Updating partition details
For more information about A/B system updates and how they work, see Partition selection (slots).
A/B system updates provide the following benefits: A/B updates require changes to both the client and the system.
A/B system updates, also known as seamless updates, ensure a workable booting system remains on the disk during an over-the-air (OTA) update.The current slot is bootable when the system is running, but the other slot may have an old (still correct) version of the system, a newer version, or invalid data.Regardless of what the attribute set by the user space, which is relevant only if the slot is also bootable.Also see my notes on using dbms_stats.copy_table_stats for partitioned tables.To use incremental statistics for a partitioned table, the "incremental=TRUE" keyword must be set.
