Concurrent Operations on Autonomous Database

Describes the actions that cause Oracle Cloud Infrastructure Console to ask you to confirm pausing or canceling a concurrent operation.

When you initiate certain operations that take some time to complete, including scaling the system, scaling the OCPUs count or storage up or down, or performing a manual backup, these operations do not prevent you from performing other operations. For example, database connections, database operations, and most Autonomous Database actions proceed normally while you scale the system or when a manual backup is in progress. However, certain database lifecycle management actions such as stopping the database have an impact on concurrent long-running operations.

For some actions a confirmation dialog displays to let you know when a concurrent operation is active. This allows you to proceed or to cancel the operation. For example, while stopping Autonomous Database you see a message such as the following:

Manage Scaling with Concurrent Operations

Describes the impact on scaling operations when you initiate certain actions during an ongoing scaling request.

Action	Description
Stop	Stop pauses scaling. The scaling restarts when the database starts.
Restart	Restart pauses scaling. The scaling restarts when the database starts.
Restore	Restore pauses scaling. The scaling restarts when the restore completes if resources allow.
Switchover	Switchover pauses scaling. The scaling restarts when the switchover completes. The scaling also occurs on the standby database after the switchover.
Failover	Failover pauses scaling. The scaling restarts when the failover completes. The scaling also occurs on the standby database if it is available after the failover.
Terminate	Scaling stops and the database is terminated.
Change Database Mode Read-Write or Read-Only	A mode change pauses scaling. The scaling restarts when the database starts after the mode change completes.

Manual Backup with Concurrent Operations

Describes the impact on a manual backup operation when you initiate certain actions during an ongoing manual backup.

Action	Description
Stop	Stop cancels an ongoing manual backup. The manual backup does not restart when the database starts.
Restart	Restart cancels an ongoing manual backup. The manual backup does not restart when the database starts.
Restore	Restore cancels an ongoing manual backup.
Switchover	Switchover cancels an ongoing manual backup. The manual backup does not restart after the switchover completes.
Failover	Failover cancels an ongoing manual backup. The manual backup does not restart after the failover completes.
Terminate	The manual backup is canceled and the database is terminated.
