+On **target** database create a directory and an user for database link:
+```sql
+create directory DIR_DEST as '/mnt/yavin4/tmp/_oracle_/dir_dest';
+create user USER_DBLINK identified  by *****;
+grant create session to USER_DBLINK;
+grant read,write on directory DIR_DEST to user_dblink;
+```
+
+On **source** database create a directory and a database link:
+```sql
+create directory DIR_SOURCE as '/mnt/yavin4/tmp/_oracle_/dir_source';
+create database link REMOTE_DB connect to USER_DBLINK identified by ***** using 'taris/WEDGEPRD';
+select * from dual@REMOTE_DB;
+```
+
+Use `DBMS_FILE_TRANSFER` from soure database to copy a single file from source directory to target directory:
+```sql
+BEGIN
+  DBMS_FILE_TRANSFER.put_file(
+   source_directory_object      => 'DIR_SOURCE',
+   source_file_name             => 'Full_GREEDOPRD_01.dmp',
+   destination_directory_object => 'DIR_DEST',
+   destination_file_name        => 'Full_GREEDOPRD_01.dmp',
+   destination_database         => 'REMOTE_DB');
+END;
+/
+```
+
+`DBMS_FILE_TRANSFER` don't have a **parallel** option, but we can run parallel transfers using `DBMS_SCHEDULER` jobs:
+```sql
+create or replace procedure FILECOPY1 as 
+BEGIN
+  DBMS_FILE_TRANSFER.put_file(
+   source_directory_object      => 'DIR_SOURCE',
+   source_file_name             => 'Full_GREEDOPRD_01.dmp',
+   destination_directory_object => 'DIR_DEST',
+   destination_file_name        => 'Full_GREEDOPRD_01.dmp',
+   destination_database         => 'REMOTE_DB');
+END;
+/
+
+create or replace procedure FILECOPY2 as 
+BEGIN
+  DBMS_FILE_TRANSFER.put_file(
+   source_directory_object      => 'DIR_SOURCE',

+   destination_directory_object => 'DIR_DEST',
+   destination_file_name        => 'Full_GREEDOPRD_02.dmp',
