL_DATABASE role required. Degree of parallelism must = 1. Legacy Data Pump enters legacy mode once it determines a parameter unique to original Export is present, either on the command line or in a script. As Data Pump processes the parameter, the analogous Data Pump Export parameter is displayed.
Import Modes	Mode Description Full A full import is specified using the FULL parameter. In full import mode, the entire content of the source (dump file set or another database) is loaded into the target database. This is the default for file-based imports. You must have the DATAPUMP_IMP_FULL_DATABASE role if the source is another database. Cross-schema references are not imported for non-privileged users. For example, a trigger defined on a table within the importing user's schema, but residing in another user's schema, is not imported. Schema Schema import is specified using the SCHEMAS parameter. In a schema import, only objects owned by the specified schemas are loaded. The source can be a full, table, tablespace, or schema-mode export dump file set or another database. you have the DATAPUMP_IMP_FULL_DATABASE role, then a list of schemas can be specified and the schemas themselves (including system privilege grants) are created in the database in addition to the objects contained within those schemas. Cross-schema references are not imported for non-privileged users unless the other schema is remapped to the current schema. For example, a trigger defined on a table within the importing user's schema, but residing in another user's schema, is not imported. Table Table-mode import is specified using the TABLES parameter. In table mode, only the specified set of tables, partitions, and their dependent objects are loaded. The source can be a full, schema, tablespace, or table-mode export dump file set or another database. You must have the DATAPUMP_IMP_FULL_DATABASE role to specify tables that are not in your own schema. You can use the transportable option during a table-mode import by specifying the TRANPORTABLE=ALWAYS parameter with the TABLES parameter. This requires use of the NETWORK_LINK parameter, as well. Tablespace Tablespace-mode import is specified using the TABLESPACES parameter. In tablespace mode, all objects contained within the specified set of tablespaces are loaded, along with the dependent objects. The source can be a full, schema, tablespace, or table-mode export dump file set or another database. For unprivileged users, objects not remapped to the current schema will not be processed. Transportable Tablespace Transportable tablespace import is specified using the TRANSPORT_TABLESPACES parameter. In transportable tablespace mode, the metadata from a transportable tablespace export dump file set or from another database is loaded. The datafiles, specified by the TRANSPORT_DATAFILES parameter, must be made available from the source system for use in the target database, typically by copying them over to the target system. Encrypted columns are not supported in transportable tablespace mode. This mode requires the DATAPUMP_IMP_FULL_DATABASE role. In transportable tablespace mode, only the metadata for tables, and dependent objects, within a specified set of tablespaces are unloaded. EXP_FULL_DATABASE role required.Degree of parallelism must = 1. Legacy Data Pump enters legacy mode once it determines a parameter unique to original Import is present, either on the command line or in a script. As Data Pump processes the parameter, the analogous Data Pump Import parameter is displayed.
Exporting Schemas
Demo Setup	conn / as sysdba desc dba_directories col owner format a10 col directory_path format a70 SELECT * FROM dba_directories; CREATE OR REPLACE DIRECTORY data_pump_dir AS 'c:temp'; -- default is $ORACLE_BASE/admin/<database_name>/dpdump GRANT export full database TO uwclass; Note: Verify that the environment variables ORACLE_HOME and ORACLE_SID are set properly in your shell. If they are not set then you must set them at the command line to proceed.
