Error description
Desc: When using the Mqtt nodes the clean session attribute is always set to true, meaning that any messages outstanding for the client are deleted upon connection. This is not always the behaviour that is desired, some use cases require messages to be retained. This APAR adds the environment variable MQSI_MQTT_DONT_CLEAN_SESSION. When this environment variable is set to any value then the nodes will set the clean session flag to false when connecting to Mqtt. A restart of the Integration Node is required for changes to this setting to take effect. Additional Symptom(s) Search Keyword(s):
