title: Migrate MySQL database to Oracle 11g with SQL Developer 3
body: <p>I try to migrate a sample database from mysql to Oracle 11g using SQL developer. I go through some online tutorial and follow each steps but I don't know why there is no data show up in the target database.</p>
  
  <p>Here is what I did:</p>
  
  <ol>
  <li><p>Connect to MySQL(connection name "MySQL") using SQL Developer with JConnector, log on as root.</p></li>
  <li><p>Create a empty schema for "Repository" during migration named "TEMPBUFFER"</p></li>
  <li><p>Create a target schema for holding the data in Oracle, named "DEVELOPER"</p></li>
  <li><p>Follow migration wizard:</p></li>
  </ol>
  
  <blockquote>
    <p>Migration Repository = TEMPBUFFER<br/>
    Third party database for migration = MySQL<br/>
    Target schema in Oracle = DEVELOPER<br/>
    Only one database called "classmodels" is chosen to be immigrated from MySQL</p>
  </blockquote>
  
  <p>So here are my questions:</p>
  
  <ol>
  <li><p>On top of everything, why there is no table/data show up on DEVELOPER schema, how to fix it?</p></li>
  <li><p>What is a Migration Repository and why we need it? It seems hold a few tables with config information, so is it very common we should use the target schema as Migration Repository?</p></li>
  </ol>
  
  <p>Thanks in advance.</p>