Basic Export Types
Note: After each export, SELECT table_name FROM user_tables in the schema that ran the export, in the following examples, uwclass or abc. You will find tables with names such as SYS_EXPORT_FULL_01 and SYS_EXPORT_SCHEMA_01. Examine their contents

Legacy Mode Mappings	Legacy Export Cmd How Handled BUFFER This parameter is ignored because Data Pump does not make use of conventional mode. COMPRESS This parameter is ignored. In original Export, the COMPRESS parameter affected how the initial extent was managed. Setting COMPRESS=n caused original Export to use current storage parameters for the initial and next extent. The Data Pump COMPRESSION parameter is used to specify how data is compressed in the dump file, and is not related to the original Export COMPRESS parameter. CONSISTENT Data Pump Export determines the current time and uses FLASHBACK_TIME . CONSTRAINTS If original Export used CONSTRAINTS=n, then Data Pump Export uses EXCLUDE=CONSTRAINTS. The default behavior is to include constraints as part of the export. DIRECT This parameter is ignored. Data Pump automatically chooses the best export method. FEEDBACK The Data Pump STATUS=30 command is used. Note that this is not a direct mapping because the STATUS command returns the status of the export job, as well as the rows being processed. In original Export, feedback was given after a certain number of rows, as specified with the FEEDBACK command. In Data Pump, the status is given every so many seconds, as specified by STATUS. FILE Data Pump attempts to determine the path that was specified or defaulted to for the FILE parameter, and also to determine whether a directory object exists to which the schema has read and write access. GRANTS If original Export used GRANTS=n, then Data Pump uses EXCLUDE=GRANT. If original Export used GRANTS=y, then the parameter is ignored and does not need to be remapped because that is the Data Pump default behavior. INDEXES If original Export used INDEXES=n, then Data Pump uses the EXCLUDE=INDEX parameter. If original Export used INDEXES=y, then Data Pump uses the INCLUDE=INDEX parameter. LOG Data Pump attempts to determine the path that was specified or defaulted to for the LOG parameter, and also to determine whether a directory object exists to which the schema has read and write access. OBJECT_CONSISTENT This parameter is ignored because Data Pump processing ensures that each object is in a consistent state when being exported. OWNER The Data Pump SCHEMAS parameter is used. RECORDLENGTH This parameter is ignored because Data Pump automatically takes care of buffer sizing RESUMABLE This parameter is ignored because Data Pump automatically provides this functionality RESUMABLE_NAME This parameter is ignored because Data Pump automatically provides this functionality RESUMABLE_TIMEOUT This parameter is ignored because Data Pump automatically provides this functionality. ROWS If original Export used ROWS=y, then Data Pump Export uses the CONTENT=ALL parameter. If original Export used ROWS=n, then Data Pump Export uses the CONTENT=METADATA_ONLY parameter. STATISTICS This parameter is ignored because statistics are always saved for tables as part of a Data Pump operation. TABLESPACES If original Export also specified TRANSPORT_TABLESPACE=n, then Data Pump ignores the TABLESPACES parameter. If original Export also specified TRANSPORT_TABLESPACE=y, then Data Pump takes the names listed for the TABLESPACES parameter and uses them. TRANSPORT_TABLESPACE If original Export used TRANSPORT_TABLESPACE=n (the default), then Data Pump uses the TABLESPACES parameter. If original Export used TRANSPORT_TABLESPACE=y, then Data Pump uses the TRANSPORT_TABLESPACES parameter and only the metadata is exported. TRIGGERS If original Export used TRIGGERS=n, then Data Pump Export uses the EXCLUDE=TRIGGER parameter TTS_FULL_CHECK If original Export used TTS_FULL_CHECK=y, then Data Pump uses the TRANSPORT_FULL_CHECK parameter. If original Export used TTS_FULL_CHECK=y, then the parameter is ignored. VOLSIZE It means the location specified for the dump file is a tape device. The Data Pump Export dump file format does not support tape devices. Therefore, this operation terminates with an error.

