19c (New Feature) : Auto Space Management for Flashback Logs in the Fast Recovery Area (Doc ID 2465562.1)

Last updated on JULY 21, 2020

Applies to:

Oracle Database - Enterprise Edition - Version 19.1 BETA and later
Information in this document applies to any platform.

Purpose

 Starting with Oracle Database Release 19c, the management of space in the fast recovery area is simplified. Oracle Database monitors flashback logs in the fast recovery area and automatically deletes flashback logs that are beyond the retention period. When the retention target is reduced, flashback logs that are beyond the retention period are deleted immediately.

In scenarios where a sudden workload spike causes a large number of flashback logs to be created, the workload is monitored for a few days before deleting flashback logs that are beyond the retention period. This avoids the overhead of recreating the flashback logs, if another peak workload occurs soon after.

 

Scope

 The COMPATIBLE initialization parameter must be set to 19.0.0 or higher for flashback logs to be automatically deleted.
