Specification of UpdateBatchSize has been changed?

in Database DataWarehousing (MOSC) 3 commentsAnswered

I am using UpdateBatchSize to perform database update operations in Oracle 19c.

 

In versions prior to 12c, specifying a value for UpdateBatchSize improved the speed. However, in 19c, specifying a value seems to slow down the process.

 

Does anyone know how the specifications have changed?
