Increased log switches upgrading from 12 to 19

edited Jul 18, 2020 5:06AM in Database Administration (MOSC) 8 commentsAnswered

Hi,

Upgrading from 12.1.0.2 to 19.6.

I have a Materialized View refresh that generates 223 log switches in 12.1.0.2

DBMS_MVIEW.REFRESH('PWRPLANT.CR_ALL_DETAILS_VIEW_MV', method => 'c', atomic_refresh => FALSE);

After the upgrade to 19.6 it generates 487 log switches.....

Has anyone else experienced this?

Aside from accommodating the space is there anything I should be looking at?

Thanks

Ken
