Using impdp to Transfer Data on Linux Systems（impdplinux）

Data transfer is an important part of computing. Data transfer on Linux systems relies on the Linux utility impdp. Impdp is the data pump import utility which Oracle developed to help users import and export data from their databases.

The first step in using impdp is to create a directory which is the location in Oracle where you will store the data dump files. Create the directory by typing the following command:

SQL> create directory my_dir as ‘/data/dumps’;

Next, you must create a tablespace to store the imported data. This can be done by executing the following command:

SQL> create tablespace data_transfer blocksize 8192;

Next, you will need to set the environment for impdp to use. This is done by executing the following command:

$ export ORACLE_SID=YOUR_SID

Next, you will need to log in as the suitable user and execute the command below to invoke impdp. Make sure to replace the name of the directory, dump_file, username and tablespace with the appropriate values.

$ impdp system/password@your_sid directory=my_dir dumpfile=dump_file.dmp remap_schema=old_user:new_user tablespaces=data_transfer

This will start the import process and the data will be transferred. The impdp utility will then import the data into the tablespace and create an audit report about the process.

By using impdp, you can easily promote data from one database to another on a Linux system. It is an important tool for data transfers and is especially useful when the schemas are different between the databases or when you want to transfer bulk amounts of data.

Impdp is a great tool and one that can help make data transfers on Linux systems a lot easier. Coupled with the other utilities available on Linux systems, it is a great way to make data transfers much more efficient.
