title: Oracle 11g. Unable to import dump files, even though schema is created
body: <p>I have created a user in Oracle 11gR2, using the following script</p>
  
  <pre><code>create user          cata
  identified by        cata
  default   tablespace tbs
  temporary tablespace temp;
  
  grant DBA to cata;
  </code></pre>
  
  <p>After trying to import a dump file using the command </p>
  
  <pre><code>impdp system/password@ORCL11 schemas=cata dumpfile=cata.dmp logfile=log.txt
  </code></pre>
  
  <p>i'm getting the following error</p>
  
  <p><b> ORA-39002: invalid operation
  ORA-39165: Schema ATGDB_CATA was not found. </b> </p>
  
  <p>Surprisingly, when i try to export a dump from the same schema, i'm able to do that. So, if the schema was not created properly then i should not be able to export the dump file as well, right ?</p>
  
  <p>I have also checked in dba_users &amp; the schema is created.  Is there anything else that i can do which could resolve this problem</p>
