body: <p>Hi im trying to create clone_link between two ora19 databases due to cloning PDB databases</p>
  
  <p>both DBs have created user like:</p>
  
  <pre><code>CREATE USER c##remote_clone_user IDENTIFIED BY remote_clone_user CONTAINER=ALL;
  GRANT CREATE SESSION, CREATE PLUGGABLE DATABASE TO c##remote_clone_user CONTAINER=ALL;
  </code></pre>
  
  <p>i want to copy PDB from DB2 to DB1 so i closed wanted PDB on DB2 and opened for reading:</p>
  
  <pre><code>alter pluggable database testpdb close;
  alter pluggable database testpdb open read only;
  </code></pre>
  
  <p>from DB1 have created clone_link and tried to copy PDB (tns testpdb connection is set to DB2)</p>
  
  <pre><code>--db link to database we want to copy
  create database link clone_link
      connect to C##remote_clone_user identified by remote_clone_user using 'testpdb';
  
  -- clone from DB2 to DB1  
  create pluggable database testpdb from testpdb@clone_link
      file_name_convert = ('/u01/app/oracle/oradata/', '/testpdb/');
  </code></pre>
  
  <p>but im getting error :</p>
