title: Running multiple SCDF(Local server not CF based) pointing to single DB for HA
body: <p>We are using SCDF 1.2.3.RELEASE (Local Server) for calling different task created using spring cloud task 1.2.2.RELEASE. We want to run the multiple instances of SCDF in our environment so that we can achieve high availability and (Load Balancing). </p>
  
  <p>want to confirm that when we trigger a task on one of the SCDF using its ReST API, is there any chance that both SCDF the instances may start running the task and create ambiguity because both SCDF will be pointing to same DB.</p>
  
  <p>Unfortunately running SCDF on cloud like CF, Mesos or Kubernetes is not an option for us.</p>
  
  <p>We tried running 2 SCDF pointing to the same DB and submitting task request. We did not get any error and task ran correctly as well. But maybe we were just lucky to NOT get an error. We want to be utterly sure that Execution ID being generated will not get executed at more than one SCDF server.</p>
