title: Launching a certain Oracle DB instance
body: <p>I have an Oracle database called A and a database called B on the same server node. There are two init.ora files for both of them. When I command <code>startup</code> in SQLPlus, the following error appears:</p>
  <pre><code>ORA-01103: database name 'B' in control file is not 'A'
  </code></pre>
  <p>I cannot delete B's init-file. How do I make it launch A database? Is there any key for startup to target a certain init-file?</p>
