today’s guide is designed to help you when you receive an error code while importing a dump file into Oracle. The Oracle Disposal file must be imported into the Oracle schema part using the this impdp special command. Use the following import command for the dump file. SPEND_DBA: A regular database user agrees to export and import any existing schema. In this case, the account/password name is SPEND_DBA / SPEND_DBA .
What Is A Data Pump Import?
How import data Pump export dump file?
Oracle Data Pump is a fast throughput utility provided by Oracle.Create a directory in one databaseX.grant access rights to the directory of subjects.View directory information.Export table levels.Import a table in which the initial laser target is identical in the diagram.table imports an additional schema.
Data Pump (hereinafter referred to as simply import) is the ability to load an export dataset into a dump on a target system. A set of dump files is built incrementally from one or more disk PCs containing tabular data, database part metadata, and control information. The data is written in a binary proprietary format. During a utility import operation, the Data Pump Import type uses the same files to find each database principal in the dump file set.
Import should also be used directly from the root database documentation without an intermediate dump in a hundred target databases. This allows the export and import functions to run simultaneously, which reduces the overall time spent. This is called import matching.
The Data import allows the pump client to specify whether the pump shouldAllowing actually a subset to move personal data and metadata from a dump tool or a set of database applications (in the case of a network import), as determined by the import tools. This can be done with document filters and metadata filters implemented with import commands. See the Filtering section during the import process.
To see some of the products and the different uses of imports, in particular, read the Pump Data Import usage examples from.
Data Pump (called an import with a viewimpdp command) is a new utility in oracle 10.gram database. Although its functionality and settings are the same as those of the First Time Import utility (imp), these are completely isolated utilities and their files are incompatible.

Retrieving Pump Data
The data import trick called pump uses the impdp command. Import Properties are determined by the import options you specify. These parameters can be seen in the command line. line, and the file in the parameters.

How import single table from dump file using Impdp?
TRUNCATE => Truncates when necessary when importing the table, and therefore the data from. dispose of.REPLACE => will probably first replace the table with a dump and definitions, then import the data.APPEND very May => good to add data and leave existing data.

Call import but not likeSYSDBA well, except, of course, at the request of Oracle Plumbing Support. Usedsysdba internally has additional specialized functions; His behavior is still not the same as that of abusive users.
Note that if you are actually doing a Data Pump import on a table or tablespace that was created with theWITHOUT using REGISTRATION enabled, the update log file can still be created. The repetition generated all over the place in such a case is usually associated with basic spatial recursion transactions, changes to the lookup dictionary, and index maintenance to obtain indexes on the table being logged.
Data Pump tasks in a Real Application Clusters (RAC) environment may not start or restart the instance if the Data Pump tasks are running on your non-RAC instances. [Addedbut this is an email note to Steve Dipirro dated 08/30/04.]
Data Import Interfaces Can Pump
You interact with importing pump data using the command line, parameter file, or interactive best mode commands.
Command Line Interface: Allows you to set import options from the command line itself. For a detailed description of the options available in the command line interface, see the “Options” section in the “Available command line mode for import” section.
Parameter file interface: whether it is possible to specify command line recommendations in the parameter file. The only exception is the PARFILE parameter, mainly because parameter files cannot be nested. The use of parameter files is recommended when using coefficients whose values ​​require quotes. See Using quotes in our pump command line data.
Interactive command interface: stops the transport to the terminal and displays the current import prompt from which you would likeYou will be entering certain commands related to interactive command mode. This mode is activated by pressing Ctrl + C during the import process initiated from the command line interface or from your current settings file interface. However, interactive command mode is also activated when you join a running task or if it has stopped you.
For a complete description of the commands available in interactive command mode, see Commands Available in Interactive Command Mode Import.
Data Pump Import Modes
One of the most important parameters in the proper import process is the warning, which largely determines what exactly is imported. specified The mode uses the system source, dump file set, and/or other database if NETWORK_LINK.

How do I import and export an Oracle Database?
In SQL Developer “Tools”, click then click “Export Database”.Accept the defaults for the main page options, except for source/destination, as they are accepted:Press “Next.On the “Types to export” page, uncheck all, “Only select tables” (because you only need to export data from this table).
If our source import operation is a dump statement, an entry specifying the pass mode is not required. If the mode is no, the import attempts to download the complete dump file in the same way that the export process was started.Mode
