When the INCLUDE parameter is used, only those objects specified by it will be included in the export/import. The INCLUDE and EXCLUDE parameters can be used to limit the export/import to specific objects. That database user performing the export will need DATAPUMP_EXP_FULL_DATABASE role, and the user performing the import will need the DATAPUMP_IMP_FULL_DATABASE role. Impdp full=Y directory=TEST_DIR dumpfile=DB10G.dmp logfile=impdpDB10G.logįor an example output file see expdpDB10G.log. The following is an example of theĮxpdp full=Y directory=TEST_DIR dumpfile=DB10G.dmp logfile=expdpDB10G.log
The FULL parameter indicates that a complete database export is required. Impdp schemas=SCOTT directory=TEST_DIR dumpfile=SCOTT.dmp logfile=impdpSCOTT.logįor example output files see expdpSCOTT.log and impdpSCOTT.log. The following is an example of the schema export and import syntax.Įxpdp schemas=SCOTT directory=TEST_DIR dumpfile=SCOTT.dmp logfile=expdpSCOTT.log The OWNER parameter of exp has been replaced by the SCHEMAS parameter which is used to specify the schemas to be exported. The TABLE_EXISTS_ACTION=APPEND parameter allows data to be imported into existing tables.
Impdp tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=impdpEMP_DEPT.logįor example output files see expdpEMP_DEPT.log and impdpEMP_DEPT.log. The following is an example of the table export and import syntax.Įxpdp tables=EMP,DEPT directory=TEST_DIR dumpfile=EMP_DEPT.dmp logfile=expdpEMP_DEPT.log The TABLES parameter is used to specify the tables that are to be exported. It does not write to the local file system on your client PC. GRANT READ, WRITE ON DIRECTORY test_dir TO scott Įxisting directories can be queried using the ALL_DIRECTORIES view.ĭata Pump is a server-based technology, so it typically deals with directory objects pointing to physical directories on the database server. The directory object is only a pointer to a physical directory, creating it does not actually create the physical directory on the file system of the database server.ĪLTER USER scott IDENTIFIED BY tiger ACCOUNT UNLOCK ĬREATE OR REPLACE DIRECTORY test_dir AS '/u01/app/oracle/oradata/' Oracle Cloud : Autonomous Data Warehouse (ADW) - Import Data from an Object Store (impdp)įor the examples to work we must first unlock the SCOTT account and create a directory object it can access.SQL Developer 3.1 Data Pump Wizards (expdp, impdp).Data Pump (expdp, impdp) : All Articles.External Tables (Unloading/Loading Data Using External Tables).
New features are broken out into separate articles, but the help section at the bottom is up to date with the latest versions. This article was originally written against Oracle 10g, but the information is still relevant up to and including the latest versions of Oracle. In addition to basic import and export functionality data pump provides a PL/SQL API and support for external tables. Oracle Data Pump is a newer, faster and more flexible alternative to the "exp" and "imp" utilities used in previous Oracle versions.
