IT30616: MQTTPUBLISH NODE DISCONNECTS AFTER EVERY MESSAGE WHEN USING LOCALENVIRONMENT OVERRIDES.

APAR status

• Closed as program error.

Error description

• The MQTT Publish node will always disconnect the client when
  local environment overrides are being used to specify the
  connection URL at runtime for example:
  .
  SET OutputLocalEnvironment.Destination.MQTT.Output.URL =
  'tcp://localhost:1883';
  .
  The client should only be disconnected if the URL being used is
  different to the one currently being used.

Problem conclusion

• The MQTTPublish node now only disconnects if the URL does not
  match the one currently associated with the current connection.
  Additionally to provide further fault tolerance to intermittent
  connection issues the MQTTPublish node will now attempt a single
  inline retry when it receives a broken connection error from an
  attempt to publish a message.
