You can delete archive log files from Oracle database by following these steps:

  1. Make sure you have a database user identity with SYSDBA or SYSOPER privileges.
  2. You can connect to the database instance using either the SQL*Plus tool or other database management tools.
  3. View the current save path of the archive log files. You can use the following SQL statement to query:
  4. Show the names from the view V$ARCHIVED_LOG.
  5. This command will display the path and name of the current archive log file.
  6. Confirm the archived log files you wish to delete. You can use the following SQL statement to view the files to be deleted:
  7. Switch to a different log file in the system.
  8. This would prompt Oracle to create a new archive log file and mark the current archive log file as eligible for deletion.
  9. Close the database instance. If you are using the SQL*Plus tool, you can execute the following command to shut down the database:
  10. immediately shut down
  11. If you are using a different database management tool, please use the appropriate command to close the database.
  12. Delete archived log files. Use a file management tool at the operating system level, such as Windows Explorer or Unix’s rm command, to delete archived log files.
  13. Please make sure to only delete the archive log files that were confirmed to be deleted in step 3, and not other important database files.
  14. Start the database instance. Use the following command to start the database:
  15. Commence;
  16. This will restart the database, and Oracle will automatically mark any missing archive log files as invalid.

Please note that deleting archive log files may result in the database being unable to recover. Therefore, make sure you understand the associated risks before deleting any archive log files and perform backup and recovery operations if necessary.
