Hi,we are running IFSAPP10 on a Oracle 19c Enterprise Edition Database, using Oracle PDB concept.There, we ran into severe issues while people just have been trying to populate one single Customer Order. While observing the database sessions, we noticed that the query has been parallelized, divided into several sessions. Strangely, these sessions sometimes have been blocking each other. As a summary, instead of improving the performance with parallelism, it caused a severe performance drop.To solve it, we switched off parallel query mechanism by setting Oracle parameter “parallel_max_servers” to 1 (was 400).Is there a recommendation from IFS how these parameters “parallel_max_servers” and “parallel_min_servers” should be set? Or, more generally spoken, how parallel query feature should be set up together with IFS Applications?Please also share your experience with Oracle parallel query mechanism, and with which settings it runs best for you. Thank you!Wolfgang
