Persisting MMC Data On External Databases
By default, the Mule Management Console stores its persistent data on an embedded database on the local host. In this scenario, a catastrophic failure of the host would cause the loss of all data.

There are two kinds of data that MMC can store on external databases:
Environment data, such as created alerts, deployments, dashboard portlets configuration
Transaction data (Business Events)
You can configure MMC to store its data on the following database servers:
