Data pump

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.

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.
