[rabbitmq-discuss] How does Messages will be persisted in RabbitMQ?

[Rajasekhar P]

I have added RABBITMQ_BASE, RABBITMQ_MNESIA_DIR and RABBITMQ_MNESIA_BASE in
envt var's. But, the folder RABBITMQ_MNESIA_DIR folder is not updated even
after restarting the server. Do I need to setup any other things?