Legacy Mode Mappings	Legacy Export Cmd How Handled BUFFER This parameter is ignored because Data Pump does not make use of conventional mode. CHARSET This parameter is desupported and will cause the Data Pump Import operation to abort. COMMIT This parameter is ignored. Data Pump Import automatically performs a commit after each table is processed. COMPILE This parameter is ignored. Data Pump Import compiles procedures after they are created. CONSTRAINTS If original Import used CONSTRAINTS=n, then Data Pump Import uses the EXCLUDE=CONSTRAINT parameter. If original Import used CONSTRAINTS=y, the parameter is ignored and does not need to be remapped because that is the Data Pump Import default behavior. DATAFILES The Data Pump Import TRANSPORT_DATAFILES parameter is used. DESTROY If original Import used DESTROY=y, then Data Pump Import uses the REUSE_DATAFILES=y parameter. If original Import used DESTROY=n, the parameter is ignored and does not need to be remapped because that is the Data Pump Import default behavior. FEEDBACK The Data Pump Import STATUS=30 command is used. Note that this is not a direct mapping because the STATUS command returns the status of the import job, as well as the rows being processed. In original Import, feedback was given after a certain number of rows, as specified with the FEEDBACK command. In Data Pump Import, the status is given every so many seconds, as specified by STATUS. FILE Data Pump attempts to determine the path that was specified or defaulted to for the FILE parameter, and also to determine whether a directory object exists to which the schema has read and write access. FILESIZE This parameter is ignored because the information is already contained in the Data Pump dump file set. FROMUSER The Data Pump SCHEMAS parameter is used. If FROMUSER was used without TOUSER also being used, then import schemas that have the IMP_FULL_DATABASE role cause Data Pump Import to attempt to create the schema and then import that schema's objects. Import schemas that do not have the IMP_FULL_DATABASE role can only import their own schema from the dump file set. GRANTS If original Import used GRANTS=n, then Data Pump uses the EXCLUDE=OBJECT_GRANT parameter. If original Import used GRANTS=y, the parameter is ignored and does not need to be remapped because that is the Data Pump Import default behavior. IGNORE If original Import used IGNORE=y, then Data Pump Import uses the TABLE_EXISTS_ACTION=APPEND parameter. This causes the processing of table data to continue. If original Import used IGNORE=n, the parameter is ignored and does not need to be remapped because that is the Data Pump Import default behavior. INDEXES If original Import used INDEXES=n, then Data Pump uses the EXCLUDE=INDEX parameter. If original Import used INDEXES=y, the parameter is ignored and does not need to be remapped because that is the Data Pump default behavior. INDEXFILE fThe Data Pump Import SQLFILE={directory-object:}filename and INCLUDE=INDEX parameters are used. The same method and attempts made when looking for a directory object described for the FILE parameter also take place for the INDEXFILE parameter. If no directory object was specified on the original Import, then Data Pump  uses the directory object specified with the DIRECTORY parameter. LOG Data Pump attempts to determine the path that was specified or defaulted to for the LOG parameter, and also to determine whether a directory object exists to which the schema has read and write access. RECORDLENGTH This parameter is ignored because Data Pump automatically takes care of buffer sizing RESUMABLE This parameter is ignored because Data Pump automatically provides this functionality RESUMABLE_NAME This parameter is ignored because Data Pump automatically provides this functionality RESUMABLE_TIMEOUT This parameter is ignored because Data Pump automatically provides this functionality. ROWS=N If original Import used ROWS=n, then Data Pump uses the CONTENT=METADATA_ONLY parameter. If original Import used ROWS=y, then Data Pump uses the CONTENT=ALL parameter. SHOW If SHOW=y is specified, the Data Pump Import SQLFILE=[directory_object:]file_name parameter is used to write the DDL for the import operation to a file. Only the DDL (not the entire contents of the dump file) is written to the specified file. (Note that the output is not shown on the screen as it was in original Import.) STATISTICS This parameter is ignored because statistics are always saved for tables as part of a Data Pump operation. STREAMS_CONFIGURATION This parameter is ignored because Data Pump Import automatically determines it; it does not need to be specified. STREAMS_INSTANTIATION This parameter is ignored because Data Pump Import automatically determines it; it does not need to be specified. TABLESPACES If original Import also specified TRANSPORT_TABLESPACE=n (the default), then Data Pump ignores the TABLESPACES parameter. If original Import also specified TRANSPORT_TABLESPACE=y, then Data Pump takes the names supplied for this TABLESPACES parameter and applies them to the Data Pump TRANSPORT_TABLESPACES parameter. TOID_NOVALIDATE This parameter is ignored. OIDs are no longer used for type validation. TO_USER The REMAP_SCHEMA parameter is used. There may be more objects imported than with original Import. Data Pump may create the target schema if it does not already exist. TRANSPORT_TABLESPACE If original Import used TRANSPORT_TABLESPACE=n, then Data Pump Import ignores this parameter. TTS_OWNERS This parameter is ignored because this information is automatically stored in the Data Pump dump file set. VOLSIZE When the VOLSIZE parameter is used, it means the location specified for the dump file is a tape device. The Data Pump dump file format does not support tape devices. The operation terminates with an error.
