Query only runs fine with a previous optimizer version

user455466Feb 29 2024 — edited Mar 1 2024

Hi,

My company had migrated Oracle DB from 11g to 19c. Some queries doesn't run fine with the new version so I used the optimizer_features_enable parameter to shift the behavior of the optimizer backwards to the 11g release. Is posible to run the same query in 19c with 11g execution plan?

Attached are 11g and 19c execution plans.

plan_19c.txt

plan_11g.txt

Thanks in advance.

Regards, Jose Luis
