Query Having Function With a Parallel Hint is Not Using Parallelism

in PL/SQL (MOSC) 2 commentsAnswered

When we migrated from 12 to 19 some queries started running slow. Apparently on oracle 19c when you use a function in a query you need to add parallel_enable to be able to use parallel execution. Is there a way to disable this default behavior/feature other then reverting to a lower version with OPTIMIZER_FEATURES_ENABLE?

Howdy, Stranger!
