title: Oracle: using impdp from a full DB expdp
body: <p>I’ve got a full Dump of an Database (all schema, system etc...)
  Now I want to import just one schema of this file, is this even possible?</p>
  
  <p>As far I got this command:  </p>
  
  <pre><code>impdp sysadm/sysadm@sysadm schemas=sysadm directory=dp_dir dumpfile=export.dmp logfile=export.log 
  </code></pre>
  
  <p>Would this work?
  The problem is, in this dump file there are schemas that are already used and I can't overwrite them (I can but it would be pain for me to recover them)</p>
  
  <p>thanks for help</p>
