title: Opposite of Oracle "ALTER SYSTEM SET" Command
body: <p>I'm looking at some code and I see that someone is writing the following pl/sql.</p>
  
  <pre><code>alter system set smtp_out_server = '123.345.134.123';
  </code></pre>
  
  <p>Since this is the mutator (setter), what's the accessor (getter) of this command?</p>
  
  <p>SELECT what from where to view the SMTP_OUT_SERVER setting?</p>
  
  <p>Thanks,</p>
  
  <p>mj</p>
