To import a dmp file into an Oracle database, you can follow these steps:

  1. Confirm that Oracle database software has been correctly installed and configured.
  2. Open a command prompt window or terminal, and log in to the database using sysdba privileges. For example, you can use the following command to log in as the sys user:
  3. Log in to sqlplus as the sysdba user.
  4. Create a target user for importing data. For example, you can create a new user, “myuser,” by executing the following command.
  5. Create a user named “myuser” with the password “mypassword” and grant them the “connect” and “resource” privileges.
  6. Exit the sys user and log back in to the newly created user myuser.
  7. Leave
    Log in using myuser/mypassword on SQLPlus.
  8. Import the dmp file using the following command:
  9. Import data using the impdp utility with the specified directory, dump file, and log file.
  10. Remember to replace , , and with the actual names of the directory, dmp file, and log file.
  11. For example, if the directory name is DATA_PUMP_DIR, the dmp file name is mydata, and the log file name is import_log, the command would be as follows:
  12. Start importing the dump file named ‘mydata.dmp’ into the database, using the IMPDP command with the specified directory and log file. Use the credentials ‘myuser’ and ‘mypassword’.
  13. After the import is complete, you can view the import log file to check for any errors or warnings.

These steps will import the data from the dmp file into an Oracle database. Please note that the import process may take some time, depending on the size of the dmp file and your system performance.
