When data is moved, Data Pump automatically uses either direct path load (or unload) or the external tables mechanism, or a combination of both. When metadata is moved, Data Pump uses functionality provided by the DBMS_METADATA PL/SQL package. The DBMS_METADATA package provides a centralized facility. It is ideal for large databases and data warehousing environments, where high- performance data movement offers significant time savings to database administrators. Data Pump automatically manages multiple, parallel streams of unload and load for maximum throughput. The degree of parallelism can be adjusted. Oracle White Paper— Oracle Data Pump Quick Start. 1. Introduction. Oracle Data Pump is the replacement for the original Export and Import utilities. Available starting in Oracle Database 10g, Oracle Data Pump enables very high-speed movement of data and metadata from one database to another. The Data Pump Export.
Oracle Data Pump (expdp, impdp) in Oracle Database 10g, 11g, 12c. Oracle Data Pump is a newer, faster and more flexible alternative to the "exp" and "imp" utilities used in previous Oracle versions. In addition to basic import and export functionality data pump provides a PL/SQL API and support for external tables. Jul 4, Datapump is a server based bulk data movement infrastructure that supersedes the old import and export utilities. The old export/import tools are still available, but do not support all Oracle 10g, 11g and 12c features. The new utilities are named expdp and impdp. Data Pump Export and Import. Data Pump takes the old export and import utilities one step further, you can have total control over the job running (stop it, pause it, check it, restart it). Data pump is a server side technology and it can transfer large amounts of data very quickly using parallel streams to achieve maximum.
To use the Data Pump export and/or import job, you need to run its binary executable which would be, for export, expdp and for import, impdp. If you just type the expdp command with the switch help=Y, all the options of said binary are shown to you with a brief description of each. The Data Pump export utility provides a. EMS Data Pump for PostgreSQL is an excellent migration tool for converting databases and importing table data from an ADO-compatible source (e.g. MS Access, MS SQL database or any other database with ADO support) to PostgreSQL databases. Easy-to-use wizard application allows you to build the ADO connection. Oracle Data Pump provides a server-side infrastructure for very high-speed loading and unloading of data and metadata to and from the database.
