Hi,
I changed cpu_count parameter:
sql> Alter system set cpu_count=16 scope=spfile
sql> Alter system set parallel_threads_per_cpu = 2 scope=spfile
when I check the spfile, the parameters are realy changed... but when I check form database
sql> show parameter cpu_count
12 (the old number)
I understand that cpu_count and parallel_threads_per_cpu are dynamic parameter ... don't need to restart the instance... so what's wrong ?
My database version is :
Oracle Database 19c Enterprise Edition Release 19.0.0.0.0 -Version 19.13.0.0.0
