title: ORA-02069 global_names parameter must be set to TRUE for this operation
body: <p>I've searched a couple of solutions. One of them is the following:</p>
  
  <p><strong>Cause</strong>
  A remote mapping of the statement is required but cannot be achieved because global_names should be set to TRUE for it to be achieved</p>
  
  <p><strong>Action</strong>
  Issue alter session set global_names = true if possible</p>
  
  <p>But I don't understand why should I need to set global_names parameter...Why does remote mapping use global_names parameter? Please,can you explain me?</p>
  
  <p>P.S I know that setting global_names parameter will arise global naming rules,that the database link name must be the same as the remote database name..And also it appends domain name to the database name like &lt;DB_NAME&gt;.&lt;DB_DOMAIN&gt; what else?</p>
