Last updated on APRIL 17, 2023

Applies to:

Oracle Database - Enterprise Edition - Version 19.10.0.0.0 and later
Information in this document applies to any platform.

Databases upgrade from 12.2.0.1 to 19.10.0.

Batch job is running slow and queries going for NL instead of HJ and going for high cpu utilization.

Found "alter table ... move partition" against the tables and found strange "last_analyzed" times in the stats-history.
