DB CPU cannot be accounted for on 19c AWR

USER101Nov 2 2022 — edited Nov 2 2022

DBTIME_4.JPGDBTIME_1.JPGDBTIME_2.JPGDBTIME_3.JPGHello,
We recently migrated one of our databases from a 2 node RAC running 12c to Exadata running 19c. 19c is running on multi tenant architecture. Since the migration, I see the CPU usage has quadrupled on Exadata, the rate at which the messages are being processed has dropped but the funny thing is that I cannot trace where the CPU is being used. The SQL execution amounts to around 10% of the total CPU used..

Anyone seen this issue/behaviour before ?
