title: oracle data pump import ORA-39002 with ORA-39070, ORA-29283 and others on Windows 10
body: <p>I am using data pump to perform an import on 4 .dmp files and keep on receiving the set of errors as below: </p>
  
  <pre><code>ORA-39002: invalid operation
  ORA-39070: Unable to open the log file.
  ORA-29283: invalid file operation
  ORA-06512: at "SYS.UTL_FILE", line 536
  ORA-29283: invalid file operation
  </code></pre>
  
  <p>I am new to oracle and cannot find a helpful solution.</p>
  
  <p>I am performing the import as in <a href="https://oracle-base.com/articles/10g/oracle-data-pump-10g" rel="noreferrer">here</a>, although I'm using oracle 12c.</p>
  
  <p>The command I run in the windows command like looks like this:</p>
  
  <pre><code>impdp user/pass@db_name directory=DUMP_DIR dimpfile="file_name.dmp" schemas=schema_name content=all parallel=4
  </code></pre>
  
  <p>DUMP_DIR is created in oracle and appropriate privs were granted.</p>
  
  <p>I also ran this command with </p>
  
  <pre><code>... logfile=file_name.log
  </code></pre>
  
  <p>added at the end but I'm not sure if the log file was created or where it was saved.</p>
  
  <p>I have found <a href="http://www.dba-oracle.com/t_ora_39002_ora_39070_ora_29283.htm" rel="noreferrer">this</a> - it's about exactly the same set of errors but on export and on linux. At the end of the answer there's a sentence 'If we are on a Windows machine, then we need to make sure that both the listener and the database have been started with the exact same username.' Is this useful in case of import? If yes - what does it mean exactly?</p>
