Managing AtScale Database Instances

AtScale uses a PostgreSQL database instance internally to manage communications between the AtScale services. There might be occasions when you need to start, stop, restart, back up, restore, or roll back a database instance. You might also want to delete old log files to reclaim disk space.

This section describes how to work with AtScale database instances. It covers these topics. Note that some topics apply only to Clustered AtScale instances.

• Starting, Stopping, and Restarting AtScale Database Instances
• Backing Up and Restoring AtScale Database Instances
• Rolling Back AtScale Instances
• Deleting Old Database Log Files
• For AtScale Clusters Only: Manually Promoting Standby Instances to Master Instances
• For AtScale Clusters Only: Returning a Failed AtScale Database Instance to an AtScale Cluster
• For AtScale Clusters Only: Switching the Master AtScale Database Instance to a Different Node
