title: wso2 esb - skip dbreport mediator when DB connection failed
body: <p>I created a datasource for dbreport mediator to log into MSSQL database. i want to skip this mediator when database connection failure occurs. I have used "Validation Query" in datasource, but it doesn't solve the problem. 
  When a database connection exception occurs, fault sequence executes.
  Is there any solution?</p>
  
  <p>thanks in advance</p>
