title: Oracle DB ORA-26804: Apply xstream is disabled
body: <p>I'm connecting to Oracle DB through a XStream Out Server and I'm getting this error after a minute or two attaching:</p>
  
  <pre><code>ORA-26804: Apply "XSTREAM_OUT1" is disabled.
  ORA-31020: The operation is not allowed, Reason: not in a valid apply process
  </code></pre>
  
  <p>What is causing this error? I can see my service is attached to the XStream Out Server by checking the DB with this query:</p>
  
  <pre><code>select CLIENT_NAME, CLIENT_STATUS from dba_capture
  </code></pre>
